Return on Equity: When Capital Stops Working
Cash-on-cash freezes on the day you bought. Return on equity asks the question that actually matters five years later.
14.7% → 10.1%
ROE from year 1 to year 15 on one property. It declines — slowly.
The calculation
Return on equity = Annual return ÷ Current equity
Annual return = cash flow + principal paydown + appreciation. Equity = current market value − loan balance.
The distinction from cash-on-cash return is the denominator, and it is the whole point. Cash-on-cash is frozen at the day you bought: it divides by the $67,200 you put in, forever. Your actual capital in the deal is not $67,200 any more — it is whatever you would walk away with if you sold, and that number grows every month through paydown and appreciation.
Which means cash-on-cash answers “was that a good purchase?” and ROE answers “is this still a good place for this money?” Only the second question is actionable, because the purchase is already made.
Fifteen years on one property
The $240,000 example: 25% down at 6.75%, NOI growing 3% a year against a fixed loan payment, the property appreciating 3% a year.
| Year | Equity | Cash flow | Paydown | Appreciation | ROE |
|---|---|---|---|---|---|
| 1 | $69,147 | $995 | $1,947 | $7,200 | 14.7% |
| 5 | $109,248 | $2,885 | $2,512 | $8,103 | 12.4% |
| 10 | $168,996 | $5,568 | $3,529 | $9,394 | 10.9% |
| 15 | $241,967 | $8,686 | $4,919 | $10,891 | 10.1% |
So ROE does decline, and for a specific reason: your equity compounds at roughly the rate of appreciation plus accelerating paydown, while appreciation — the largest component of the return — is a fixed percentage of value. The numerator grows; the denominator grows faster.
The honest version of “your equity is lazy”
The version without appreciation
Strip the forecast out and count only cash flow plus principal paydown — the two components you can actually verify:
| Year | Cash flow + paydown | Equity | ROE excluding appreciation |
|---|---|---|---|
| 1 | $2,942 | $69,147 | 4.3% |
| 5 | $5,397 | $109,248 | 4.9% |
| 10 | $9,097 | $168,996 | 5.4% |
| 15 | $13,605 | $241,967 | 5.6% |
That one rises. Rents grow, the loan payment does not, and paydown accelerates — so the verifiable part of the return improves over time even as the headline ROE falls. Both tables are true, and which one you look at determines whether the property looks like it is decaying or maturing.
When ROE actually justifies acting
The argument is: if this equity would earn more elsewhere, move it. The argument is sound and the hurdle is higher than people account for.
| Route | What it costs | What it must beat |
|---|---|---|
| Sell | 6–9% of value in transaction costs, plus tax on gain and depreciation recapture | Your current ROE, after losing that much of the principal you are redeploying |
| Cash-out refinance | 2–3% closing, a higher rate on the whole balance, and lower DSCR forever | The effective cost of the released cash — about 9.9% on this deal |
| 1031 exchange | Selling costs, two hard deadlines, and a compressed search | Your ROE, with the tax deferral counted as extra buying power |
| HELOC or portfolio line | Interest only when drawn; the first mortgage stays intact | Often the cheapest option, and the one most people skip |
Run the comparison net, not gross
How to use it in practice
Recompute ROE once a year, against a current valuation rather than your purchase price. Most investors never do this, which is why they hold properties long past the point where the capital would do better elsewhere — and equally why others churn perfectly good assets on the strength of a slogan.
Pair it with IRR, which answers the same question over a whole hold rather than a single year, and with the five different things people call ROI, so you know which number you are being quoted.
Frequently asked questions
What is return on equity in real estate?
The annual return a property produces — cash flow, principal paydown and appreciation — divided by the equity currently in it, measured as market value less loan balance. Unlike cash-on-cash return, the denominator updates as the property appreciates and the loan amortises.
Why does return on equity decline over time?
Because equity typically grows faster than the return does. Appreciation is a fixed percentage of a rising value while your equity compounds through both appreciation and accelerating principal paydown, so the denominator outpaces the numerator. The decline is real but gradual — roughly four percentage points over fifteen years in a typical case.
What is a good return on equity for a rental property?
There is no absolute threshold, because ROE is a comparison tool. The meaningful test is whether your ROE beats what the same equity would earn in its next best use, after subtracting the 6 to 9% of transaction costs required to move it.
Should I sell when return on equity drops?
Only if a genuinely better use of the capital clears your current ROE after transaction costs, taxes and the risk of the replacement. A declining ROE is a prompt to run that comparison, not a signal in itself — and a HELOC or portfolio line is often cheaper than either selling or refinancing.
