From DST to REIT: How a 721 Roll-Up Actually Works

A lot of DSTs are not built to be held forever. They are built to end inside a real estate investment trust. The sponsor packages a property as a Delaware Statutory Trust, sells beneficial interests to 1031 investors, holds for a few years, and then at full cycle the sponsor's affiliated REIT acquires the property. Instead of cashing out and triggering tax, DST investors contribute their interests to the REIT's operating partnership and receive operating-partnership units. That contribution is what the industry calls a 721 roll-up or an UPREIT transaction, and it changes the math on which DST you should buy in the first place.

What a 721 roll-up actually is

Start with the structure. A Delaware Statutory Trust holds a property, or a small pool of properties, and sells fractional beneficial interests to investors completing a 1031 exchange. Those investors get passive ownership, the sponsor handles management, and the position is treated as like-kind real estate for 1031 purposes. That is the front end, and it is covered in our DST guide. The 721 roll-up is the back end.

When a DST is structured with a 721 exit in mind, the sponsor also operates a REIT, usually a non-traded REIT, that sits above a string of these trusts. At the end of the DST's hold, the sponsor's REIT acquires the DST property. Rather than buying it for cash, which would close out the DST investors and trigger their deferred gain, the REIT lets investors contribute their DST interests into the REIT's operating partnership. In exchange, investors receive OP units. The mechanic is named for the tax code section that allows it, Section 721, which lets a taxpayer contribute property to a partnership in exchange for a partnership interest without recognizing gain.

The shorthand for the whole arrangement is UPREIT, short for umbrella partnership REIT. The REIT does not own properties directly. It owns units in an operating partnership, and the operating partnership owns the real estate. That umbrella structure is what makes the 721 contribution work, because you are contributing into the same partnership the REIT itself holds. The full sequence from exchange to units is laid out in our piece on the 1031-to-721 exchange.

The sequence, step by step

The roll-up is the last move in a chain that often starts years earlier. The typical path runs like this. You sell an investment property and do a 1031 exchange into a DST. You hold the DST through its life, which is usually five to ten years. The sponsor reaches full cycle and offers a 721 contribution into the affiliated REIT's operating partnership. You contribute your DST interest and receive OP units. Later, on your own schedule, you can convert OP units into REIT shares, and from there sell shares for cash. Each handoff has a different tax effect, which the table below sets out.

Stage	What happens	Tax effect
1031 into the DST	You exchange your relinquished property for DST beneficial interests through a qualified intermediary.	Gain deferred under Section 1031.
Hold to full cycle	The DST holds the property, typically five to ten years, and distributes income along the way.	Distributions taxed as earned; deferred gain stays deferred.
721 contribution	The sponsor's REIT acquires the property; you contribute your DST interest to the operating partnership for OP units.	No gain recognized under Section 721; deferral continues.
Hold OP units	You hold a partnership interest in the operating partnership and receive distributions, reported on a K-1.	Distributions taxed; deferred gain still riding inside the units.
Convert to REIT shares	You elect to convert OP units into REIT common shares, usually one-for-one or per a stated ratio.	Conversion is generally a taxable event; deferred gain is realized at conversion.
Sell shares	You sell REIT shares, in pieces or all at once, for cash.	Capital gain or loss measured from your basis in the shares.

Two things are worth pinning down. The roll-up is not instant liquidity. It moves you from one private, illiquid position into another, just with a larger and more diversified pool underneath it. And the timeline is set by the sponsor, not by you. You hold the DST until the sponsor decides to go full cycle, then you decide whether to accept the 721 offer. The point where you finally control the schedule is later, when you choose when to convert units and when to sell shares.

Continued deferral, and why the roll-up is not a sale

The reason the 721 roll-up exists is tax. Section 721 says that when you contribute property to a partnership in exchange for an interest in that partnership, you generally do not recognize gain or loss. The DST interest is the property you contribute. The OP units are the partnership interest you receive. So at the roll-up itself, you do not pay tax. The gain you originally deferred with your 1031 exchange does not come due. It keeps riding forward, now embedded in your OP units.

This is the part investors most often get wrong. They assume that because the REIT bought the building, they got cashed out and owe tax. In a properly structured 721 transaction, that is not what happens. You did not sell. You contributed, and you took back units instead of money. The deferral that started when you first exchanged into the DST continues uninterrupted. The gain is not erased, just postponed again, the same way it was when you went from your original property into the DST.

