How Temporary Buydowns Work

The seller deposits a lump sum at closing. You pay less each month. Here's the mechanics.

💲

Seller Funds an Escrow at Closing

The seller (or builder) deposits a lump sum into a custodial escrow account at closing. That deposit equals the total payment difference across all buydown years — calculated before you sign.

📈

You Pay the Reduced Rate Each Month

During the buydown period you make a lower monthly payment. The escrow releases the difference to the lender every month to make up the full P&I amount. Your loan still amortizes at the full note rate.

📅

Rate Steps Up on Schedule

A 2/1 buydown: rate is 2% below note rate in Year 1, 1% below in Year 2, then full note rate from Year 3 forward. The schedule is fixed — no surprises, no adjustable-rate risk.

🔄

Leftover Funds Reduce Your Principal

If you sell or refinance before the buydown period ends, any remaining escrow balance is applied as a principal paydown at closing. This is a key advantage over simply taking a lower purchase price.
