What You Should Know About Buying A Home With a Rental Suite

Sabeena Bubber • June 4, 2019

Thinking about buying a home with a rental suite? This can be a great idea if you want to help offset the cost of your home expenses, and it can also potentially help with qualifying for a mortgage on your new purchase, but there are some things you should know up front.

  • Most lenders will allow you to add 50% of the rental income back to your income for qualifying; however, there are a few that will consider up to 100% given the strength of your overall mortgage application.
  • Adding the rental income back to your income for qualifying shouldn't be confused with doing a rental income offset. 
  • You can expect a rental suite to increase your maximum mortgage amount by roughly $50k.
  • Although it doesn't have to be a "legal" suite, there should be a separate entrance along with a kitchen and bathroom in the unit.
  • Income from a roommate is not allowed by insurers as rental income to be used in mortgage qualification.
  • Lenders may require a signed lease agreement as confirmation of the rental income, and most prefer to see the agreement set to a year. This means you either need to speak to the existing tenant or have a potential tenant in place before qualifying for the mortgage.
  • Some lenders may consider a statement of economic rents (from a property appraiser) in lieu of a lease agreement.
  • Most lenders will not accept rental income from a family member.

Suffice to say, if you plan on purchasing a property with a rental suite and you need the rental income offset to qualify for the mortgage, you should make sure you've been pre-approved ahead of time and you've worked the numbers.

Why the Source of Your Down Payment Matters More Than You Think When buying a home, most people focus on how much they need for a down payment. What often gets overlooked is that where the down payment comes from matters just as much to the lender . The source of your down payment affects approval, risk assessment, and how your mortgage is structured. Here’s why lenders care—and what you need to know. 1. Anti–Money Laundering Requirements Lenders aren’t just being cautious—they’re legally required to verify the source of your down payment. To comply with anti–money laundering regulations, lenders must document where every dollar of the down payment came from on every purchase. Acceptable Down Payment Sources Down payments can come from: Your own savings or investments Borrowed funds through an insured program (such as FlexDown) A gift from an immediate family member How You Prove the Source Personal savings: You’ll need bank statements showing the funds have been in your account for at least 90 days , or proof they were accumulated through payroll deposits or other acceptable sources. Borrowed funds: Any borrowed portion must be included in your debt service ratios , since you’re responsible for repayment. Gifted funds: A signed gift letter is required confirming the money is a true gift with no repayment obligation , along with proof the funds were deposited into your account. 2. Financial Suitability and Risk The source of your down payment also tells the lender a lot about your financial habits. Down payments coming from your own savings demonstrate: Positive cash flow The ability to save consistently Strong financial management This reassures lenders that you’re more likely to keep up with mortgage payments. If the down payment is borrowed or gifted, lenders may look more closely at the rest of your application to ensure the mortgage remains affordable. Why a Larger Down Payment Helps From a lender’s perspective, more equity equals lower risk. The more money you have invested in the property, the less likely you are to walk away from the mortgage. This reduces the lender’s exposure and can sometimes result in better terms. 3. Down Payment and Loan-to-Value (LTV) Your down payment directly establishes your loan-to-value ratio (LTV)—the percentage of the property’s value being financed. In Canada: Lenders can finance up to 95% of a property’s value The buyer must contribute at least 5% as a down payment Example: On a $400,000 purchase: Maximum mortgage = $380,000 Minimum down payment = $20,000 How the Source Affects LTV Property value must be genuine and independently supported. Lenders rely on appraisals and comparable sales—not artificial price inflation. If: The seller provides money back The buyer doesn’t bring the full down payment independently Funds move “behind the scenes” …the lender considers this a change to the LTV and may decline the mortgage. All financial details of the purchase must be fully disclosed. Non-disclosure is mortgage fraud , and lenders will not proceed if the numbers don’t align. Final Thoughts Lenders ask for detailed documentation about your down payment source for good reason—it affects legality, risk, and the structure of your mortgage. Understanding these rules upfront helps avoid delays, declined applications, and last-minute surprises.
