You want to house hack—live in one unit and rent out the others to cover your mortgage. Or maybe you're building an investment portfolio and multi-units offer better cash flow than single-family homes. Either way, financing duplexes, triplexes, and fourplexes works differently than single-unit properties. Here's what you need to know. Why Multi-Unit Properties? Multi-unit residential properties (2-4 units) offer unique advantages: For Owner-Occupants (House Hackers) Rental income covers part or all of your mortgage Lower down payment than pure investment Build wealth while living essentially "free" Learn landlording with minimal risk For Investors Better cash flow than single-family rentals One property = multiple income streams Economies of scale (one roof, one lot) Potentially easier management (all units in one location) Down Payment Requirements Down payments vary by occupancy and number of units: Owner-Occupied (Living in One Unit) Minimum Down Payment Duplex 5% Triplex 10% Fourplex 10% Owner-occupied means you live in one unit as your principal residence. Non-Owner Occupied (Pure Investment) Minimum Down Payment Duplex 20% Triplex 20% Fourplex 20% No CMHC insurance available for investment properties. How Rental Income Is Counted Lenders count rental income to help you qualify, but not at 100%: Typical Rental Income Calculation 50% Rule (Conservative): Lender uses 50% of rental income Accounts for vacancies, maintenance, management Add-Back Method: Add 50% of rents to your income Subtract property expenses Example: Triplex Purchase Your income: $80,000/year Two rental units: $2,500/month combined Rental income credited: $2,500 × 50% = $1,250/month or $15,000/year Effective income for qualification: $95,000 Qualification Considerations Debt Service Ratios With rental income factored in: GDS (Gross Debt Service): Housing costs ÷ Gross income ≤ 39% TDS (Total Debt Service): All debts ÷ Gross income ≤ 44% Multi-unit rental income helps these ratios significantly. The Stress Test You still must qualify at the stress test rate (contract rate + 2% or benchmark, whichever is higher). Property Appraisal Lenders appraise based on: Comparable sales Income approach (rent × capitalization rate) Condition and location Financing Options Conventional Mortgage (CMHC Insured) For owner-occupied: Lower down payment possible Best rates available CMHC premium applies Must be 1-4 units Conventional Mortgage (Uninsured) For investment or 20%+ down: 20% minimum down Competitive rates Standard qualification Portfolio/B-Lender When conventional doesn't work: Flexible income verification Credit-challenged borrowers Higher rates, more options Commercial Financing For 5+ units: Different qualification criteria Commercial mortgage rates Assessed as business, not residential Key Considerations for Multi-Unit Buyers Legal Conformity Ensure all units are legal: Proper zoning Building permits for conversions Fire code compliance Separate addresses/units in tax records Warning: Illegal suites can be shut down, destroying your rental income. Utility Separation Separate meters simplify landlording: Tenants pay own utilities Easier expense tracking More accurate cash flow projections Financing the Extras Multi-units often need: Larger reserves for repairs Property management budget Vacancy allowance Insurance considerations Exit Strategy Know your options: Sell as multi-unit Convert to single-family Condo conversion (where allowed) Multi-Unit Due Diligence Checklist Before buying, verify: ✅ All units are legal and permitted ✅ Zoning allows current use ✅ Current rent rolls are accurate ✅ Tenant leases are transferable ✅ Utilities are appropriately metered ✅ Fire/safety requirements are met ✅ No deferred maintenance issues ✅ Insurance is available and affordable ✅ Property taxes reflect multi-unit status What's Next Multi-unit properties are a powerful wealth-building tool.

A: Lenders are cautious about this. Arm's-length tenants are easier to document. Q: What if I want to live in one unit now but rent it later? A: You can change to full investment later, but may need to refinance if your mortgage was owner-occupied only. Q: Do I need landlord experience? A: No, but lenders may ask about your management plan. Consider property management for your first property. Q: How does condo multi-unit work? A: Some condos are split into multiple units but sold as one. Rules vary—verify with condo corporation. Q: Can I use RRSP funds for down payment on a multi-unit? A: Yes, through the Home Buyers' Plan if it's owner-occupied and you're a first-time buyer. Q: What about 5+ unit buildings? A: These typically require commercial financing, which has different criteria and rates.
