For the median house in Rosemère ($845,000, minimum down payment of $59,500), a 30-year amortization lowers the payment from $4,337 to $3,934 a month, or $403 less, and brings the required income down from $186,913 to $175,965.

Assumptions: Centris median price (January to September 2026) of single-family houses and condos; minimum down payment (5% up to $500,000, 10% on the portion above, 20% above $1.5M); CMHC premium added to the loan (2026 schedule, + 0.20 point over 30 years); insured 5-year fixed rate of 4.09% kept for the whole term (a scenario, not a forecast), compounded semi-annually; minimum income at the stress test rate (6.09%) with property taxes at 1% of the price and $1,200 a year of heating, 39% debt ratio.

Who qualifies for 30 years?
Since December 15, 2024, an insured mortgage (down payment under 20%) can be amortized over 30 years for all first-time buyers, whatever the property, and for any purchase of a newly built home. CMHC then adds 0.20 percentage point to the insurance premium (for example, 4.00% becomes 4.20%). With 20% down or more, the loan is not insured and a 30-year amortization depends on the lender.
What it changes for buying in Rosemère
In Rosemère, 30 years frees up more money each month than in most of the 50 cities tracked, because prices are higher. For a first-time buyer, it is often the difference between buying this year and renting longer. Now is the time: the choice is there, and the prepayment privileges most lenders allow let you shorten the term later. For the cash to plan for: the cash for a house in Rosemère.
How to read these numbers
Assumptions: Centris median price (January to September 2026) of single-family houses and condos; minimum down payment (5% up to $500,000, 10% on the portion above, 20% above $1.5M); CMHC premium added to the loan (2026 schedule, + 0.20 point over 30 years); insured 5-year fixed rate of 4.09% kept for the whole term (a scenario, not a forecast), compounded semi-annually; minimum income at the stress test rate (6.09%) with property taxes at 1% of the price and $1,200 a year of heating, 39% debt ratio. Total interest is a constant-rate scenario with no prepayment: in practice, the rate changes at every renewal and every extra payment narrows the gap. The welcome tax, notary and other cash costs are the same in both cases.
