721 Exchange (UPREIT): How DST Investors Enter a REIT

Can you 1031 exchange into a REIT? No — not directly. REIT shares are securities, not real property, so they fail the "like-kind" requirement of Section 1031. But there is a well-established workaround: the two-step 721 exchange, often called an UPREIT transaction. First, you complete a 1031 exchange into a Delaware Statutory Trust. Then, after a holding period, the DST sponsor contributes the property to a REIT's operating partnership under Section 721 of the Internal Revenue Code, and you receive operating partnership (OP) units instead of cash. Your tax deferral continues, and you end up holding an interest in a diversified REIT portfolio.

That's the short answer. The longer answer involves an important trade-off that too many investors discover only after the fact: a 721 exchange is a one-way door. Once you hold OP units, you can never do another 1031 exchange with that money. This article walks through how the 721/UPREIT structure works, what you gain, what you permanently give up, and how to decide whether it fits your situation.

What is a 721 Exchange?

Section 721 of the tax code says that no gain or loss is recognized when property is contributed to a partnership in exchange for an interest in that partnership. It's the partnership-world cousin of Section 1031: both allow you to swap one form of ownership for another without triggering the capital gains tax you've been deferring.

The "UPREIT" part stands for Umbrella Partnership Real Estate Investment Trust. Most large REITs don't own their properties directly. Instead, the REIT owns a controlling interest in an operating partnership (the "umbrella partnership"), and the operating partnership owns the actual real estate. This structure exists largely for tax reasons — it lets property owners contribute real estate to the REIT's operating partnership under Section 721 without recognizing gain.

When you contribute property (or your fractional DST interest, once the trust's property is contributed) to the operating partnership, you receive OP units in return. OP units are designed to be economically equivalent to REIT shares: they typically pay the same distributions and can usually be converted into REIT shares on a one-for-one basis (or redeemed for cash, at the REIT's option). But until you convert or sell, your deferred gain stays deferred — the same gain you've been rolling forward through your 1031 exchanges over the years.

One point worth stating clearly: unlike a 1031 exchange with its 45-day and 180-day deadlines, a 721 exchange has no mandatory gain-recognition date. Your deferral continues indefinitely — until you convert OP units to REIT shares, sell them, or the partnership sells the underlying property in a taxable transaction.

Why You Can't 1031 Directly into a REIT

Section 1031 requires that both the property you sell and the property you buy be real property held for investment or business use. The IRS is explicit that stocks, bonds, and other securities do not qualify. REIT shares are securities — you own stock in a company that owns real estate, not the real estate itself.

A DST interest, by contrast, is treated as direct fractional ownership of the underlying real property under Revenue Ruling 2004-86, which is why DSTs qualify as 1031 replacement property and REITs don't. If you want a deeper comparison of the two vehicles themselves, see our DST vs REIT breakdown.

The UPREIT structure threads this needle. You never exchange real estate for REIT shares. You exchange real estate for a partnership interest — which Section 721 permits tax-free — and that partnership interest happens to be convertible into REIT shares later, whenever you choose (and at a tax cost, as we'll cover below).

The Two-Step Path: 1031 → DST → 721

For most individual investors, the practical route into an UPREIT runs through a DST. Here's the typical sequence:

• Step 1 — Sell and 1031 into a DST: You sell your rental property and complete a standard 1031 exchange into a DST offered by a sponsor with a 721 program, following the normal 45-day and 180-day deadlines. Full capital gains deferral, as usual.
• Step 2 — Hold the DST: The DST operates as a normal DST for a seasoning period, commonly around 24 to 36 months. This holding period matters. If the DST were merely a momentary stopover on the way to OP units, the IRS could argue the whole arrangement was a disguised exchange of real estate for a partnership interest, jeopardizing the original 1031. The seasoning period helps establish that you genuinely held the DST as investment real estate.
• Step 3 — The 721 contribution: The sponsor contributes the DST's property to its affiliated REIT's operating partnership. Your DST interest is exchanged for OP units at a valuation determined at the time of contribution. No tax is due; your deferred gain and your old (low) cost basis carry over into the units.

From that point on, you're no longer a fractional owner of a specific building. You hold units in a partnership that owns the REIT's entire portfolio — potentially dozens or hundreds of properties across markets and sectors.

Timing on step 3 is largely the sponsor's call, not yours. Some programs are structured so the 721 transaction is expected but optional for the investor; others make it effectively mandatory once the sponsor decides to roll the property in. Read the offering documents carefully — more on this below.

What OP Units Give You

Investors don't do 721 exchanges for fun. The structure offers real advantages over staying in single-property DSTs, especially late in life:

• Diversification: Instead of owning a slice of one property (or a handful), you own units backed by the REIT's whole portfolio. A vacancy or a bad roof at any one building barely moves your income.
• Continuing income: OP units typically pay the same per-unit distribution as REIT shares, so you keep receiving regular income, much like DST distributions. How that income is taxed differs from DST rental income — see our guide on how DST distributions are taxed for the baseline comparison, and consult your tax advisor on the partnership K-1 reporting that comes with OP units.
• Liquidity in tranches: This is the headline feature. DST interests are famously illiquid. OP units can usually be converted to REIT shares (or redeemed for cash) — and you can do it a portion at a time. Each conversion is a taxable event, but only for the units you convert. Need $200,000 for a grandchild's house down payment? Convert that much, pay tax on that slice of deferred gain, and leave the rest growing tax-deferred. This staged, as-needed taxation is impossible with a building or a DST.
• Estate planning still works: The step-up in basis at death generally applies to OP units just as it does to real estate. If you hold your units until death, your heirs receive them at fair market value and the deferred gain is eliminated — the same "swap till you drop" endgame that drives the whole DST 1031 strategy. Your heirs then hold an easily divisible, income-producing asset instead of a building they have to manage or sell.
• No more exchange treadmill: When a regular DST sells, you have to scramble into another 1031 within the deadlines or pay the tax. OP unit holders have no such fire drills. There's nothing left to exchange.

