Today, I have a great article from a reader, Rob from Mustard Seed Money. Rob was able to pay off his $400,000 mortgage in just 7.5 years, all before he was 32 years old. Below is his story, enjoy!

I was one of those weird kids that couldn’t wait to graduate from college.  I’ve always had a long-term focus and viewed college as a stepping stone.  One day during my freshman year, I remember walking to class with a friend saying that I couldn’t wait to graduate and start making some money. 

My friend turned to me with an incredulous look and confessed he planned to live it up while he could.

Needless to say, I probably didn’t enjoy college as much as others did.  

I had too strong of a focus on life after college to ensure that I’d reach the life goals that I had set up for myself. I wanted to obtain a good job, get married, buy a house and fill it up with some kiddos.  

Of course, what actually ended up happening did not follow the order that I had envisioned.  But, I can honestly say I love the way things turned out.  

I graduated from college in three years and right after the dotcom bubble burst.  As I’m sure you know, there weren’t a ton of jobs floating around at the time.  But I obtained one at an insurance company and was making a decent salary.

If you’re looking for a flexible way to earn more and put that money toward debt, savings, or even your mortgage, I recommend checking out how I made $302.80 in one week playing games on my phone. It’s a real side hustle I tried myself, and it’s surprisingly easy to get started.

 

My Gracious Parents

Fortunately, I was able to live at home with my parents.  Even better, they didn’t charge me rent.  I convinced them that if I lived at home that I could take the money that I would have paid towards rent and apply it towards the down payment for a house.  

They agreed that this was a good plan.  I started to save up money as quickly as possible.  Within two years, I was able to accumulate $80,000 for a down payment and started to look for houses in my price range.  

I quickly learned that the housing market had exploded since I went to college.  My parents’ house, which they had bought five years earlier, was now worth three times what they had paid.  There I thought I had a great, sizeable down payment to put into a luxury home, and then reality hit me.

An Overwhelming Mortgage

It took me about a year from the time I started looking to find an amazing townhouse.  It was brand-new, so there would be very little maintenance.  Plus, the HOA would the upkeep of the exterior of the home, which meant that I wouldn’t have to do any sort of yard work.  As a 23-year-old kid with other priorities, this sounded amazing.  

So they loaned a 23-year-old $400,000, who barely made 10% of that.  

Keep in mind, this was the early 2000s.

The downside to this amazing townhouse was that the only way that I could afford it would be if I brought in a roommate.  As an introvert, I was both terrified and excited.  In one sense, I would essentially have built-in friends to hang out with.  On the other hand, I would become an instant landlord and would have increased responsibility as a result.

My Mom’s Advice

My Mom assured me that by adding a couple extra roommates, I would be that much closer to paying off my home quickly.  They were able to pay off their home in 5 years, so I had some great inspiration to look to.

Initially, I was skeptical.  A lot of the experts say that you should never pay down your house.  They tout mortgage interest as a tax deduction and that the difference can be invested.  As a finance major in college, I knew how important it was to invest in the stock market early in order to benefit from compounding interest.

If there is anything that I remember from a college course, it’s when one of my professors said, “Time in the market is more important than timing the market.”  With all that great advice, I’m sure you know what I did.  

I ignored the experts and listened to my mom, like any good son would.  

Plus, I hated the thought of debt holding me down.  In my home growing up, debt was considered taboo, and I have also always been risk-averse.  While I didn’t anticipate exactly how debt would trap me, I did know that if I didn’t address it, that I would be regretful in the future.

Roommate Search

So adhering to my Mom’s advice, I began pursuing potential roommates.  I approached a co-worker as well as some friends from college.  They eagerly jumped on board (the rent was very reasonable), and I had the house full even before I bought it.  So I was all set, or so I thought.  

Since I had never lived with these guys before, I had no idea of their eating/sleeping/cleaning habits.  Quickly, I found out that we needed a housekeeper desperately.  Four guys living in one house with nobody volunteering to vacuum or clean created a mess.  

Sure, it may have been normal to have empty Doritos bags strewn all over the floor and a video game looping in the background in a college dorm.  But this was no longer going to suffice.  I now owned the property and was proud of that accomplishment.

Needless to say, we didn’t entertain any ladies for the first few months until we hired a maid.  But after that, it was smooth sailing.  Everyone under my roof was appreciative of her cleaning services every other week.

During the first few years of having roommates, I really enjoyed it, much more so than my experiences in college.  It also helped that the guys were paying me every month to live there.  Plus, the super low rent kept them content and staying there.

Chipping Away at my Mortgage

In the meantime, I was receiving enough from the guys’ contributions that I was making a dent in my mortgage debt.  I created my own loan amortization schedule.  At work, I would play around with the spreadsheet to see how rapidly I could pay off my debt.  

I became obsessed.  I’d run all these different scenarios, incorporating extra principal payments and their effects on my outstanding mortgage balance.  I couldn’t wait for raises and bonuses as I had planned to put any excess money towards my mortgage.  Any shaving of a month or two off the duration of my loan was a win in my book.

