ARM – One Dollar Allowance

House15 Purchase

October 23, 2025October 21, 2025mrsonedollarallowanceLeave a comment

We last purchased a rental property in 2022, after most of our purchasing was done in the the 2019 era. We were busy with 3 kids, and I recently felt like I was coming out of the fog. Mr. ODA and I went to a wealth building seminar in the Spring; my intention was to have that seminar reinvigorate our desire to build our portfolio. It worked well for Mr. ODA, but once options started to show up, I started to panic.

We first went to an open house. It was a bit further away that I’d prefer to maintain a house, and there were a few red flags. For one, it frustrates me that landlords can fill out a seller disclosure claiming they know nothing about the house. I can tell you if I had any roof issues or major system issues in any of my houses, even though I haven’t physically lived there. Mr. ODA wanted to pursue it, but I couldn’t bring myself to get on board.

We were then sitting with his parents one night, telling the story of this open house, and his mom said that she saw a townhouse posted on Facebook that she thought we’d be interested in. It was owned by the son of an old friend of her’s. We asked our real estate agent if she’d show it to us, but she was out of town. So then his mom texted her friend to see if they were there and we could go look. They weren’t there, but they gave us the contractor box code (which is surprising in itself that there wasn’t a sentribox on the door). We went over and the house looked to be in good order, so we put an offer in. We like to surprise our agent with these types of things where all she needs to do is get the contract ratified.

UNDER CONTRACT

The house had been listed for some time when we came across it. It was was listed at $182,500. We offered $182,000 with $2,000 worth of seller subsidy on September 2, 2025. They agreed that day. We ended up needing to redo the contract because the wife wasn’t on the deed of the house, but she had signed the contract, but that wasn’t a big deal.

We had the inspection scheduled for September 10th. There was hardly any issues in the report, and we picked a few of the bigger things to ask for them to fix. They agreed to our list. They gave our agent a receipt showing they had paid someone to fix the items on our list. We did our final walk through the afternoon before closing and were disappointed to find that two of the bigger items (leaks) were not addressed properly and the house was dirty (including things left in the fridge and freezer). Our agent reported that to their agent, and they addressed everything that evening. We swung by the next morning before closing to see it all cleaned up and the leaks addressed.

The appraisal was ordered by our lender and came back at $188,000. That was a pleasant surprise to see we had immediate equity in it.

COMMERCIAL LOAN

We chose to go a commercial loan route. Interest rates aren’t falling as quickly as we expected to see. We have a commercial loan on one of our other properties in town, and I was still surprised to see how easy this process is. The loan qualifications are mostly based on the cash flow of the property. I filled out an application, submitted a ledger of our other property cash flows, and sent in 3 years worth of tax returns.

We were quoted at 6.74% interest. The loan terms are a bit different. Our last commercial loan was amortized over 25 years, but there’s a balloon at 5 years. This time around, it’s amortized over 25 years, but the balloon is at 15 years. A commercial loan also means that the taxes and insurance are not escrowed, and I’m responsible for paying them on my own.

The loan is an Adjustable Rate Mortgage (ARM) too. There was no different to us in the 3 year or 5 year ARM, so for the first time, we picked a 3 year ARM. In the past, it was related to securing our low rate. This time around, we’re expecting rates to drop in the near future, so we locked in our rate for only 3 years. It only changes on 3 year increments (some of the others will change every year after the initial lock period). It also has a clause that indicates the rate has a floor of 4%. I also don’t see a maximum adjustment that can happen (we have other ARMs that state an adjustment can’t be more than 2% at the change date).

We were expected to put 25% down. That would be $45,500 based on the $182,000 purchase price, and would leave 136,500 worth of a loan. They ran some numbers and determined that we could only qualify for a loan of $132,000 based on a rent of $1,400. They only us the cash flow to determine the eligible amount and not the rest of our portfolio. Let’s break that down to the fact that a loan of $136,500 equates to a monthly loan payment of 942.23, and a loan of $132,000 equates to a monthly payment of 911.17. So at a rent rate of $1,400, we could cover the monthly payment of $911.17, but we could not cover a monthly payment $31.06 higher. We pushed back for a second, but in the end it didn’t matter and we accepted the loan of $132,000.

