OSFI clarified that the same borrower income cannot be re-used to classify multiple mortgages as General Residential Real Estate (GRRE) for capital purposes — additional mortgages where repayment materially depends on rental income must be classified as Income-Producing Residential Real Estate (IPRRE), which triggers higher lender capital requirements. CRITICAL: this is a capital classification rule, NOT an underwriting rule. B-20 is unchanged — lenders can still use rental income to qualify you across multiple properties. But the capital cost of the loan is higher, which can translate into higher rates or stricter terms on investor properties.
OSFI's clarification (communicated September 11, 2025, restated and emphasized November 14, 2025) tightens how lenders classify mortgages for CAPITAL purposes — not how they qualify borrowers. The distinction matters because it changes the economics of mortgages on second-and-beyond rental properties, even when you personally still qualify under B-20.
The Two Classifications
| Classification | Trigger | Capital Cost |
|---|
| GRRE (General Residential Real Estate) | Repayment does NOT materially depend on property cash flows. Owner-occupied, or rental where the borrower's other income comfortably services the debt. | Lower |
| IPRRE (Income-Producing Residential Real Estate) | Repayment IS materially dependent on the property's rental income. In-place since 2023 — not new. | Higher (more capital reserved per dollar lent) |
The New Rule (the part the November clarification nails down)
A mortgage can be classified as GRRE only if:
- The borrower's income used to support that classification has NOT already been used to classify another mortgage as GRRE, AND
- Income from other residential real estate properties is NOT considered when classifying as GRRE.
Plain English: you can't "reuse" your salary to make multiple mortgages look like GRRE for capital purposes, and you can't lean on income from your other rentals to dodge the IPRRE classification on a new one.
What This Means in Practice
For investors with 1 property:
Likely no change. Your primary mortgage classifies as GRRE; if you buy a rental, the rental's mortgage gets evaluated on its own merits.
For investors with 2+ properties:
The SECOND, THIRD, etc. mortgages on rentals are much more likely to be classified IPRRE for capital purposes — even if you qualify under B-20 using rental offsets. Lenders carrying these as IPRRE on their books face higher capital requirements, which they pass through as:
- Higher rates on investor mortgages
- Stricter down-payment requirements (some lenders moving to 25%+ on investor properties)
- Tighter LTV caps
- Stricter qualifying ratios
What did NOT change:
- B-20 underwriting is unchanged. Lenders can still apply rental income to qualify you across multiple properties.
- Stress test rules are unchanged.
- The IPRRE classification itself has been in place since 2023 — only the clarification on income re-use is new.
Why OSFI Issued the Clarification
When the Capital Adequacy Requirements 2026 Guideline (effective January 2026) was finalized, the industry asked whether the rules changed for rental properties. OSFI's answer: "The CAR update was not about rental properties and there were no changes to the expectations for IPRRE that have been in place since 2023." The November clarification re-states the existing rule because lenders were interpreting it inconsistently.
Your Next Steps
- If you own 2+ rental properties: ask your lender how they're classifying your existing mortgages and what that means at renewal
- Before adding another rental: get pre-approval that explicitly flags whether the new mortgage will be GRRE or IPRRE, and what rate/terms apply
- Stay current on B-20 underwriting — that's still your qualifying gate, regardless of capital classification
