This home is a bit unique, so there are not enough closely comparable homes nearby for me to trust an automatic number, and I would rather give you a real one than a wrong one. Tell me you are interested and I will pull the most comparable recent sales and send you a straight answer on price, usually the same day.

What the listing highlightsThese are claims from the listing. The only way to know for sure is to see it in person, and I am happy to book you a private showing.
- Separate entrance / basement suite: rental or in-law income potential, if it is legally registered and retrofit-compliant.
- Walk-out basement: natural light and strong in-law or income potential.
- Ravine lot: privacy and premium value, but confirm the buildable area and any conservation limits.
- Tall ceilings: they transform how a home feels, worth confirming the actual heights room to room.
- Premium lot / gardens: lot size and privacy hold value and cannot be changed, verify frontage, depth, and any easements.

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.