PROS

When I look at this place, it feels like a place someone will rent. It’s clean, feels like home, and has a good layout. It has a closet available for a washer and dryer, which is a plus. Both bedrooms are upstairs and each has its own bathroom, and there’s a powder room on the main floor. It’s more secluded than other units in the complex, giving the occupant more grass area to hang out in the front and back.

CONS

We do have some concerns. The townhouse is at the back of the neighborhood. The entire rest of the community has parking right outside their front door. This group of 4 townhomes is separated from the parking lot, so you have to walk a bit further. The trade off there is that it’s secluded, you have a front “yard” (instead of pavement), and you’re more secluded from your neighbors.

I didn’t want another townhouse in our portfolio. With a townhouse, your value is strongly dictated by what your neighbors have done (or not done) to the property. As much as we don’t plan to resell these properties in a short time frame, I do have the thought that I want to be able to sell it when the time comes.

Also with a townhouse, you’re also at the whim of a community manager that is likely not putting utmost effort in. We asked about the HOA at closing and the previous owner said the cost used to be $35 per month. When it was that cheap, they weren’t paying their bills, so the lawn wasn’t mowed and the trash wasn’t removed. They increased the price to $95 two or three years ago, and that has made a difference in the community’s upkeep.

The HOA is due monthly, which is an inconvenience and a surprising process on their part. I plan to pay it monthly until I have confidence in their ability to process my payment and apply it to my account timely. After some time, I may pay in advance. I just went to process the first payment and planned to pay 3 months worth, but then realized that will create a harder tracking mechanism on me right now.

CLOSING

We had our closing on October 16th. It was super quick and easy. I listed the house for rent that evening.

SUMMARY

At this point, we have the house listed for rent at $1375. We had determined the range for rent during our purchase evaluation. Unfortunately, I hadn’t looked at the current market by the time we went to list, and there’s quite a bit out there. I’ve shown it to 2 people and have another showing today. One of the people from the weekend said they were seeing other places on Wednesday, so I’ll hold out on any changes to the rent price until this weekend.

Risk Taking

June 29, 2024mrsonedollarallowanceLeave a comment

We’ve hit some pretty big milestones financially. Mr. ODA casually mentioned a certain number by a certain age, but our goals were more associated with quitting our full time jobs. I quit my job in May 2019. We’re in a situation for a couple of years where we’ve been ready for Mr. ODA to quit, but we keep pushing the date back because his job isn’t preventing us from doing the things we want to do.

How did we get to the point where we replaced my income and I could quit working without scaling back anything financially? We took risks. Some of them were big ones. Some of them weren’t so big, but they felt big at the time. Most risks worked in our favor, but some did not.

RETIREMENT ACCOUNT LOAN

Mr. ODA and I both worked for the Federal government. Their version of a ‘401k’ is the Thrift Savings Plan (TSP). There were two loan options that were available: a primary residence loan or a general purpose loan. You then repay the loan back to your account with interest (the interest is paid into your account as well). When we took our loans, the rate was just over 2%. According to tsp.gov, the rate is currently 4.75%. There’s a fee of $50 to take a primary residence loan and a fee of $100 to take a general purpose loan.

While you’re missing out on the compound interest of your account when you take the loan, the ability to buy our own house, create that equity, and be at the beginning of our careers made the decision easy for us. We made extra payments during the repayment period, and we were able to adjust the regular payments up and down based on our financial needs each month. We have no regrets in our decision.

ADJUSTABLE RATE MORTGAGE

An adjustable rate mortgage (ARM) sounds scary. A variable rate. Most people are used to locking in a 30-year mortgage. I’d venture to say that most people also think they know what an ARM entails, so they don’t even consider it. We considered it. We looked into it in great detail. We couldn’t see why more people didn’t use it. We actually were very hesitant over this decision the first time because an ARM’s reputation is very negative. However, we took our time to lay out the numbers and see what would work best for us.

The first time we used an ARM, we knew we had no intention of being in the DC area for more than 5 years. By using an ARM, we saved thousands worth of interest in our mortgage payments over the three years we owned it.

