The duplex that became a job

Patricia bought her duplex in 2000 for $180,000. She was a hospital administrator with a steady paycheck, and the rental was meant to supplement it. For twenty-five years it did, along with the tenant calls, the repairs, the vacancies, and the paperwork that come with being a small-time landlord.

By 2025 she was 68 and ready to retire. Her career savings and Social Security were in place. What she wanted was to stop working, and the duplex had quietly become the one job she couldn't quit. It was also her largest asset outside her retirement accounts: worth about $625,000, up from the $180,000 she paid.

That gain was the problem.

What selling outright would have cost

Patricia's cost basis started at roughly $180,000. Over the years she claimed depreciation, the annual deduction a landlord takes for wear on a building, which lowered her adjusted basis to around $120,000. Selling at $625,000 would have produced a taxable gain of about $505,000.

On a straight sale, the numbers ran roughly like this:

• Federal long-term capital gains tax, at 20%: about $101,000
• Depreciation recapture, at 25%: about $95,000. When you sell, the IRS taxes back the depreciation you deducted over the years, at a rate up to 25%.
• State tax, at a combined 5%: about $25,250
• Total: about $221,250

That is roughly 35% of the sale price gone to tax, leaving about $404,000 to put back to work. At 68, Patricia wanted that money earning for her without another building to run.

What Patricia wanted from the next chapter

She and her advisor, Lisa, worked through four questions.

How much income did she actually need? Between savings and Social Security, her basic expenses were covered. The duplex netted about $18,000 a year, or $1,500 a month, money that improved her life but wasn't keeping the lights on.

How long could she lock up her capital? Her health was good, she had no large medical costs on the horizon, and she was thinking in terms of a 10-15 year window before estate planning took over. She could commit for years.

How concentrated was she? Entirely. One property, one location, one set of tenants.

And what would she trade for a hands-off arrangement? She said she'd accept income well below the duplex's, somewhere around 50 to 60 percent of it, if her management workload dropped to zero.

That last answer pointed at a specific tool: a 1031 exchange into a portfolio of DSTs. A 1031 exchange is the rule in Section 1031 of the tax code that lets a real estate investor postpone capital gains tax by rolling the proceeds from one investment property into another "like-kind" property within set deadlines. A DST, or Delaware Statutory Trust, lets many investors each own a fractional beneficial interest in professionally managed commercial real estate, and the IRS treats that interest as like-kind property, so it can serve as a 1031 replacement.

Selling, and starting the clock

Patricia listed the duplex in early 2025. It was well kept, the market was active, and within about six weeks she had an acceptable offer at $625,000, with closing set for June 15.

She told the buyer she'd be doing a 1031 exchange, which meant the sale proceeds had to pass through a qualified intermediary: a neutral third party who holds the money so the seller never takes possession of it. Touch the cash, even briefly, and the exchange is disqualified. Buyers in commercial real estate see this often, so the mechanics were routine.

On June 15, 2025, the sale closed. Her net proceeds of $625,000, after commissions and closing costs, went straight to her intermediary, ABC 1031 Exchange Services. She never handled a dollar of it.

Then the two 1031 clocks started: 45 days to formally identify her replacement property, and 180 days to close on it.

Three properties, three states

Lisa found three DST offerings that fit Patricia's profile. Each spread her money across a different property type and a different part of the country.

That put all $625,000 to work, with projected distributions of $26,690 a year, about $2,224 a month.

The three sat in three states, Florida, Georgia, and Tennessee, and three sectors. If Tampa's apartment market softened, the medical office and the warehouse wouldn't necessarily move with it. That spread was part of the appeal.

Patricia submitted her identification to the intermediary on day 20, well inside the 45-day limit. All three met the identification rules and were documented properly.

