What is the NIM (Net Income Multiplier)?
The NIM (Net Income Multiplier) is a financial ratio used to evaluate the value of an income property based on its capacity to generate profit after deducting operating expenses. Unlike the GRM, which ignores management costs, the NIM offers a transparent view of net performance. The lower the NIM, the higher the yield potential relative to the purchase price.
Basic formula
NIM = Sale Price ÷ Net Operating Income (NOI)
NOI = Effective Gross Income − Operating Expenses (taxes, insurance, maintenance, management, utilities). Always exclude debt service.

How to calculate the NIM — Step by step
NOI is calculated from net income after normalized operating expenses.
Step 1 — Calculate the NOI
NOI = Effective Gross Income − Normalized Operating Expenses
Include: property taxes, insurance, maintenance, management fees (min. 5%), common area electricity, water, snow removal, capital reserve (1–2%). Exclude debt service.
Step 2 — Calculate the NIM
NIM = Sale Price ÷ NOI
Inverse of cap rate: NIM 18 = cap rate 5.56% | NIM 20 = cap rate 5.0% | NIM 16.7 = cap rate 6%

Annual gross income$165,000
Normalized operating expenses$60,000
Calculated NOI$105,000

By optimizing expenses (smart thermostats: −$5,000/year), new NOI = $110,000, new value = $1,760,000. You have just created $80,000 in equity value.
The 3 critical errors to avoid
01
Using actual expenses instead of normalized expenses
Financial institutions use normalized ratios. Do not rely solely on the current owner's invoices — an owner may underreport their costs.
02
Forgetting the vacancy rate
A building that is 100% occupied today may have 5% vacancy tomorrow. Always include a provision of 3% to 5% when calculating net income.
03
Ignoring upcoming municipal reassessments
A reassessment can reduce your NOI within months. Anticipate projected tax increases before finalizing your analysis.
Frequently asked questions about the NIM
The NIM (Net Income Multiplier) is a ratio that evaluates the value of an income property by dividing its price by the Net Operating Income (NOI). It is more accurate than the GRM because it accounts for operating expenses and reflects the true performance of the asset.
The GRM uses gross income (before expenses) — fast but less accurate. The NIM uses net income (after operating expenses) — more accurate and reflects management quality. The GRM serves as an initial filter; the NIM validates true profitability.
Low NIM (12–15): often associated with higher risk or secondary markets, but excellent cash flow. High NIM (18–22+): typical of premium markets (Plateau Mont-Royal, downtown) where long-term appreciation is prioritized. Suburbs (Laval, Longueuil): 16–19. North Shore: 15–18.
The conversion is direct: cap rate (%) = 1 ÷ NIM × 100. Examples: NIM 18 = cap rate 5.56% | NIM 20 = cap rate 5.0% | NIM 16.7 = cap rate 6.0%. The two indicators are the inverse of each other and measure the same reality from two different angles.
By increasing the NOI — either by raising income (below-market rents, ancillary revenue) or reducing expenses (energy optimization, better insurance contracts). Every additional dollar of NOI is multiplied by the area's NIM to create equity value.
No. NOI always excludes debt service (mortgage payments) and personal income taxes. This allows you to compare properties independently of their financing structure. To measure profitability after financing, calculate the return on equity separately.
You divide the purchase price by the annual Net Operating Income (NOI). A NIM of 15 means the price paid is equivalent to 15 times the building's annual net income.
Because it accounts for expenses. Two buildings with the same GRM can have very different NIMs depending on their actual costs (taxes, utilities, management, maintenance).
It depends on the sector and building size, but a lower NIM is generally more advantageous for the buyer. Always compare properties within the same local market.
No. It is an excellent initial filter, but also validate cash flow, cap rate, and the debt service coverage ratio (DSCR) before making an offer.
