Should I sell my rental property?
Every landlord asks it eventually — after a brutal tenant turnover, after a hot market headline, after watching the mortgage statement barely move. I spent months trying to answer it for my own rental with a spreadsheet, and the spreadsheet kept lying to me. Not because the arithmetic was wrong, but because I was comparing the wrong two numbers.
The gut versions of this decision fail in both directions. "Never sell real estate" ignores that some rentals quietly earn less than a savings account. "Take the money and run" ignores taxes that can eat a six-figure hole in the check. The honest answer requires putting two numbers side by side — and both of them are harder to compute than they look.
The question is really two questions
First: what would I actually walk away with if I sold? Not your equity. Not the Zestimate minus the mortgage. The after-tax check — what's left after selling costs, depreciation recapture, federal capital gains, the 3.8% net investment income tax, state tax, and the loan payoff. For most landlords this number is dramatically smaller than the equity they think they have, and recapture is usually the reason. Our free calculator computes it line by line for any sale year.
Second: what does keeping actually earn? This one gets underestimated just as badly, because rent minus mortgage payment misses three of the four ways a rental builds wealth.
What keeping actually earns: four engines
1. Cash flow. Rent minus everything — mortgage payment, property tax, insurance, HOA, and an honest allowance for vacancy and repairs. Many rentals that feel profitable are roughly break-even here, and that's fine, because cash flow is only one engine of four.
2. Principal paydown. Every payment, your tenant buys a slice of your building for you. On a young loan it's small; a decade in, it's often the largest engine nobody counts.
3. Appreciation. The slow, lumpy one. Use a conservative long-run rate for your market, not the last three years extrapolated forever.
4. The depreciation shelter. The deduction that offsets your rental income on paper, often zeroing out the tax on your cash flow. It runs for 27.5 years from the date the property became a rental — and it's the engine with a hidden cost, because every dollar of it is added to your recapture bill at sale, whether or not you actually claimed it.
Here's what the four engines look like on the property I use as the running example across this site — a condo bought for $505,000, worth about $686,000 today, rented at $3,500 a month, with a $427,612 refinance from 2021 at 2.625%:
| Engine (2026, condo example) | Roughly per year |
|---|---|
| Cash flow rent − P&I, HOA, property tax, insurance; before vacancy & repairs | $2,800 |
| Principal paydown tenant-funded equity | $10,700 |
| Appreciation at a conservative 2.32% | $15,900 |
| Depreciation deduction shelters the rental income; grows the recapture bill | $18,364 |
| Wealth accrual from keeping cash flow + paydown + appreciation | ≈ $29,400 |
Notice the shelter isn't in the total — it's not new wealth, it's tax protection on the cash flow, borrowed from the future. And notice what's carrying this particular property: a 2.625% mortgage. Cheap leverage locked in years ago is an asset in its own right, and it's one you surrender the day you sell. If this same condo carried a 7% loan, the cash flow engine would run deeply negative and the whole picture would flip.
What selling actually frees up: the check, not the equity
On paper this condo has about $308,000 of equity. Here's what a sale actually produces, computed by the same engine that runs our calculator — and how both the check and the tax bill move if you wait:
| Sale year | Projected price | Total tax | After-tax check |
|---|---|---|---|
| 2026 — sell now | $686,000 | $62,585 | $203,840 |
| 2027 | $701,915 | $72,176 | $220,016 |
| 2028 | $718,200 | $81,841 | $236,751 |
| 2029 | $734,862 | $91,582 | $254,060 |
| 2030 | $751,911 | $101,401 | $271,957 |
| 2031 | $769,355 | $111,300 | $290,457 |
Two curves worth staring at. The check grows about $87,000 over five years — that's the four engines doing their work. But the tax bill grows about $49,000 over the same stretch, roughly $10,000 a year, because every year adds another $18,364 of depreciation to the recapture pile and more appreciation to the taxable gain. Waiting isn't free; it's a bet that the engines outrun the tax meter. Here, they do — but not by as much as the price growth suggests.
The comparison that settles it
Now the two numbers can finally meet. Keeping this condo accrues roughly $29,400 a year. Selling frees $203,840 — invested at, say, 6%, that's about $12,200 a year. On raw math, keeping wins here, and it isn't close. The reasons are instructive: the tenant covers the costs, the cheap mortgage supplies leverage no one gets in 2026, and the depreciation shelter keeps the IRS out of the cash flow for now.
But run the same comparison with different inputs and it flips fast. A 7% mortgage, softer rent, an HOA that jumps $300 a month, or a market where appreciation stalls — suddenly keeping earns less than a boring index fund, with a tenant, a roof, and a special assessment attached. That's why the framework matters more than anyone's verdict: annual accrual from keeping, versus after-tax proceeds times your realistic alternative return. Two numbers. The rest is noise.
The tiebreakers that override the math
The Section 121 deadline — the one with a clock. If the rental used to be your home and you lived in it 2 of the last 5 years, up to $250,000 of gain ($500,000 filing jointly) can be excluded. That window slams shut about three years after you move out, and when it applies, it can dwarf every other factor — a six-figure exclusion for selling by a date. Two sharp edges: it never covers depreciation recapture, and gain earned during rental years has proration wrinkles. If you're near this window, this is CPA-now territory.
The 1031 exchange — the tax meter, paused. Swap into another investment property and the gain and recapture defer into the replacement. It's a defer, not an erase — and the 45-day identification and 180-day closing deadlines are unforgiving — but it changes the question from "sell or keep" to "keep this one or trade it for a better one."
The step-up at death — the tax meter, erased. Hold until you die and your heirs receive the property at its market-value basis. The deferred gain and the entire recapture bill vanish. It's the strongest never-sell argument in the tax code, and it's why "I'll let the kids deal with it" is sometimes a genuinely optimal strategy rather than procrastination.
The human factors. Concentration — is half your net worth one building in one zip code? Liquidity — do you need the money for something that matters more? And landlord fatigue, which is real, uncompensated, and allowed to be the deciding vote. No spreadsheet gets to overrule your 2 a.m. phone-call tolerance.

Is it better to sell a rental property or keep it?
It comes down to one comparison: what keeping earns each year (cash flow, principal paydown, appreciation, and the depreciation shelter) versus what your after-tax proceeds could earn elsewhere. The proceeds — not your gross equity — are the honest opportunity cost, because selling costs and four layers of tax come out before you see a dollar.
Does waiting to sell increase the taxes?
Usually. Each year adds another year of depreciation to the recapture bill and more appreciation to the taxable gain — roughly $10,000 a year of additional tax in the example above. The check usually grows too; the question is which grows faster for your property.
Can a 1031 exchange avoid the tax?
It defers it — the gain and recapture carry into the replacement property. Paired with holding until death and the stepped-up basis, deferral can become permanent. The 45-day identification and 180-day closing deadlines are strict.
What if the rental used to be my home?
Section 121 can exclude up to $250,000 of gain ($500,000 married filing jointly) if you lived there 2 of the last 5 years — a window that closes about three years after moving out. It never covers depreciation recapture, and rental-period gain has proration rules worth professional review.
When does keeping clearly win?
Low locked-in mortgage rate, positive cash flow, depreciation still running, long horizon — and especially if the realistic plan is holding until the step-up at death erases the deferred tax entirely.
What taxes come out of a rental sale?
Depreciation recapture at ordinary rates up to a 25% ceiling, long-term capital gains at 0/15/20%, the 3.8% net investment income tax above the MAGI thresholds, and state income tax. The recapture guide walks through the biggest and least expected of the four.
