10-item due-diligence checklist. We can pre-flight most of these for you on a CMA call.
Comparable sales
Ask for 3–5 recent solds within ~1 km and the same beds/baths so the list price has context.
Property condition
Roof age, furnace age, hot-water tank age, electrical panel size, windows. Cosmetic vs structural.
Zoning
Confirm zoning matches your intent (single-family vs duplex vs secondary suite vs commercial).
Suite legality / potential
If suited or being marketed as suited: confirm permits, separate entrance, ceiling height, egress windows.
Monthly carrying cost
Mortgage + property tax + insurance + condo fee (if any) + utilities. Compare to your max budget.
Property taxes
Confirm the annual tax amount on the current assessment — and whether a reassessment is pending.
Insurance estimate
Get a same-day quote. Older homes, knob-and-tube wiring, polybutylene plumbing, flood plains all change the number.
Commute
Drive it (or transit it) at the actual time of day you'd commute. Map ETA lies during peak hours.
Deposit and financing conditions
Deposit size, financing condition window, condition removal date, possession date — all negotiable.
Inspection considerations
Budget for a home inspector ($500–700) and any specialty inspections (sewer scope, mould, asbestos for pre-1990 builds).
