Cap Rate Explained: Rental Property ROI in Edmonton

Cap rate tells you what a rental property earns before financing, in one number you can compare across listings. This guide shows you exactly how to calculate it for an Edmonton property, using recent sold prices and current CMHC rent data, so you can judge a deal in minutes instead of guessing.

What Cap Rate Actually Measures

Cap rate, short for capitalization rate, is the annual return a property would produce if you paid all cash. The formula is simple:

Cap Rate = Net Operating Income ÷ Purchase Price

The logic is the same one analysts use for any yield: divide an annual income figure by the value of the asset that produces it. Cap rate uses the property's purchase price as that denominator and its NOI as the income.

Because cap rate ignores your mortgage, it lets you compare a $250,000 condo against a $500,000 house on equal footing. Two properties can have the same price but very different cap rates once you account for rent and expenses. That is the whole point: it isolates the property's earning power from your financing choices.

How to Calculate Net Operating Income

NOI is the engine of the cap rate. Start with your annual gross rent, then subtract operating expenses. Here is what counts.

The CRA lists deductible rental operating expenses on Form T776: property taxes, insurance, repairs and maintenance, management and administration fees, utilities you pay, professional fees, advertising, and interest and bank charges. For NOI you typically use the operating items and leave out financing.

What you must not include in NOI:

• Mortgage principal. The CRA is explicit that you cannot deduct the repayment of principal on your rental loan. It is not an operating expense.
• Land transfer tax. Alberta has no land transfer tax anyway, and the CRA confirms land transfer taxes paid on acquisition are added to the cost of the property, not deducted against rent.
• The value of your own labour. If you do the repairs yourself, you cannot expense your time.

A Worked Edmonton Example

Let's price a deal using current Edmonton numbers. Suppose you buy a property near the residential median sold price, which recent MLS sold data puts at roughly $477,000 for Edmonton homes.

Now estimate rent. CMHC's October 2025 survey put Edmonton's average 2-bedroom purpose-built rent at $1,603 per month, or $19,236 a year. A house often rents higher than a purpose-built apartment, but we will use this as a conservative anchor.

Subtract realistic operating expenses. A common Edmonton expense load runs 35% to 45% of gross rent once you include property taxes, insurance, repairs, management, and a vacancy allowance. At 40%, expenses are about $7,694, leaving an NOI of about $11,542.

Cap Rate = $11,542 ÷ $477,000 = 2.4%

That low number is the honest math at a single-family price point. It is why many Edmonton investors look at condos or multi-unit setups, where rent is higher relative to price.

The live data above shows why the purchase price drives everything. Active list prices in Edmonton skew higher than sold prices, so paying close to the sold median, not the asking median, protects your cap rate from the start.

Why Condos Often Pencil Better

Run the same math on an entry-level condo and the picture changes. Edmonton's condo median sold price sits near $250,000 in recent sold data, roughly 53% of the residential median.

Say that condo rents at $1,301, the CMHC October 2025 average for a 1-bedroom. That is $15,612 a year. Condos carry condo fees, so assume a heavier 50% expense load, leaving an NOI of $7,806.

Cap Rate = $7,806 ÷ $250,000 = 3.1%

Higher than the house, because rent does not fall as fast as price does. This is the core reason entry-level Edmonton investors lean toward condos and basement-suite homes: the rent-to-price ratio is friendlier.

Cap Rate Versus Cash Flow

Cap rate is not your bank balance. It deliberately ignores the mortgage, so two investors buying the same building at the same cap rate can have wildly different monthly cash flow depending on their down payment and rate.

To see your actual monthly position, layer in financing. Model your payment with the hômm mortgage calculator, then subtract that payment from your NOI to find real cash flow. Remember the CRA rule: only the interest portion is deductible, not the principal, so your tax picture and your cash position are two different things.

This split matters because the numbers are slim industry-wide. Across Canada, Statistics Canada tax data for the 2020 filing year showed 76.3% of landlord families reported a profit, with a median net rental income of $4,880 among that profitable group. Net rental income made up only 2.3% of total family income for most landlords. Treat rentals as a long hold, not a quick win.

Using Cap Rate to Compare Listings

The fastest way to use cap rate is as a screen. Pull rent comparables, estimate expenses at 40% to 50% of gross rent, and divide NOI by the asking price. Anything well below your target gets cut before you book a showing.

When you are ready to compare specific Edmonton properties, browse live inventory on hômm's Edmonton property search and run each candidate through the cap rate calculator to rank them apples to apples.

Frequently Asked Questions

What is a good cap rate for an Edmonton rental property?

There is no single official benchmark, and no approved data source publishes a fixed Edmonton range, so judge each deal on its own math. Higher is generally better for income, but a very high advertised cap rate can signal deferred maintenance or an inflated rent assumption. Compare the property's cap rate against other Edmonton listings you have screened and against the rent CMHC reports for that bedroom type.

Does cap rate include my mortgage payment?

No. Cap rate is calculated on Net Operating Income, which excludes all financing. The CRA also confirms you cannot deduct mortgage principal as a rental expense. To see your actual monthly cash flow, calculate your mortgage separately and subtract it from your NOI.

How do I calculate Net Operating Income for a rental?

Take your annual gross rent and subtract deductible operating expenses. The CRA's T776 list includes property taxes, insurance, repairs and maintenance, management fees, utilities you pay, professional fees, advertising, and bank charges. Do not subtract mortgage principal, land transfer tax, or the value of your own labour.

Is a condo or a house a better cap rate in Edmonton?

Entry-level condos often show a higher cap rate because rent does not fall as steeply as price. Edmonton's condo median sold price near $250,000 is about 53% of the residential median near $477,000, while a 1-bedroom rent of $1,301 is well above half of a house's rent. Condo fees offset some of that advantage, so always run the full NOI both ways.

How does Edmonton's lack of rent control affect cap rate?

With no rent control under Alberta's Residential Tenancies Act, landlords anywhere in Alberta can reset rent to market when a unit turns over. CMHC found Edmonton had the smallest vacant-versus-occupied rent gap (5%) among major Canadian cities in 2025, versus 44% in Toronto. That freer pricing supports long-run NOI and protects your cap rate as rents rise.
