Since January 1, 2026, the federal bank regulator’s capital rules classify a mortgage as income-producing residential real estate, or IPRRE, when repayment depends mainly on the property’s own cash flow. The working test is simple: if more than half of the income used to qualify the mortgage comes from rent, the loan is IPRRE and the bank has to hold more capital against it. Nothing in the rule changes how you qualify. What it changes is how expensive that file is for the bank, and banks pass expense on as rate, conditions or a polite no. Here is how the test works, who trips it and how to stay on the cheap side of the line.
What actually changed, and what did not
OSFI’s Capital Adequacy Requirements guideline for 2026 took effect on January 1, 2026 for most federally regulated banks. OSFI has been clear that the IPRRE expectation itself dates from 2023 and that the 2026 update is about capital, not about the underwriting rules in Guideline B-20. So the stress test is unchanged, rental income can still be used to qualify, and there is no new cap on how many properties you can own. Industry summaries of the guideline put the risk weight on an IPRRE mortgage at roughly 45% against about 30% for an owner-occupied mortgage at the same loan-to-value, which is the reason a bank cares which side of the line your file falls on.
The 50% test, with real household numbers
Take the income a lender uses to qualify you and split it into salary and rent. If rent is more than half, the mortgage is IPRRE. A Kelowna nurse earning $95,000 with one condo renting for $2,400 a month is at 23%. A two-income household at $140,000 with two rentals bringing in $4,800 a month is at 29%. A retiree on $75,000 with three suites at $6,000 a month total is at 49%, one rent increase from the line. A part-time earner on $60,000 with four doors at $7,500 a month is at 60% and every new mortgage in that portfolio is IPRRE.
What it means when you are on the wrong side
Three things show up in practice. First, price: some banks add a premium to the rate on IPRRE files, or simply stop offering their sharpest promotional rates on them. Second, appetite: a few lenders have tightened how many rental doors they will carry for one borrower, or how much of a portfolio can be IPRRE. Third, treatment of the rent itself: a bank that previously used a generous offset may fall back to a 50% add-back on files it classifies as income-producing, which changes the qualification math a lot more than a few basis points of rate. The investment property mortgages in Kelowna page walks through the add-back and offset methods; the rental income calculator shows both on your numbers.
Staying under the line without giving up the portfolio
The test is a ratio, so both sides move it. On the income side, a co-borrower’s salary, a documented bonus or the two-year average of self-employed income all count. On the rent side, lenders that use an offset method do not add the rent to income at all, which can keep an investor with several doors out of IPRRE at that lender while the same file is IPRRE at a bank that adds rent back. Not every lender is federally regulated either: BC credit unions sit under the provincial regulator and follow their own capital rules, so a file that is expensive at a bank can be ordinary at a credit union. This is lender selection again, and it is exactly why investors with three or more properties tend to end up with a broker.
Who should care right now
If you own one or two rentals and have a salary, you are almost certainly under 50% and nothing changes for you. If you are building past three doors, if your income is mostly rent, or if you are retired and living on rental income, the classification decides which lenders want your next file. Have it mapped before you write an offer, not after. The landlord renewal guide covers the timing on an existing portfolio.
Frequently asked questions
Does the OSFI rule stop me from getting a rental property mortgage?
No. The 2026 rules are capital rules for banks, not qualification rules for borrowers. Rental income still counts, the stress test is unchanged and there is no federal cap on the number of properties. What changes is the cost to the bank of a file where more than half the qualifying income is rent, which some lenders pass on as rate or tighter terms.
What is IPRRE?
Income-producing residential real estate. In OSFI’s framework a residential mortgage is IPRRE when repayment depends materially on the property’s cash flow, which in practice means more than 50% of the income used to qualify comes from rent.
Do BC credit unions follow the same rule?
BC credit unions are provincially regulated and set their capital treatment under BC rules, so the federal IPRRE classification does not apply to them in the same way. That is one reason a portfolio investor’s next file may fit better at a credit union than at a bank.
How do I know which side of the 50% line my file is on?
Add up the income the lender will use (salary, documented bonus, two-year self-employed average) and the rent the lender will count, then divide rent by the total. Under 50% is a standard file. The calculator in this series shows the numbers under both rental-income methods.
