Two Landlords Sold Identical Rentals. Only One Handed Uncle Sam a Check This Year

Two retired landlords sold identical rentals in the same year, and walked away with very different tax bills. The split came down to one decision made before either of them called a real estate agent.

Picture two retired landlords, each with a paid-off rental bought years ago. The houses are twins: same appreciation, same depreciation history, same ready buyers. Both landlords sell. One files a return with a capital gains bill attached. The other owes nothing on the sale.

One decision before closing made the difference. The second landlord ran the sale through a Section 1031 like-kind exchange and rolled the proceeds into another rental. The two landlords are a composite, but the rules that split them apply to any investor sitting on an appreciated property.

Plenty of investors are. The S&P CoreLogic Case-Shiller National Home Price Index reached 337.3 in July 2026, measured against a base of 100 in January 2000. That’s the highest reading in five years. In Charleston, S.C., FHFA data puts five-year price growth at 61.64%.

What Section 1031 Actually Says About Swapping Rentals

The core rule fits in one sentence. 26 U.S.C. § 1031(a)(1): “No gain or loss shall be recognized on the exchange of real property held for productive use in a trade or business or for investment if such real property is exchanged solely for real property of like kind which is to be held either for productive use in a trade or business or for investment.”

“Like kind” covers more ground than it sounds. IRS Publication 544 says real estate for real estate qualifies, including city property for farm property and improved property for unimproved. A rental house can become a small retail building.

There are fences, though. Under § 1031(a)(2), property held primarily for sale is excluded, so house flippers are out. Publication 544 says real property used for personal purposes, such as your home doesn’t qualify either. And under § 1031(h), U.S. and foreign real property aren’t like kind, so a Tucson rental can’t turn into a villa abroad.

Two Deadlines Can Sink the Whole Exchange

The second landlord sold first and bought later, which makes it a deferred exchange. The timer starts the day the old rental transfers. Under 26 U.S.C. § 1031(a)(3)(A), the replacement property must be identified within 45 days. Under § 1031(a)(3)(B), it must be received within 180 days or by the return’s due date with extensions, whichever comes first.

That “whichever comes first” clause is the trap. Sell late in the year and the filing deadline can land before the window closes. Filing an extension keeps the full window open.

Then there’s the cash. Publication 544 treats proceeds as constructively received when they’re “made available for you so that you can draw upon it at any time.” Let the money touch the landlord’s checking account and the exchange fails. That’s why exchanges typically run through a qualified intermediary, who holds the proceeds and closes on the replacement property.

Deferred Gain Follows the Landlord Into the Next Property

Section 1031 postpones the bill. Under § 1031(d), the new property generally takes the old property’s basis. In Publication 551’s example, real estate with a $50,000 adjusted basis and an $80,000 market value is traded for $80,000 of investment real estate. No gain is recognized, and the old basis moves into the new property, so the untaxed gain moves with it.

Cash taken out gets taxed. Under § 1031(b), any money or non-like-kind property (called “boot”) is taxable, limited at the amount of the gain. Publication 544’s example: property worth $100,000 with a $50,000 basis is traded for real property worth $60,000 plus $40,000 in cash. The realized gain is $50,000, and the recognized gain is $40,000, which matches the cash received.

Trading With Relatives Starts a Holding Clock

Under 26 U.S.C. § 1031(f)(1)(C), if the exchange is with a related person and either side disposes of the property within 2 years of the last transfer, the deferral is lost. The gain gets recognized as of that later sale. Publication 544 counts a spouse, siblings, parent, child as related persons, along with corporations you own more than 50% of.

Why the First Landlord Wrote the Check Anyway

A straight sale puts the gain on that year’s return. Publication 544’s current edition lists maximum capital gains rates of 0%, 15%, 20%, 25%, and 28% for 2025. On a rental, the part of the gain that comes from past depreciation is unrecaptured section 1250 gain, taxed at up to 25%. The rest lands in the 0%, 15% or 20% levels based on taxable income.

For 2025, Publication 550 caps the 0% levels at $96,700 of taxable income for joint filers and $48,350 for individual filers. Rates fill like a glass: a large sale stacks on top of pensions and IRA withdrawals, and only the dollars above each line get the higher rate. State tax may come on top, depending on where the landlord lives.

Paying up still bought something: a clean exit. No intermediary, no deadlines, no inherited basis on the next deal, and cash free for anything. The exchanger kept every dollar of equity invested and earning rent. If that landlord keeps exchanging and holds until death, heirs generally get a stepped-up basis that wipes out the deferred gain.

Who Should Defer and Who Should Cash Out

Deferral fits the landlord who wants to stay in real estate, already has a replacement property in mind, and can hit both deadlines without cutting corners. Selling outright fits the landlord who’s done with tenants and repairs, needs the money for retirement income or care costs, or wants simplicity more than a postponed bill. Before you list the property, run the numbers both ways with a CPA.
