The down payment, and what the lender accepts
- Owner-occupied duplex: insured loan, minimum down payment of 5% up to $500,000 and 10% on the remainder, or $44,000 (6.4%) at the median price in Mirabel; the second unit's rent counts in part toward your borrowing capacity.
- Owner-occupied triplex: 10% minimum, or $97,500 on the median triplex, $53,500 more than for the duplex. Insured loan possible under the $1.5 million cap.
- Without living in it: 20% minimum ($138,000 on the duplex, $195,000 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.
