Getting an investment property mortgage in Quebec doesn't follow the same rules as buying a home. The down payment runs from 5% to 20% depending on the property type and whether you live in it, and jumps to 15% of the economic value the moment you reach 5 units. More importantly, financing an investment property doesn't stop at the first purchase: it's leverage (the equity and rents from the properties you already own) that lets you add the next ones. This guide pulls together what the web scatters: the grid by type, how rents are treated, the 5-unit threshold, the 2026 programs and the mechanics of chaining purchases. First action: identify your case (owner-occupied or not, under 5 units or 5 and up), because that sets your down payment.
Key takeaways
- Down payment: owner-occupied duplex 5% · owner-occupied triplex or fourplex 10% · 1 to 4 units non-owner-occupied 20% · 5 units and up: 15% of the economic value.
- Rental income counts, but the lender keeps only about 50% of it (vacancy, management, repairs).
- At 5 units, you switch to commercial: qualification is based on the property's performance (DCR, economic value), not your personal ratios.
- 2026 programs: CMHC Standard, MLI Select (down payment as low as 5% and up to 50 years of amortization in exchange for commitments) and conventional.
- Stacking purchases = leverage: refinance a property (up to 80% of its value − the balance) or negotiate a vendor take-back to free up the next down payment.
"Investment property mortgage": one loan vs. the portfolio strategy
The phrase hides two very different things, which is where the confusion starts.
- The single loan. An investment property mortgage usually means the financing on one rental property: the loan you take to buy a duplex, a plex or a rental condo.
- The strategy (the "multi-loan"). This is holding several mortgages in parallel to finance several income properties, reusing the equity of each one. In French-speaking Quebec it's searched as "multi-prêt". Note that Multi-Prêts Hypothèques is also the name of the province's largest mortgage brokerage network, not a financing method. This guide is about the strategy.
In other words, a broker helps you get the financing; the multi-loan strategy describes how you chain it.
Action point: if your goal is to finance several properties, the strategy is what matters; a good broker still helps you execute it.
How much down payment for an investment property?
It comes down to two things: the number of units and whether you live in the property or not. Here is the 2026 minimum grid.
| Property type | Occupancy | Minimum down payment |
|---|---|---|
| Single-family / duplex | Owner-occupant | 5% (first $500,000; 10% on the portion above $500,000) |
| Triplex / fourplex | Owner-occupant | 10% |
| 1 to 4 units | Non-owner-occupied (rental) | 20% |
| 5 units and up | Either way | 15% of the economic value (≠ price paid) |
Three clarifications:
- Insured-mortgage cap. Mortgage insurance (CMHC, Sagen, Canada Guaranty) only exists for a property under $1.5M. Above that, it's 20% minimum (conventional). Insurance is mandatory whenever the down payment is under 20%, as the FCAC (Canada.ca) explains.
- Economic value, not price paid. From 5 units on, the 15% is calculated on the property's economic value (its income-earning capacity), often lower than the asking price. More on that below.
- The 2026 market reality. Even when the theoretical minimum is low, the down payment actually required on multi-unit deals often lands around ~40%: illiquidity, higher rates and lender caution (QC field research).
Action point: find your row in the table; that's your down-payment floor, not necessarily the final number. For the residential side, see also our guide on the down payment.
How rental income boosts your borrowing power
Good news: rents increase what you can borrow. Less good: the lender applies a haircut.
In practice, lenders recognize up to about 50% of the gross rental income (sometimes 70 to 80% depending on the lender and the program), as CMHC notes for rental properties. They do it two ways: either by reducing your housing costs (the offset method) or by adding that amount to your qualifying income. Either way, your ratios improve.
Why only half? To cover vacancy, management and repairs: a lender never bets on 100% of the rents.
The effect compounds: more recognized income today means more capacity for the next acquisition. That's what lets you keep buying.
Action point: confirm how YOUR lender treats the rents (offset or add-back) before you shop; it changes your borrowing capacity.
What changes at 5 units: personal vs. commercial
Five units is the dividing line. Below it, financing often works like a personal loan; from there up, the logic turns commercial.
- 2 to 4 units (and sometimes small 5- to 8-unit buildings). You can finance these personally: you qualify on your income, plus a share of the rents, through your debt ratios (MREX).
- 9 units and up. This is commercial financing. The bank looks first at the property's performance, not your salary, through the DCR, the debt coverage ratio: net operating income ÷ debt service (the annual loan payments, principal + interest) (MREX).
Commercial lending runs on one concept: economic value. Financing is based on the property's income capacity, and the lender takes the lowest of the price, the market value and the economic value. If the economic value comes in below the asking price, the gap comes out of your pocket as extra down payment.
Action point: from 5 units on, calculate your net operating income; that number, not your salary, decides the financing.
