The 7% mortgage changes the math

March 2023 · Market · 3 min read · by Kinan Sawar, MD — REALTOR® at Shorewest, REALTORS®

In barely a year, mortgage rates went from 3% to 7% — and quietly reset what every buyer in America can afford.

No single number reshaped housing faster than the mortgage rate. Its jump from roughly 3% to 7% rewired the market in months.

The payment shock

On the same home at the same price, a move from 3% to 7% raises the monthly principal-and-interest payment by well over 50%. Buyers didn’t get a discount to compensate — prices stayed high — so the entire increase landed on affordability.

A transaction recession

The fallout was a collapse in activity rather than price: priced-out buyers stepped back, locked-in sellers stayed put, and volume fell hard. A recession in transactions, not necessarily in values.

The new regime

This is the rate regime the market has been adjusting to ever since. Every trend that followed — the freeze, the lock-in effect, the affordability crisis — traces back to this one repricing.
