Three readings. The plex gained 81% in ten years, less than the house (92%), because its price is held by rents and not by the buyer's emotion. Over five years, +56% for the plex against +55% for the house. It sells more slowly than the house (6 days against 5 days): the plex buyer runs the numbers before offering. In 2016, it took 64 days. The price fell in 2017 and 2018, and the 2026 price is the highest of the series.
Duplex, triplex or quadruplex: the price of the door
| Type (Quebec City, Jan. to Sept. 2026) | Median price | Price per unit | Sales | Since 2016 | Since 2021 |

| Quadruplex | $725,000 | $181,250 | 61 | +87% | +53% |

Financing a plex in Quebec City
- Owner-occupant of a duplex: insured loan, minimum down payment of 5% on the first $500,000 and 10% on the remainder, or $29,300 on the median duplex in Quebec City ($543,000); the second unit's rent counts in part toward your borrowing capacity.
- Owner-occupant of a triplex or quadruplex: 10% minimum, or $63,516 on the median triplex and $72,500 on the median quadruplex, insured loan possible under the $1.5 million cap.
- Non-occupant: 20% minimum, or $120,000 on the median plex and $108,600 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 Quebec City 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 Quebec City.
What the median does not say
A plex is worth what its leases allow you to pay, and the Quebec City 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 Quebec City are in rent in Quebec City. The checklist is in how to choose a good rental property and the owner's rules in the Quebec rental property owner's guide.
How to read these figures
Days on market is the number of days between listing and the accepted offer, in median. The sold-to-asking ratio compares the sale price with the last listed price: below 100%, the buyer negotiated. Down payments are calculated on the Quebec City medians with the mortgage insurers' rules in force in 2026, to be confirmed with your mortgage broker; the insurance premium is added to the loan.
