Return on equity: should you review the capital already tied up?
Compare rental cash flow with current equity, distinguish gross equity from net sale proceeds, and frame forward scenarios without forecasting from history.

Return on equity compares a defined return with a defined equity amount. For a rental, one useful view is annual cash after debt service and capital spending divided by estimated property equity. It shows cash performance relative to capital tied up in the property.
It is not the only possible return-on-equity definition. Starting, ending and average equity give different results, and cash yield differs from a total return that includes value changes. Label the numerator, denominator and period every time.
Cash invested and current equity answer different questions
Cash invested records what you supplied. Property equity is value minus outstanding debt at a particular date. They can diverge because of closing costs, capital work, principal repayment and changes in value.
The cash-on-cash guide asks how annual cash compares with invested cash. A current-equity view asks how that same cash compares with the property's estimated equity today. Neither percentage automatically tells you which investment you should choose next.
Equity is also not cash you can withdraw freely. Selling involves costs and possible tax or mortgage charges. Borrowing against equity creates debt, qualification requirements and payments. Keep gross equity, net sale proceeds and available borrowing separate.
A hypothetical CAD example
The shared property has an assumed end value of CAD 520,000 and an ending mortgage balance of CAD 397,000. Estimated closing property equity is therefore CAD 123,000. Remaining reserves are a separate cash asset; they are not included in this property-equity denominator.
Annual pre-tax cash after full debt service and actual annual CapEx is CAD 3,000. Divide annual cash by closing property equity:
Here, is the descriptive cash yield, is annual cash under that boundary, and is closing property equity. This comparison requires positive equity.
This describes the past year's cash relative to an estimated year-end equity snapshot. It is not a forecast that CAD 123,000 will earn 2.44% next year. Cash available after additional reserve funding was only CAD 1,500, so a distribution-based view would be about 1.22% on the same equity.
Opening property equity was CAD 100,000. Using that denominator gives 3.0%; using a simple average of opening and closing equity, CAD 111,500, gives about 2.69%. Those are different conventions applied to the same cash. The average here is only a two-snapshot arithmetic average, not a measure weighted for transaction dates.
A falling yield does not prove the rental deteriorated
Suppose, as a separate sensitivity, cash stays CAD 3,000 and debt stays CAD 397,000, but the value estimate rises to CAD 550,000. Equity becomes CAD 153,000 and cash yield falls to about 1.96%. Cash operations did not change; the denominator grew.
Conversely, a lower value can raise this yield by shrinking equity. That would not make a value loss welcome. Near-zero positive equity can also produce a very large percentage. If equity is zero, division is undefined; negative equity needs direct balance-sheet analysis rather than a cheerful yield comparison.
Principal repayment increases equity when other inputs stay fixed, but the full payment has already reduced owner cash flow. If you choose a total-return numerator, reconcile principal and value changes carefully. Do not add principal growth again to a calculation that already includes ending equity.
Turn the snapshot into a forward question
A historical cash yield can prompt a review of the capital tied up today. A decision needs forward scenarios with consistent starting resources and dates.
For a hold scenario, estimate future collections, operating costs, debt service, capital work and an eventual net exit. For a sale scenario, first estimate spendable proceeds after loan payout, selling costs and applicable taxes or charges, then model a specified alternative over the same horizon. For a refinance scenario, carry the new loan, fees and payments through the forecast. Cash released through borrowing is not a gain by itself.
Do not compare gross property equity with an alternative that only receives net sale cash. Also consider risk, liquidity and work required; a return percentage does not measure those directly. Detailed keep-or-sell and equity-release guides explain these comparisons.
Put it to use
Review current equity and cash yield annually, when you obtain meaningful valuation evidence, and before a material transaction. These are suggested review times. If the ratio moves, identify whether cash, debt or value drove it. Check whether last year's capital spending was unusual and whether the valuation supports the apparent change.
Update the forward assumptions before acting. This research establishes no universal healthy return on equity, and a low historical cash yield is a question to investigate rather than an automatic instruction to sell or borrow.
