Gross yield is the simplest way to compare rental properties — it tells you how much rent you collect each year as a percentage of what you paid for the property. No costs, no expenses, just raw rent divided by price.

Investors use it to do a first pass. If you're looking at ten properties, gross yield helps you quickly rule out ones that don't make sense before you spend time on detailed math. A property showing 3% gross yield in a market where 5.5% is normal? Not worth digging deeper.

The major problem is what it leaves out: every single cost. Property tax, insurance, maintenance, condo fees, vacancies, management fees — none of that is included. So gross yield always shows you the best-case number, not the realistic one. Sellers and listing agents love quoting gross yield for exactly this reason.

The price-to-rent ratio tells you how many years of rent it would take to equal the purchase price. A lower number means a market is more favourable for investors — you're paying less per dollar of rent. A higher number means prices are expensive relative to what you can charge in rent, making cash flow harder to achieve.

The rule of thumb: below 15 generally favours investing. Between 15 and 20 is workable with the right property. Above 20, it becomes very difficult to generate positive cash flow without a large down payment. Above 25, you're essentially betting on appreciation — not income.

This metric is most useful for comparing cities and neighbourhoods before you start shopping. It prevents you from wasting time searching for cash flow deals in markets where cash flow is structurally impossible.

Net yield deducts all operating expenses from your rental income before dividing by the purchase price. This gives you a realistic picture of what the property earns after the actual costs of running it.

Expenses you must include: property tax, building insurance, condo fees (if applicable), maintenance and repairs (typically budget 1% of property value per year), a vacancy allowance of 5–8% (even in a tight rental market, units sit empty between tenants), and property management fees of 8–12% if you're not self-managing.

If you do self-manage, your time has a value. The hours you spend dealing with tenants, coordinating repairs, and handling paperwork aren't free — they're just not being counted. Accounting for your time honestly will usually lower your net yield further.

Net yield is the metric that separates investors who are doing the real math from those who aren't.

Cap rate (capitalization rate) answers a specific question: if you bought this property in cash with no mortgage, what annual return would you get? To calculate it, you take the Net Operating Income — rent minus all operating expenses, but not including any mortgage payment — and divide it by the property's current value.

By removing the mortgage from the equation, cap rate becomes a pure measure of the property itself. This is why it's the standard tool for comparing properties side by side. Two properties with very different financing structures can still be fairly compared using cap rate.

Cap rate is also how commercial real estate investors value properties — the cap rate essentially tells you how the market prices the income stream. In a market with 5% cap rates, if you can acquire a property generating higher NOI than market rents, you've found a value play.

One critical nuance: cap rate uses current market value in the denominator, not what you originally paid. As your property appreciates and its market value rises — but your rent stays flat — your cap rate on current value quietly drops. This is important to track over time.

Cash-on-cash return (CoC) measures what you actually earn on the cash you put in — your down payment, closing costs, and any immediate repairs — after paying all expenses including your mortgage. This is what makes CoC different from cap rate: it includes your financing costs, so it reflects your real-world experience.

If your CoC is 5%, it means every $100,000 you invested is generating $5,000 in annual cash flow — money you can actually spend or reinvest. If your CoC is negative, you're writing a cheque every month to hold the property. That's not automatically a bad decision, but it needs to be a conscious one backed by a clear thesis.

CoC is also where leverage shows its power. Because you're using a mortgage to control a much larger asset, your returns on the cash you put in can be significantly higher than they would be if you bought in cash. A property with a modest cap rate can have a strong CoC when financed well — and conversely, rising mortgage rates can turn a positive CoC negative without any change to the property itself.

As your property appreciates and your mortgage pays down, your equity grows. But your cash flow usually doesn't grow at the same pace — rents tend to increase slowly, and your operating costs go up over time. This creates a quiet problem: the return you're earning on your equity keeps shrinking, even if the property is performing fine on paper.

Think of it this way. If you bought a property with $80,000 down and it's now worth $600,000 with a $250,000 mortgage, your equity is $350,000. If you're making $400/month cash flow, your ROE is only about 1.4% — worse than a savings account. That's a lot of equity doing very little work.

ROE doesn't mean you should automatically sell — but it forces you to ask the right question: if I sold and redeployed this equity into a new investment, could I earn more? Sometimes the answer is yes, and that insight can unlock significantly more return over a long-term investing career.

Most investors ignore ROE entirely. They check their returns at the time of purchase, feel good about the original numbers, and never recalculate as the property evolves. Reviewing ROE annually is one of the most underused habits in real estate investing.

Every yield metric we've looked at so far — gross yield, net yield, cap rate, CoC — measures only the income your property generates. None of them capture what the property is worth when you eventually sell. Total return fixes that by combining all three sources of return: the cash you pocketed along the way, the equity your mortgage paydown built, and the gain from the property increasing in value.

In Calgary over 2019–2024, appreciation was the dominant return driver for most residential investors — far outpacing rental income in total dollar terms. A property with weak cash flow in a neighbourhood that appreciated 40% over five years likely outperformed a high-yield property in a flat market, even accounting for the monthly top-ups on the negative cash flow.

Understanding total return changes how you think about deal selection. It means a slightly negative cash flow property in a high-growth area can be a better investment than a strongly positive cash flow property in a stagnant market — if you have the liquidity to sustain the holding cost during the hold period.

The danger is using this thinking as a rationalization. Appreciation is real but it's not guaranteed, not predictable, and not in your control. Cash flow is the part of the return you can actually depend on. Model your deal to work on cash flow alone — and let appreciation be the bonus.

Debt Service Coverage Ratio (DSCR) answers a simple question: does the property generate enough income to cover its own debt? A DSCR above 1.0 means yes — the property pays for itself. Below 1.0 means you're subsidizing it from outside income. At exactly 1.0, you're breaking even on debt service, with no cushion for surprises.

Lenders use DSCR to evaluate commercial and investment properties. Many institutional lenders require a minimum DSCR of 1.1 to 1.25, meaning the property needs to generate 10–25% more income than its debt obligations — that buffer covers unexpected vacancies, maintenance costs, or small rent drops without threatening loan repayment.

For you as an investor, DSCR is a stress-test tool. It tells you how much the deal can absorb before going underwater. A property with DSCR of 1.3 can handle a significant rent drop or interest rate increase before it starts costing you money every month. A property at 0.85 DSCR is already fragile — any negative change in income or expenses makes your situation worse.
