Rate buydowns vs. price cuts: which discount is worth more?

When homes sit unsold, sellers — especially builders — reach for incentives. Increasingly, the incentive isn't a lower price; it's a mortgage rate buydown: 'We'll pay to lower your rate to 4.99%!' Buyers hear a smaller monthly payment and get excited. But a buydown and a price cut are just two different ways of handing you the same pile of money, and which one is actually worth more depends on math most buyers never run.

The two flavors of buydown

A permanent buydown pays discount points to lower your rate for the life of the loan — roughly 1% of the loan amount buys about 0.25% off the rate (it varies with the market). A temporary buydown, like the popular '2-1,' lowers your rate 2 points in year one and 1 point in year two, then reverts to the full note rate. Temporary buydowns are much cheaper for the seller — which is exactly why they're the one you'll be offered most often.

The head-to-head math

That's the entire decision in one variable: how long will you keep this exact loan? Long horizon and rates unlikely to fall below your bought-down rate → buydown wins. Short horizon, or you expect to refinance when rates drop → take the price cut (or closing-cost credit) instead.

Why sellers push buydowns

• It protects the comps. A price cut becomes public record and drags down the value of every other home the builder is selling in that neighborhood. A buydown doesn't.
• It sounds bigger than it is. 'Rate as low as 4.99%' moves more buyers than '$12,000 off,' even when the dollar cost to the seller is identical or smaller.
• Temporary buydowns are cheap. A 2-1 buydown on a $400,000 loan costs the seller roughly $9,000–10,000 — far less than the price cut that would produce the same emotional effect.
• It can require using their affiliated lender, whose rate might be padded to begin with. Always compare their 'bought-down' rate against an outside lender's ordinary rate.

How to negotiate this like a pro

1. Convert every incentive to present-day dollars: ask the lender for the exact cost of the buydown being offered. Now you're comparing $ to $, not vibes to vibes.
2. Ask for the seller credit as flexible closing-cost credit instead — you can then choose to spend it on points, closing costs, or (with some lenders) a price reduction.
3. Get a loan estimate from an outside lender to check whether the builder's lender is competitive before the buydown.
4. Run three scenarios — sell/refi in 3 years, 7 years, and never — and see which incentive wins in each. Pick based on your honest most-likely case.
5. If you take a temporary buydown, bank the payment difference in years one and two. If the money's real, you'll have a cushion; if you spend it, the year-three reset will hurt.

One incentive, three structures, side by side

To make the comparison concrete, here's the same $15,000 of seller money applied three ways to a $405,000 loan at a 6.5% note rate — estimated figures, rounded. The temporary buydown produces the most dramatic early payments; the price cut produces the most durable equity; the permanent buydown wins only if the loan survives long enough to earn it back.

One more wrinkle worth pricing: the temporary buydown's subsidy sits in an escrow account and is spent only as you make payments, which is why unused funds are typically credited back if you refinance. The permanent buydown's cost is spent the day you close — it's gone regardless. That asymmetry is why temporary buydowns pair tolerably well with a genuine refinance plan, while paying permanent points and then refinancing two years later is simply burning the seller's gift.

And whichever structure you pick, verify the qualification detail: lenders qualify you at the note rate for temporary buydowns, and at the bought-down rate for permanent ones. That's not trivia — it changes how much house the same income can finance, which is exactly why builder advertising leans so hard on the phrase 'rates as low as.'

The bottom line

A buydown is neither a gift nor a gimmick — it's a prepaid interest discount whose value depends entirely on how long you keep the loan. Convert every offer to dollars, compare it honestly against a price cut, qualify yourself at the real rate, and remember: the seller chose the incentive that's best for them. Your job is to check whether it's also best for you.
