He’s Swapped One Rental for Another Three Times Since 1994 and Never Paid a Dollar of Capital-Gains Tax. If He Still Owns the Last One the Day He Dies, Nobody Ever Will
A landlord can trade one rental for a bigger one, repeat that move across decades, and potentially hand the entire stack of appreciation to heirs without a penny ever reaching the IRS. The legal path exists right now, but one…

If you own a rental property with a stack of appreciation you never want to hand to the IRS, Section 1031 of the tax code has a door most landlords never walk through. A like-kind exchange lets you sell one investment property and roll the entire proceeds into another without recognizing gain in that tax year. Do it repeatedly, hold the last property until you die, and your heirs may owe zero federal income tax on decades of appreciation. The nickname for that combination is “swap till you drop,” and it lives in current law.
How a 1994 Duplex Quietly Grows Into a 2026 Building
Let us walk through an example with clear assumptions. Imagine buying a small duplex back in 1994 for $150,000. In 2004, you exchanged it for a fourplex worth $400,000. In 2013, you traded up again to an apartment building valued at $900,000. Then, in 2022, you rolled that into a mixed-use property worth $2 million. Three like-kind exchanges, one investor, and not a dime of capital gains tax paid along the way. The tax code calls that a deferral because the gain was postponed, not erased. Each swap carried your original cost basis forward, which is what you originally paid, adjusted for improvements and depreciation. By 2026, you could be sitting on a $2 million property whose basis is still tied to that 1994 duplex.
Statute Behind the Magic Trick
The exchange mechanic lives in Internal Revenue Code Section 1031. The payoff at death is in Section 1014, which gives heirs a stepped-up basis equal to the property’s fair market value on the date of death. In plain English, your children inherit the building as if they bought it for $2 million the day you died. Every dollar of deferred gain from every prior exchange disappears for income tax purposes. So does the depreciation recapture, the tax normally owed on all those annual depreciation deductions a landlord claims. Unrecaptured Section 1250 gain is taxed at a federal rate of up to 25% on an ordinary sale, and exchanges defer it right along with the capital gain. The step-up at death wipes both away.
Who Qualifies and Who Doesn’t
Both properties must be held for investment or business use. A primary residence does not qualify. A flip you bought primarily to resell does not qualify. And since the Tax Cuts and Jobs Act took effect on January 1, 2018, only real property qualifies. Older articles describing 1031 exchanges of equipment, artwork, or vehicles are obsolete. If someone pitches a like-kind swap of anything other than real estate, walk away.
Steps and the Clock
- Hire a qualified intermediary before closing. This independent third party holds the sale proceeds. If you ever touch the money, the IRS treats it as constructive receipt, and the exchange collapses.
- Close the sale of your current rental.
- Formally identify the replacement property within 45 calendar days of that closing.
- Close on the replacement within 180 calendar days of the original sale. Both clocks run concurrently, include weekends and holidays, and missing either one collapses the exchange and makes the full gain taxable.
- Match or exceed the price and the debt. Any cash you pocket or debt relief you fail to replace is called boot, and boot is taxable to that extent.
Gotchas Nobody Advertises
Once you start exchanging, you are effectively locked into the strategy for life. An ordinary cash sale detonates decades of accumulated gain all at once. On a $2 million property with a basis tethered to a 1994 purchase, selling rather than exchanging exposes up to $1.85 million in gain to a 20% federal capital gains rate, the 3.8% net investment income tax, and a 25% unrecaptured depreciation recapture tax.
That massive tax bill forces landlords to manage tenants and repairs deep into old age or keep exchanging into new properties.
Trading properties is also harder in a sluggish transaction market. The Case-Shiller National Home Price Index reached 331.9 in June 2026, while annualized existing-home sales stood at just 4.09 million units. Finding an acceptable replacement property within a strict 45-day window in a low-inventory environment creates immense pressure.
The tax outcome is genuinely remarkable. It also requires never selling. Your heirs inherit both the property and the decision, which is exactly the kind of handoff we mapped out (beneficiary forms, titling, the works) in a free estate checklist.
