What this means for you
If you're buying
You must qualify at this rate (or your contract rate + 2%, whichever is higher), so a higher stress test shrinks the mortgage you qualify for — even if your actual rate is lower.
If you're selling
A tougher stress test means fewer qualified buyers, which can soften demand for higher-priced homes.
