- A mortgage broker shops multiple lenders on your behalf, compares rates and terms, and negotiates for you — instead of limiting you to a single institution.
- In Québec, the activity is regulated by the AMF (Autorité des marchés financiers). For a residential file, the broker is often compensated by the lender, meaning frequently no direct cost to the borrower — to be confirmed based on your file.
- From 1 to 4 units: residential-type financing. From 5 units and up: commercial financing analyzed by income (RCD/DSCR).
- CMHC and MLI Select programs can allow a reduced down payment and extended amortization, depending on current guidelines.
What does a mortgage broker do?
A mortgage broker is an intermediary between you and lenders. Rather than knocking on the door of a single bank, you entrust them with your project and they shop for financing from multiple sources: banks, credit unions, alternative lenders, and for larger files, commercial lenders. They build your file, compare rates and terms, and then negotiate on your behalf the conditions (rate, amortization, prepayment penalties, repayment flexibility).
For a multiplex project, their value lies primarily in their knowledge of lenders who finance this type of asset and in their ability to present the building's numbers in the right way. A broker specialized in income properties speaks the language of yield and knows which lender accepts which file profile.

How is the broker regulated, and how much does it cost?
In Québec, mortgage brokerage activity is regulated by the Autorité des marchés financiers (AMF). You can verify that a broker holds the right to practise; this is a basic reflex before sharing your financial documents.
On the compensation side, the most common model for a standard residential file is that the broker is paid by the selected lender. In that case, there is often no direct cost to the borrower. For more complex files — multiplex, commercial financing, private lenders, or atypical situations — fees may apply. The prudent rule: have the compensation structure confirmed in writing for your specific file before retaining anyone.
Residential (1–4) vs. commercial (5 units and up) financing
The most important distinction in income property financing comes down to the number of units:
| Your building | Financing logic |
|---|---|
| 1 to 4 units | Residential: the lender focuses primarily on your personal income and credit file. Rental income counts, but the analysis remains centred on the borrower. |
| 5 units and more | Commercial / multiplex: the lender first analyzes the building's ability to service its own debt, using the debt service coverage ratio (DSCR), net operating income (NOI), and normalized expenses. |
In practice, from 5 units up, the building is judged as much as you are. The debt service coverage ratio (RCD/DSCR) compares the building's net operating income (NOI) to the debt service: a lender generally wants revenues to comfortably cover payments. That is why a rigorous assessment of revenues and expenses is decisive — a point you can prepare with a chartered appraiser for income properties and calculate with our financing comparison tool.
The debt service coverage ratio (RCD/DSCR), explained
As soon as we talk about 5 units and up, one figure dominates the lender's analysis: the debt service coverage ratio, abbreviated RCD in French and DSCR (Debt Service Coverage Ratio) in English. It is the ratio between what the building generates and what it costs to repay.
The logic is straightforward: take the net operating income (NOI) (rents, minus normalized expenses such as taxes, insurance, utilities, maintenance, and a vacancy allowance), then divide by the annual debt service (principal and interest). The result indicates how many times the building covers its payments:
- A DSCR of 1.0 means the building just barely covers its payments — with no margin.
- A DSCR above 1.0 means it generates a surplus after debt service.
- A DSCR below 1.0 means the building does not service its own debt.
In practice, commercial lenders generally require a DSCR well above 1.0 to maintain a safety margin. The exact threshold depends on the lender, the type of building, and the program — and it can be lower under CMHC-insured financing than for conventional financing. Remember the principle rather than a specific figure: the more comfortable the DSCR, the easier the file is to finance, and the higher the amount you can borrow. This is also why well-documented expenses and realistic rents directly affect your borrowing capacity.
Note: the DSCR is only one of the levers. The lender also looks at the loan-to-value ratio, your down payment, the quality of the building, and your borrower profile. A good DSCR does not guarantee financing, but a poor DSCR almost always complicates it.
The CMHC MLI Select program, explained
MLI Select is one of the CMHC mortgage loan insurance programs that generates the most interest among multiplex investors. The core idea: in exchange for commitments on your part, the program can provide access to more favourable terms than conventional financing.

