Temporary Mortgage Rate Buydown Guide
Reviewed by the Savora Finance Editorial Team · Last reviewed 2026-07-31
Learn how temporary mortgage rate buydowns change early payments and what happens when the reduced rate expires.
What this decision involves
A temporary buydown lowers the effective payment for an introductory period while the underlying note rate remains unchanged. The arrangement can ease early cash flow, but the borrower must still qualify under the lender’s rules and be ready for the later payment.
Factors to compare
- Length of reduced-payment period
- Source of buydown funds
- Final note rate
- Payment increase schedule
- Likelihood of refinancing or moving
Practical example
A 2-1 structure may reduce the effective rate for two years before the payment reaches the full note-rate amount.
Five-factor decision test
- Cost: include fees, taxes, and opportunity cost.

Common mistakes
- Using headline numbers without reading the terms
- Ignoring taxes, fees, or timing
