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 sit today. 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% downand 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.)

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.
