The Challenge
Alberta is one of the most landlord-friendly provinces in Canada: no rent increase cap (landlords can raise rent by any amount with three months' written notice), no rent control, and security deposits capped at one month's rent. For an investor considering a multi-unit property in Calgary's northeast, this regulatory backdrop changes the underwriting calculus significantly — the challenge is not rent ceilings, but financing in a higher-rate environment and finding a property that actually cash-flows without aggressive assumptions.
In this illustrative scenario, the investor is looking at a 1970s triplex in Calgary's Northeast quadrant (Marlborough area) listed at $620,000. Three units: a two-bedroom main floor at market rent of $1,750/month, a two-bedroom upper unit at $1,650/month, and a smaller one-bedroom basement suite at $1,200/month — total gross rent of $4,600/month. At a 20% down payment ($124,000) and a five-year fixed rate of 5.74% with 25-year amortization, the question is whether the property can generate positive cash flow after all carrying costs, and whether the cap rate justifies the purchase price in the current market.
The Approach
Using Astrilio's mortgage payment calculator, the investor determined that the principal and interest payment on a $496,000 mortgage at 5.74% over 25 years came to approximately $3,088/month. From the $4,600 gross monthly rent, the investor deducted 5% vacancy ($230), property taxes ($450/month based on the 2024 municipal assessment), insurance ($120/month), and a conservative 8% management fee ($368/month) for a total of $1,168 in monthly operating costs. Net operating income (before mortgage) came to $3,432/month, or $41,184 annually.
The cap rate calculator confirmed a cap rate of 6.64% at the $620,000 purchase price — above the 5.5–6.0% typical for Calgary multi-family in this cycle, suggesting modest value at the asking price. The cash flow calculator showed positive cash flow of +$344/month — thin but genuinely positive. Running the DSCR calculation confirmed the loan qualified at a debt service coverage ratio of 1.11, above most lender minimums. The investor modelled a rent increase of $100/unit two years after acquisition (permitted without cap in Alberta), which improved projected cash flow to +$544/month and the DSCR to 1.18 — a more comfortable buffer.
Key Takeaways
The absence of rent control in Alberta is often cited as the province's headline investor advantage, but the more practical benefit for a seasoned underwriter is the absence of ceiling risk — you don't need to model what happens if rent can never rise above today's guideline. That said, positive cash flow in a higher-rate environment is not automatic simply because Alberta has no caps. The real test is whether the income, at market rents today, covers debt service with a meaningful buffer.
In this scenario, the $344/month positive cash flow represents a very thin margin — approximately 7.5% of gross rent. A single extended vacancy, an emergency plumbing repair, or a rate reset at renewal that adds 50 basis points would either compress or eliminate that cash flow. The value of this scenario is not that the numbers are exciting; it's that they're realistic, and they give the investor a clear picture of the downside.
The strength of Alberta multi-family is the upside optionality. When the mortgage renews in five years, property values may be higher and rents will almost certainly be higher (there is no limit on how much the landlord can increase them between tenancies). The investor in this scenario is, in effect, buying a modestly cash-flowing asset in a market with unrestricted rent growth potential — the opposite bet from a rent-controlled Toronto property with stronger day-one cash flow numbers that carry ceiling risk in the long run.