There are several “fail safe” parameters in an ARM. For one, you do lock in a rate for some period of time. We considered 5 year, 7 year, and 15 year options. Then after that period of time, your rate can only adjust within the contractual terms. For example, we have one rate that can adjust 2% in either direction at the 5 year mark, and then 1% for each of the following 4 years after that, with a cap of paying a maximum interest rate of 7% (this is an old loan, clearly). The rate adjustments aren’t a given, and they’re adjusted based on the prime rate at that time, not based on the whim of the bank or the maximum it could increase.

We also ran the numbers based on the interest rates. An ARM’s incentive was that the interest rate is lower than the 30-year conventional loan rate. I don’t have the details since this post is more of an overview, but the ARM saved us money we paid towards interest. Interest is a higher percentage of those earlier payments in an amortization schedule. We either sold the house or paid the loan off early, so the ARM adjustment never came into play, and we saved all that interest cost.

BUSINESS/COMMERCIAL LOAN

A series of events had us asking a local credit union about loan options. They offered us a commercial loan. This one has a big catch though: there’s a balloon payment. Our loan is amortized over 30 years, which is how our payments are calculated. However, the balance of the loan is due at the 5 year mark. That balance is going to be about $175k. We have no plans to pay that off by that time (we aren’t even making extra payments towards it). We will refinance it. The pro here was that our interest rate for a loan closed on in 2022 was 3.625% (when mortgage rates were in the 5% range). Hopefully by 2027, interest rates are lower than they are today; this is a gamble at the moment.

PARTNER

There’s a cap in the “Fannie/Freddie” world of the number of mortgages a person can hold. That cap is 10. There was a point where we had completely leveraged ourselves and ran out of room. We had a Realtor friend interested in more rental properties, and he agreed to front our down payments, which we’d pay back with interest, and have a 50% share in the houses.

We signed an agreement with him that outlined our payments to him for the down payment he covered (which we paid off in about 3 months), and it established our 50% shares in the two houses purchased via this method. We purchased the houses in April 2018 and February 2019, and put them in a limited liability corporation (LLC). Each month, I collect rent from the houses and pay out our partner’s share. These houses don’t ask for much (one has been rented since before we owned the house and one has a tenant that has been there a few years), but if they need something, I handle coordinating the maintenance request. We should have set up a schedule where I’m paid for my time since Mr. ODA and our partner really don’t do anything for these houses, but luckily the requests are few and far between. We split all costs 50/50.

RENTERS WITH COMPENSATING FACTORS

I have several examples of entering into lease agreements with tenants that don’t have a perfect record. In these instances, we typically request some sort of compensating factor (e.g., a cosigner, an additional security deposit). We give everyone the chance to tell us about their financial and rental history before we run a background check on them (telling us doesn’t cost anything, but a background check does).

We had a prospective tenant not disclose a bankruptcy on her record. I could have immediately disqualified her and her husband, but I gave them a chance. They lived in that house for a year. They only moved because his job after grad school took them out of the area, but they set us up with a new tenant at their departure, and she stayed there for several years. Then they moved back to the area, and they requested a house of ours. We had one available, so we happily had them move into it. There’s one success story from giving someone a second chance.

I also have a couple that doesn’t have a happy ending. We had purchased a house without vetting the area. I had fully vetted a house two blocks away, but I learned my lesson that the crime of an area doesn’t need more than one block to change its ways. This house was in a bad area. The house itself was adorable. It attracted wonderful people to come see it, but they’d check the crime history of the area and decline applying (understandably). Someone came forward with a 448 credit score. That’s pretty bad. She wrote a really nice letter though. She disclosed everything up front and said she just wanted a roof over her and her son’s heads. I believed it. We then spent months and months struggling to get her to pay her rent, even offering her a payment plan several times and changing her lease structure to allow her to pay twice per month (hopefully eliminating the constant late fees she was accruing). We eventually gave her 30 days notice to vacate the premises due to lack of payment. She didn’t even make it a year. Instead of listing the property for rent, we ended up selling it. That was a whole other debacle where we entered into a contract to close by September of that year, but we didn’t close until the following January due to the lack of financial qualifications on the buyer’s end.

