How to Calculate Return on Equity on a Rental Property

How to calculate return on equity on a rental property

To calculate return on equity (ROE) on a rental property, divide your property's total annual return by the equity you currently have tied up in it:

ROE = Annual total return ÷ Current equity

That single ratio tells you how hard the money trapped in your property right now is actually working — which is a very different question from "was this a good deal when you bought it?"

Most investors obsess over cash-on-cash return, which measures return against your original cash invested. ROE is the metric seasoned operators use to decide whether to hold, refinance, or sell a property they already own. As equity builds through appreciation and loan paydown, your return on that equity quietly erodes — and ROE is how you catch it.

Why ROE matters more over time

When you buy, your equity is small (your down payment plus closing costs), so even modest returns look strong. Five or ten years later, you might be sitting on $150,000 in equity earning the same $9,000 a year it earned when you had $40,000 in the deal.

That's a classic case of lazy equity. The dollars are there, but they've stopped performing. ROE forces you to confront it.

Rule of thumb: if a property's ROE drops below what you could earn by redeploying that equity elsewhere — another down payment, a 1031 exchange, even a lower-effort asset — it's a signal to act, not to coast.

The two inputs you need

1. Current equity

Current equity is today's market value minus your outstanding loan balance:

• Current market value — what the property would realistically sell for now, based on recent comps, not what you paid.
• Current loan balance — the remaining principal on your mortgage.

For a cleaner number, subtract estimated selling costs (agent commissions, closing, transfer taxes — often 6–8% of value) to get net equity. That reflects the cash you could actually pull out, which is the honest denominator.

2. Annual total return

This is where ROE gets more complete than cash-on-cash. A rental produces return in four ways:

• Annual cash flow — net income after all expenses and debt service. If you're fuzzy on this, nail down your monthly rental property cash flow first.
• Principal paydown — the portion of your mortgage payments that reduces the loan balance (your tenant building your equity).
• Appreciation — the annual increase in property value. Use a conservative, market-based number, not a hopeful one.
• Tax benefits — the after-tax value of depreciation and deductions, if you want a fully-loaded figure.

Add these together for total return. You can calculate ROE on cash flow alone for a conservative view, or include all four components for true total-return thinking for buy-and-hold.

A worked example

Say you bought a single-family rental five years ago. Here's where it stands today:

• Current market value: $340,000
• Loan balance: $205,000
• Gross equity: $135,000
• Estimated selling costs (7%): $23,800
• Net equity: ~$111,000

Now the annual return components:

• Cash flow: $4,200
• Principal paydown: $4,800
• Appreciation (3% of $340,000): $10,200
• Tax benefit (estimated after-tax value): $1,800
• Total annual return: $21,000

ROE on gross equity: $21,000 ÷ $135,000 = 15.6%

ROE on net equity: $21,000 ÷ $111,000 = 18.9%

That still looks healthy. But watch what happens if you strip out appreciation (which you can't spend and can't count on) and tax benefits:

Cash-flow-only ROE: $4,200 ÷ $135,000 = 3.1%

That 3.1% is the sobering number. The dollars locked in this property are generating a passbook-savings cash return. The deal looks great only because you're banking on appreciation. ROE exposes exactly how much of your return depends on hope versus hard cash.

How to use ROE in real decisions

Hold, refinance, or sell

• Hold when ROE comfortably beats your alternative uses of capital and the property is low-hassle.
• Refinance or do a cash-out when a large chunk of dead equity could be redeployed into a higher-returning deal — just stress-test the new payment against cash flow first.
• Sell or 1031 exchange when ROE has fallen below your target and better opportunities exist. Mind the 1031 exchange rules and timelines so you don't trip a taxable event.

Set an ROE floor

Many investors set a personal threshold — often somewhere in the 8–12% range on net equity — below which a property goes on the "review" list. There's no universal "good" number; it depends on your market, leverage, and what else you could buy.

Common mistakes to avoid

• Using purchase price instead of current value. ROE is a forward-looking metric. Stale value inputs make it meaningless.
• Ignoring selling costs. Gross equity overstates what you could actually redeploy. Net equity is the honest denominator.
• Counting appreciation you can't defend. Use a conservative, market-grounded rate — not last year's hot streak.
• Confusing ROE with cash-on-cash. Cash-on-cash uses original cash invested; ROE uses current equity. Both matter, but they answer different questions. See cap rate vs cash-on-cash return for how the metrics stack up.
• Running it once and never again. ROE changes every year as equity grows. Recalculate annually.

Keep the inputs real

ROE is only as trustworthy as the numbers behind it — today's value, a defensible appreciation rate, accurate remaining loan balance, and real cash flow. Guess any of those and the ratio lies to you. This is where pulling live, verified market data beats typing assumptions into a spreadsheet: tools like PropertyWiz AI pre-populate current value, rent, taxes, insurance, and appreciation from real market data, so your ROE reflects reality instead of optimism.

Run ROE across your whole portfolio once a year. The properties with the lowest ratios are your best candidates for a refinance or sale — and often your biggest hidden opportunities.