The commitments generally fall under three main categories: affordability (offering rents below certain thresholds), energy efficiency (meeting performance targets), and accessibility (making units accessible). The higher your commitments, the greater the potential benefits. In general terms, those benefits may include:
- A reduced down payment compared to conventional financing — freeing up capital for other projects.
- An extended amortization, spreading payments over a longer period and improving monthly cash flow.
- A more flexible required DSCR in certain cases, since the loan is insured.
It is precisely these levers — less capital tied up and better cash flow — that make MLI Select attractive for building or growing a portfolio. In return, the program requires a solid file and compliance with the commitments over time.
Important: the scoring tiers, affordability thresholds, and terms evolve. The figures presented here remain general: always refer to the current CMHC guidelines and have your eligibility validated by a broker or specialist before structuring your project.
CMHC and MLI Select: what are we talking about?
CMHC (Canada Mortgage and Housing Corporation) provides mortgage loan insurance. When a loan is insured, the lender's risk decreases, which can give the borrower access to better terms. For residential rental buildings, this insurance opens the door to financing that conventional lending does not always offer.
The MLI Select program targets buildings of 5 units and more. In exchange for commitments — for example around affordability, energy efficiency, or accessibility — it can provide access to benefits such as a reduced down payment and extended amortization. These two levers improve a project's cash flow, which explains investor interest.
Important: the scoring tiers, affordability thresholds, and MLI Select terms evolve. Always refer to the current CMHC guidelines and have your eligibility validated by a broker or specialist. For an overview, see our page on APH Select.
When to consult a mortgage broker?
Three situations come up most frequently:
- Buying a plex or multiplex: structuring financing before submitting an offer, and knowing what you can realistically get financed.
- Refinancing: a loan is coming up for renewal, you want to renegotiate the rate, consolidate debt, or adjust amortization.
- Pulling out equity: using accumulated value in a building to finance a new purchase, renovation, or another project.
In each case, the broker compares your current situation against the market and evaluates, based on your file, what is advantageous once fees are factored in.
What a broker needs to build your file
For a multiplex file, expect to provide documents that substantiate the actual income of the building:

- Current leases and the rent roll.
- Financial statements or a summary of revenues and expenses (taxes, insurance, utilities, maintenance).
- The borrower's income and credit file.
- Where applicable, documentation on the building's condition and planned improvements.
The cleaner and more normalized this data, the stronger the income-based analysis. A real estate tax accountant can help present clean financials, which makes it easier to obtain favourable terms.
Questions to ask your mortgage broker
Before retaining a broker for a multiplex project, a few targeted questions help you confirm they truly master this type of file — and avoid unpleasant surprises:
- Are you duly authorized to practise by the AMF? This is a basic reflex before sharing your financial documents.
- How many 5+ unit files have you handled? Commercial financing follows a different logic than residential.
- How are you compensated on my file? Get written confirmation of any fees and who pays them.
- Which lenders do you work with for multiplex properties? Banks, credit unions, commercial lenders, CMHC-insured lenders: the broader the panel, the more useful the shopping exercise.
- Do you have experience with CMHC and MLI Select? These files require specific preparation.
- What DSCR are you targeting and what down payment is realistic for my building? A precise answer shows they have already analyzed your situation.
- What are the fees, penalties, and prepayment conditions? The rate is only part of the total cost.
- What is the realistic timeline to funding? Useful if you have a purchase offer with deadlines.
Common financing mistakes
Many projects go off the rails not because of the market, but because of avoidable mistakes when structuring the financing. The most common:
- Thinking like a house. From 5 units up, the building is judged on its income (RCD/DSCR), not just your salary. Underestimating this shift in logic leads to refusals.
- Inflating revenues or understating expenses. A lender normalizes the figures. Unrealistic rents or overlooked expenses (vacancy, maintenance, management) weaken the DSCR and the file.
- Shopping with a single lender. Stopping at your bank means missing out on potentially much better terms elsewhere. That is exactly the value of a broker.
- Ignoring insured financing (CMHC / MLI Select). For a 5-unit-plus building, dismissing mortgage insurance upfront can mean missing out on a reduced down payment or extended amortization.
- Looking only at the rate. Penalties, repayment flexibility, renewal conditions, and fees sometimes weigh more heavily than a few basis points on the rate.
- Preparing your file at the last minute. Up-to-date leases, clean financials, and a complete file speed up the analysis and improve your terms.
- Forgetting transaction costs. Whether refinancing or buying, calculate the net benefit once fees are accounted for, not just the advertised rate.
