FAQ

Frequently Asked Questions

Answers to common questions about the purchase cost calculator

What costs should I include beyond the mortgage?

Property tax, heating, condo/strata fees, and home insurance at minimum. Lenders use these in your GDS ratio, so leaving them out overstates what you qualify for.

Why do I fail GDS/TDS on a home I can afford?

The ratios use gross income and the stress-test rate, not your contract rate. The calculator shows which ratio fails so you know whether to raise income, cut debts, or lower the price.
