Calculate two limits: the amount a lender may approve and the amount that leaves room for utilities, maintenance, savings and life outside the mortgage. Use the lower number when shopping.
How qualification is estimated
A common starting point keeps housing costs near 39% of gross income and total debt obligations near 44%, although lender and insurer policies vary. Housing costs typically include the qualifying mortgage payment, property tax, heating and part of condo fees.
The qualifying rate can be higher than the contract rate. Credit, income type and property characteristics may also affect the result.
Same price, different monthly reality
A downtown condo with fees, an older detached house with higher heat and maintenance, and a newer home in a growing area can carry different costs at the same purchase price. Property-tax assumptions also matter.
Use actual figures for the property when possible. Replace calculator defaults before relying on the result.

The lender maximum is a ceiling, not a recommendation.
