Buydown strategy
Is a mortgage buydown worth it?
A buydown is worth considering when its payment benefit solves a real need and the cost does not crowd out reserves, closing cash, or a better concession. The answer changes with the type of buydown.
Lenny's take
A buydown may be worth it if you understand the full payment path and the savings survive a realistic timeline test.
For permanent points, that means calculating break-even. For a temporary buydown, that means confirming the future full payment and comparing the subsidy with other uses of the same money.
Four tests
- Timeline test. Will you keep the mortgage long enough to benefit?
- Cash test. Will the upfront cost leave enough reserves and cash for closing?
- Payment test. Can you afford the permanent payment after a temporary subsidy ends?
- Alternative-use test. Could a lender credit, seller credit, or lower price create more value?
Signals it may be worth it
- You receive a permitted seller or builder subsidy and prefer payment relief over another concession.
- Your permanent-points break-even is well inside your expected holding period.
- The lower payment helps without weakening reserves.
- The quote is aligned with a zero-point baseline and has no offsetting fee increase.
Signals to slow down
- You may sell or refinance before break-even.
- The temporary payment is affordable but the full note-rate payment is not.
- You are spending most of your available cash to buy the rate down.
- The lender has not shown the same loan at zero points.
- The seller-funded buydown replaces a more useful closing-cost credit without a clear reason.
