Canada rental property mortgage in 2027: down payment rules, rental income qualifying, and CMHC
Buying a rental property in Canada requires a minimum 20% down payment and a different income-qualifying approach than a primary residence. This guide covers the 2027 rules for 1–4 unit properties, how lenders use rental income to calculate TDS, and the CMHC-insured multi-unit exception.
Investing in rental property in Canada means navigating a different set of mortgage rules than your primary residence — larger down payment minimums, rental income qualifying caps, and the stress test applied on top of both debts simultaneously. The rules changed meaningfully in 2024–2025, particularly for short-term rentals and the use of Bank of Canada-linked variable-rate HELOCs to fund investment purchases.
Down payment requirements by property type
| Property type | Owner-occupied? | Min. down payment | CMHC-insurable? |
|---|---|---|---|
| 1 unit (pure rental) | No | 20% | No |
| 2–4 unit, owner-occupied | Yes (1 unit) | 5–10% (sliding) | Yes |
| 5+ unit (multi-family) | Optional | 15–25% (lender varies) | Via CMHC commercial |
| Vacation property (non-rental) | Occasional | 5–20% (varies) | No for pure vacation |
How rental income is counted: three lender methods
Lender adds 50–80% of gross monthly rental income to your qualifying income. Simpler but requires evidence of market rents (appraisal or lease). Used by most major banks for owner-occupied 2–4 units.
Rental income offsets the property's carrying costs in the TDS ratio instead of adding to income. Result is similar but mechanics differ — useful when rental income is modest.
Uses actual net rental income from your CRA tax return (Schedule T776). Requires 2 years of rental history. Most conservative — large deductions reduce qualifying income significantly.

Common questions
What is the minimum down payment for a rental property in Canada?
For a non-owner-occupied investment property (pure rental), Canadian lenders require a minimum 20% down payment — CMHC insurance is not available for straight investment purchases. However, if you plan to live in one unit of a 2–4 unit property, you can access CMHC-insured financing with as little as 5% down (for purchases under $500k) or 10% (for the portion above $500k). The CMHC premium table shows rates for owner-occupied 2–4 unit properties.
How do Canadian lenders count rental income for mortgage qualification?
The treatment of rental income varies by lender. Most use one of three methods: (1) Add-back method — add 50–80% of gross rental income to your qualifying income; (2) Rental offset method — use rental income to reduce the rental property's share of your TDS ratio; (3) Net rental income — use the property's net income after expenses from Schedule T776 on your tax return. The OSFI B-20 guideline sets the framework lenders must follow when using rental income for qualification.
Can I use a HELOC on my principal residence to fund a rental property down payment in Canada?
Yes, this is a common strategy — borrowing against your principal residence equity via a HELOC to fund the down payment on a rental property. However, lenders will include the HELOC payment in your TDS calculation for the rental property qualification. The Bank of Canada has flagged this practice as a source of systemic leverage risk. The Bank of Canada's mortgage market reports track HELOC-funded investment property purchases as a share of total originations.
Are there special mortgage rules for short-term rental properties (Airbnb) in Canada?
Yes — and they tightened significantly in 2024. Most major Canadian lenders now restrict or exclude short-term rental income (Airbnb, VRBO) from qualifying income unless the property has a documented 2-year history on tax returns. Several lenders require the property to be in a licensed STR zone. Some municipalities (Vancouver, Toronto) have banned STRs in non-principal residences, which affects both the revenue model and lender willingness to finance. CMHC's Housing Observer tracks short-term rental stock and its effect on long-term rental supply.
What is the rental income tax treatment in Canada?
Rental income in Canada is fully taxable as regular income on Schedule T776. You can deduct mortgage interest, property taxes, insurance, maintenance, management fees, and depreciation (CCA — capital cost allowance). The CRA does not allow you to claim a rental loss created by CCA to offset other income — but you can carry the loss forward. CRA's Rental Income guide (T4036) covers all deductions, CCA rules, and how to report rental income on your return.
Does the mortgage stress test apply to rental property purchases in Canada?
Yes. The stress test under OSFI B-20 applies to all residential mortgage originations at federally regulated lenders, including rental properties. You must qualify at the higher of your contract rate + 2% or 5.25%. For rental properties, this means both your primary residence mortgage and the rental property debt are stress-tested simultaneously in your TDS calculation.
