5 Homebuying Mistakes One Buyer Made (And Fixes)

A listener wrote in feeling stuck.

She bought a Brentwood, Tennessee townhome in 2023 for $445,990, has made roughly $120,000 in housing payments over three years, and has paid down about $12,000 of principal. Today, comparable homes are selling around $442,000.

She looks at those numbers and wonders whether buying was a mistake.

We don't think it was. But her story exposes several decisions every buyer should think through before closing, because a few different choices might have left her with more flexibility today.

The Short Version

To understand what actually happened, let's go back to the decision she made in 2023.

Since she asked us not to use her real name, we'll call her Dolly.

Dolly bought a Brentwood, Tennessee townhome for $445,990 with 5% down. The seller gave her a $10,000 credit, which she used for a 2-1 temporary buydown on a 7.375% note rate. Her payment today is $3,411 plus a $180 HOA, putting her around $3,600 all in.

Three years later, comparable homes are selling around what she paid. She has made roughly $120,000 in housing payments and paid down about $12,000 of principal. Meanwhile, her life has changed. She got married, they want to start a family, the townhome feels small, and they're considering moving out of state in the next one to two years.

Looking backward, she sees plenty to second-guess. But the useful question isn't whether she can find decisions she would make differently today. It's what those decisions can teach the next buyer, and what she should do from here.

The first lesson starts with something she admitted herself.

Mistake 1: Betting on the refinance as a sure thing

Her own words were: "I'd be lying if I wasn't banking on rates coming into the fives."

That's the first problem.

For years we believed mortgage rates were likely to settle lower than where they are today. At some point, though, you have to accept that the market may not cooperate on your timeline.

Most U.S. mortgages are 30-year fixed loans with no prepayment penalty, so if rates fall enough and you still qualify, you can refinance.

The word that matters is if.

Can you live with the mortgage you are taking today if rates don't give you the refinance you want next year, or even several years from now?

If the only way the home works is a refinance within 24 months, it doesn't work.

Hope you get the refinance. Structure the purchase so you don't need it.

We wrote more about that in our take on waiting for lower mortgage rates.

Mistake 2: Taking a temporary buydown without comparing the alternatives

A 2-1 buydown often gets marketed like a lower mortgage rate.

It isn't.

Dolly's note rate was 7.375% from day one. The $10,000 seller credit funded an account that subsidized part of her payment. In year one, she paid an amount calculated as though the rate were 5.375%. In year two, 6.375%.

But the actual mortgage was always based on 7.375%.

As the subsidy ran down, the mortgage payment did not change. What changed was who funded it. The buydown account paid part of it early on. Eventually Dolly became responsible for all of it.

That distinction becomes really important when refinance opportunities show up.

During Dolly's buydown period, there were windows where refinancing was worth evaluating. Some buyers looked at those opportunities and said, "Why would I refinance? My payment is lower right now."

They're comparing the new loan to the wrong number.

The proper comparison is the new loan against the full contractual payment and note rate on the existing mortgage, while also accounting for closing costs and whatever happens to the remaining buydown funds.

A refinance may still not make sense. But you don't reject it simply because the temporary subsidy is still reducing the amount coming out of your checking account.

When the window opens, run the math. The next opportunity might not show up for another year or two.

What could she have done instead?

One alternative was a permanent rate buydown.

Dolly's roughly $424,000 starting loan meant that $10,000 represented about 2.4 points. Depending on the lender's pricing that day, those funds may have purchased a meaningful permanent rate reduction.

We cannot say exactly what rate she would have received without seeing the original rate sheet. That's the point.

Someone should have shown her both options:

Then she could decide which structure made sense for her expected timeline.

We break those structures apart in mortgage rate buydown explained.

The third option: take the price cut

She also could have asked for the $10,000 as a straight price reduction.

If the seller were equally willing to reduce the price by $10,000, she'd have bought at $435,990 instead of $445,990.

With 5% down, that would have reduced her starting loan by roughly $9,500 and reduced the cash needed for the down payment by about $500.

The monthly-payment benefit would have been smaller than a major rate buydown, but she would also have started with a lower purchase price and a smaller mortgage.

None of these options is automatically right.

The mistake is presenting only one.

A good lender shows you the choices, explains what each one accomplishes, and structures the decision around how long you realistically expect to own the home.

That's exactly the kind of thing we work through on a Roadmap call.

Mistake 3: Not thinking far enough ahead about life

When you buy a home, you should buy with the end in mind.

Are you likely to get married? Have kids? Change careers? Relocate? Need another bedroom? Want a yard?

Dolly couldn't have known exactly how her life would unfold, but those possibilities matter when you're choosing both the property and the financing.

This is also why we almost never recommend a five-year ARM. Five years sounds like a long time until you're three years in, still own the house and rates haven't moved the way you expected.

Then the clock starts getting loud.

Do you sell? Refinance? Stay longer than you wanted? Make a career decision around the house because you're worried about qualifying later?

A seven- or ten-year fixed period can provide much more runway when an ARM makes sense in the first place.

The property matters too.

Single-family homes generally appeal to a broader buyer pool. Condos and townhomes can be more sensitive to HOA dues, special assessments, insurance, lending restrictions and competing new construction. Those issues can affect both resale and appreciation.

Brentwood was extremely popular during the pandemic, and additional supply may have helped keep this part of the market flatter than Dolly expected.

The bigger lesson is simple: spend as much time thinking about how you'll leave the house as how you'll buy it.

People will call 23 lenders trying to save $10 a month and won't spend two hours discussing the actual life decision with their family.

That's backwards.

Mistake 4: Confusing a loss with a bad decision

This is where I think Dolly is being too hard on herself.

