Qualifying for a mortgage these days is tough, especially with high home prices, higher interest rates, and the need to pass a mortgage stress test. Given that, any bit of help to qualify for a mortgage goes a long way. If you have rental income, you can add it to your mortgage application to help nudge your lender in your favour, and you may be able to use that extra income to increase your chances of getting approved. Whether you are weighing buying versus renting or taking on a landlord mortgage for a rental, here is what you need to know about using rental income to qualify for a mortgage in Canada.
Key Points
1. If you already own a rental property, lenders can count a portion of your existing rental income, commonly 50% to 80%, toward the income they use to qualify you.
2. You can also use future (projected) rental income on a property you have not rented yet, but lenders base it on a market rent letter from an appraiser, not on a number you choose.
3. How the income is applied depends on whether the property is owner-occupied, whether it is the subject of your loan application, and how many units it has.
4. Rental income lowers your GDS and TDS ratios, which can help you qualify, sometimes for a larger mortgage.
Can You Use Your Rental Income To Get A Mortgage?
Yes. Not only does rental income help cover your mortgage payments, but it can also increase your ability to get approved for a home loan. On top of that, you may be able to secure a larger mortgage amount with the help of this added source of income.
Income is one of the key factors that lenders look at when reviewing mortgage applications. In addition to traditional income sources, they will look at other forms of income, including money coming in from rent. If you already have a property that you rent out and receive consistent rental income, it can be added to your mortgage application.
Demand for rental units is strong, too. About one-third (33.1%) of Canadian households rent their home rather than own it2, and the average rent for a two-bedroom apartment reached $1,550 in 20251.
Future Rental Income
Rental income comes in two forms when you apply for a mortgage, and lenders treat them a little differently.
Existing rental income is rent you already collect on a property you own. Because it is established, lenders are comfortable counting a portion of it, and you back it up with a signed lease and your tax returns (Form T776).
Future rental income is the rent you expect to earn on a property you have not rented yet. This is common when you are buying a rental property, or a home with a basement suite you plan to rent out. You can still use it to qualify, but lenders base the figure on a market rent letter, an appraiser’s estimate of fair market rent, rather than a number you choose. Some lenders are more conservative with projected rent, so it may carry a little less weight than income you already collect.
| Factor | Existing Rental Income | Future (Projected) Rental Income |
|---|---|---|
| What it is | Rent you already collect on a property you own | Expected rent on a property you have not rented yet, or a unit you plan to rent out |
| How you prove it | A signed lease plus your tax returns (Form T776) | A market rent letter, an appraiser’s opinion of fair market rent |
| How lenders treat it | Well established, so a portion is readily counted | Accepted, though some lenders are more cautious with rent not yet collected |
| Best for | Existing landlords and already-tenanted units | Buyers of a rental property, or a home with a suite they plan to rent |
One thing to keep in mind is that this is about rental income, not future resale value. Lenders qualify you on income you can document, whether you already collect it or an appraiser estimates it, not on the profit you hope to make when you eventually sell. Anticipated appreciation does not count toward qualifying.
How Much Of Your Rental Income Can Be Used When Applying For A Mortgage?
Even though the CMHC’s rules state that all of your rental income may be used when you apply for a mortgage, your lender will likely only use a portion of the rent when calculating your total income.
The amount of rental income that lenders will consider varies considerably, though it could be anywhere from 50% to 80% on average. Even so, any amount of income counted can help boost your odds of mortgage approval.
Rental Offset Vs Rental Add-Back
Lenders apply your rent in one of two ways, and the method affects how much it helps your application:
- Rental offset: a share of the rent, often 50% to 80%, is subtracted from the property’s carrying costs, which lowers your GDS ratio.
- Rental add-back: a share of the gross rent, commonly around 80%, is added to your qualifying income, which lowers both your GDS and TDS ratios.
The add-back method is usually the more generous of the two. Traditional banks and default-insured mortgages generally use the offset method, in line with mortgage insurer guidelines, while many alternative lenders, such as B-lenders and some credit unions, prefer add-back, which can give your rent more weight. Some lenders also look at a debt coverage ratio (DCR), which measures the property’s income against its costs, and often want to see a DCR of about 1.1 or higher.
Note: You Will Need Proof Of The Rent
You may be required to have a lease showing how much rent you are charging. Or, you may need a market rent letter, which is a real estate appraiser’s opinion of how much the unit could rent for in today’s market. A market rent letter is what makes future rental income usable when there is no tenant in place yet.
For rent you already collect, a lender may also want to see bank statements showing the deposits, along with your tax returns (T1 General and Form T776).
How It Works
Rental income helps you qualify by boosting the income side of your debt service ratios, the two measures (GDS and TDS) that lenders use to decide whether you can afford the mortgage. The more qualifying income you have, the lower those ratios, and the more room you have to borrow. How much of your rent counts comes down to three questions: is the property owner-occupied, is it the subject of your loan application, and how many units does it have? The diagram below shows how those answers route you to one of four CMHC approaches.
Note: You Can Still Use Rental Income To Qualify
In a November 2025 clarification, Canada’s banking regulator (OSFI) confirmed that federally regulated lenders can continue to use rental income to qualify borrowers, including investors who own several properties4. Recent changes to how lenders classify these mortgages for capital purposes do not change how your rental income is used to qualify you.
