Timing the 721 Election: Opting In or Out of a REIT Roll-Up

The election calendar is written at subscription, and the first date you can act on is set by the sponsor's option window

A REIT-sponsored DST sells you an undivided interest in a property that the REIT's operating partnership leases back under a long master lease. As compensation for standing behind that lease, the operating partnership keeps a fair market value purchase option over your interest. A 2025 Form 10-K for a non-traded REIT describes the option as exercisable "during a 12-month period commencing two years after the closing of the applicable DST offering, in exchange for OP Units"; a registration statement for a second program says its option can be exercised "any time after two years from the closing of the applicable DST offering in exchange for operating partnership units or cash."

Those dates run from the offering's closing, not from the day you subscribed, so an investor who bought in the first month of a nine-month raise waits longer than the filing suggests. Nothing requires exercise at all. If the operating partnership lets the window lapse, the trust continues under its lease until the sponsor sells to a third party, and that sale is governed by the ordinary rules at what happens when a DST sells.

The practical point is that there is no form to file and no deadline of yours to track until the exercise notice arrives. What you can do is read the trust agreement and the option agreement at subscription so that the window, the consideration and any cash election are known before you commit exchange money. The drafting variations are compared at can I opt out of a DST's 721 roll-up.

Opting in: what accepting units does to your tax calendar

Contributing your interest for operating partnership units is a nonrecognition transaction under section 721(a), which provides that no gain or loss is recognized to the partnership or its partners on a contribution of property in exchange for a partnership interest. Your holding period does not restart: under section 1223(1), the period you held the exchanged property is included when the new property takes the same basis, which it does here.

The gain you deferred through one or more exchanges does not disappear either. Section 704(c)(1)(A) requires the partnership to allocate gain on contributed property so as to take account of the difference between its basis and its value at contribution, and the filings say it plainly: investors who become limited partners "will generally remain tied to the applicable DST Property in terms of basis and built in gain," so a later sale of that property triggers tax on them unless the REIT runs its own exchange, which it is not obligated to do.

Two more clocks start on the contribution date. Section 752(b) treats any decrease in your share of liabilities as a cash distribution, and section 731(a)(1) taxes a distribution to the extent it exceeds your basis in the units, so a trust loan that is not fully replaced by your share of partnership debt can produce gain on day one. And under Reg. section 1.707-3(c), money you receive from the partnership within two years of the contribution is presumed to be part of a sale unless the facts clearly establish otherwise, which is why a redemption of units soon after a roll-up is examined differently from one made years later. The mechanics and benefits of the roll-up itself are at 721 UPREIT roll-ups from a DST.

Opting out: cash elections, third-party sales and continuing with a 1031 instead

Where the program offers a cash election, selling your DST interest to the operating partnership is a disposition of real property, the same as any other sale of your undivided interest. The identification period and exchange period under Reg. section 1.1031(k)-1(b)(2) begin on the date you transfer the property, and the exchange agreement with a qualified intermediary must be signed before that transfer, with your right to receive the money limited until the exchange period ends. Whether a given sponsor will close a cash election through your intermediary rather than paying you directly is a question to put in writing before the exercise date; the filings describe the election but not that logistics step.

Where there is no cash election and the operating partnership exercises for units only, declining is not an option written into the documents; the alternative is a sale of your interest to a third party before exercise, which the trust agreement and securities law make difficult, as described at DST illiquidity and exits. Where the operating partnership does not exercise and the sponsor instead sells the property, one filed program states that the master lease terminates and the master tenant owes the trust the positive difference, if any, between the property's value with the lease in place and the third-party price.

Either way, a cash exit is a new exchange with the full rulebook: identify up to three replacements, or any number within 200% of value, within 45 days, and close within 180 days or your return due date including extensions. A replacement DST from a sponsor that does not carry a purchase option keeps the chain going; the strategy of lining one up in advance is at using DSTs as backup replacement property, and the case for choosing the exchange over the roll-up is at after a 721 UPREIT, can you exchange again.

A hypothetical calendar for $500,000 invested in March 2026

Suppose you close on $500,000 of interests in a DST whose offering closes in March 2026 and whose option follows the first filed program above. The option window opens in March 2028 and closes in March 2029. Your interest carries an adjusted basis of $200,000 from the rental you exchanged out of, so $300,000 of built-in gain rides with it.

If exercise comes in June 2028 and you take units, no gain is recognized that day provided your share of partnership debt at least matches the trust loan you were treated as owning; the $300,000 stays allocated to you under section 704(c), your holding period reaches back to the original rental, and the two-year disguised-sale presumption runs to June 2030. If you redeem 20% of the units in 2031, that is a taxable sale of that slice, carrying its share of the $300,000 plus any change in value. If instead you take the cash election, sign an exchange agreement before the June 2028 closing and identify two replacement DSTs by the 45th day, the $300,000 continues deferred inside the new interests. These are round figures for illustration; run your own numbers with your CPA before the window opens.

Questions to settle before the window opens

Nothing about the election rewards waiting for the notice. The useful work is done in the year before the window: confirming dates, mapping the debt, and deciding which answer fits your plan for the money. If the plan is to keep exchanging, the better time to say so was at subscription, by choosing a trust without a purchase option; the next best time is a cash election closed through an intermediary.

• Pull the exact window dates from the option agreement, measured from the offering's closing, and diary the opening date a year ahead.
• Confirm whether a cash election exists, what share of consideration is promised in cash, and whether the sponsor will wire a cash election to a qualified intermediary.
• Compare your share of the trust loan with the partnership debt you would be allocated, since a shortfall is a deemed distribution under section 752(b).
• Write down your adjusted basis and built-in gain so the section 704(c) exposure is a number, not a surprise.
• Check the unit redemption terms: a one-year holding period in one filed program, redeemed at the REIT's discretion for shares or cash.
• Decide where units fit in your estate plan, since the step-up at death reaches units but the roll-up itself ends exchanging; see DSTs in estate planning.
