The $1,000 mortgage mistake first-time buyers must avoid

Lenders have a pitch that sounds almost too good to refuse. Pay a little extra at closing, they say, and you lock in a lower rate that saves you money every month for the life of your loan. For first-time buyers already stretched thin, that certainty is hard to pass up.

But for many buyers, paying mortgage points turns out to be a costly mistake. The savings are real. The problem is most buyers sell, refinance, or move before they ever collect them.

What mortgage points actually are

A mortgage point is a fee paid upfront at closing equal to 1% of the loan amount. On a $400,000 loan, one point costs $4,000. In exchange, the lender reduces your interest rate, typically by 0.125% to 0.25% per point. The monthly savings are modest. The upfront cost is not.

The question every buyer needs to answer before paying points is simple: how long will it take to earn that money back? That number is called the breakeven point, and it is the most important calculation in the entire mortgage points decision.

The formula is straightforward. Divide the cost of the points by the monthly savings they generate. The result is how many months you need to stay in the home, without refinancing, before the points pay off. Sell or refinance before that date, and you lose money.

How the math plays out

Take a hypothetical buyer purchasing a $450,000 home. She locks in a 6.75% rate, then pays two points ($9,000) to buy it down to 6.25%. Her monthly payment drops by roughly $156. That feels like a win.

But at $156 in monthly savings, it takes about 58 months, nearly five years, just to break even on the $9,000 she spent. If she sells at year four for a job transfer, she has lost close to $2,000 and drained reserves she may have needed for repairs or emergencies.

Now consider what she could have done with that $9,000 instead. Invested at a historical average stock market return of around 7%, that money grows to roughly $12,600 over five years. The points generated just $7,000 in savings over the same period. The opportunity cost alone makes the trade a loser.

Why the breakeven rarely arrives

The core problem is that buyers underestimate how long they will actually stay put. According to Redfin, the typical U.S. homeowner now stays in their home for 12 years. That sounds like plenty of time to break even. But 12 years is the median across all homeowners, heavily influenced by older, long-tenured owners.

First-time buyers move sooner. They are younger, earlier in their careers, and more likely to face job relocations, growing families, or income shifts. Many also refinance within the first few years when rates drop. Every refinance wipes out the benefit of the original points entirely. The CFPB recommends buyers model multiple tenure scenarios before committing to points, precisely because the outcome hinges on how long the loan stays in place.

What lenders do not always tell you

Lender pitches for points focus on lifetime savings, assuming a 30-year hold. A pitch that says “save $30,000 over the life of your loan” is technically accurate. It just does not mention that you need to hold the loan untouched for all 30 years to collect it.

Red flags to watch for when a lender is pushing points hard:

If they show you the 30-year number but not when you actually start winning, ask for it explicitly.Urgency pressure. Points offers do not expire overnight. A lender creating artificial urgency is a lender who does not want you to do the math.No mention of refinancing risk. If rates drop and you refinance within a few years, the points are gone. Any honest presentation includes this scenario.Only one loan estimate. The CFPB recommends getting at least three Loan Estimates.

For buyers who want a lower rate without the upfront risk, there are better options. Lender credits work in reverse: you accept a slightly higher rate in exchange for cash back at closing, offsetting other upfront costs. You preserve liquidity for repairs and emergencies that almost always hit in year one.

Builder buydowns are worth asking about in new construction. A 2-1 buydown temporarily reduces your rate for the first two years, with the cost paid by the builder. For buyers using FHA or VA loans, competitive rates are often available without paying points at all.

The one question to ask before paying points

Before agreeing to pay points, ask your lender for a written breakeven worksheet showing the exact number of months required to recoup the cost. Then model three scenarios: what happens if you sell in three years, five years, and seven years.

Closing costs already run 2% to 5% of the loan amount. On a $400,000 purchase, that is $8,000 to $20,000 before a single point is added. Draining reserves further to chase a rate reduction that may never pay off is one of the most common and preventable mistakes first-time buyers make.

The monthly payment is not the only number that matters. The breakeven date is. Know it before you sign.