PAID OFF LOANS/MORTGAGES

This doesn’t appear to be a big risk. What could go wrong with paying off your mortgages? Well, if we didn’t have a cash reserve, and there was an emergency, then we paid off these loans with the cash on hand, leaving nothing to cover that emergency. However, those dooms-day concerns rarely come to life, and we had continued cash flow that replenished our accounts.

The positive here is that we freed up cash flow. Instead of having mortgage payments to make every month, we now have the cash to go into savings or towards any higher-than-expected bills. Besides the house we sold, we’ve also paid off 6 mortgages. That means that we’ve paid less interest to the banks, and that’s more money in our pockets.

We haven’t paid off any other loans because they’re all below 5% interest (they’re actually all below 4% except for 1 with our partner, and we would need his buy in the pay that off, which he hasn’t wanted to do). After payments to mortgages, our property manager, our partner, and utility payments, we have over $8,000 in cash flow per month. I will note that this doesn’t include things that I need to save up for each year to be able to afford (e.g., taxes and insurance), and it doesn’t include maintenance needs that crop up. Cash flow is important for us because if Mr. ODA quits his job, that’s less income to offset our regular personal expenses.

FINANCIAL AWARENESS

On any given day, we’re weighing several financial decisions fluidly. There are the givens that we have to pay the bills that are out there. I have to pay all the mortgages and utility bills. I weigh the best time of the month to pay each bill, which means that I may not pay them as soon as the statement arrives, but may wait until closer to the statement due date (but never carrying a balance unless it’s 0% interest). Then there are the options such as paying additional payments towards a credit card with a 0% interest rate, additional principal payments to a mortgage, or additional investment plans. We’re not looking to apply for any loans, so the $9k balance on a 0% interest credit card doesn’t have any attention of mine except the $500 I pay each month. I have it marked on my calendar when that 0% introductory rate expires, and I’ll have to pay the balance in full.

Our money is handled by a full, big picture, approach. Each day, there’s a chance that we come to a fork in the road and make a different decision because the variables changed slightly. We don’t put our money into “buckets” or “envelopes.” In my experience, people who handle their money like this end up overspending.

We hit our goal to replace my income well before our son was born, but then I kept working until he was 9 months old. While I was still working, we could have easily said, “we hit our goal, but since you’re still working, let’s put all that money into a slush fund of some kind.” When people see any “extra” money, they then look for their next splurge. They feel they deserve something for saving money instead of putting that extra money to work for you and your future.

There are those “autopilot” moments in our finances, but when it comes to making a big change, we put pen to paper and check the details. We aren’t going to take $100,000 out of our investment accounts to pay off a 2.5% mortgage. But one day, we will have to consider what to do with our loan that has a balloon payment, which shows it’s not a hard and fast rule that we won’t pay off anymore loans early (because if interest rates are still at 7.5% in 2027, it may not be worth refinancing that balance).

LIVE SMART WITH INFORMED DECISIONS

Take the time to make informed decisions and research the data for yourself. Run models with the projection of money to see for yourself if it works in your situation. Don’t spend your days listening to other people’s opinions on actions. If we had listened to opinions, we wouldn’t have taken a TSP loan or taken out ARMs.

We’re at over $4 million net worth, have a solid cash flow (which is important because if our net worth of $4 million was tied up in a retirement account, that wouldn’t give us the ability to live comfortably now), and have plenty of money going into accounts for the future (for both us and the kids). Our spending is managed regularly with an ingrained thought process. Take the small, first step for yourself without other people’s opinions weighing you down.

If you want to live differently from everyone else, you have to take action and think for yourself.

Mortgage Evaluations

March 18, 2021mrsonedollarallowanceLeave a comment

Rate Sheet Options from your Lender

When reaching out to a loan officer, there are a lot of options to choose from. I’m hoping to break down the decision-making here. I’ll share how we ended up with several different options, too.

Basically, it boils down to:

Put enough down to avoid paying Private Mortgage Insurance (PMI)
Don’t pay more than 20% unless there’s a decent incentive.
Don’t pick a loan term shorter than 30 years unless there’s a decent incentive.
Carefully evaluate any Adjustable Rate Mortgages (ARMs).

