Buying a 50-unit apartment building in Calgary might sound like something only REITs or deep-pocketed investors can do. But the truth is, more individual investors and small partnerships are stepping into this space, especially as the Alberta market heats up.
Still, this isn’t a casual condo flip. Large-scale deals require a different mindset and a lot more due diligence.
In this blog, we’ll walk you through exactly how to analyze a 50-unit apartment building, using a real-world-style scenario, and show you how to break down the numbers like a pro.
Understand the Basics of the Deal
Let’s say you find a 50-unit apartment in southeast Calgary listed for $8.5 million.
Here’s the info you receive from the seller:
- Monthly rent (on average per unit): $1,150
- Annual gross rental income: 50 units × $1,150 × 12 = $690,000
- Vacancy & bad debt estimate (4%): – $27,600
- Other income (laundry, parking): $18,000/year
- Effective Gross Income (EGI): $680,400
That’s your top-line number, the income you can expect after accounting for normal vacancies.
Estimate Operating Expenses
Operating expenses typically range from 35% to 50% of your Effective Gross Income, depending on the building’s condition and management style.
For this property, let’s assume the following annual costs:
- Property Taxes: $78,000
- Utilities (water, gas, electricity): $95,000
- Insurance: $25,000
- Repairs & Maintenance: $40,000
- Management Fees (7% of EGI): $47,628
- Miscellaneous/Admin: $10,000
Total Operating Expenses: $295,628
Calculate Net Operating Income (NOI)
Now subtract the operating expenses from your Effective Gross Income:
NOI = $680,400 – $295,628 = $384,772
This is the income your property produces before mortgage payments, and it’s one of the most important numbers in multi-family investing.
Cap Rate and Market Comparison
The Cap Rate helps you compare income to purchase price:
Cap Rate = NOI ÷ Purchase Price
= $384,772 ÷ $8,500,000 = 4.53%
This might seem low, but in Calgary’s urban multifamily market, cap rates between 4.5%–5.25% are typical for well-located, newer buildings.
Higher cap rates usually come with higher risk or deferred maintenance.
Financing and Cash-on-Cash Return
Let’s assume:
- Down payment: 25% → $2,125,000
- Loan amount: 75% → $6,375,000
- Interest rate: 5.5%
- Amortization: 30 years
- Annual Debt Service (approx.): $431,000
Now calculate your Cash Flow:
Cash Flow = NOI – Debt Service
= $384,772 – $431,000 = –$46,228
Uh oh. You’re in negative cash flow.
This tells us that either the deal is overpriced or it needs a different financing structure (such as CMHC-insured financing under the MLI Select program, which would dramatically reduce payments).
Debt Coverage Ratio (DCR)
Lenders look for a Debt Coverage Ratio (DCR) of at least 1.10 to 1.25 on large multi-family deals.
DCR = NOI ÷ Debt Service = $384,772 ÷ $431,000 = 0.89
This DCR is too low, and the bank will likely say no unless you use CMHC-insured debt with longer amortization.
What Could Make This Deal Work?
- Raise rents by $100/unit = +$60,000/year
- Reduce expenses (self-manage or improve efficiency)
- Refinance using CMHC’s MLI Select for up to 50 years of amortization
- Re-negotiate the price closer to $7.5M for stronger returns

Frequently Asked Questions (FAQs)
A 50 unit apartment investment involves purchasing a residential building with 50 rental units to generate income through rent and potentially benefit from long term property value appreciation.
Evaluate the purchase price, rental income, vacancy rate, operating expenses, net operating income (NOI), cap rate, financing costs, and expected cash flow before deciding whether the property is a suitable investment.
The capitalization rate, or cap rate, measures a property's annual net operating income against its purchase price. In the example discussed in this blog, an $8.5 million purchase price and $384,772 in annual NOI produce an estimated cap rate of 4.53%.
Common expenses include property taxes, utilities, insurance, repairs, maintenance, property management fees, administration, vacancy losses, and financing costs. Investors should also account for major capital repairs.
Investors can explore appropriate rent adjustments, reduce avoidable operating costs, improve occupancy, manage maintenance proactively, and review financing options. Any rent increases must comply with applicable Alberta tenancy rules and lease requirements.
