If you’ve invested in a duplex or a 6-plex before, a 50-unit building can feel like a monster. The price tag alone can make your stomach turn. But the truth is, with the right analysis, these deals become surprisingly logical. In this blog, we’ll break it down step by step, showing how rental income, operating expenses, and financing costs affect the overall investment.
Buying a larger apartment building in Calgary is not just about the purchase price. You also need to understand its income potential, vacancy risks, and ongoing expenses to see whether the numbers make sense. With a clear financial picture, you can make more informed investment decisions and avoid costly surprises.
Scenario: A 50-Unit in NE Calgary
You come across this listing:
- Price: $8.2 million
- Avg. Monthly Rent: $1,200
- Other Income: $20,000/year
- Vacancy Rate (projected): 5%
- Expenses (estimated): 42% of income
Let’s see if it’s a good deal.
1. Start with Potential Income
Gross Rental Income = 50 × $1,200 × 12 = $720,000/year
+ Other Income = $740,000
Now subtract 5% for vacancy and non-payment:
Effective Gross Income = $703,000
2. Estimate Operating Expenses
At 42% of income:
Expenses = 0.42 × $703,000 = $295,260
3. Net Operating Income (NOI)
NOI = $703,000 – $295,260 = $407,740
That’s your profit before debt payments. This is the number lenders care about.
4. Let’s Talk Cap Rate
Cap Rate = $407,740 ÷ $8,200,000 = 4.97%
Pretty solid in today’s market, Calgary has cap rates around 4.5% to 5.5%, so this is a fair market deal.
5. What About Cash Flow?
Assume 25% down ($2.05M), and finance $6.15M at 5.25%, 30-year term:
Debt Service (annual): approx. $410,000
Now calculate:
Cash Flow = NOI – Debt Service = $407,740 – $410,000 = –$2,260
You’re close to break-even. A small rent increase ($50/unit) could push you into positive territory.
6. Debt Coverage Ratio
DCR = $407,740 ÷ $410,000 = 0.99
Banks won’t love that. But with CMHC-insured financing (MLI Select), your payments could be $90K–$100K lower annually. That flips this deal into strong positive cash flow.

Frequently Asked Questions (FAQs)
To analyze a 50-unit apartment building, calculate its potential rental income, vacancy losses, operating expenses, net operating income (NOI), cap rate, financing costs, and cash flow. These figures help determine whether the property is a suitable investment.
Net operating income is calculated by subtracting operating expenses from effective gross income. Effective gross income accounts for vacancy and other income adjustments. NOI does not include mortgage payments or income taxes.
Cash flow depends on rental income, vacancy rates, operating expenses, maintenance costs, financing terms, and mortgage payments. Careful budgeting and effective property management can help investors maintain more predictable cash flow.
Professional property management helps coordinate rent collection, tenant communication, maintenance, lease administration, and financial reporting. These services can reduce the daily workload for owners and support the long-term performance of their investment.
CMHC MLI Select may offer eligible multi-unit residential property owners access to favourable financing terms based on qualifying criteria. Lower financing costs or longer amortization periods, where available, may improve cash flow and make a 50-unit apartment investment more financially manageable.
