The short answer
Plan the exit as a sequence of closings, not one event. First decide property by property which sales you will exchange and which you will simply pay tax on; then let lease expirations set the order; then run each exchange on its own 45- and 180-day clock unless you deliberately bundle sales. Under the regulations, bundled sales share the clock of the first closing and one identification list, which compresses your time. A five-property exit usually fits in 18 to 24 months, with DST interests as the place the proceeds land.

Decide property by property which sales you will exchange and which you will simply pay tax on
A portfolio is five separate tax pictures. Pull each property's depreciation schedule and compute the gain a sale would produce: purchase price plus improvements, minus depreciation allowed or allowable, against the expected net price. A condo bought three years ago may have almost no gain, while a duplex held for twenty years may carry most of the portfolio's tax.
Low-gain properties are often cheaper to sell for cash than to exchange, especially if you can place each sale in a year when your other income is modest. In 2026 the 15% long-term rate runs to $613,700 of taxable income for joint filers, and the 3.8% net investment income tax starts at $250,000 of modified AGI, per Rev. Proc. 2025-32 and section 1411. Selling Your Rental Portfolio to Retire works through that split.
Check how each property is titled before you plan the calendar. A rental in one LLC and another in your own name are different taxpayers, and the exchange must be completed by the same taxpayer that sold; the same-taxpayer rule explains the fixes, which take time.
Let lease expirations set the order, because occupied and vacant houses sell to different buyers
An occupied rental with a lease in place sells mostly to investors, who price it on the rent and want copies of leases, deposit records and a rent roll. A vacant house can also sell to owner-occupants, a larger pool for single-family homes and condos. Which one gets the better price depends on the market, so ask your agent property by property.
Map every lease end date on one sheet. Notice periods for ending or not renewing a tenancy come from the lease and your state's landlord-tenant law, so confirm them locally before you give any notice. Avoid scheduling a sale that depends on a tenant leaving on a date you do not control.
At each closing, security deposits and prorated rent are credits to the buyer. Whether those credits create taxable cash for you depends on how the closing statement is drawn; security deposits and rent prorations covers the fix.
Separate exchanges each get their own 45- and 180-day clocks; a bundled exchange runs on the first closing's clock
Under Reg. section 1.1031(k)-1(b)(2), the identification period ends at midnight on day 45 after the transfer, and the exchange period ends at the earlier of day 180 or the due date, including extensions, of your return for the year of the sale. When several relinquished properties are part of the same exchange and close on different dates, both periods are measured from the earliest transfer.
That makes bundling a trade-off. One exchange covering three sales means one identification list and one set of replacement closings, but the property that closes last may have only a few weeks of identification time left. The regulation also caps the list at three properties, or any number up to 200% of the combined value, 'regardless of the number of relinquished properties.'
Separate exchanges avoid both problems. Route each sale through the qualified intermediary under its own agreement and it gets its own clocks and its own list, so a failed purchase in one exchange does not touch the others. Running two or three at once is allowed; the work is keeping the deadlines straight, which 45 days inside 180 days explains.
A hypothetical 24-month calendar for five rentals
Hypothetical portfolio: a condo worth $350,000 with little gain, a newer single-family house worth $450,000 with modest gain, an older house worth $500,000, a duplex worth $700,000 and a fourplex worth $1,200,000 with a $250,000 mortgage, the last three with large gains. The plan below sells the two low-gain properties for cash in separate years and exchanges the three with most of the tax.
Treat the dates as a pattern, not a promise; buyers, inspections and tenants move them. Confirm the tax result of each step with your CPA before you list.
- Months 1 to 3: depreciation schedules, gain per property, lease calendar, title check, a qualified intermediary engaged before the first contract.
- Months 4 to 8: sell the condo for cash; its small gain is taxed this year.
- Months 6 to 12: sell the fourplex in its own exchange; replace the $250,000 of debt and identify DST interests plus one direct property as a backup.
- Months 13 to 18: sell the older house and the duplex as two separate exchanges on overlapping clocks, each with its own list.
- Months 19 to 24: sell the newer house for cash in the second tax year, keeping that year's income below the NIIT threshold if you can.
Finish by consolidating into DSTs, and do not let a late-year sale shorten your exchange period
DST interests suit the last stage because each closing can be split across several trusts and they close on a set subscription process rather than a negotiated purchase. Our traditional DST solutions state that clients often close within 3 to 5 business days, which helps when a portfolio's last exchange is running short of time; how fast any one trust closes still depends on its offering.
Watch the calendar around year-end. A sale on November 1 has 180 days to April 30, but the exchange period ends earlier, on your return due date, unless you file an extension for that year; 1031 and the tax-year straddle shows the fix. For several sales across two years, ask your CPA how the cash sales and the exchanges will stack in each year.
When the last closing is done, you have traded five roofs and five sets of tenants for trust interests that need no management, at the cost of liquidity and control. Moving into a passive portfolio covers how to spread those interests by sponsor and tenant.
Related questions
Can one qualified intermediary handle all five sales?
Yes. Each sale you want treated as its own exchange needs its own exchange agreement and its own clocks, which the intermediary tracks separately.
If I bundle two sales into one exchange, can I identify more properties?
No. The three-property and 200% limits apply to the exchange as a whole, regardless of how many relinquished properties it includes. Separate exchanges each get their own list.
Should the smallest-gain property go first?
Often, because it lets you test buyers and closing logistics on the sale where a mistake costs least. But lease dates and market timing can override that order.
What if one property does not sell?
With separate exchanges, nothing happens to the others; you simply keep that property. A bundled exchange is still valid for the sales that did close, but its clock ran from the first one.
Is there a limit on how many exchanges I can run in a year?
No statutory limit exists. How many times can you 1031 covers the holding-intent questions that frequent exchanges raise.
