What the test is doing
The lender runs your payment at a stress rate rather than your contract rate, then checks whether your income still covers housing costs and total debts within their ratio limits. If it does not, your maximum loan drops.
The two ratios that decide it
Gross debt service compares housing costs to income. Total debt service adds every other monthly obligation - car loans, credit lines, student debt, and card minimums. Both have to land inside the lender's limits at the stress rate.
- Mortgage payment plus property tax and heat
- Half of condo maintenance fees where applicable
- Minimum payments on every credit facility you hold
- Support payments and co-signed obligations
How to get more room
Paying off or closing an unused credit line often buys more approval than an extra few thousand in down payment. A longer amortization, a co-applicant, or moving to a lender with different ratio policy can also change the answer.
When it can be lighter
Some lenders and some renewal or switch scenarios are treated differently. That is exactly the kind of policy difference worth checking across several lenders before you assume your number is fixed.
Frequently asked questions
- Does the stress test apply at renewal?
- Staying with your current lender at renewal generally does not require requalifying. Moving lenders may, depending on the program.
- How much does it reduce my budget?
- For most files it trims the maximum purchase price noticeably. The exact amount depends on income, debts, and down payment.
- Can I avoid it?
- Not on insured or federally regulated lending. Some credit unions and alternative lenders apply their own policy - text us and we will tell you where your file fits.
