Three readings. The plex gained 143% in ten years, less than the house (158%), because its price is held by rents and not by the buyer's emotion. Over five years, +34% for the plex against +46% for the house. It sells more slowly than the house (22 days against 13 days): the plex buyer runs the numbers before offering. In 2016, it took 77 days. The price fell in 2018, 2020, 2023 and 2026 (partial year), and the 2026 price remains below the 2025 peak ($700,000).

Financing a plex in Saint-Jérôme
- Owner-occupant of a duplex: insured loan, minimum down payment of 5% on the first $500,000 and 10% on the remainder, or $30,000 on the median duplex in Saint-Jérôme ($550,000); the second unit's rent counts in part toward your borrowing capacity.
- Owner-occupant of a triplex or quadruplex: 10% minimum, or $70,700 on the median triplex and $86,000 on the median quadruplex, insured loan possible under the $1.5 million cap.
- Non-occupant: 20% minimum, or $134,000 on the median plex and $110,000 on the duplex, and the lender only counts a fraction of the rents (often 50 to 80%) to qualify the loan.
- Five units and more: commercial loan, assessed on the building's net income rather than on your income.
- The costs: the welcome tax in Saint-Jérôme is calculated on the full price, and the inspection of an old building is worth its price. First-time buyer: the FHSA, the HBP and the Quebec credit apply to a plex you live in, see first-time home buyer in Saint-Jérôme.
What the median does not say
A plex is worth what its leases allow you to pay, and the Saint-Jérôme median says nothing about the leases of a particular building. At the median price, fully rented at market rent and financed at 80%, a plex rarely pays for itself in 2026: it is bought for the capital repaid by tenants, the appreciation and, often, the owner's own unit. Before offering, read the actual leases and their dates, the history at the Tribunal administratif du logement and the income proven by statements; the rents of leases signed in Saint-Jérôme are in rent in Saint-Jérôme. The checklist is in how to choose a good rental property and the owner's rules in the Quebec rental property owner's guide.