PMI

I broke down PMI in a previous post: PMI – Private Mortgage Insurance. We suggest doing whatever you can to meet the requirements to avoid paying this. The cost of PMI can be a couple hundred dollars per month, which is money that can be put towards the principal balance of your loan or other bills, rather than in the bank’s pockets. There are also hoops to jump through to remove PMI early, which may include paying for another appraisal on the house ($400-$700!).

LOAN TERMS

A conventional loan will likely require 20% to avoid paying PMI. There are some loan options out there that may allow a smaller down payment without a ‘penalty’ (e.g., PMI, higher interest rate), but 20% is the standard, and is usually required when purchasing an investment property.

There may be an option to put down more than 20% or you may think you can afford to pay a higher mortgage each month, so you’re interested in a shorter loan term. Unless there’s an incentive (e.g., lower interest rate, better closing costs), stick with the bare minimum to get the loan.

If there is an incentive, you’ll need analyze the math and your goals to determine if committing extra money to a higher down payment or a larger monthly payment is worth it. If you have extra cash each month, you can pay more towards your principal rather than pigeon holing yourself into a higher monthly payment. Plus, if you have more cash liquid, you may be able to purchase another rental property, which will increase your monthly cash flow.

While we evaluate the loan terms on every house purchase, I’ll share the details of the two most “unconventional” options we chose. Two things to note: 1) lenders add a ‘surcharge’ to the rate for it being an investment property, typically around 0.75%, which means the rates aren’t going to be the great, super-low, rates being advertised; and 2) the term “point” means a fee of 1% of the loan amount.

HOUSE #2

For House #2 (purchased in 2016), we were informed that if we put 20% down instead of 25%, the rate would increase 0.25% on average. If we assume a 30 year conventional loan, 20% down at 4.125% equates to about $69,700 paid in interest (assuming no additional principal payments); 25% down at 3.875% equates to about $60,800 paid in interest. By putting an additional $5,850 as part of our down payment, we saved about $9,000 in interest over the life of the loan.

Once we determined that we’ll put 25% down, we then had to figure out the appropriate loan length. On this particular offer, 30 year amortization wasn’t an option for us because we would have had to pay a point to get a competitive rate. We chose a 20 year amortization because the house already came with a well qualified tenant, we didn’t expect a lot of maintenance and repair costs due to the house’s age, and we didn’t have an immediate need for a higher monthly cash flow based on our place in life at the time.

While our long term goal was to have rental property cash flow replace our W2 income, this house was early in our purchasing. At the time, we were focused more on paying off House #1 (higher rate and a balloon payment after 5 years). Frankly, we didn’t truly understand the power of real estate investing at this time, and didn’t know how much it would accelerate the timeline for us to meet our goals. By decreasing our loan length, we increased our monthly payment, but also lowered the total interest paid over the loan’s life by over $22k. Since more of our monthly payment is going towards principal reduction than had it been a 30 year amortization, this loan isn’t on our priority list to pay off early.

HOUSE #3

For House #3, we evaluated the rate sheet for the loan term, interest rate, and down payment percentage again. This house was purchased a few months after House #2, so those rate decisions were fresh on our minds. We were quoted several options: 1) 20% down at 4.25% for 20 or 30 years, 2) 25% down at 3.75% for 20 or 30 years, or 3) 25% down at 3.25% with 0.5% points for 15 years.

As you can see, there’s no incentive to pick the 20-year term because it’s the same rate as a 30-year term. If we have additional cash, we can make a principal-only payments against the 30-year term rather than unnecessarily tying up our money.

At first, we thought paying points was an absolute ‘no.’ However, points aren’t a bad thing. Paying down your rate up front can save you an appreciable amount in interest. Plus, points are tax deductible.

Now for the breakdown of each options. Let’s say the house purchase was $110,000 (because it wasn’t an exact number, and it’ll just be easier to use a ‘clean’ number like this). Microsoft Excel has an amortization template where you can plug in the loan terms and see the entire amortization schedule.

Option 1: 20% down payment equates to a loan amount of $88,000; the annual interest rate is 4.25%; the loan is for 30 years, with 12 payments per year. If we make no additional payments, this totals about $67,800 worth of interest paid over the life of the loan.

