    Down payment: owner-occupied or not

    Under CMHC rules, if you live in one unit, the minimum down payment is 5% on the first $500,000 and 10% on the rest for a 1- or 2-unit property, and 10% for a 3- or 4-unit property. For a 2- to 4-unit property you do not live in, CMHC requires at least 20%.

    If this is your first purchase and you live in one unit, the FHSA and Home Buyers' Plan (HBP) can be used: a unit in a duplex, triplex or fourplex can be a qualifying home (see our first-time buyer guide).

    $600,000 exampleMinimum down payment
    Duplex you live in$35,000
    Triplex or fourplex you live in$60,000
    2- to 4-unit plex you do not live in$120,000

    Using rental income to qualify

    For an owner-occupied plex, CMHC allows lenders to count rental income: up to 100% of gross rental income for a duplex, and up to 50% of gross income (or a net-income approach) for a triplex or fourplex. The stress test still applies: the higher of 5.25% or the negotiated rate plus 2%. Each lender has its own criteria.

    Buying a plex with tenants: TAL rules

    In Quebec, existing leases follow the property: when you buy a plex, you become the landlord of the tenants already in place, under the same conditions. Here are some Tribunal administratif du logement (TAL) rules to know before buying:

    Before making an offer, ask for the leases, rent history and property expenses.

    Welcome tax on a plex

    The welcome tax also applies to plexes. In Gatineau, it is $8,610.50 in 2026 for a $600,000 plex. If this is your first purchase and you live in one unit, you may qualify for Revenu Québec's home ownership access tax credit.
