Affordability & Mortgage
Income needed assumes a ~32% GDS ratio; weekly is mortgage principal & interest only. Price ÷ income is the home price over the income needed. Fixed reference assumptions so listings compare on equal footing, not a lending decision.

Talk to Team Asgarian about your options
Rates and programs change often. We will connect you with a trusted mortgage professional and build a plan that fits your budget and goals.
Estimates only, not a mortgage quote or pre-approval. Figures use Canadian semi-annual compounding, current minimum down-payment rules, CMHC premium tiers, and Ontario (plus Toronto, when selected) land transfer tax. Actual rates, taxes, insurance, and closing costs vary by lender and property. Confirm every number with your mortgage professional.
Investor snapshot
Income potential: the basement has a separate entrance, which often supports a rentable in-law or second suite. That can lift real rent well above the figure above and help carry the mortgage. Ask us about permitted use in this area.
Thinking of this home as an investment? We will pull real comparable rents and run the full numbers with you.
Talk about the numbersEstimates only. Rent is modelled on above-grade size and local norms, so a finished basement or second suite (a separate entrance often means one) can push real rent well above this. Taxes, fees, and vacancy vary by property, and cap rate is before financing. A starting point, not a final number, let us run the real ones with you.