Option 2: 25% down payment equates to a loan amount of $82,500 at 3.75%. If we make no additional payments, this totals $55k worth of interest paid over the life of the loan. This requires an additional $5,500 brought to the closing table, but saves almost $13k in interest. It also decreases our monthly principal and interest payment (i.e., not including escrow) from Option 1 by $50.

Option 3: 25% down payment, 3.25% interest, and 15 years (instead of 30 years) equates to just under $22k paid in interest. To obtain the 3.25% rate, it required “half a point.” If a point is 1% of the loan amount, that would be 1% of $82,500. This rate only required 0.5%, so that meant paying $412.50 as part of closing costs along with the additional $5,500 of down payment required for 25%. However, the shorter loan length means that monthly payment is increased (between Option 2 and Option 3, the difference is $197.63).

For about $6k, we pay a higher monthly payment, but we also save a significant amount of interest over the life of the loan. The short loan term of 15 years means this one is also not on our radar to pay off while we focus on paying down other, higher interest and higher balanced, mortgages. In this case, the benefits of the big picture math outweighed the increase in monthly payment.

We are five years in on this mortgage and are already seeing significant reduction in the outstanding principal due to the amortization schedule becoming favorable more quickly. In 10 short years more, our house will be fully paid for, through rent collection, without a single dollar of extra principal payments from our other financials. What a great feeling.

ADJUSTABLE RATE MORTGAGES (ARMs)

An adjustable rate mortgage can be beneficial depending on the terms and how long you expect to own the house. For us, we expect to hold our investment properties for a long time, so it wasn’t worth the risk of an ARM. Many times lenders won’t even offer an ARM on an investment. However, when we purchased our DC suburb home, we knew we didn’t expect to be there for more than 5 years, so we chose a 5 year ARM.

After a positive experience with that decision, we also chose an ARM on our second primary residence. We chose a 5 year ARM, even though we expected to be there longer than 5 years. We figured we would either accept the new rate, if there was one, at the end of the 5th year, or we would refinance when necessary. As a result, Mr. ODA monitored rates and refinance options over the last year or so. Unexpectedly, we sold that house 3.5 months shy of the end of the initial ARM term so we didn’t have to do anything.

I break down all the details of an ARM and our decision making in a recent post.

SUMMARY

When I reach out to my lender to ask what the rates of the day are and begin the process of locking a rate on a new loan, I ask for options. These options are in the form of a “rate sheet.” When you ‘lock’ a rate, you’re actually locking the ‘rate sheet,’ not the individual decisions of loan length and percent down. For every house, we evaluate the rate savings that can come from doing something less “conventional” than a 30-year fixed at 20% down mortgage. Our decision is based on what’s best for our goals and our cash in-hand.

As shown above, in our early decisions, we favored shorter loan terms for rate savings. but since House #3’s purchase, we noticed how much more we cared about low monthly payments and low down payments to allow us to buy more properties along the way. Every investment property loan since House #3 has been the ‘standard’ 30-year fixed at 20% down. Because of this perspective shift, we were able to buy six properties in 2017, which gives us about $2,000 in monthly cash flow that we can then use to pay down mortgages.

ARM – Adjustable Rate Mortgages

February 27, 2021mrsonedollarallowance2 Comments

An ARM is when the interest rate applied to the loan balance varies throughout the loan. The loan is typically amortized over 30 years like a conventional loan would be, but the interest rate is variable. There is an initial fixed interest rate for a pre-determined period of time (e.g., 5, 7, 10 years). The rate then adjusts based on prime rates, with a maximum amount allowed for the increase each period of time (e.g., a maximum 1% increase each year for 5 years). This is where people find ARMs alarming, but note these two important points: 1) an ARM can’t jump an egregious amount at the end of the initial fixed term (usually no more than 1% or 2% in one year, outlined by the lender at the beginning), and 2) the rate is based on interest rates at that point in time.

Usually, the benefit of an ARM is a much lower interest rate during the initial term. If you know that your ownership in the property will only be for 5, 7, 10, etc. years, then this is where the benefit is realized. Amortization schedules ‘front-load’ the interest** (e.g., your monthly payment is the same total ($500); your payment in year 1 will be broken out as $375 interest and $125 principal; year 20 will be broken out at $150 interest and $350 principal).

