The 2026 Rental Lending Change for Investors: What OSFI Actually Did
OSFI's 2026 capital rules change how lenders classify rental properties as income-producing residential real estate. What changed, who is affected and the cost.
In its Capital Adequacy Requirements for fiscal 2026, OSFI created a new category, income-producing residential real estate (IPRRE), for residential mortgages where more than 50% of the borrower's qualifying income comes from rental income, and required that the same rental income not be counted for more than one mortgage. Banks must hold more capital against IPRRE loans. OSFI said in November 2025 that this is a capital rule, not an underwriting change: Guideline B-20's qualifying rules, the stress test and debt-service limits are unchanged. In practice, lenders have priced IPRRE files higher (often 0.25% to 0.75% more), lowered maximum loan-to-value on some, and tightened documentation of which rent supports which mortgage. A salaried borrower with one or two rentals is unaffected.
Figures come from the CostToClose rental cash flow calculator.
What changed and what did not
| Metric | Before 2026 | From 2026 |
|---|---|---|
| Qualifying rules (B-20) | Contract + 2% stress test; GDS/TDS limits | Unchanged |
| How much rent counts | Lender policy: 50–80% add-back or offset | Unchanged |
| Capital the bank holds | Standard residential mortgage weighting | Higher weighting when > 50% of qualifying income is rent |
| Counting the same rent twice | Common in portfolio lending | Prohibited |
| Effect on the borrower | — | Higher rate or lower LTV on IPRRE files; more documentation |

Who crosses the line
The test is the share of qualifying income (the income the lender uses) that is rental. Two examples:
| Borrower | Employment income | Rent counted | Rent share | Classification |
|---|---|---|---|---|
| Teacher with a basement suite | $95,000 | $10,800 (50% of $1,800/mo) | 10% | Standard |
| Investor with four rentals, part-time job | $40,000 | $67,200 (80% offset on $7,000/mo) | 63% | IPRRE |
The investor is approved on the same ratios as before; the mortgage simply costs more.
What lenders have done
- Priced IPRRE files at a premium, ranging from a quarter to three-quarters of a point in published broker rate sheets.
- Required a rent roll and leases matched to each existing mortgage, so the same unit's rent cannot support two loans.
- In some cases capped loan-to-value at 65% to 75% for borrowers whose income is mainly rent.
- Credit unions, which are provincially regulated and not bound by OSFI's capital rules, have become the relative beneficiaries for portfolio investors.
What it means for a new purchase
Compute your rent share before you apply. If you are near 50%, adding one more property can tip every future mortgage into IPRRE pricing, including renewals. Options: hold the new property with a co-borrower whose employment income lowers the share; use a credit union; or accept the premium and price it into the cash-flow analysis.

Frequently asked questions
Did OSFI change mortgage qualifying rules for rental income in 2026?
No. The stress test and debt-service limits are unchanged. OSFI changed how much capital banks hold against mortgages where most of the borrower's income is rent, which lenders have passed on as higher pricing.
What is IPRRE?
Income-producing residential real estate: OSFI's 2026 capital category for residential mortgages where more than 50% of the borrower's qualifying income comes from rent.
Can I still use rental income to qualify?
Yes, under each lender's existing 50% to 80% add-back or offset policies. The same rent cannot be used for two mortgages.
Are credit unions affected?
Not by OSFI's rules; they are provincially regulated. Many still apply similar tests, but pricing on portfolio investors has been more stable there.
Does this affect my existing mortgages?
Not until renewal, when the lender re-prices under the current classification.