I figured out that I could pay off my 15-year mortgage in as little of 7.5 years if I diligently kept pouring money into the mortgage.  However, admittedly, after a couple of years of doing so, I started to get a little burned out.

Eyes on the Prize

The roommates weren’t getting along nearly as well as they had in the past.  Between their bickering and my introversion, the situation felt less than enjoyable at times.  Everyday though, I would have to remind myself to keep my eyes on the goal, which was being debt-free.  

I wrote down all the things that I would do when I became debt-free.  I would travel to Europe without any worries.  Because I wouldn’t be dependent on the paycheck, I would take more chances at work life.  In the future, my spouse wouldn’t have to take on an anchor of debt, and she could focus on her passions instead of having to support a massive mortgage that I had unwisely taken out.  

Looking back, I honestly have no idea how I did it.  

It definitely wasn’t always peaches and cream living with roommates.  There were times when my roommates (grown men) would throw Haymakers at each other while they were drunk.  There were times when they would wrestle, and I thought I would have to patch up holes in my wall (thankfully they actually never caused any damage).  But, I am so glad that I endured those uncomfortable moments.  While at times, it may not have been enjoyable, I’m able to look back now and get a good laugh at some of my roommate’s antics.  I love to tease my former roommates with these memories as now many of them are married with kids.  Oh, how a little maturity can go a long way!

Life Post-Mortgage

Though it felt like an eternity at times, I finally paid off my mortgage in 7.5 years.

I had proposed to my wife, and we planned to have our wedding at the end of September.  My last roommate also was planning to be married, but in early September.  So he moved out, I took his final rent payment, and I paid off my house.  This meant that when my wife and I married, my wife moved into a debt-free home.  

As a celebration, we went to Europe the following spring.  

I soaked it all in, from exploring Norway, where my family descended from, to visiting Spain to see a close friend.  All were incredible memories that I will never forget.  But the best part of it all was seeing Europe debt-free.  This was definitely the way to do it.  I highly recommend being able to plan the trip of a lifetime without having to worry about expenses.  It makes for a much more enjoyable experience.

A New Job

Shortly after I returned from the trip, an opportunity presented itself at work to take a huge leap that was outside of my comfort zone.  If I still had the mortgage, I would not have taken the job because I would have been afraid of failing and potentially losing my job.  

The boss didn’t have the best reputation, and the office had some morale problems.  Typically, I would look at those situations and think, “No way do I want to take a role like this where there is a 99% chance that I will fail.”

So, why did I take it?  I loved the work that was being done in the office.  I knew that if we could institute a couple of tweaks, that we could turn this office into a high performing machine.  

Without a mortgage, I felt able to dive into this new role.  

Here’s the crazy part– I crushed it.  I had no fear, so I implemented changes to the job that I thought were necessary.  Even crazier, I received a promotion and found myself in more roles that were out of my comfort zone.  My career trajectory has completely changed, all because I paid off my mortgage and in return became fearless.

Flexibility for My Wife

Paying off my mortgage turned out to be a huge blessing in an unexpected way.  My wife’s familial situation had led her to become a full-time caregiver for her special needs sister.  If we still had our mortgage, it would be much harder for us financially to have my wife stay at home to care for both her sister and our son.

While it’s not always easy being a stay-at-home caregiver, my wife loves the flexibility that has resulted from not having a mortgage.  

We have friends that have told us their wives would stay at home too if they did not have mortgages.  After hearing that, my wife always thanks me for the sacrifices that I made along the way, and in turn I thank my mom for encouraging me to do it.

Missed Stock Market Gains

Finally, there is the issue of how much I could have made in the stock market instead of paying into my mortgage.  Well, I recently recalculated the returns that I would have received if invested in S&P 500.  I would have made 3.6% with dividends.  

In comparison, my mortgage rate, including the tax benefits, would have yielded 3.5%.  So while the market beat paying off my mortgage by 0.1%, it wasn’t worth the difference to me when you take risk into account as well.

So I believe my extreme long-term focus has paid off.  We are currently reaping the benefits.  The sacrifices I made over the years have resulted in a better lifestyle for my family.

I definitely recommend paying off one’s mortgage if you want to experience greater financial freedom.

    I went with a 15 year fixed. With the interest rates super low I figured I’d take advantage and not worry about interest rates potentially rising in case something happened in the future. My biggest extra payment was at the very end when I got a bonus and paid it completely off 🙂

  2. Jason Williams

    Awesome news rob. I’m thinking about purchasing my first home and this gives me so much encouragement. I’m debating back and forth on whether I should save and rent or just put down on a mortgage. I believing putting down is the wiser option in the long run, but fear is stopping me. This was seriously motivational. Thanks so much!

    1. Mustard Seed Money

      I”m glad you enjoyed the article. Paying off our house has been a tremendous blessing and I’m definitely glad that we did it!!

