When to sell a rental property: a return-on-equity framework

Most sell-or-keep advice for rentals is written by someone who profits when you transact: the brokerage that wants the listing, the iBuyer that wants the house, the essayist who wants you to chase a feeling. None of them lead with the one number that actually settles it. The question is not whether your rental still cash-flows. It is whether the equity now locked inside it is earning a return you would accept if that same pile of cash were sitting in your bank account today.

A property you bought eight years ago for $260,000 with $60,000 down can look like a winner on paper while quietly being a poor place to keep money. The mortgage is smaller, the value is higher, and you might be sitting on $180,000 of equity that throws off $7,000 a year. That is a 3.9% return on equity. The cash-on-cash number you fell in love with at purchase is irrelevant now. This page gives you the framework to see that clearly, then the after-tax math to know what you would actually walk away with.

Return on equity is the metric that decides it

Cash-on-cash return measures your annual cash flow against the cash you put in at purchase. That number is frozen in the past. It never updates as your equity grows, so it tells you nothing about whether today's equity is working hard. If you want a refresher on the input, the worked version lives in the cash-on-cash return guide.

Return on equity fixes the blind spot. The formula is one line:

Return on equity = annual pre-tax cash flow ÷ current equity

Current equity is today's market value minus your loan payoff and your estimated selling costs, usually 7% to 9% of the sale price once you add agent commission, transfer taxes, and the small repairs every buyer asks for. Run the worked example from the intro: $7,000 of annual cash flow against $180,000 of equity is 3.9%. Now ask the only question that matters: if someone handed you $180,000 today, would you buy this exact property at this exact price for a 3.9% return? If the honest answer is no, you are holding it out of habit, not analysis.

• Below 5% return on equity is a yellow flag for most markets. A paid-off index fund or a different property may beat it without the tenant calls.
• Appreciation can rescue the number, but only count it honestly. If the home reliably gains 4% a year, add that to the cash-flow yield before you judge. Do not assume double-digit appreciation forever.
• Compare against your real alternative, not a fantasy. The alternative is whatever you would actually do with the freed cash: pay down a higher-rate loan, buy a better-located rental, or sit in cash and wait.

The non-financial reasons to sell that are still real

A clean spreadsheet is not the whole story. Some sells are correct even when the return on equity looks fine, and pretending otherwise is how landlords stay stuck.

• The property fights you every month. A 1920s fourplex with knob-and-tube wiring and a parade of late-paying tenants can clear your return threshold and still ruin your year. Time and stress are real costs the math tends to hide.
• Your portfolio is concentrated in one place. Three doors on one block is one zoning change or one bad employer leaving town away from a problem. Selling to diversify is a defensible move even when the unit pencils.
• You are approaching a life change. Retirement, a move, or plainly wanting fewer obligations are legitimate inputs. The job of the framework is to tell you the price of that choice, not to overrule it.

The tax math you have to run before you list

Here is where most online “signs it is time to sell” lists go quiet, because the after-tax number is the one that hurts. When you sell a rental, the gain splits into two pieces taxed at two different rates, and you report it on Form 4797 with the capital-gain portion flowing to Schedule D. The governing rules are in IRS Publication 544.

Layer one: depreciation recapture. Every year you owned the rental, you deducted depreciation against your income. At sale, the IRS takes that back. The total depreciation you claimed (or could have claimed, which is why skipping it never helped) is taxed as unrecaptured Section 1250 gain at a federal rate of up to 25% for the 2026 tax year. If you depreciated $76,000 over your hold, that slice is taxed first, separate from your capital gain. The mechanics of how that figure builds up are in the rental property depreciation guide, and the at-sale recapture detail is in depreciation recapture when you sell.

Layer two: capital gain. Everything above your adjusted basis, after recapture is carved out, is long-term capital gain if you held more than a year. Adjusted basis is your original price plus capital improvements minus the depreciation you took. State income tax sits on top of both layers. For the full worked sale, including the order the numbers stack, see selling a rental property: the taxes.

Walk a hypothetical. Say you sell that $260,000 duplex for $440,000. Adjusted basis is $260,000 plus $20,000 of improvements minus $76,000 of depreciation, which is $204,000. Total gain is $440,000 minus $204,000, or $236,000. Of that, $76,000 is recaptured depreciation taxed up to 25%, and the remaining $160,000 is long-term capital gain. Add selling costs of roughly 8% and your state rate, and the difference between gross sale price and money in your pocket can run six figures. You cannot judge return on equity against alternatives until you know the net.

When a 1031 exchange changes the answer

If your analysis says sell but you still want to own real estate, a 1031 exchange under Form 8824 lets you defer both the recapture and the capital gain by rolling the proceeds into another investment property. The deadlines are unforgiving: 45 days to identify replacements and 180 days to close, with the proceeds held by a qualified intermediary the entire time so you never touch the money.

The exchange is the right tool only when you want to redeploy into a better property, not when you want out of being a landlord. Deferring tax to buy something you do not really want is how people end up chained to a worse asset. The full rules, timelines, and the cases where you should skip it are in the 1031 exchange guide for small landlords. One footnote: if you once lived in the property, a brief window under Section 121 may shelter part of the gain, but the rules for converted residences are narrow and worth a CPA conversation before you count on them.

A simple annual review that catches the right moment

The best sell decisions are not made in a panic after a bad turnover. They fall out of a habit. Once a year, ideally when you close your books for December, do four things for each property.

1. Update current value. Pull two or three recent comps or a broker price opinion. Do not reuse last year's guess.
2. Recompute equity and return on equity. Value minus payoff minus estimated selling costs, then divide annual cash flow by that equity.
3. Estimate the after-tax net. Run the recapture and capital-gain layers so you know what selling actually nets this year.
4. Compare to your real alternative. If freed equity would clearly beat the property's return, the sell case is open. If not, you keep it for one more year and look again.

This is also where having your accumulated depreciation and current equity already tracked per property saves you. I built rents.ai because the spreadsheets I kept for my own units across two time zones dropped exactly these figures, the running MACRS total and the current equity, that the recapture estimate and the return-on-equity math both need. It will surface those two numbers and a rough federal estimate, but it does not file your return or replace the CPA who signs off on the sale, and the market value you compare against is still a number you enter. The tool organizes the inputs. The decision stays yours.
