Quick Summary
Investment property interest rates are generally higher than rates on a primary residence, because lenders see rentals as riskier. To buy wisely, ask your lender exactly how they price the loan, compare fixed and variable options, and confirm the stress-test rate before you commit to a purchase price.
- Lenders usually charge more for rentals because borrowers may walk away from a rental sooner than their own home.
- In Canada, a rental buyer generally needs at least 20% down, since default insurance is generally unavailable for non-owner-occupied properties.
- Investment mortgages are stress-tested at a higher rate than your contract rate, so a rental may fail qualification.
- Fixed rates keep payments predictable, while variable rates can turn a marginal rental negative if rates rise.
- Calculate monthly cash flow including the mortgage, taxes, insurance, maintenance and management before making an offer.

Why Investment Property Interest Rates Run Higher
Investment property interest rates are generally higher than rates on a primary residence. Explore the Calgary luxury real estate investment opportunities that can make the financing worthwhile. Lenders often view a rental property as a greater risk, because a borrower may be more likely to walk away from a rental when money gets tight than from the home they live in. That risk can show up directly in the rate you are offered.
Lenders also look at where the income comes from. Rental income is usually counted less generously than employment income, and it can take months of tenant history before a lender gives it full weight.
Start by asking your lender exactly how they price investment property loans. Understanding where your rate will land is an important first step.
Investment Property Mortgage Requirements and Down Payments
Investment property financing usually requires a larger down payment than a home you will live in, and the size of that down payment directly affects the investment property interest rate you are offered. In Canada, a buyer purchasing a rental property generally needs at least 20% down, because mortgage default insurance is generally not available for non-owner-occupied properties (CMHC Income Property). Confirm the current requirements with your lender before making an offer.
Down payment tiers matter for pricing. Rate pricing often changes with the size of the down payment, so ask your lender to quote you at two or three down-payment levels to see the trade-off before you commit to a purchase price.
Qualification is where most investors get surprised. Lenders review your debt-to-income ratio and the property’s expected rental income, but they do not count rent the way you do. Lenders differ in how they count rental income, and the method used can meaningfully affect your borrowing power. Ask each lender how they calculate it.
Expect the stress test to apply. For investment properties, you must qualify at a rate higher than the one you actually pay, typically the greater of your contract rate plus a buffer or a published qualifying benchmark. A rental that cash-flows at your quoted rate may fail qualification once the stress-test rate is applied. Ask your lender for the exact qualifying rate they will use.
Some lenders, particularly in the alternative and private space, may qualify investment borrowers primarily on the property’s income rather than personal income. This is often measured with the debt-service coverage ratio (DSCR), which is net operating income divided by total debt service. Knowing whether your target lender is income-based or DSCR-based tells you which lever to pull: pay down the loan, raise rent, or choose a cheaper property.
Choosing Between a Fixed vs Variable Mortgage for Rental Property
A fixed-rate mortgage locks your interest rate for the full term, so your payment stays predictable and your investment property interest costs are easier to plan. A variable-rate mortgage tracks the lender’s prime rate, so your payment can rise or fall as rates move. For an investor, the decision is less about which rate is lower today and more about which structure survives a rate shock without breaking your cash flow.
Investors often prefer a fixed rate when cash flow is tight, because a variable-rate increase can turn a marginally positive rental into a negative one overnight. Variable rates can cost less when rates are falling or stable, but they carry more risk for a rental budget. Compare total cost over your intended holding period, not just the starting rate.
The stress test interacts with this choice in a way many investors miss. Because you qualify at a rate above your contract rate, a variable-rate application is often stress-tested at a higher qualifying rate than a fixed-rate application at the same starting rate. That can reduce your borrowing power on a variable product even though the variable rate looks cheaper. Ask each lender how they stress-test variable versus fixed investment mortgages.
Prepayment penalties are the other investor-specific factor, and they can add to the total cost if you exit early. Breaking a fixed term early can be expensive, and penalty structures differ between fixed and variable products. Review the penalty terms with your lender. If your strategy involves refinancing, selling, or repositioning within a few years, the penalty structure can matter more than the rate itself.
Map both options against your expected rental income and a higher interest scenario before deciding. If the variable payment still works under a rate increase, it may suit your plan. If not, the fixed rate is buying you certainty you actually need.
Running Your Numbers Before You Sign on the Dotted Line
Before committing, calculate the property’s monthly cash flow, including the investment property interest portion of your mortgage payment. Subtract the mortgage payment, property taxes, insurance, maintenance and property management costs from the expected rent. A positive result means the property pays for itself; a negative one means you are covering the gap from your own pocket.
Use a mortgage calculator to test your payment at different interest rates, and include closing costs, investment property interest charges and any hidden costs of ownership before you make an offer.

Before committing, compare the cost components that shape whether a rental pays for itself.
| Cost item | What to check | Why it matters |
|---|---|---|
| Mortgage payment | Test at different interest rates | Shows cash-flow sensitivity |
| Property taxes | Include in monthly costs | Reduces net rental cash flow |
| Insurance | Include in monthly costs | Reduces net rental cash flow |
| Maintenance | Budget ongoing repairs | Affects monthly margin |
| Property management | Include if you hire help | Reduces net rental cash flow |
| Closing costs | Add before making an offer | Adds to upfront investment |
| Cash flow | Rent minus all costs | Positive means self-funding |
Frequently Asked Questions
Are mortgage interest rates higher for investment properties?
Usually, yes. Lenders typically price rental property mortgages slightly above owner-occupied rates because they see a higher risk of default when a borrower may walk away from a rental before a home they live in. The gap varies by lender, term and borrower profile, so the only reliable way to know is to get written offers for both an owner-occupied and an investment scenario and compare them directly. Ask each lender to show the rate and the required down payment side by side.
How much down payment do I need to buy an investment property in Canada?
For a rental property, the down payment requirement is generally higher than for a home you live in. Confirm the current minimum down payment, mortgage default insurance eligibility and qualification requirements with your lender. Plan for closing costs on top of the down payment, and confirm the exact requirements with your lender before making an offer.
Should I choose a fixed or variable rate for an investment property?
A fixed rate gives predictable payments, which makes cash flow easier to forecast. A variable rate often starts lower and moves with the prime rate, so payments can rise or fall over the term. If your rental budget has little room for a payment increase, a fixed rate is the safer choice. If you have strong cash flow and can absorb changes, a variable rate may lower your borrowing cost. Stress-test any variable option at a higher rate before committing.
