Questions About Mortgage Basics

Practical answers on mortgage basics for Canadian real estate investors — financing, strategy, and next steps.

Mortgage Fundamentals

A fixed-rate mortgage keeps the same contract rate for the term, so the payment is predictable. A variable-rate mortgage moves with the lender’s prime rate, so the payment or the principal split can change. Investors often weigh payment stability against the chance of a lower rate if prime falls — the right choice depends on cash-flow tolerance and how long you expect to hold the loan.
Amortization is the number of years used to calculate the payment, not the length of the current term. A longer amortization lowers the monthly payment and can improve cash flow, while a shorter one builds equity faster. Canadian residential terms are commonly 1–5 years inside a longer amortization; commercial and CMHC multi-unit programs can allow longer amortizations than a typical house loan.

Investment Property Financing

Rental mortgages usually need a larger down payment, may price at a different rate, and often count only a portion of rent toward qualification. Lenders also review your overall portfolio, experience, and remaining debt capacity. Owner-occupied purchases follow different down-payment and insurance rules than a pure rental.
High-ratio insured mortgages are mainly for owner-occupied homes that meet insurer rules, not for typical investor rentals. Most investment purchases are conventional (uninsured) and need more equity. Multi-unit buildings with five or more units may instead use CMHC multi-unit insurance, which is a different product from a residential high-ratio policy.

Working With Lenders

A bank can only offer its own products. A broker can compare multiple lenders, which matters when one institution declines an investor, self-employed, or portfolio file. Shopping the structure often surfaces a workable path that a single-bank conversation would miss.
Start with the property type, down payment, and whether you will occupy a unit, then compare residential, conventional, and commercial options. Book a free LendCity™ strategy call if you want a broker to map lenders and next steps for your file.

Mortgage Fundamentals (Continued)

Federally regulated lenders generally qualify uninsured and many insured residential mortgages at the higher of the contract rate plus two percentage points or the OSFI benchmark qualifying rate. That test reduces maximum borrowing power compared with the actual payment. Rules and exceptions can differ for insured products, credit unions, and commercial files, so confirm the test that applies to your deal.