The catch comes later. Continued deferral lasts only as long as you hold the units. The moment you convert OP units into REIT shares, you generally trigger a taxable event and the deferred gain is realized. So the 721 buys you more deferral time, but it sets up a future tax bill at conversion, unless something intervenes first. The most common intervening event is death, which we cover further down, because a step-up in basis can wipe the deferred gain out entirely for heirs.

OP units, explained plainly

An OP unit is a unit of ownership in the REIT's operating partnership. It is not a REIT share, and the distinction matters. A REIT share trades like a security, gets a 1099, and in a non-traded REIT can be redeemed through the sponsor's redemption program. An OP unit is a partnership interest. It reports to you on a Schedule K-1, not a 1099, which means your tax preparer has more to chew on each year. Our dedicated explainer, OP units explained, walks through the reporting in more detail.

Economically, OP units are usually designed to track REIT shares closely. They typically carry the same distribution rate per unit as the REIT pays per share, and they are generally convertible into REIT shares at a stated ratio, often one-for-one. That convertibility is the bridge to liquidity. You hold units for continued deferral, then convert to shares when you want to start selling. Conversion is the taxable line. Hold units, no tax on the conversion you have not done yet. Convert, and the deferred gain generally comes due on the units you converted.

Because conversion is taxable and is something you control, OP units give you a dial. You can convert and sell a slice each year to manage which bracket the realized gain lands in, rather than recognizing the whole deferred gain at once. That staged liquidity is one of the practical attractions of the structure, and it is the opposite of the single-day tax hit you would take if the DST had simply sold the building for cash at full cycle.

Why the roll-up changes how you pick the DST

Here is the practitioner point that most DST buyers miss. If a DST is built to end in a 721 roll-up, then your eventual outcome is not really about the building the DST holds today. It is about the REIT you end up inside. The original property is a way station. The destination REIT is where your money actually lives for the long run, and where your distributions, your downside, and your liquidity all come from.

That flips the diligence order. Most investors study the DST property hard and never look at the sponsor's REIT, because the REIT feels like a someday problem. With a 721-structured DST, the REIT is the main event. Before you buy the DST, look through to the destination REIT and study its portfolio mix, its property-level and entity-level leverage, its distribution history and whether distributions have been covered by cash flow or partly funded by return of capital, and its redemption program terms including any gates and limits. Our checklist on DST sponsor due diligence applies here, and so does the REIT guide.

The practical filter is simple. Read the DST private placement memorandum, but read it for the exit, not just the entry. A property with a great in-place tenant means little if it rolls up into a REIT carrying heavy leverage and a redemption queue that is already backed up. The reverse is also true. A merely adequate DST property that contributes into a large, well-capitalized REIT with a deep portfolio and a functioning redemption program may be the better long-term position. Pick the DST for where it lands, not for where it starts. Our note on how to review a PPM covers what to flag.

The path to liquidity

The roll-up does not make you liquid. It puts you on a path toward liquidity that you can walk at your own pace. After you hold OP units, you convert them into REIT shares when you are ready, then sell shares. In a non-traded REIT, selling usually means using the sponsor's redemption program, where the REIT buys back shares at a stated price on a periodic schedule.

Redemption programs are the key liquidity feature and the key liquidity risk. They are not the same as selling a public stock. They typically cap how much can be redeemed per quarter and per year, often expressed as a percentage of total shares or net asset value. They frequently carry a holding period before you can redeem at all, and an early-redemption discount if you sell sooner. And the board can usually suspend or limit redemptions, which sponsors have done in stressed markets when too many holders head for the exit at once. So the liquidity is real but conditional. You can sell shares in pieces over time, which is a genuine advantage, but you cannot assume you can sell everything on any given day at full value.

The upside of the staged path is control over timing and taxes. Because you decide when to convert and sell, you can spread realized gains across tax years and redeem gradually as you need cash, rather than taking one large taxable event. That flexibility is part of why investors accept the structure despite the redemption limits.

The one-way door

The single most important thing to understand before you accept a 721 offer is that it is permanent in one direction. Once you contribute your DST interest into the REIT's operating partnership, you can no longer do a 1031 exchange out of that position. A 1031 exchange requires like-kind real property on both sides. OP units and REIT shares are securities, not real property, so they do not qualify. The exchange optionality you had inside the DST is gone the moment you roll up.

