Rent or buy · Sainte-Thérèse · 2026
The median rent of the past twelve months in Sainte-Thérèse, against the monthly cost of the median 2026 condo: mortgage with the minimum or 20% down, condo fees, interest and principal shares, and what the same rent would buy. Centris leases and sales, the rate actually charged, nothing estimated.
In Sainte-Thérèse, the median rent of the 33 leases signed on Centris from September 16, 2025 to September 16, 2026 is $1,700 a month (half between $1,450 and $2,000). Buying the median 2026 condo ($372,500, 114 sales) costs $2,234 a month with the minimum down payment ($18,625, 5.0%), the 5-year rate charged in 2026 (4.14%) and the median condo fees in Sainte-Thérèse ($270): $534 more than the rent, 131% of it. But $705 of that payment is principal repaid in the first year; the owner's sunk cost, interest and fees, is $1,529 a month, $171 less than the rent. With 20% down ($74,500), the monthly cost drops to $1,860 a month, still $160 above the rent. It is one of the places where buying comes closest to renting among the 50 units tracked (median gap $728). Sources: Centris, Bank of Canada, compiled October 8, 2026.

In Sainte-Thérèse, the gap between renting and buying is small, and it closes further if the buyer has more than the minimum down: at 20%, only $160 of gap remains. For a tenant who has the down payment, it is the kind of market where waiting is expensive: rent leaves, principal stays. For a condo seller, it is a market where buyers come straight from the neighbourhood's tenants, an argument for the listing: "your rent pays for this condo". Rent by unit size is in average rent in Sainte-Thérèse; the detail of fees, in condo fees in Sainte-Thérèse.
Three Centris sources, one period. Rents: leases signed in Sainte-Thérèse through a broker over twelve months, in median. Prices: condos sold in 2026. Fees: the median monthly condo fees of condos sold in the past twelve months. The sunk cost separates, within the payment, interest (lost like rent) from principal (saved in the condo), at the 2026 rate and over the first year; the principal share rises every year. What the table leaves out falls on the owner: taxes, insurance, maintenance, the return the down payment would have earned elsewhere, buying and selling costs. The calculation with a specific household's rate and down payment is done in a meeting.
$2,234 a month for the median condo of $372,500 with the minimum down ($18,625) and condo fees, against a median rent of $1,700: $534 more a month, of which $705 is principal repaid.
In cash flow, yes, by $534 a month with the minimum down. In sunk cost, no: interest and fees come to $1,529, $171 less than the rent. The owner pays more each month but keeps part of it.