The 5 multi-unit financing programs in 2026
For 5 units and up, there are five main paths, from the most leverage to the most classic.
| Program | Down payment / LTV | Amortization | Min. DCR |
|---|---|---|---|
| CMHC Standard | 15% (LTV 85%) | up to 40 years | 1.10 |
| MLI Select 50 | from 15% + commitments | 40 years | 1.10 |
| MLI Select 70 | from 5% (LTV 95%) | 40–45 years | — |
| MLI Select 100 | from 5% (LTV 95%) | 50 years | — |
| Conventional | 25% (LTV 75%) | 25–30 years | 1.15–1.25 |
Table glossary: LTV = loan-to-value, the share of the price financed by the loan (the higher the LTV, the less you put in from your own pocket); DCR = debt coverage ratio (net operating income ÷ debt service).
The program to know is CMHC's MLI Select. It works on points (50, 70 or 100) awarded across three pillars: affordability, energy efficiency and accessibility (CMHC). The more points you earn by committing to those criteria, the more leverage you get: down payment as low as 5%, a loan-to-value of 95% and 50 years of amortization. A longer amortization lowers the monthly payment, so it improves cash flow and the DCR, which is often what makes a project viable.
Watch one cost: the CMHC insurance premium on multi-unit runs from 1.75% to 4.50% of the loan, added to the balance (QC field research). The exact thresholds vary by lender and by file.
Action point: if your project targets affordability or energy efficiency, ask a multi-unit broker to price MLI Select; our CMHC premium calculator estimates the insurance. The leverage can be substantial.
Financing multiple properties: leverage, refinancing and the vendor take-back
The secret to buying several income properties fits in one sentence: you don't buy the 2nd property with a 2nd salary, you buy it with the equity and income of the 1st. Here are the three levers, and the rule that governs them.
The golden rule of leverage. If the property's return beats the cost of the debt, borrowing makes you richer; if it's the other way around, borrowing makes you poorer (MREX).
- Refinancing (equity). You refinance a property you already own up to about 80% of its value, minus the balance owed. The difference comes out as cash and funds the next down payment (Scotia, RBC). A home equity line of credit does a comparable job without refinancing everything.
- The vendor take-back. The seller lends you part of the price, often in 2nd rank (a loan repaid after the bank's), at a rate of 0 to 5%. The result: the down payment you have to bring drops (MREX).
- Buy conventional, then refinance into CMHC. A common scaling play: buy fast on conventional terms, then switch to CMHC to stretch the amortization and free up equity (QC field research).
Guardrail: keep a cushion (vacancy, repairs, renewal at a higher rate) before adding a door. Over-leveraging without reserves is the number-one cause of a shortfall.
Action point + CTA: model the full scenario before you buy: refinancing the 1st, the down payment on the 2nd, the combined cash flow. Compare your multi-property scenarios in the mortgage calculator, then size the equity released with the refinance calculator.
Worked 2026 example: from fourplex to 6-plex
Let's follow one investor, step by step. (Illustrative figures, June 2026.)
Property 1: fourplex, owner-occupied
- Purchase price: $700,000. Owner-occupant down payment (2 to 4 units): 10% = $70,000. Loan: $630,000.
- The 3 other units rent for $1,250/month each = $3,750/month, i.e. $45,000/year in gross income.
- The lender recognizes 50%, i.e. $22,500/year added to your capacity.
~4 years later: refinance to buy the 2nd
- Estimated value of the fourplex: $790,000 (about +3%/year). Remaining mortgage balance: ≈ $570,000 (approximation at ~4% over 25 years).
- Refinance at 80%: $632,000. Equity released: $632,000 − $570,000 = $62,000.
Property 2: a 6-plex (commercial switch)
- Purchase price: $900,000. At 5 units and up, the down payment = 15% of the economic value.
- Estimated economic value: $850,000 → down payment = 15% × $850,000 = $127,500.
- Price − economic value gap to cover out of pocket: $900,000 − $850,000 = $50,000.
- Total cash required: $127,500 + $50,000 = $177,500.
- Where does it come from? Refinancing property 1 ($62,000) + a vendor take-back from the seller ($60,000) + savings ($55,500) = $177,500. The numbers add up.
Action point: redo this calculation with YOUR numbers before any offer; start by estimating each property's rental yield.
Common mistakes
- Confusing one investment property mortgage with the "multi-loan" strategy. One is a single loan, the other is a financing method for a portfolio (Quebec SERP).
- Believing 5% is enough for a rental. The 5% is for the owner-occupant of a duplex; a non-owner-occupied rental = 20%, and 5 units and up = 15% of the economic value (hypotheques.ca, nesto).
- Counting 100% of the rents. The lender keeps only about 50% (CMHC).
- Analyzing a 5+ unit building like a plex. At 5 units, the DCR and the economic value decide, not your personal ratios (MREX).
- Ignoring MLI Select. You can move from 25% down to 5%, and up to 50 years of amortization (CMHC).
- Over-leveraging with no cushion. A single empty unit can tip cash flow into the red (QC field research).
- Applying a French or American rule. In Quebec: down payment by type, CMHC, economic value and DCR; no "35% debt rule" or "28/36" (off-market search results).
Action point: before the offer, check three things: the right down-payment grid, rents counted at 50%, and a cushion planned.
In short, financing an investment property in Quebec depends on the property type and occupancy; rents count for half; everything switches to commercial at 5 units; and leverage funds the next ones. Compare your multi-property scenarios in the mortgage calculator before you submit an offer.
