How Lenders Count Rental Income

This is the part of the plan most likely to be wrong in your head, and the one that decides which homes you can actually make an offer on.

The short answer

Lenders do not add suite rent to your income pound for pound. They count a portion, and how much varies by lender, by whether the suite is legal, and by your wider file. It is a conversation about a specific property, not a rule you can look up.

Why it is not a simple addition

Lenders are underwriting the risk that the rent stops. They discount it accordingly, and different lenders discount it differently, which is why two brokers can give you two different maximum prices for the same household.

Some approaches add a portion of the rent to income. Others subtract a portion from the expense side. The arithmetic differs and so does the outcome.

What changes the answer

Whether the suite is legal is the big one. A permitted, inspected unit is treated more favourably than one that is not, and some lenders will not count an unauthorized suite at all.

Documentation matters too. An existing tenancy with a written agreement and a payment history is stronger evidence than a projection.

  • Whether the suite is legal, which some lenders treat as a threshold question
  • Whether there is an existing tenancy agreement and rent history
  • The lender's own policy, which varies more than most buyers expect
  • Your overall file, since this interacts with everything else in it

What to do about it

Get a pre-approval that reflects the property type you are actually pursuing, and tell your broker you are looking at homes with suites so the question surfaces before you are in a subject period.

If the plan only works with rental income counted, confirm the specific treatment before you write an offer rather than after.

Common questions

Do lenders add suite rent to my income?

Not pound for pound. They count a portion, and the method and the amount vary by lender. Some add a share to income, others offset a share against the expense side, and the resulting maximum price differs.

Will a lender count rent from an unauthorized suite?

Some will not count it at all, and others will count less of it. This is one of the main practical consequences of the legal versus unauthorized distinction, and it is worth establishing before you rely on the income.

What should I ask my broker?

How much of the rent this specific lender will count on this specific property, whether the suite's legal status changes that, and what documentation they need. Get it before you write an offer.
