A Canadian landlord might collect $2,700 in rent, pay property tax, insurance, condo fees, and repairs from one account, then use salary or business income to cover the mortgage on the family home. Month after month, the routine looks normal. The rent pays for the rental. The paycheque pays for the house.
At MortgageFree Canada, Zac Lofeudo’s team starts with that trail. They look at the family home, rental-property debt, rent deposits and expense payments in the same file, rather than treating each mortgage as its own isolated product.
“Everyone wants the rate first,” Zac says. “I get why. It is the number people know. But on a landlord file, the rate is not enough. Show me where the rent lands, what pays the repairs and which debt is actually going down.”
Under rental cash damming, the landlord sends rent toward the primary home mortgage and borrows separately to pay eligible rental expenses. Zac recommends making additional repayments on the home loan, whose interest generally cannot be deducted. Interest on borrowing for rental purposes can be deductible, provided the transactions are traceable. The arrangement changes where the rent goes, rather than creating new income.
The Tax Issue Is the Use of the Money
The tax issue comes back to how borrowed money is used. The Canada Revenue Agency’s interest deductibility guidance says interest deductibility depends on whether borrowed money is used for the purpose of earning income from a business or property. The facts matter, and so does the trail.
Paying off a rental mortgage does not preserve its deduction for later borrowing. New funds spent on the owner’s home remain personal debt. Interest may be deductible when the money finances another qualifying investment or eligible rental expenses, with records showing its use.
“Before I talk products, I want to know if someone could explain the file to an accountant two years from now,” Zac says. “If they cannot, we slow down.”
The review starts with ordinary records: current mortgage balances, renewal dates, rental income, recurring expenses, bank accounts, and how repairs are paid. From there, a borrower can see whether the portfolio supports the strategy or whether the existing setup needs to be left alone.
The Work Starts in the Accounts
Bria Ambler, client success manager with MortgageFree Canada, says the first stage is often less dramatic than landlords expect. Many files begin with basic questions about accounts and payments.
“A lot of people know the rent number and the mortgage payment,” Bria says. “They do not always know where every repair came out of, or whether the rental account is actually separate. Once that is visible, the numbers are easier to talk about.”
The $2,700 rent does not increase when a landlord pays extra toward the rental mortgage. Those payments put more capital into the property and reduce leverage. Zac would direct the additional cash toward the home loan while it remains outstanding, with a separate allowance for vacancies and repairs.
The strategy will not fit every borrower. Short-term rentals can raise different tax and usage questions. Some borrowers do not have the equity or the right lending product. Others have records that need to be cleaned up before a planner or accountant would be comfortable with the approach.
What Rate Shopping Misses
Higher borrowing costs have made landlords more alert to every renewal notice and rate quote. Zac says those conversations still matter, but they rarely answer the full question for a household with both a primary home mortgage and a rental property.
“A lower rate helps, of course,” Zac says. “But if the rent is sitting in the wrong lane every month, the rate is only one part of the file.”
Zac considers a 30-year rental amortization, where approved, to leave more rent available for the primary home mortgage. The bank must support those transfers.
“You want to lower the monthly payments on a rental property as much as possible,” Zac says.
“Where we can extend the rental to 30 years, I want that lower payment,” Zac says. “Keep the leverage in the rental and put the extra cash toward your primary home mortgage, rather than making additional rental payments.”