    Your story is an inspiring one. Not having mortgage debt to contend with must be liberating for you and your wife. I have a rental home and planned to sell it and was quickly reminded that I would have to pay capital gains tax. According to my CPA, based on my taxes in 2016, had I sold the home in 2016, my capital gains would have been at least 50% or $150,000….that’s a lot of money. One option I was considering was moving back into it but then I have the dilemma of my current home mortgage. Perhaps I should focus on how to pay two mortgages instead of handing over $$$ to Uncle Sam. I don’t want to purchase another rental as we plan to retire soon. What would you do?

    1. Mustard Seed Money

      Thanks for sharing America’s HR Coach!!! Sounds like you have quite the dilemma although a good one if you’re going to have a profit on your rental property. If your rental property is currently generating revenue and you can swing two mortgages. It seems like it may set you up nicely in the future. Although if you do move into your rental property as your primary residence for two years, you would be able to exclude $250,000 if you’re single or $500,000 in capital gains if you’re married. You’ll have to share what you end up doing.

    You’re welcome!!! Glad to help.

  6. Tim Kim @ Tub of Cash

    Wow, super impressive Rob. Paying off your mortgage in 7.5 years. What a BEAST! You made the right decision. Even in hindsight, it was the right decision. It would be so awesome not having a mortgage! That mental relief is awesome, in and of itself I bet.

    1. Mustard Seed Money

      Thanks Tim!!! It has been by far the best thing that I’ve done financially and something that from my experience that I encourage all my friends to do as well.

  7. DNN

    Paying off that kind of money in less than 8 years is an absolute blessing. In today’s age of finance and information technology, you definitely need a side hustle working from home or anywhere online in being a digital nomad, so you can easily supplement your income as an affiliate marketer with or without a day job. Hats off to you for satisfying that kind of dent in under 10 years. 🙂

    1. Mustard Seed Money

      Thanks DNN!!! I was really lucky that I could rent out the house to roommates. Without their help I never would have been able to pay off the house in the time that I did.

  8. Michael Butts

    Thanks for telling us the ups and downs of renting out extra rooms. Sometimes these motivational recaps leave out all the bad stuff.

    I do have a question on how you raised the down payment: If you were making $40,000/year, how did you accumulate $80,000 in two years?

    1. Mustard Seed Money

      In college I was able to save money from working and investing in the stock options. I don’t recommend it but it was incredibly lucrative with all of the volatility back in the early 2000s. This helped supercharge my downpayment

  9. Tyler DeBroux

    Taking on roommates and charging rent for extra income to help pay off your mortgage was a great idea! I own a duplex and have a roommate that’s an old friend of mine from highschool. Between my tenants living in my duplex and my roommate who lives with me, I also use that rental income towards my mortgage. Great post, thanks for sharing!

    1. Mustard Seed Money

      Sounds like you are doing something similar to what I did. It’s definitely worth it in the long run, although there were definitely a couple of trying moments having roommates. But looking back it was definitely the right decision.

  10. Marleigh

    Love it. I read these stories to keep me motivated. My mortgage is seriously a tiny fraction of what yours was, but I’m still determined to pay it off in the next 4 years so we can also have that piece of mind. We have no other debt and love the debt free lifestyle so all we would have to worry about would be healthcare costs and day to day stuff. We hope that it will at least allow us to do semi-retirement on our terms. Thanks for the great story.

    1. Mustard Seed Money

      Wow four years will fly by. It may not feel like it but it will definitely come quicker than you expect and that feeing will be incredible. Keep up the awesome work!!!

  11. Mustard Seed Money

    Thanks L.A. Glad you enjoyed the article.

  12. Alaya@Hope+Cents

    Love this. Great inspiration for not following the conventional advice of holding onto a mortgage for all the “benefits.” Sharing in my newsletter! 🙂

    You graduated college, spent 2 years saving and another year looking for a house, which you bought at 23. So you graduated college at 20? And you said you were making a little over $40k a year but were able to save 80k in 2 years. How did you manage that?

    1. Lisarincon

      Hi Daysha,

      He was living with his parents and he didn’t pay rent. It sounds like he saved every single penny.
      I am also paying off the mortgage asap, in 6.5 years. I have one year left!

  14. Cameron

    Im 25 years old have a farm payed off as well as my college degrees. I cultivate apples, blackberries, strawberries and looking at getting a license to cultivate cannabis for medical use (3,000 sqft greenhouse produces at 6 harvest of cannabis a year is a potential for $580,500) not including the harvest profits of the fruits either. I live off my land I also get free gas from a well underneath my land. I’ve never taken out a loan either I saved up my money from working and investing. I’m looking at moving into buy land and real estate to rent out.

    “Well, I recently recalculated the returns that I would have received if invested in S&P 500. I would have made 3.6% with dividends.”

    Seems like more education in how stock returns work is needed.
