Home Affordability by Mortgage Rate

When the Fed raises rates, mortgage buying power collapses. A buyer with $2,500/month for principal and interest could afford a $466,000 loan at 5% in 2021 — but only $341,000 at 8% in 2024. This calculator shows your exact home price at four key rate points (5%, 6%, 7%, 8%) so you can see the rate-to-affordability tradeoff at a glance.

The Rule of Thumb — 10% Per 1%

Every 1% increase in mortgage rate reduces affordability by approximately 10% for the same monthly payment. Going from 5% to 8% is about a 30% affordability cut. This is why housing markets have been stuck through 2024-2025 — buyers who could afford $500K at 3% rates can only afford $370K at 7% rates, but homes are still priced for 3%-rate buyers.

Strategies in High-Rate Environments

(1) Buy now, refinance later: 'Marry the house, date the rate.' When rates drop in 2026-2027, refinance. Closing costs are typically 1-3% of loan, paid back in 1-2 years of savings. (2) Negotiate seller-paid concessions: builders frequently offer $10-15K in closing costs or 2-1 buydowns instead of price reductions. (3) Reduce loan size via larger down payment: increasing down payment from 10% to 20% reduces loan size by 10% — same effective benefit as a 1% rate drop.

What If Rates Don't Drop?

The base case for 2026-2027 is rates between 6.0% and 7.0% per Federal Reserve dot plot and bond market expectations. Don't bet your home purchase on rates dropping to 4-5% — that scenario requires a severe recession the Fed is actively avoiding. Plan for current rates as the new normal. If you can comfortably afford the home at today's rate, buy now. If you can't, wait or look at lower-priced markets. See our refinance savings calculator for when rates eventually move.
