This guide explains how mortgages for rental and investment properties work in Canada, from the first rental to a portfolio of several: the down payment rules, how lenders qualify you, how rates compare, where the down payment for a second property usually comes from, and the financing strategies investors use as they grow. It is part of WealthNorth’s guide to investment property financing.
Rental property vs principal residence mortgages
| Feature | Home you live in | Rental you won’t live in |
|---|---|---|
| Minimum down payment | As little as 5% with default insurance | 20% (no high-ratio insurance) |
| Rate | Insured mortgages are generally priced lowest | Usually uninsured, sometimes with a rental premium |
| Stress test | Applies | Applies at federally regulated lenders |
| Rental income | Only if part of the home is rented | Part of the expected rent counts toward qualifying |
| Interest deductible? | No, unless the borrowing is used to earn income | Yes, against the rental income |
| Tax on a gain when sold | Usually sheltered by the principal residence exemption | Capital gain, 50% included in income |
Down payment by property type
A home you won't live in needs at least 20% down: high-ratio mortgage insurance (less down) is only for a home that you, or a spouse, partner, parent or child living there rent-free, will occupy, CMHC insures two- to four-unit rentals only up to 80% of the value, and a one-unit rental can't be insured at all; if you live in one unit of a two- to four-unit property, an insured mortgage with a smaller down payment is available.| Property | Minimum down payment | Notes |
|---|---|---|
| One- or two-unit home, owner lives in one unit | 5% on the first $500,000 and 10% on the rest (insured) | The basis of house hacking |
| Three- or four-unit home, owner lives in one unit | 10% (insured) | CMHC’s maximum loan-to-value falls to 90% at three or four units |
| Any one- to four-unit rental you won’t live in | 20% | No high-ratio insurance; CMHC’s small rental loans also stop at 80% of the value |
| Five units or more | Set by the commercial lender or CMHC multi-unit program | Qualified mainly on the building’s income; see multi-family investing |
CMHC also insures loans on two- to four-unit rentals the owner won’t live in, up to 80% of a value below $1 million, so the minimum down payment stays at 20%. Insured purchases of a home you live in also require a price under $1.5 million. The rules for a second home you use yourself, such as a cottage, are different again; see the down payment on a second home.
How lenders qualify you
Federally regulated lenders apply the stress test to rental mortgages too. Lenders check that you could afford the payments at the greater of your contract rate plus 2% or 5.25%, a floor set by OSFI for uninsured mortgages and by the federal government's mortgage insurance rules (the Minister of Finance's Eligible Mortgage Loan Regulations) for insured ones. Your debt ratios then include the new mortgage, your existing mortgage and other debts. CMHC’s limits for insured mortgages are 39% for gross debt service and 44% for total debt service; lenders set their own limits for uninsured rental mortgages, often similar.
Rent helps, but lenders don’t count all of it. Some add a share of the rent to your income (add-back); others subtract a share from the property’s costs (offset). The method and the share vary by lender, and they need a signed lease or an appraiser’s market rent estimate. The details, with examples, are in how rental income affects mortgage qualification.
Rates
A rental mortgage is usually uninsured, and the Bank of Canada’s figures show the gap between the two kinds of new fixed-rate mortgages of 5 years or more: an average of 4.49% for uninsured loans against 4.05% for insured ones in July 2026. Some lenders add a further premium for non-owner-occupied properties, and alternative and private lenders charge more again. Compare offers from several lenders; current rates are tracked in the mortgage rates hub.
Financing a second property
If you already own a home, the questions are usually where the second down payment comes from and whether your debt ratios can carry two mortgages.
| Source or strategy | How it works | Trade-offs |
|---|---|---|
| Savings or non-registered investments | Pay the down payment in cash | Simplest; ties up capital |
| HELOC on your home | Borrow the down payment against your home’s equity | HELOC payment counts in your debt ratios; interest generally deductible when used for the rental |
| Refinance your home | Take a larger mortgage on your home and use the cash | May trigger a prepayment penalty mid-term; the extra borrowing is deductible when traced to the rental |
| Alternative or private lender | Looser qualification at a higher rate and fees | Useful short term; costly as a long-term structure |
| Vendor take-back | The seller lends part of the price, behind the bank’s mortgage | Needs a willing seller and, usually, the first lender’s consent; two payments |
| Joint venture | A partner contributes money or work for a share of the property | Needs a written agreement; see joint venture real estate |
If a HELOC supplies the down payment, lenders may still want to see that some of the down payment comes from your own resources. Using home equity to invest covers the HELOC and refinance routes in detail, including a worked example of a rental financed entirely with borrowed money.
Another route is to keep your current home as a rental and buy a new one. An owner-occupied mortgage may need to be converted to a rental product, so the lender needs to know. On the tax side: Turning your home into a rental is a deemed sale at fair market value, but you can elect under subsection 45(2) of the Income Tax Act not to be treated as having changed its use: you then can't claim capital cost allowance on it, you still report the net rental income, and you can keep designating it as your principal residence for up to four years (longer for some work relocations) as long as you designate no other home and stay resident in Canada. Converting a home to a rental covers the tax rules.
Growing a portfolio
Each additional mortgage makes the next one harder to get:
- The debt ratio squeeze. The new mortgage is counted at the stress-test rate while only part of the new rent is counted, so each purchase adds a gap that your employment income has to cover.
- Lender limits. Some lenders cap the number of financed properties per borrower or the total exposure to one borrower, and policies differ, so ask each lender. Investors who reach one lender’s limit may turn to credit unions, monoline lenders or alternative lenders.
- Commercial financing. Buildings of five units or more are qualified mainly on the property’s own income, using a debt service coverage ratio. CMHC’s multi-unit programs are covered in multi-family investing.
Strategies investors use as they scale:
| Strategy | How it works | Watch for |
|---|---|---|
| Recycling equity | Refinance or open a HELOC on a property that has risen in value to fund the next down payment | More debt on every property; less cushion if prices fall |
| Refinancing after renovation | Buy below value, renovate, then refinance at the new appraised value | Appraisal and seasoning risk; see the BRRRR strategy |
| Cross-collateralization or a blanket mortgage | One loan secured on several properties | A default on one puts all of them at risk; harder to sell one property |
| Private bridge, then refinance | Buy fast with a short private loan, stabilize the property, refinance with a regular lender | High cost if the refinance is delayed or the appraisal is low |
| Staggered terms | Spread renewal dates across different years | Avoids renewing every mortgage in the same high-rate year |
Ways to limit the risk include a cash reserve for each property, checking that every mortgage still works at a higher renewal rate, and hiring property management before the workload becomes unmanageable. Holding a larger portfolio in a company is covered in real estate investing in a corporation.
Tax and cash flow in brief
Interest on a rental mortgage is deductible against the rental income, but the principal part of each payment is not; see when mortgage interest is tax-deductible and how rental income is taxed. The gain on sale is a capital gain; see capital gains on rental property. Before applying, run the property through the rental property calculator: a newly bought rental with the minimum down payment may not cover its costs, as the worked example in using home equity to invest shows.
Buying through a mortgage broker who places investment mortgages gives access to lenders with different rental income and portfolio policies.