**Every dollar of your loan is being borrowed for a length of time determined by the outstanding principal on the loan. At the beginning of your loan, all 30 years are being borrowed, so the proportion of principal to interest of each monthly payment results in far more interest being paid. Every month you pay a little bit of principal, gradually decreasing your outstanding principal amount, meaning you are no longer borrowing it and will pay slightly less interest with each monthly payment.**

Therefore, if your interest rate for the initial term is less with an ARM than it would be with a fixed rate loan, you’re saving considerable interest for the time that you own the property. You’ll need to compare the interest rate savings during the discounted initial term of an ARM with the 30-yr fixed quote your lenders offers. Also evaluate an ARM based on how long you anticipate owning the house. If you’re looking to hold a property for more than 7 or 10 years, an ARM’s benefit is probably too risky since interest rates after that timeframe are unknown. Also, the more years your ARM offers for an initial fixed period, the less the discounted interest rate is.

In our current very low interest rate environment of 2020/2021, ARMs are rarely beneficial compared to a 30 year fixed rate.

An ARM is identified by 2 numbers. A 5/1 ARM means that the initial rate period is 5 years, and it can change every year thereafter for the life of the loan. A 5/5 ARM means that the initial rate period is also 5 years, but it can only change the interest rate every year for the 5 years after the initial term expiration. Here’s an example of a 5/1 ARM quote. It shows that the initial period is 60 months (5 years) and the maximum the rate could ever be is 5% more than the initial term, but that doesn’t mean there’s a guarantee of an increase since the interest rate is still based on the rate sheet at that time.

We found ARMs to be beneficial for our primary residences. We had several people try to talk us out of locking in an ARM. However, once we investigated the loan terms, we learned that there are strict parameters around your rate changes that absolved some of the risk others were using to dissuade us from the option. Yes, it’s a gamble, but interest rates have remained fairly steady or decreased over the last 10 years of our home ownership.

When we moved just outside of DC, the move was solely to get back to living together because our jobs had separated us. Being in the Federal government, the easiest way for both of us to get a job was the DC area, but we didn’t want to live in that metro area with the higher cost of living and a lot of traffic for very long. The rate terms offered were 4% on a 30 year fixed, or 2.5% on a 5 ARM. We owned the house for 3 years and 2 months. Over 38 months, we paid just over $23k in interest. Had it been the 4% on a 30 year fixed, it would have been over $37k in interest, which is a $14k savings. By paying less interest, that means that more of each monthly payment went towards principal than it would have, resulting in $4,700 more to principal. Additionally, by having a lower interest rate, our monthly payment was $250 less. Over 38 months that’s $9,500 less we had to pay, freeing it up to save and invest in other ventures.

For our second primary residence, we also had an ARM. We expected our time outside of Richmond, VA to be longer than the DC area, but not forever. I was uncomfortable with a 5/1 ARM and wanted the 7/1 ARM, but Mr. ODA picked the 5/1. We owned this house for 4 years and 9 months. Our interest rate was 2.875%. At the 61st month, it could have risen by 2% for the first year and 1% for each of the next 4 years. Had we gone with a conventional 30 year loan, the interest rate was going to be 4.125%; we would have paid $54k in interest during our ownership. With the ARM, we saved $17k in interest, put $5,300 more towards principal, and paid over $11k fewer in monthly payments.

We purchased our current residence a few months ago. We have a 30 year fixed conventional mortgage at 2.625%. Since interest rates are so low now (you can see how previously, we’d be around 4% for a conventional and got lower than 3% by choosing an ARM, whereas now interest rates are less than 3%) and we plan on being here for a much longer time, we didn’t pick an ARM.

As illustrated in the examples for the first two properties we lived in, ARMs can be a powerful option in strategizing your mortgage to work most efficiently for you. They are not without risk, so pros and cons must be weighed along with future forecasting of your life situation. If used in the best circumstances, they can help you shift tens of thousand of dollars away from interest and towards principal and other investments to aid in reaching financial freedom.
