Which mortgage suits a rental property: shorter term, longer amortization or a HELOC? (Canada)

In Canada, the mortgage that suits a rental depends on whether the rent must cover the costs from the first month and how long you expect to hold the property. A longer amortization lowers the payment and costs more interest, a shorter term keeps your options open if you might sell or refinance, and a HELOC gives flexible borrowing that the lender can review. Whether the interest on any of them is tax-deductible is a question for your accountant, and we don't forecast what the property will be worth.

Two questions that sort most rental mortgages

Two questions sort most rental mortgages:

1. Does the rent need to cover the payment now? If the property has to carry itself month to month, the size of the payment matters most.
2. How long will you hold it, and might you sell or refinance before the term ends? If the plan might change, the cost of breaking the mortgage matters most.

This page covers only the mortgage side: payments, interest, balance and penalties. Whether the property is a good investment depends on returns and values we don't forecast. Investment value is a question for your financial advisor.

A longer amortization lowers the payment and adds interest

The amortization is the number of years it would take to pay the mortgage off completely. A longer amortization lowers the payment, which helps monthly cash flow and can help the coverage check lenders run on rentals. The trade-off: you pay interest for longer and the balance falls more slowly. On an uninsured rental, the amortization offered is the lender's own choice, subject to lender approval.

A worked example (principal only). Illustrative, not a quote. On a $480,000 mortgage, the principal alone averages $1,600 a month over 25 years ($480,000 ÷ 300 months). Over 30 years it averages about $1,333 ($480,000 ÷ 360), a gap of about $267 a month. Interest is added to both.

Once interest is included, the gap in the actual payment is somewhat smaller. The 30-year mortgage also carries a larger balance at every point and pays interest for five more years.

A shorter term keeps options open if the plan may change

The term is the length of your contract, often shorter than the amortization. Breaking a fixed term early usually costs the higher of three months' interest or the interest rate differential (source: Financial Consumer Agency of Canada, checked October 2026). On a variable-rate mortgage the penalty is commonly three months' interest; your contract governs.

When a term ends, there is no prepayment penalty: you can renew, switch or pay off. For a rental you might sell, or refinance to fund the next purchase, a term no longer than your expected hold limits that exposure. The trade-off is renewing more often, and the payment can change at each renewal. The detail is in should a rental investor choose a shorter term.

A HELOC is flexible, and the lender can review it

A HELOC (home equity line of credit) is a revolving line secured on a property you own. With a federally regulated lender, the revolving portion can reach 65% of the property's value, and the mortgage and HELOC together 80% (source: Office of the Superintendent of Financial Institutions, checked October 2026).

Many HELOCs allow interest-only payments, which helps the month but doesn't reduce the balance (the risks of interest-only HELOC payments). HELOC rates are usually variable, and a HELOC is generally a demand loan: the lender can review or reduce the limit.

Investors often use a HELOC on their home for a rental's down payment (HELOC for a rental down payment). Some lenders combine a mortgage and a HELOC in one readvanceable mortgage.

Matching the mortgage to the rental plan

• The rent must carry the property now: the payment comes first. A longer amortization lowers the payment; interest-only HELOC payments lower the payment further while the balance stays where it is.
• A long hold: interest over the whole hold and each renewal count most. A shorter amortization costs more each month and pays the balance down faster.
• You may sell or refinance within a few years: penalty exposure counts most. A term that ends before you expect to move, or a variable rate with its commonly smaller penalty, keeps the exposure down.

The total-cost-of-holding tool puts two of these side by side over your own hold. The tool shows payments, interest, the balance at the end and the penalty if the hold is shorter than the term.
