Builders frequently offer rate buydowns as sales incentives to move inventory. A builder-funded buydown can save you thousands more than an equivalent price reduction, because you benefit from lower payments on the entire loan for years rather than a one-time discount.
Builder Incentive Types
Common builder incentives include: paying for temporary buydowns (2-1 or 3-2-1 structures), permanent discount points, closing cost assistance, upgrades and options at no charge, and price reductions. The smartest incentives are usually the ones that reduce your monthly payment rather than the purchase price.
Buydown vs Price Cut
A $10,000 price cut on a $400K home reduces your payment by roughly $60/month (at 7%). Using that same $10,000 to buy down your rate by 0.75% reduces your payment by about $170/month and saves you more over time. The buydown wins unless you sell within the first few years.
Negotiation Tips
Ask the builder: what is the total incentive amount, and can it be applied to rate buydowns? Compare the builder's preferred lender offer with your own lender's pricing. Some builders inflate the rate to make the incentive look bigger. Get a loan estimate from your own lender to compare apples to apples.
