Buying a Fourplex in Edmonton: What the Sold Data Actually Shows

Christopher Peel · REALTOR®Updated June 7, 202612 min read

Here’s the part most “invest in Edmonton real estate” articles won’t tell you: at today’s rates, a single-family rental or a condo loses money every month. The cap rate sits below the mortgage rate, so you pay to hold it. But that’s only half the story — because in Edmonton, cash flow lives in doors, and the fourplex is where the math finally works.

This isn’t a hunch. It’s what falls out of a comprehensive analysis of real Edmonton sales — every property type, with the actual property taxes, condo fees, and (for the multi-unit set) the rent rolls disclosed in the listings. Here’s what the data shows, and how to run your own deal at the end.

Why a Single Rental Doesn’t Cash Flow Right Now

A rental property’s monthly cash flow is simple: rent, minus operating costs (tax, insurance, maintenance, vacancy), minus the mortgage. The cap rate — net operating income divided by price — tells you the return before financing. The rule of thumb: when the cap rate is below your mortgage rate, leverage works against you and the property bleeds cash monthly.

That’s exactly where Edmonton’s single-unit rentals sat when we ran this in June 2026. Run the median condo and the median house through the math at 20% down and a 4.5% mortgage, and both come out negative:

You’d be buying for appreciation and mortgage paydown, subsidizing the property out of pocket every month to get there. That’s a real strategy, but it’s not the cash-flowing investment most people picture.

Cash Flow Lives in Doors

Look down that table again and the pattern is unmistakable: as you add doors, the economics flip. The same dollar of property buys more rent when it’s split into rentable units, while the big fixed costs — land, foundation, roof, your time — get shared across them.

One door (condo or house): cash-flow negative. You hold it for appreciation.
Two doors (a house with a legal basement suite): you’re roughly at break-even. One mortgage, two rents.
Four doors (a fourplex): genuinely cash-flow positive on the median deal.

This is the quiet reason experienced Edmonton investors gravitate to small multifamily. It’s not glamour — it’s that the fourplex is where the rent finally outruns the mortgage.

What the Fourplex Data Actually Shows

Edmonton fourplexes don’t always announce themselves — many trade as residential listings, not commercial ones. Filtering the sold data to genuine four-door properties (purpose-built fourplexes plus the full side-by-side duplexes with a legal suite on each side that deliver four rentable units), a clear picture emerges:

Where they are: the active four-door inventory concentrated in mature, rentable neighbourhoods — Allendale, Bonnie Doon, Highlands, Montrose, and the university corridor — where tenant demand is deep and steady.

Two Ways In: Investor or House-Hacker

A fourplex isn’t only for someone with deep pockets. There are two genuinely different doors into one, and the down payment is what separates them.

1. The investor: 20% down, rent all four

Buy it purely as an investment and you’ll put 20% down and rent all four units. On the numbers above, that’s genuinely cash-flow positive, before you count appreciation or principal paydown.

2. The house-hacker: live in one, rent three

Here’s the path most people don’t realize exists. If you live in one of the four units, a fourplex qualifies as an owner-occupied home — which means you can buy it with as little as 5% down, not 20%. You live in one unit and your three tenants pay most of the mortgage.

After a few years you can move out, rent the fourth unit, and you own a cash-flowing fourplex.

The Five-Year Picture

Cash flow is only one of the three ways a property pays you. The other two — your tenants paying down the mortgage, and the building appreciating — compound quietly in the background. That’s the difference between an asset that pays you to own it and one you simply hope goes up.

Run the Numbers on a Real Deal

Every property is its own deal — the rents, the condo fees, the condition, the down payment, the rate you can actually negotiate. The medians above are a starting point, not an answer. The best thing you can do before you fall in love with (or write off) a listing is run it through the math honestly. (And once you’re writing the offer, know your closing protections — RPR vs title insurance in Alberta matters double on a multi-building lot.)

If you want to see what is actually on the market right now, every active Edmonton fourplex is listed on our fourplex inventory page, with the price per door worked out on each one so buildings of different sizes compare directly.

That’s exactly what our Edmonton investment property calculator is built for. Punch in a real price and rent, choose 1 to 4 units, flip the owner-occupied switch to see the house-hack version, and it returns the cap rate, cash flow, cash-on-cash return, and a five-year projection — using live Bank of Canada rates, CMHC rents, and the current Edmonton mill rate. No sign-up, no pitch — just the numbers.
