The Interest-Only Mortgage

Katherine Martin • December 22, 2020

Relatively self-explanatory, an interest-only mortgage is one where your entire mortgage payment goes to interest and does not pay down the principal mortgage amount at all. So at the end of your term, you will owe the same amount as when you got your mortgage.

So you might be asking yourself, what are the advantages? Well, an interest-only mortgage frees up your cash flow. As you’re not responsible for paying down the principal balance, you can expect a lower mortgage payment. The interest-only mortgage shines as a management tool for rental properties, where cash-flow is king.

Here’s an example. On a $400k mortgage balance, over 25 years, at a 4% interest rate, the monthly repayment on an amortized mortgage would be roughly $1902/mth. However, as an interest-only mortgage, the payment is $1,321/mth, providing you with an extra $580 in monthly cash flow.

The money you save by not paying down the principal of your mortgage can be used however you like. It could be used to pay off higher interest debts like credit cards, unsecured line of credits, or any other high-interest loans. Or it could be used to offset the increased cost of maintaining your home through retirement; property taxes certainly aren’t going down anytime soon. It could even be used to maintain your current lifestyle if you’re planning retirement.

Regardless of what you decide to do with the extra cash, the choice is yours. If you would like to discuss the option of an interest-only mortgage (or any other mortgage product for that matter), please contact me anytime!

Why the Property Matters When You’re Qualifying for a Mortgage When qualifying for a mortgage, lenders typically look at four core areas: Income Credit Down payment or equity The property itself Most buyers focus heavily on income, credit, and savings—and for good reason. But even if those boxes are checked, the property can still determine whether a mortgage is approved. Why Lenders Care About the Property From a lender’s perspective, the property is the collateral for the mortgage. In the unlikely event of default, they need to know the home can be sold quickly and at fair market value to recover their funds. Because of this, lenders are careful about the condition, value, and marketability of any property they finance. Homes that are in poor repair, unconventional, or overpriced can raise red flags—even when the borrower is well qualified. Appraisals Are Always Part of the Process Every mortgage requires an appraisal to confirm value. Insured mortgages (through CMHC, Sagen, or Canada Guaranty) often use an automated valuation model completed online. Conventional mortgages typically require a full, on-site appraisal by a certified appraiser. This appraisal is not optional and happens after an offer is accepted—not at the pre-approval stage. Why Pre-Approvals Aren’t a Guarantee A pre-approval is a great first step, but it only assesses you, not the property. Once you’ve made an offer, the lender must approve the specific home you’re buying. Understanding this upfront helps avoid surprises and confusion later in the process. The Risk of Buying Without a Financing Condition In competitive markets, buyers sometimes remove financing conditions to strengthen their offer. However, this comes with risk. If the appraisal comes back low—or the lender is concerned about the property’s condition—you could be denied financing after the offer is firm. In that scenario, your deposit may be at risk. Buying a Home That Needs Work If you’re considering a property that isn’t in perfect condition, there are solutions. A purchase plus improvements program allows you to buy a home and include renovation costs in your mortgage. The process is structured and requires planning, but it can be an excellent way to turn a fixer-upper into a great long-term investment. Final Thoughts Mortgage approval isn’t based solely on your finances—the property matters just as much. Knowing this ahead of time helps you make smarter offers, reduce risk, and plan more effectively.
