What salary to buy a duplex in Granby in 2026: the minimum household income for the owner-occupied median duplex, with the other unit's rent counted, next to the median house.
In Granby, the median duplex sells for $500,000. To buy it and live in it with the minimum down payment (about $35,870 in cash), you need a gross household income of about $79,800 a year, because the bank adds the other unit's rent ($1,520 a month, the city's median rent) to your income.

Rule: for an owner-occupied duplex, CMHC lets lenders add up to 100% of the other unit's gross rent to household income, and the property's taxes and heating may be left out of the calculation. Assumptions: Centris median prices of duplexes and single-family houses (January to September 2026); minimum down payment (5% of the first $500,000 and 10% of the rest) with the CMHC premium added to the loan; 25 years; stress test at the higher of 5.25% or the rate plus 2 points, i.e. 6.09% for a 4.09% rate; gross debt service (GDS) ratio of at most 39%; no other debts (car, cards, student loans); rent = median rent of Centris leases signed over 12 months in the city; house: taxes estimated at 1% of the price and heating at $1,200 a year counted.

How to read these numbers
Rule: for an owner-occupied duplex, CMHC lets lenders add up to 100% of the other unit's gross rent to household income, and the property's taxes and heating may be left out of the calculation (CMHC, Rental income page). Assumptions: Centris median prices of duplexes and single-family houses (January to September 2026); minimum down payment (5% of the first $500,000 and 10% of the rest) with the CMHC premium added to the loan; 25 years; stress test at the higher of 5.25% or the rate plus 2 points, i.e. 6.09% for a 4.09% rate; gross debt service (GDS) ratio of at most 39%; no other debts (car, cards, student loans); rent = median rent of Centris leases signed over 12 months in the city; house: taxes estimated at 1% of the price and heating at $1,200 a year counted. Each lender and each mortgage insurer (CMHC, Sagen, Canada Guaranty) applies its own rules: some count only 50% of the rent or require a signed lease. Have your file validated by a mortgage broker. Your other debts (car, cards, loans) reduce your capacity: the total debt service (TDS) ratio must not exceed 44%. Prices are medians, not a specific property.
