The down payment, and what the lender accepts

- Owner-occupied triplex: 10% minimum, or $51,950 on the median triplex, $34,700 more than for the duplex; owner-occupied quadruplex: $68,500. Insured loan possible under the $1.5 million cap.
- Without living in it: 20% minimum ($69,000 on the duplex, $103,900 on the triplex), and the lender only counts a fraction of the rents.
- First-time buyer: the FHSA, the HBP and the Quebec credit refunding the welcome tax (up to $5,875, first home, since January 1, 2026) apply to a plex you live in.
Across the 23 cities tracked, the minimum down payment of the owner-occupied triplex exceeds that of the duplex in 23 cities: the 10% rule weighs more than the price gap. In median of cities, $25,000 for the duplex and $56,950 for the triplex. The mortgage insurance premium is added to the loan: to be costed with your mortgage broker.

How to read these figures
The price per unit divides the type's median by its number of units: it compares buildings of different sizes, not units of the same floor area, and a 1925 triplex does not have the units of a 2015 duplex. The gap with the house compares the type's median with the Sorel-Tracy single-family median over the same period. Down payments apply the 2026 mortgage insurers' rules to the medians: to be confirmed with your mortgage broker.
