Five Mortgage Renewal Questions for Canadian Landlords

For landlords, a mortgage renewal sets more than the next payment. It shapes how much cash remains available for repairs, which debt can be paid down faster and what it could cost to sell or move before the term ends. Those choices matter when rental properties sit alongside a mortgage on the family home.

CMHC’s 2026 Mortgage Consumer Survey found that 35% of renewers faced higher payments, with an average increase of $375 a month. Zac Lofeudo, who leads MortgageFree Canada, says owners should look past the offered rate and consider how the contract fits their plans for each property. He warns that selling partway through a term can carry a substantial penalty.

1. How much cash will remain after the mortgage payment?

Rent can cover a mortgage payment on paper and still leave little room for an empty unit, a repair or other property costs. When the required payment consumes most of the rent, owners may have to draw on their salary to keep the property running. Renewal is a chance to check whether the payment leaves a workable monthly cushion.

Where the lender allows it and the borrower qualifies, Lofeudo favours resetting a rental mortgage to a 30-year amortization. A longer amortization can lower the required payment, leaving more cash available for property costs or for extra payments on the mortgage used to buy the family home.

The choice also reflects how interest is treated. Interest on borrowing used to buy or improve a rental can be deductible under CRA rules. Lofeudo therefore prioritizes extra payments on the family-home mortgage, whose interest is generally not deductible, rather than accelerating rental principal repayment. Paying down rental principal still reduces debt and increases the owner’s capital tied up in that property, so the trade-off is between lower leverage and the use of available cash.

2. How would a major repair be financed?

Property equity does not automatically provide ready cash. A landlord planning to finance repairs through a home equity line of credit needs to confirm the approved limit, how much credit is actually available and what it would cost to carry a balance.

The Financial Consumer Agency of Canada distinguishes between a HELOC combined with a mortgage and a standalone HELOC. In a combined arrangement, available credit can grow as the mortgage principal is repaid; a standalone HELOC has a set limit. Interest-only payments leave the borrowed amount outstanding, and most HELOCs have variable rates, so borrowing costs can change.

Tax treatment depends on what the borrowed money pays for. “Paying off the rental mortgage does not mean you can borrow it back with the same deduction,” Lofeudo says. “If the new money pays down your home or covers personal spending, that interest is not deductible. It depends on what the new borrowing funds.” Owners considering this route need to understand both the borrowing terms and the use of the funds.

3. Could a sale or move happen before the term ends?

A landlord might expect to hold a rental for years but move from the family home sooner. The two mortgages may therefore call for different terms. Matching their renewal dates can be convenient, but it does not ensure that each contract fits the owner’s likely timeline.

A portable mortgage may be transferred to another home, subject to the lender’s conditions. Anyone expecting to move should check those conditions and understand the cost of ending the mortgage early. Breaking a contract can trigger a prepayment penalty.

Lofeudo includes that potential cost when weighing mortgage offers. A lower rate may deliver less value if the owner expects to sell before the term expires and the penalty is large. The relevant comparison depends on the expected time in the property as well as the rate and payment.

4. Do the prepayment terms fit the repayment plan?

Owners who plan to use extra cash to pay down the family-home mortgage need to check the contract’s prepayment privileges. Lenders can set limits on payment increases and lump-sum payments; exceeding those limits can trigger a penalty. The allowed amounts and timing need to line up with the owner’s intended transfers.

This can be especially relevant for a landlord considering rental cash damming: directing rental income toward additional payments on the home mortgage while arranging borrowing for eligible rental expenses. MortgageFree Canada says it compares the planned transfers with the lender’s payment schedule and prepayment limits, and reviews whether the credit arrangement can cover the rental costs. Restrictions on either side can affect whether the proposed arrangement works as intended.

5. Is the current lender still the best fit?

Renewal does not oblige a borrower to stay with the existing lender. Switching requires approval from a new lender and may involve appraisal, registration or other fees. The Financial Consumer Agency of Canada recommends shopping a few months before the current term ends, leaving time to compare offers and negotiate.

Lofeudo says the comparison should include switching costs and the features an owner would gain or give up, alongside existing debts and plans for the properties. If fees absorb much of the expected savings, renewing with the current lender may still make sense. “There is time to negotiate when renewal is still a few months away,” he says. “Once the deadline is close, people are trying to get it finished. That is a difficult time to start comparing lenders.”

The practical takeaway is to assess each mortgage against the property it supports and the owner’s likely next steps. Cash flow, repair financing, mobility, prepayment room and lender costs all shape the renewal decision; the rate alone can’t capture those trade-offs.
