What this screen still cannot decide

Will a lender qualify me?

Income treatment, other debts, credit, insurer rules, appraisal and the exact property still determine qualification.

Would I want to live there?

The owner unit, privacy, parking, sound, outdoor space and landlord responsibility remain home decisions.

Does the property deserve the price?

Legal configuration, leases, expenses, condition, insurance and future capital work need property-specific evidence.

Official guardrails

The rules behind the example

Owner-occupied three- to four-unit financing

CMHC Purchase currently shows up to 90% loan-to-value and a 10% minimum equity requirement for owner-occupied three- to four-unit properties, with a maximum purchase price or lending value below $1.5M. The page also publishes premium tiers and uses the greater of the contract rate plus 2% or 5.25% for GDS/TDS calculations.

Down payment and mortgage-cost basics

The Financial Consumer Agency of Canada explains down-payment thresholds, mortgage loan insurance, premiums and the fact that an insurance premium added to the mortgage also accrues interest. Product eligibility and lender requirements can be stricter.
