Rate Buydowns, Explained

Same House. Lower Payment.

A buydown pays some of your interest up front, often with the seller’s or builder’s money, so your monthly payment drops. Here is what that looks like on a real example.

3-2-1 vs 2-1 vs Regular Payment

Your loan is written at the market rate, but your payment starts lower and steps up each year. The difference is prepaid into an account at closing, usually by the seller or builder.

Principal and interest only. Taxes, insurance and mortgage insurance (such as FHA MIP on a 3.5% down loan) are extra. You qualify at the full market rate, and the buydown cost equals the total payment savings.

Builder Buydowns & Forward Loan Commitments

Large builders buy blocks of below-market mortgage rates from lenders in advance. It’s called a forward commitment, and it lets them offer buyers a rate far below the market for the entire life of the loan, not just the first few years.

How a Forward Commitment Works

01The builder pre-buys rates

Months ahead, the builder pays a lender to reserve a pool of loans at a set below-market rate.

02You use their lender

To get the rate you usually close with the builder’s preferred lender on a qualifying home by a set date.

03The rate stays for 30 years

Unlike a 2-1 or 3-2-1, it is a permanent rate, and it can make a newer home cost less per month than a resale.

What to watch for (we’ll check this for you)

Builder rates often apply only to certain homes, loan types or closing dates. The incentive may replace a price reduction or closing-cost credit, so we compare the true cost both ways. Rate pools run out, and lender fees and loan terms vary.