That is a real cost, and it is why the roll-up should be a deliberate choice rather than a default. Inside a DST, when the trust goes full cycle, you generally have the option to 1031 again into a new DST or another like-kind property and keep deferring through real estate. Accept the 721 and you trade that ability away. From then on, your deferral is tied to holding units, and your eventual exit is taxable at conversion rather than deferrable through another exchange. The tradeoff can be worth it for diversification, scale, and estate planning, but it is a tradeoff, not a free upgrade. The downsides are detailed in our piece on 721 exchange downsides.

Estate planning and the step-up

For older investors, the one-way door looks very different, because of how the tax code treats assets at death. When you die, your heirs generally receive a stepped-up basis equal to the fair market value of the units or shares on the date of death. The deferred gain that has been riding forward since your original 1031, through the DST, through the roll-up, simply disappears for income-tax purposes. Heirs can then sell at the stepped-up basis with little or no capital-gains tax on the prior appreciation.

This is where the 721 structure does some of its best work. The one-way door stops being a problem if the plan was always to hold for life. The investor gets continued deferral and steady income during life, and the heirs get a clean basis at death. OP units add a second estate-planning advantage over a single building. Units divide cleanly among multiple heirs, where a single property does not. Three children can each inherit a third of a unit position without anyone having to sell, partition, or fight over a building. Our note on 721 exchange estate planning covers the mechanics, and basis step-up rules can change, so this needs a current read with your own advisors.

Is the roll-up mandatory or optional?

It depends on the offering, and the answer is usually in the DST private placement memorandum. In many 721-structured DSTs, investors are offered a choice at full cycle. Take cash, recognizing the deferred gain and paying tax, or accept the 721 contribution into the REIT and continue deferring. Some structures lean heavily toward the roll-up, and a few are designed so that the 721 is the expected and primary exit, but a forced contribution with no alternative is something you want to know about before you invest, not after.

Read the PPM specifically for the exit terms. Look for whether the 721 is optional or mandatory, whether there is a cash alternative and on what terms, who controls the timing of the roll-up, the conversion ratio between OP units and REIT shares, and the redemption terms you will inherit. If the exit is described vaguely, that vagueness is itself a flag. Knowing the exit terms before you commit is the difference between choosing the structure and having it chosen for you.

The risks you inherit

A 721 roll-up moves your risk from one building to a whole REIT, and that cuts both ways. You gain diversification across a portfolio. You also inherit everything about that REIT, including the parts you did not choose. Three risks deserve specific attention.

• Entity-level leverage. The destination REIT carries its own debt across its portfolio. If that leverage is high or maturing into a tough financing market, it affects your position even though you never signed for it.
• Distribution sustainability. A headline distribution rate is only as good as the cash flow behind it. Check whether distributions have been covered by operating cash flow or partly funded by return of capital or new investor money, which is not durable.
• Redemption-queue risk. Your liquidity depends on the redemption program staying open and funded. If too many holders redeem at once, the program can hit its gates or be suspended, and you wait.

None of these are reasons to avoid 721-structured DSTs. They are reasons to study the destination REIT before you commit, because once you roll up, these are your risks. The original DST property is a small part of the picture by then. The REIT's balance sheet, payout discipline, and redemption capacity are what determine how the position behaves through a full market cycle. Our explainer on DST full cycle shows where the roll-up fits in the life of the trust.

Who the roll-up fits

The structure fits a specific investor. It suits someone who wants to keep deferring gain, values diversification across a portfolio over a single concentrated building, is comfortable trading away the ability to 1031 again, and either plans to hold for life and pass a stepped-up basis to heirs, or wants staged liquidity they can manage across tax years. It fits older investors especially well, because the step-up at death turns the one-way door from a cost into a feature.

It fits poorly for an investor who wants to keep their real estate genuinely 1031-eligible, who needs predictable near-term liquidity, or who is not prepared to underwrite the destination REIT. For that person, a conventional DST that goes full cycle and lets them 1031 again, or direct real estate, keeps options open that the roll-up closes. As with everything here, the structure is a tool with a job. Match it to your timeline and your estate plan, study the REIT you are landing in, read the PPM for the exit, and the 721 roll-up does exactly what it is built to do.