The One-Way Door: What You Permanently Give Up

Here's the part that deserves more attention than it usually gets in sponsor marketing materials. A 721 exchange ends your 1031 eligibility forever. OP units are a partnership interest, not real property. Once you hold them:

• No future 1031 exchanges: You cannot exchange OP units — or the REIT shares they convert into — for other real estate, another DST, or anything else on a tax-deferred basis. The exchange chain you may have been building for decades is closed.
• Converting or selling triggers all deferred gain: Your OP units carry your original low basis. When you convert units to REIT shares or sell them, you recognize the accumulated deferred gain on those units — potentially gain rolled forward through multiple exchanges since your first rental property, plus all the depreciation recapture that came along for the ride. If the numbers are large, run them through our capital gains tax calculator before assuming a conversion is affordable.
• No going back: If you later regret the decision — the REIT underperforms, distributions get cut, you'd rather own real estate again — your only exit is a taxable one.

For an investor who fully intends to hold until death and let the step-up wipe out the gain, the one-way door may never matter. For anyone who might want optionality — to move back into direct real estate, to chase better DST offerings, to exchange into a property a child will eventually use — it matters enormously. This is a decision to make with your tax advisor and estate attorney, not from a sales brochure.

Other Risks to Weigh

Valuation at contribution

The number of OP units you receive depends on the value assigned to the DST property at the time of the 721 contribution — a valuation determined by the sponsor and the REIT, both of which sit on the same side of the table. Because the sponsor is affiliated with the REIT acquiring the property, this is an inherently conflicted transaction. A generous appraisal of the REIT's unit price, or a stingy one of your property, quietly shifts value away from you. Ask how the exchange value will be determined and whether independent appraisals are required.

You now own REIT exposure, not a building

After a 721, your wealth rides on the REIT's performance: its leverage, its management, its sector concentration, and — if the units track a non-traded REIT's NAV or a public REIT's share price — market sentiment about real estate securities generally. Real estate and REIT shares don't always move together. In a downturn, publicly traded REITs can fall faster and further than private property values. Distributions can be cut. Non-traded REITs can suspend redemption programs precisely when investors most want out.

Sponsor discretion: "optional" vs "mandatory" 721 programs

Not all UPREIT programs treat you the same way. In some, the 721 transaction is optional at the investor level — when the sponsor rolls the property into the operating partnership, you can elect OP units or, in some structures, take a cash-out (taxable) or attempt another 1031. In others, the offering documents give the sponsor the right to execute the 721 for the entire trust, and every investor goes along whether they planned to or not. If you're buying a DST specifically because you want to keep 1031 exchanging indefinitely, a mandatory-721 program is the wrong vehicle. This is one of several fine-print issues we cover in common DST problems, and it belongs on your due-diligence checklist next to fee loads.

721/UPREIT vs Staying in the DST-to-DST Loop

The alternative to a 721 exchange is the traditional path: when each DST sells, complete another 1031 into the next DST, repeating until death. Here's how the two endgames compare:

Notice what the table doesn't show: a clear winner. The loop preserves flexibility at the cost of repeated fees and deadline stress. The 721 buys simplicity and partial liquidity at the cost of permanent commitment.

Who a 721 Exchange Fits

The UPREIT path tends to make sense for investors who:

• Are done with real estate decisions for good: You've made your last exchange, you want income and simplicity, and you have no desire to ever own a building — or pick another DST — again. Many tired landlords eventually arrive here.
• Plan to hold until death: The step-up at death neutralizes the one-way door. If your units pass to heirs, the deferred gain never comes due.
• Value optional liquidity: You probably won't need the money, but the ability to convert a tranche of units for a medical event or a family need is worth paying tax on that tranche.
• Want a cleaner estate: Units divide neatly among multiple heirs; a fractional DST interest or a duplex does not.

It fits poorly for investors who want to keep the option of returning to direct ownership, who expect to spend down principal during life (every dollar out is a taxable dollar), or who are uncomfortable tying their outcome to a single REIT's management and balance sheet. And because the entry point is a DST purchase, all the usual DST considerations — minimum investments, accreditation, sponsor quality, fees — apply first. Weigh the pros and cons of DSTs before you evaluate the 721 feature on top.

Conclusion

You can't 1031 into a REIT, but the two-step 721 exchange gets you to a similar destination: sell your property, 1031 into a DST with an UPREIT program, and after a seasoning period the sponsor's 721 transaction converts your interest into operating partnership units — with your tax deferral intact and no gain-recognition deadline hanging over you. In exchange for diversification, tranche-by-tranche liquidity, and freedom from the exchange treadmill, you permanently surrender the ability to 1031 again, and any conversion or sale of units triggers the full deferred gain. It's a genuinely good structure for the right investor and an irreversible mistake for the wrong one, so pressure-test the decision with your tax advisor before you sign anything.

Whether or not a 721 program is in your future, every DST investor faces the same fork in the road when their trust's property is eventually sold — roll into another exchange, take OP units if offered, or cash out and pay the tax.