She bought for $445,990. If she sells around $440,000, there may absolutely be an economic loss once selling expenses are included.

That does not mean buying the home was a mistake.

She has made roughly $120,000 in housing payments, but those payments weren't all supposed to become equity. Interest, property taxes, insurance and HOA dues were the cost of having somewhere to live, just as rent would have been.

About $12,000 went toward principal and increased her ownership in the property.

Could renting have been the better financial decision in hindsight?

Maybe.

But hindsight gets information Dolly didn't have in 2023. She didn't know exactly when she'd meet her husband, when they'd want children or whether an out-of-state move would become attractive.

She made a reasonable decision with the information she had.

If she sells today and loses some money, that is disappointing. It still may be the right move if the townhome no longer fits their life.

A loss is not the same thing as a mistake.

For the honest version of this math, we like our episode on whether buying a house is a good investment.

Mistake 5: Repeating the pattern on the way out

There are two traps in her plan from here.

The first is trying to grow the next down payment in the stock market when she expects to need the money in one or two years.

When the timeline is that short, the return of your money matters more than the return on it.

The stock market may go up. It may also be down 20% exactly when the right house appears and you need the cash.

Money you'll need soon is generally better matched to liquid, lower-risk options such as a high-yield savings account, money-market fund or short-term Treasury bills.

You are not trying to maximize the return on that money anymore.

You're trying to make sure it's there when you need it.

The second trap is getting locked onto 20% down.

We helped a listener in Arkansas who was short on gift funds and panicking because he thought he had to reach 20%. With an 800 credit score and 15% down, reducing the down payment saved him about $25,000 in cash and added roughly $93 a month in mortgage insurance.

That was an easy trade for him.

Twenty percent is not a magic number. If using 15% instead leaves you with $25,000 of reserves for moving, furniture, repairs, emergencies and life, compare the actual cost before automatically dumping the money into the house.

If you're weighing that trade-off, our breakdown of what PMI actually costs is a good starting point.

She got the rental decision right

Dolly also asked whether she should keep the townhome and rent it when they move.

The numbers aren't attractive.

Comparable rents are around $2,200 a month against approximately $3,600 of monthly carrying cost. That's roughly $1,400 a month of negative cash flow, or almost $17,000 a year, before accounting for repairs or vacancy.

Yes, some of that mortgage payment reduces principal. The property could appreciate later. Taxes can affect the economics too.

But she'd need a compelling reason to willingly feed the property that much money every month just because she doesn't want to sell near what she originally paid.

That is where sunk-cost thinking gets dangerous.

You've already spent the money. The question today is whether owning the property from this point forward is the best use of your money.

You don't owe the past a break-even.

Selling a property at a manageable loss so you can move into a home that better fits your marriage, family plans and future can still be the financially smarter decision.

Josh has directly closed more than 1,300 loans, and one pattern shows up constantly: smart people do most of this thinking alone and then wonder why they still feel uncertain.

Dolly thought through nearly every piece of this. What she needed was someone to put all the choices next to each other and help her see the trade-offs.

With one to two years before they expect to move, she now has something incredibly useful.

Time.

Stop guessing what you can really afford

It starts with a Discovery Call, a straight conversation about your real numbers. Josh and his team show you the price range and loan options that fit, and map out every step to closing. They handle your loan directly, never a referral, so you tour with confidence and write offers sellers take seriously.

Frequently Asked Questions

Is a temporary buydown or a permanent buydown better?

It depends on your timeline and the pricing available when you lock.

A temporary 2-1 buydown does not change your note rate. Seller funds temporarily subsidize part of the payment. A permanent buydown uses money up front to actually reduce the note rate for as long as you keep that mortgage.

A price reduction is a third option.

Compare all three based on how long you expect to own the home and keep the loan.

Should I count on refinancing to a lower rate later?

No.

Refinancing is an option, not a plan you should need in order to afford the house.

If rates eventually fall enough and you still qualify, refinancing may improve the loan. But your employment, credit, income, equity, property and market conditions can all change.

Buy a home using financing you can live with even if the refinance never arrives.

Should I refinance while I'm still in a 2-1 buydown?

Maybe.

Don't compare the new payment only to the temporarily subsidized amount currently coming out of your checking account. Your original mortgage payment is based on the full note rate, with the buydown account temporarily funding part of it.

Compare the new loan with the full economics of the old one, including the note rate, contractual payment, remaining subsidy, refinance costs and how long you expect to keep the new loan.

Is selling my house near my purchase price a loss?

It can be.

Even if the sale price is close to what you paid, selling costs may leave you with less money than you originally invested.

But losing money does not automatically mean buying was a mistake. Your housing decision also provided somewhere to live, and your life may have changed in ways you couldn't predict.

The relevant question is whether keeping or selling the house is the better decision from today forward.

Should I keep my down payment in the stock market before buying?

Be very careful if you'll need the money within a year or two.

Stocks can produce higher long-term returns, but they can also be down substantially when you need the cash. Short-horizon down-payment money is generally better suited to liquid, lower-risk places such as high-yield savings, money-market funds or short-term Treasury bills.

Do I really need 20% down to buy a house?

No.

Twenty percent avoids mortgage insurance on many conventional loans, but that doesn't automatically make it the best use of your cash.

Compare the monthly cost of mortgage insurance with the value of keeping additional cash available for reserves, repairs, moving expenses and other goals.

What is the sunk cost fallacy in real estate?

It's allowing money you've already spent to control a decision that should be based on what happens next.

If keeping a property means contributing $1,400 every month to cover negative cash flow, the fact that you originally paid more for it doesn't make holding it the right decision.

Evaluate the property from today forward. You don't owe the past a break-even.