Owner-Occupied Rental Properties
The Canada Mortgage and Housing Corporation (CMHC) allows homeowners who rent out part of their home to use 50% to 100% of their rental income as an income source when calculating their debt service ratios. To be eligible for the full amount, the following criteria must be met:
- You must live on the property that you are renting out.
- The rental unit must be self-contained with a separate entrance and meet zoning requirements.
- The property can only have a maximum of 2 units.
The percentage of gross rent is added to your gross annual income, so the GDS and TDS ratios would be calculated as follows:
- GDS Ratio: annual principal and interest / (gross annual income + 50% to 100% of gross rental income)
- TDS Ratio: (annual principal and interest + other debts) / (gross annual income + 50% to 100% of gross rental income)
For example, say your gross annual income is $60,000 and your housing costs add up to $20,000 per year. If the annual rent collected is $18,000 and 50% of the rental income may be considered, the formula would look like this:
$20,000 / ($60,000 + $9,000) = 0.2899, or 28.99%
A GDS ratio of 28.99% falls under the 39% maximum threshold, which should be satisfactory in the eyes of the lender.
Non-Owner-Occupied Rental Properties
For non-owner-occupied rental properties (2 to 4 units), up to 50% of gross rental income can be added to your total gross annual income. Taxes and heat may be excluded from your debt service ratio calculation. To calculate your TDS ratio, follow this formula:
TDS Ratio: (annual principal + interest + taxes + heat) / (gross annual income + net rental income)
How To Get A Mortgage Using Future Rental Income
If the property you are buying is not rented yet, you can still put its expected rent to work on your application. Here is how to get a mortgage using future rental income.
Order A Market Rent Letter
Ask an appraiser for a market rent letter, their opinion of fair market rent for the unit. This is what lets a lender count rent when there is no tenant in place yet.
Gather Your Supporting Documents
Have your purchase agreement ready, along with any signed lease if a tenant is lined up, and details of any suite you plan to rent out.
Confirm Your Down Payment
A home you will live in can qualify with a smaller down payment, but a non-owner-occupied rental property needs at least 20% down.
Ask How The Lender Treats The Rent
Confirm which approach the lender uses, up to 50% of gross rent or the net rental income method, and how much of your projected rent will count.
Pass The Stress Test
Your application, including the projected rent, still has to pass the mortgage stress test at the qualifying rate.
Compare Lenders
Lenders weigh projected rent differently, so it pays to compare a few to see who gives your future rental income the most credit.
What If You Already Own A Rental Property?
If you already own a rental property and want to buy another, you can use the rental income from the property you own to help qualify for the new mortgage. This is common when you are buying a second home and renting out the first. Because that income is established, lenders verify it with your signed lease and your tax returns (Form T776), then apply a portion of it toward your debt service ratios on the new purchase.
For a property you do not live in, lenders usually lean on the net rental income approach, gross rent minus operating expenses, and factor in the principal, interest, taxes, and heat on the rental you already own. If the rental runs at a loss, that shortfall is treated as a debt, so a property with healthy, well-documented rent helps your application the most. If you have built up equity in the property you own, you may also look into whether you can get a second mortgage on a rental property to help fund the next purchase.
Secondary Suite Incentive Programs Across Canada
One of the most practical ways to create rental income is to add a secondary suite, such as a basement apartment or a backyard unit, to a home you own. That extra unit can generate rent that helps you qualify for financing down the road. Most provinces offer a tailored secondary suite incentive program to make it easier for homeowners to create or improve rental spaces, and you can find the full breakdown in our guide to the secondary suite incentive program.
| Program | Financial Support |
|---|---|
| Calgary, Alberta Secondary Suite Incentive Program | Receive up to $10,000 |
| Hamilton, Ontario Ontario Renovates Secondary Suite Forgivable Loan Program | Forgivable loan of up to $50,000 |
| British Columbia Secondary Suite Incentive Program | Forgivable loan of up to 50% of renovation costs, to a maximum of $40,000 |
| Newfoundland and Labrador Secondary Basement Suite Incentive Program | Forgivable loan of up to 50% of renovation costs, to a maximum of $40,000 |
| Nova Scotia Secondary and Backyard Suite Incentive Program | Forgivable loan of up to 50% of renovation costs, to a maximum of $40,000 |
Program details and eligibility change over time, so confirm the current terms with your province or municipality before you budget for a suite.
Common Mistakes To Avoid When Using Rental Income
A few missteps can weaken an otherwise strong application. Watch out for these:
- Relying on cash rent with no paper trail. Lenders want a signed lease and matching bank deposits, not an informal arrangement.
- Assuming 100% of the rent always counts. Most lenders use 50% to 80%, and only specific owner-occupied cases reach 100%.
- Treating all lenders the same. Banks and alternative lenders use different methods, so the same rent can help more with one lender than another.
- Counting rent from an unpermitted unit. The suite usually has to be legal, self-contained, and meet zoning rules.
- Overstating projected rent. For a unit that is not rented yet, the figure has to come from a market rent letter, not your own estimate.
- Submitting documents late. Missing paperwork is one of the most common reasons an application stalls.
Final Thoughts
Several key factors affect your ability to get a mortgage, and income is one of them. You can increase your total income by using rental income to qualify for a mortgage in Canada, whether that income is already coming in or is projected through a market rent letter. As long as all other factors are favourable in the eyes of the lender, you may even be able to secure a higher loan amount, and perhaps a lower interest rate too.
