Who Has to Pass the Stress Test?

Nearly every buyer applying for a mortgage from a federally regulated lender must pass the stress test, including insured and uninsured mortgages, though some credit unions and private lenders follow slightly different rules.

Because you are qualifying at a higher rate than you will actually pay, your approved mortgage amount typically ends up 15 to 20 percent lower than if you qualified at your real contract rate, which surprises many first-time buyers.

Does the Stress Test Apply to Mortgage Renewals?

If you switch lenders at renewal you generally need to pass the stress test again, but if you stay with your existing lender and simply renew, most lenders do not require you to requalify at the higher rate.
