What it really takes to buy your first duplex in Quebec

It is often the first question, and the most discouraging: "Do I really have enough money for this?" The good news is that the number in your head is almost always bigger than the real number. Here is how it works, without the jargon.

The number that changes everything: the down payment based on the number of units.

For a 2 to 4 unit building, the minimum down payment is 20% if you do not live there. But if you occupy one of the units, it can drop to as little as 5% on the first $500,000, and 10% on the excess. That is a difference of tens of thousands of dollars, and many first-time buyers do not know it before talking to us.

For a building of 5 units or more, you move into a completely different category: the financing becomes commercial, and the down payment, rate and amortization rules are different. It is not more complicated, but it is a separate calculation.

How commercial financing really works (5 units or more).

From 5 units, the building is no longer valued like a house: it is valued like a business, based on its income. This is called the income approach. The lender calculates the net operating income (rents minus operating expenses), applies a capitalization rate based on the area and building type, and it is that calculation, not the asking price, that determines the value used for financing.

Application fees also come into play. Most commercial lenders charge analysis fees to open and review a file, often structured as a base amount plus an additional amount per door (per unit). These fees vary a lot from one lender to another, and are sometimes added to the CMHC insurance premium if the loan is insured. The right reflex: always ask for this detail in writing before you commit. A mortgage broker who specializes in commercial can save you from surprises here.

Ancillary income matters more than you think. A paid laundry, parking spaces rented separately, wall air conditioners rented to tenants, or even an extra storage space: each of these incomes adds to the net operating income, and therefore to the value retained by the lender. Document them clearly, with proof of income if possible, before presenting your file.

Rented or owned water heaters: a detail that changes the picture. If the water heaters are rented (often from Hydro-Québec or a private supplier), the rental cost is a recurring expense that reduces the building’s net income, and therefore its financial value in the lender’s eyes. If you own the water heaters, that monthly expense disappears, but you must plan for their eventual replacement in your financial cushion. The lender wants to know which situation applies: it directly changes the numbers in your file.

What the bank really looks at (not just your salary).

A lender does not qualify you only on your employment income. It adds part of the building’s expected rental income to your file, often between 50% and 80% of the rent, depending on the institution. It is that calculation, more than your salary alone, that determines whether you qualify and for how much.

Your debt ratio (everything you owe each month, divided by everything you earn) must stay under a certain threshold. It is often that number, not the down payment, that blocks a first file.

Mistakes that waste time (and opportunities).

Shopping before being pre-approved. It leads to falling in love with a building you cannot finance, or worse, losing the building while you sort out the financing.

Forgetting closing costs. Notary, inspection, tax adjustments, insurance: budget 1.5% to 3% of the purchase price on top of the down payment.

Not shopping your financing. Conditions vary a lot from one lender to another for an income property. A mortgage broker who knows plexes can make a real difference on the rate and conditions.

What to remember.

The exact amount depends on your situation, but in the vast majority of cases, it is accessible faster than you think, especially with the right financing strategy. The first step is not to find the perfect building: it is to know exactly how much you can really afford.
