The 721 Exchange: Trading Your Building for a Piece of the REIT
A 721 exchange lets a property owner contribute real estate to a REIT's operating partnership tax-deferred, receiving operating partnership (OP) units instead of cash. Under Section 721 of the tax code, contributing property to a partnership for partnership interests isn't a taxable sale — so an owner sitting on decades of appreciation and depreciation recapture can convert a single building into a diversified, professionally managed, income-paying position without triggering the tax bill a sale would.

This guide is for property owners weighing an exit, and for sponsors whose investors keep asking about 'the UPREIT thing': how the structure works, the increasingly common 1031-to-721 two-step, what OP units actually are — and the one-way doors the strategy walks through.
The UPREIT structure: why the loophole is a design
Most REITs are structured as umbrella partnership REITs (UPREITs): the REIT itself owns little real estate directly — it owns a controlling stake in an operating partnership (OP) that holds everything. The structure exists precisely to enable 721 contributions: property owners contribute buildings to the OP (a partnership, so Section 721 applies) rather than to the REIT corporation (which would be taxable). The OP units they receive are the partnership's economic twin of REIT shares — same distributions, typically convertible one-for-one into REIT shares later.
The mechanics in one line
Building → OP units (tax-deferred under §721) → hold and collect distributions → convert units to REIT shares or cash later (taxable then, at your timing) — or hold until death, when the basis steps up and the deferred gain evaporates for heirs.
The estate-planning endgame is a large part of the appeal: OP units held until death receive a stepped-up basis like other appreciated assets, so the deferred gain — often the accumulated appreciation and recapture of an entire investing career — is never recognized at all. 'Swap till you drop' is the folk version; 721 is frequently its final chapter.
The 1031-to-721 two-step
Direct 721 contributions of a private owner's building into an institutional REIT happen, but the retail-scale path runs through Delaware statutory trusts: sell your property in a 1031 exchange into a DST sponsored by a REIT's platform; then, after a seasoning period (commonly two to three years), the REIT exercises an option to acquire the DST's property in exchange for OP units — a 721 transaction that converts your DST interest into OP units, still tax-deferred.
- Step one preserves optionality: the 1031 into the DST is a standard exchange — you could 1031 again later if the 721 never happens.
- Step two ends it: once you hold OP units, you can never 1031 exchange again. OP units aren't real property; the exchange chain is over. Conversion to REIT shares or cash is a taxable event whenever you choose it — but the choice is now between holding units and paying tax, forever.
- The timing is the sponsor's, not yours: whether and when the REIT calls the DST property is the platform's decision. Read the documents for whether the 721 is an option, an expectation, or a certainty — the marketing and the contract sometimes differ.
- Valuation at contribution deserves scrutiny: the exchange ratio (your property or DST interest into OP units at what NAV?) sets your economics permanently, and the sponsor controls both sides of the appraisal.
What owners get — and give up
| Keep the building | 721 into OP units | |
|---|---|---|
| Tax on appreciation | Deferred while held | Deferred until units sold/converted |
| Income | Net rents (with management burden) | Distributions, professionally managed |
| Diversification | One asset, one market | The REIT's whole portfolio |
| Control | Total | None — you're a passive unitholder |
| Future 1031 | Available | Gone forever |
| Liquidity | Sell the building (slow, taxable) | Convert units (taxable) — public REIT shares liquid; private REIT NAV redemption terms apply |
| Estate outcome | Step-up at death | Step-up at death — same endgame |
| Ongoing risk | Your building's performance | The REIT's performance, leverage, and management |
Two subtleties carry most of the regret risk. First, debt: contributed property usually carries a mortgage, and the deal must manage the debt-shift rules — a contributor whose share of partnership liabilities drops below their negative capital account can trigger gain immediately. Structures use guarantees and debt allocations to prevent this; it's the tax engineering at the heart of every UPREIT deal, and it's not optional. Second, concentration in the sponsor: with a private REIT platform, your diversified position is still one manager's NAV, one manager's redemption policy, and one manager's fee stack — the diversification is real at the property level and conditional at the platform level.
Who this serves — and the sponsor angle
- The classic 721 candidate: a long-time owner, often near or in retirement, with large embedded gains and recapture, tired of management, wanting income, diversification, and a clean estate — for whom 'never selling' via step-up is the actual plan.
- The wrong candidate: owners who want to keep compounding through active deals — the 721 ends the 1031 game and converts an operator into a passive holder permanently.
- For syndication sponsors, the 721 is mostly a competitor and occasionally a lesson: DST/UPREIT platforms compete for the same exiting-landlord capital that syndications court. The winning counter-story is return profile and operator alignment — and for sponsors at scale, the UPREIT playbook itself (DST feeder into a perpetual vehicle) is the institutional growth path several private platforms have walked.
- Compliance note for anyone marketing these structures: OP units and DST interests are securities; the offerings run under Reg D, the tax mechanics are individualized, and 'tax-deferred' claims belong next to 'consult your tax advisor' — because whether §721 treatment holds depends on facts (debt, timing, intent) no marketing page can underwrite.
Frequently asked questions
What is a 721 exchange?
A tax-deferred contribution of real estate to a REIT's operating partnership in exchange for operating partnership (OP) units, under Section 721 of the tax code. The owner defers capital gains and depreciation recapture, receives units economically equivalent to REIT shares, and pays tax only if and when the units are converted or sold.
How does a 721 exchange differ from a 1031 exchange?
A 1031 exchanges real property for other real property, preserving the ability to exchange again indefinitely. A 721 exchanges property for partnership units — after which no further 1031 is ever possible, because OP units aren't real estate. The 721 typically ends the deferral chain in a diversified, passive, income-paying position instead of another building.
What is the 1031-to-721 (UPREIT) strategy?
The common retail path: sell your property via 1031 exchange into a Delaware statutory trust sponsored by a REIT platform; after a seasoning period (often 2–3 years), the REIT acquires the DST property in exchange for OP units — a 721 transaction. The result: from your building to diversified OP units, fully tax-deferred, in two steps.
What are OP units?
Limited partnership interests in a REIT's operating partnership — the entity that actually owns the REIT's properties. They pay the same distributions as REIT shares and are typically convertible into shares (or cash) one-for-one. Conversion is the taxable moment, which the holder controls; held until death, the units get a stepped-up basis and the deferred gain is never taxed.
What are the risks of a 721 exchange?
Irreversibility (the 1031 option is gone forever), valuation at contribution (the sponsor influences the exchange ratio that sets your economics), debt-shift rules that can trigger gain if liabilities are restructured, platform concentration (private REIT NAVs, fees, and redemption gates), and the general shift from controlling one asset to passively holding one manager's portfolio.