Closing inside the 180-day window

DST closings run on their own schedule, since they depend on the sponsor finishing its capital raise. Patricia's three came in over about a month:

• Tampa multifamily: July 8, 2025 - $280,000 deployed
• Atlanta medical office: July 22, 2025 - $200,000 deployed
• Nashville industrial: August 5, 2025 - $145,000 deployed

All three closed well within the 180-day window from her June 15 sale. The exchange was complete and compliant.

The first checks

By September, Patricia's statements showed her beneficial interests in each trust. Her first distributions landed in October 2025:

• Tampa: $1,050
• Atlanta: $667
• Nashville: $507.50

That was $2,224.50, deposited electronically. No tenant calls. No chasing late rent. No contractor to schedule, no repair to approve.

The pattern held every month after. A quarterly statement would arrive from one sponsor or another, and she filed it. Her one recurring task was collecting the K-1 forms each January, the tax form that reports an investor's share of a partnership's income, for her return.

After twenty-five years of landlording, the quiet was startling.

The tax bill that didn't come

Her 2025 return showed the point of the whole exercise. She had sold a property for a $505,000 gain in June and owed zero capital gains tax on it.

The roughly $221,250 that a straight sale would have sent to the IRS and the state stayed invested across the three DSTs instead.

Deferral is not forgiveness. The gain still exists, now attached to her new holdings. But the tax dollars keep working in the meantime. Lisa's illustration, assuming a 4% annual return, put the extra growth on that deferred $221,250 at more than $26,000 by year five and around $100,000 by year ten.

What actually changed

Patricia had walked in ready to accept less income for less work. The projected distributions came in the other direction: about $2,224 a month against the $1,500 the duplex had netted. But the number she talked about wasn't the size of the check. It was the character of it, automatic, spread across three properties and three states, and asking nothing of her.

For twenty-five years she'd carried a landlord's mental load: tenants, maintenance, insurance, property tax, the low hum of administrative overhead. At 68, it was gone. She told Lisa the drop in stress was worth more to her than any dollar figure. She spent the reclaimed attention on her grandchildren, travel, and hobbies.

Where it got bumpy

It wasn't frictionless. Her main worry was timing. She identified her three properties well inside the 45-day window, but the closings didn't begin until July and ran into August, and for a few weeks she fretted the deal wouldn't come together in time. Lisa kept pointing her back to the rule: identification was what the 45-day deadline required, and that was already done; the closings only had to land within 180 days. When the last one closed on August 5, the worry lifted.

The other friction was paperwork. The DSTs reported her income, depreciation, and return of principal differently from the rental schedule she knew, and the K-1s came with unfamiliar terms. Her tax preparer walked her through it, but there was a learning curve.

The plan for the end

By early 2026, Patricia had held the interests about eight months, the distributions had kept coming, and Lisa had turned the conversation to what happens at the end.

Patricia's plan is to hold the DSTs for life. Under current law, when she dies her heirs inherit at a stepped-up basis, meaning the asset's value resets to its market value on the date of death, which erases the built-up gain. The roughly $505,000 she deferred during her lifetime would disappear entirely, and her heirs would receive about $625,000 in real estate with no capital gains liability attached.

That is what turns deferral into something larger: what she postpones, her heirs may never owe.

What Patricia's case shows

A few patterns stand out from her experience, less as instructions than as things worth understanding.

An exchange is administratively easier to handle before full retirement, while there's still bandwidth for the paperwork. Patricia moved while she had it.

Concentration carries its own weight. One property in one place felt riskier to her than three properties in three states, even before any dollar changed hands.

Going passive is an adjustment, not only a relief. Some people find handing off control liberating; others find it disorienting. Patricia had to get used to not being "involved" anymore.

And the estate math is where 1031 exchanges get most interesting: a gain deferred through life can be eliminated at death.

For Patricia, the exchange was never mainly about taxes. The deferral was the mechanism; the point was getting to stop being a landlord while her capital stayed invested. As of early 2026, that is where she is, an investor with diversified, hands-off holdings, no longer on call for anyone's plumbing. Whether the same trade fits anyone else depends on their income needs, their tolerance for locking up capital, and their estate goals.
