Buying a multi-family.

FAQ

Multi-family FAQ — what buyers ask

Direct answers about multi-family buying in the GTA. Specific numbers, Ontario regulations, 2026 market data.

• What's the cap rate for multi-family in the GTA in 2026?

  Stabilized purpose-built rental cap rates: 4.0%-5.0% for newer buildings (2010+), 4.5%-5.5% for 1970s-90s vintage, 5.0%-6.0% for older walk-up apartments. Smaller multi-family (5-19 units) trades 5.0%-6.5%. Cap rates have compressed slightly in 2025-26 as immigration drives rental demand. Toronto remains the tightest market in Canada.

• Is the Ontario Residential Tenancies Act friendly to investors?

  Mixed. Pros: annual rent increases are guideline-controlled (2.5% for 2026); evictions for legitimate reasons (own use, non-payment, demolition) are clear-path. Cons: existing tenants are protected — you cannot raise rent above guideline on continuing tenancies, and vacancy decontrol only applies when units turn over. Tribunal Ontario can take 8-14 months for an LTB hearing in 2026. Cash-flow analysis should assume below-market existing rents for the first 5-10 years.

• What's a typical gross rent multiplier (GRM) for GTA multi-family?

  GRM (price ÷ annual gross rent) ranges 14-18 for newer Class A purpose-built rental, 12-15 for 1990s-2010s buildings, and 10-13 for older 1970s walk-ups. Smaller multi-family (4-19 units) typically GRM 12-16. Always pair GRM with cap rate and replacement cost — Toronto replacement cost ($450-550/sqft for new construction) underpins the long-term floor.

• What should I review when buying a multi-family building?

  Full rent roll with each tenant's start date + last increase date (drives reset opportunities). LTB filing history (active or recent disputes). Reserve fund + capital plan — older buildings often need $30-50/sqft over 10 years for roof, plumbing, electrical. Phase I environmental. Pre-1990 buildings: confirm asbestos, lead paint, knob-and-tube remediation status. Always run the math at below-market rents for the first 5+ years.

• Can I convert a single-family home to a multi-unit rental in Toronto?

  Yes — Toronto's Multiplex Zoning (2023) permits up to 4 units as-of-right on most residential lots, with garden-suite added as a 5th in some wards. Conversion cost: $150-300k per added unit (kitchen, bathroom, fire-separation, separate hydro meter, egress). ROI typically 12-18% over 7-10 years if the lot supports four 2-bedroom units. Best targets: lots wider than 30' with rear-lane access.

• How do I evaluate a commercial property's cap rate?

  Cap rate = stabilized net operating income (NOI) ÷ purchase price. Calculate NOI by taking gross rental income, subtracting vacancy allowance (5-10%), operating expenses, property tax, and management fee — but NOT mortgage payments. Compare to current market cap for the property class + submarket. A property at 6.5% cap in a 5.5% market is either a deal or has hidden issues — investigate.

• What financing is available for commercial real estate in Canada?

  Standard commercial mortgage requires 30-40% down and amortizes over 20-25 years (vs. 25-30 on residential). Interest rates run 1.0-1.5% above 5-year GIC. CMHC-insured loans available on multi-family 5+ units — down to 15% down with insurance premium added. Vendor takeback (VTB) financing is common on $5M+ deals where the seller carries a second mortgage for 5-10 years.

• What's the typical due diligence process for commercial?

  30-90 day due diligence with conditions. Standard package: Phase I Environmental Site Assessment, property condition assessment (PCA), zoning certificate, rent roll + estoppels, tenant interviews (covenant strength), historical financials (3 years), Tenant + Service contract assignments, lease assignments. For industrial: add Phase II Environmental + soil testing. For multi-family: add LTB filing search. Budget $15-50k in third-party reports.
