- The cap rate (capitalization rate) is the NOI ÷ value ratio: it is the key indicator for evaluating a plex's profitability independently of financing.
- On the North Shore in 2026, a cap rate above 5.5% is a good return; between 4% and 5.5%, it is in line with current market norms; below 4%, the return is low.
- An expense ratio above 50% should alert the owner: operating costs are eroding cash flow and reducing appeal to buyers.
- Improving your plex's profitability also improves its resale value — buyers purchase an income stream, not just walls.
What is a profitable plex in Québec?
A profitable plex is not simply a property where rents cover the mortgage. Profitability is measured independently of financing, based on the income the property generates relative to its operating expenses and its assigned value.
In Québec, a plex owner juggles two realities: on one side, rents — often below market on older leases — and on the other, operating expenses (property taxes, insurance, maintenance, management). Operating profitability is read through Net Operating Income (NOI), and the return on investment is expressed through the cap rate.
A plex is considered profitable when it generates a cap rate high enough to remunerate invested capital, service the debt, and leave a cushion for unexpected expenses. This threshold varies by property type, location, and market conditions — but on the North Shore, the standards are clear.

How to calculate income property profitability (NOI, cap rate, GRM)?
Three indicators are used to evaluate the profitability of a plex or multiplex:
1. Net Operating Income (NOI)
NOI is the foundation of everything. It is calculated by subtracting annual operating expenses from annual gross rental income. The mortgage is not included — NOI measures the property's performance independently of how it is financed.
NOI = Annual Gross Rental Income − Annual Operating Expenses
Example: $72,000 in income − $28,000 in expenses = $44,000 NOI.
2. Cap Rate (Capitalization Rate)
The cap rate relates the NOI to the property value. It is the gross return on the real estate asset without accounting for financial leverage. It allows two properties to be compared even if their prices are very different.
Cap Rate = (NOI ÷ Property Value) × 100
Example: $44,000 ÷ $880,000 × 100 = 5.0%
3. Gross Rent Multiplier (GRM)
The GRM is a quick indicator that compares the property price to gross income without accounting for expenses. It is useful for an initial filter but does not replace the cap rate. Our GRM calculator lets you compute it in seconds. For a deeper yield analysis, visit our complete guide on multiplex yield calculation.
GRM = Property Price ÷ Annual Gross Income
Example: $880,000 ÷ $72,000 = GRM of 12.2 (a lower GRM is better for the buyer).
| Indicator | What it measures | When to use it |
|---|---|---|
| NOI | Annual operating profit before debt | Gross cash flow, potential debt service |
| Cap Rate | Asset return (without leverage) | Compare properties, negotiate a price |
| GRM | Price / gross income ratio | Quick screening, first filter |
What cap rate to target on the North Shore in 2026?
Cap rate thresholds vary by market type, property size, and financing conditions. On the North Shore of Québec in 2026, market data allows us to define three zones:
These thresholds reflect the North Shore market conditions in 2026, where mortgage rates remain high and rental demand supports the value of well-positioned properties. A cap rate below 4% is common for properties with long-standing locked-in leases or in high-demand areas — current profitability is low, but appreciation potential is real.
A cap rate between 4% and 5.5% reflects the current market norm on the North Shore. Cash flow is limited but positive for a well-financed property. A cap rate above 5.5% indicates a high-performing property: market-rate rents, controlled expenses, strong competitive position.
To compare your property with recent transactions, our cap rate calculator includes updated sector benchmarks.
What to do if my plex isn't profitable enough?
A low cap rate isn't a verdict — it's a diagnosis that calls for targeted action. Here are the main levers for improvement:
- Bring rents to market rates: at lease renewal, you can adjust rents according to the Tribunal administratif du logement (TAL) guidelines. A single under-rented unit drags the entire cap rate down.
- Reduce the expense ratio: review your insurance policy, schedule maintenance work outside peak seasons, consolidate certain services if you own multiple properties.
- Optimize property management: tighter management (tenant screening, proactive renewals, minimal vacancies) improves NOI without touching rents.
- Invest selectively: a kitchen or bathroom renovation can justify a significant rent increase on a vacant unit. Our article what to do with an unprofitable plex in Québec in 2026 covers these strategies in detail.
- Consider selling: if no lever is sufficient to meet your goals, selling may be the best decision. Especially if the current market value allows you to realize an attractive capital gain. Read our guide on selling an income property without an agent in Québec.
Profitability vs. resale value: what's the connection?
Many plex owners pit these two concepts against each other — wrongly so. Profitability and resale value are closely linked, because income property buyers evaluate precisely by income. A property with a cap rate of 5.5% will sell at a better multiple than a similar property at 4%, all else being equal.
In practice, improving your NOI — whether by increasing income or reducing expenses — mechanically increases your property's market value if the market cap rate remains constant. This is what is called income-based valuation, the standard assessment method for any property with 5 units or more.
On the North Shore, well-maintained properties with market-rate rents sell faster and on better terms. Our guide on selling an income property without an agent explains how to make the most of this dynamic.
