Mortgage Points Are a Bet on How Long You Stay

Meta description: Discount points lower your mortgage rate for the life of the loan, but they only pay off if you keep that loan long enough. Here's how the math works and when to skip them.

You get the rate quote and there's a number next to it you weren't expecting. 1.125 points. Maybe 0.875. Your loan officer mentions you can buy the rate down, and suddenly the 6.875% you were quoted has a price tag stapled to it.

This is the part of the process where most people nod and move on. It's also where a few thousand dollars quietly gets decided.

Points aren't a scam and they aren't a trick. They're a trade. Whether it's a good trade depends almost entirely on one question nobody asks you at the closing table: how long are you actually keeping this loan?

Where the confusion starts

One point equals one percent of the loan amount, paid at closing. On a $450,000 loan, a point is $4,500. In exchange, the lender drops your interest rate for the life of the loan. It's prepaid interest. You hand over money now to pay less every month later.

The part people get wrong is the exchange rate. A point does not lower your rate by a full percent. The common shorthand is a quarter percent per point, and on a lot of days that's close, but it isn't a rule. Point pricing comes off a rate sheet that moves with the mortgage-backed securities market, and it changes every morning. Some days a point buys you 0.25%. Some days that same $4,500 buys 0.125%, which is identical money for half the benefit.

So ask what the point is buying today. Not what it usually buys.

Two different things are both called points

Look at page 2 of your Loan Estimate, Section A.

Discount points buy down your rate. Optional. That's the trade described above.

Origination points, or an origination fee, are what the lender charges to make the loan. Not optional, not a buydown, and paying them doesn't lower anything. It's the cost of doing business with that lender.

Both live in the same corner of the same page, which is how a borrower walks away thinking they bought a lower rate when they really just paid a fee. If your Loan Estimate shows points, ask which kind, and ask what your rate would be without them.

There's a third version that runs the other direction. A lender credit, sometimes called negative points, is where you accept a slightly higher rate and the lender puts money toward your closing costs. Same trade, reversed. Genuinely useful when cash is tight and you'd rather keep it in the bank.

The math, done out loud

A realistic example. $450,000 loan, 30-year fixed.

At 6.875%, principal and interest run about $2,956 a month.

Buy one point for $4,500 and take the rate to 6.625%. The payment drops to about $2,881. You save roughly $75 a month.

$4,500 divided by $75 is 60. Five years to break even.

Before month 60, you're behind. After month 60, you're ahead, and if you somehow hold the loan all 30 years you'd save close to $27,000 in interest.

That's the entire calculation. It isn't complicated. It's just rarely done in front of the borrower.

Now run it again at a worse exchange rate. Same $4,500, but today it only buys 0.125%, taking you to 6.75%. You save $37 a month. Break-even moves to ten years. Same cost, and now you'd have to sit on that loan through two presidential elections to come out ahead.

Break-even is a deadline, and plenty of people miss it

The break-even assumes you keep the loan. Two things end it early.

You sell. Most owners don't stay 30 years, and life changes in ways that don't consult your amortization schedule. A job, a baby, an aging parent, a divorce.

Or you refinance. This one deserves real thought right now. Freddie Mac's weekly survey had the 30-year fixed at 6.76% as of September 10, 2026, and industry forecasts have it staying in the high 6s through the end of the year. But forecasts are guesses, and a return to the 5s within a few years is not a wild scenario. If you refinance, the points you paid don't come with you. They're spent.

That's the real risk. Points are recovered only through time, and there's no refund for changing your mind.

When points tend to be worth it

Someone else is paying. Seller concessions and builder credits are common again in slower markets. If a seller kicks in $10,000 and you direct part of it to a permanent buydown, the math changes completely, because your break-even is immediate. Ask for it. Plenty of sellers prefer funding a buydown over cutting the price, since it costs them less and does more for the buyer's payment.

You're confident you're staying, and you can say why. A long-term home, a settled career, family nearby. "Probably a while" is not the same answer.

You need the lower payment to qualify. Sometimes a buydown is the difference between an approval and a denial, usually on debt-to-income. That's a legitimate reason to pay points. Just be honest that you're buying an approval, not making an investment.

When to skip them

• You'll likely be in the home five years or less.
• The cash would otherwise go toward your down payment. A larger down payment can lower your loan-to-value and knock out mortgage insurance, which often beats a quarter point.
• You'd have no reserves left after closing. Points come out of the same pile as your emergency fund, and the emergency fund is more important.
• Your break-even lands well past the point where refinancing starts to look likely.

First-time buyers with limited cash: points are usually the wrong home for your last dollar.

Points versus a temporary buydown

These get mixed up constantly, and they are not the same product.

A 2-1 buydown lowers your payment for two years, then the payment steps up to the full note rate. The money sits in an escrow account and gets released monthly. It's a payment subsidy, usually funded by a seller or builder.

Discount points change the note rate permanently.

A temporary buydown is fine when a seller is paying for it and you understand that year three shows up on schedule. It gets risky when the buyer funds it themselves, or when the plan depends on refinancing before the payment resets. You have to qualify at the full note rate either way, so the question isn't whether you can afford the higher payment. It's whether you've planned for it.

The tax angle is smaller than it sounds

Points are prepaid interest. On the purchase of a primary residence, they're generally deductible in the year you pay them if you meet the conditions in IRS Topic 504. On a refinance, you normally spread the deduction across the life of the loan, so $4,500 on a 30-year refi works out to $150 a year.

Here's what usually gets left out: you only benefit if you itemize. The 2026 standard deduction is $16,100 for single filers and $32,200 for married couples filing jointly, and most households don't clear that bar. If you take the standard deduction, the tax treatment of your points is worth nothing to you.

It can be real money for some borrowers, particularly larger loans in high-tax states. Ask your CPA before you count on it, and don't let a deduction be the reason you buy points.

What to do this week

Ask your loan officer to price the same loan three ways: zero points, your current quote, and one point. Same day, same lock period. Put the payments and the upfront costs next to each other.

Do the division yourself. Upfront cost divided by monthly savings equals months to break even. If that number is longer than you plan to keep the loan, you have your answer.

Ask what a point buys today. If it's 0.125% instead of 0.25%, it's not a good week to buy points.

Compare lenders at the same point level. This is the one that costs people the most money. A 6.5% quote with 1.5 points is not better than a 6.75% quote with none, and lenders know which number goes in the ad. Ask every lender for a no-point quote so you're comparing the same thing. APR helps, but remember APR assumes you keep the loan the full term, which is the exact assumption in question.

Ask whether the seller will pay for it. The worst thing that happens is they say no.

Before you sign

Points are a fine tool. They're just a tool with a timeline attached, and that timeline belongs to you, not to the lender.

The question was never "is 6.625% better than 6.875%." Obviously it is. The question is whether you'll still own this loan in five years, and whether $4,500 does more good sitting in your rate or sitting in your savings account.

Run the numbers. Ask what the point buys today. Compare apples to apples.

One more thing worth knowing. Rate sheets change every morning, and the pricing you were quoted last Tuesday may not exist today. If you're weighing points, have that conversation close to when you're actually locking, not weeks ahead of it.

That's a conversation we have every day at Convoy Home Loans. Send over the Loan Estimate you're holding and we'll walk through what those points are actually buying you.
