The limits are tighter
Rental refinances are uninsured, so the cap is typically seventy-five to eighty percent of value, and pricing runs slightly above owner-occupied rates. The property must appraise well, the rent must document cleanly, and your personal income still has to carry the combined picture.
How the rent counts
Lenders use fifty to one hundred percent of documented rent, depending on the lender and whether a lease or market rent appraisal supports it. Declared rental income on your tax returns strengthens everything, which is why the investors who report properly refinance more easily than those who minimized taxes.
- Current lease or market rent appraisal
- Two years of tax returns showing the income
- Expense documents for the ratios
The tax advantage of borrowing against a rental
Interest on money borrowed against a rental property, used to invest further, is generally deductible. Interest tracing rules matter: keep the new funds cleanly separated and documented as invested, and have your accountant structure it. Done right, the refinance both funds growth and lowers the tax bill on the rents.
The portfolio flywheel
The classic Toronto strategy: buy, add value or wait for appreciation, refinance out the down payment, repeat. It works, but each turn of the wheel increases leverage and interest cost across the portfolio. Stress-test the whole picture at higher rates and lower rents before each new layer, because the flywheel spins both directions.
Frequently asked questions
- How soon can I refinance after buying a rental?
- Technically any time, but appraisals rarely support meaningful equity in the first year unless you renovated. Most lenders also season title for six to twelve months.
- Can I refinance a property held in a corporation?
- Yes, though fewer lenders serve corporate borrowers and pricing is higher. Personal guarantees are standard.
- Is there a limit to how many mortgages I can have?
- Each lender caps how many properties they will finance for one borrower, and ratios tighten with each property. Portfolio lenders and alternative products exist for larger investors.
