A 721 exchange, often called an UPREIT contribution, moves real property into a real estate investment trust's operating partnership in exchange for operating partnership units, deferring gain under Section 721 rather than Section 1031. A 1031 exchange replaces one property with another and keeps the owner holding real estate directly, or through a qualifying structure like a Delaware statutory trust.
The two produce very different outcomes on the other side of closing. A 1031 exchange keeps the owner in the driver's seat of a specific property. A 721 exchange trades that seat for a security in a professionally managed portfolio the owner does not control.
An owner contributes real property to an operating partnership, usually the entity beneath a real estate investment trust, and receives operating partnership units instead of cash. Under Section 721, no gain is recognized on the contribution itself, similar in spirit to how Section 1031 defers gain on a property-for-property trade. The contribution is generally negotiated directly with the REIT or its operating partnership, often through a sponsor that specializes in these transactions.
Those units can typically be held indefinitely, converted to REIT shares, or redeemed for cash, and it is generally that later conversion or redemption that triggers recognition of the deferred gain, not the original contribution. The specific redemption terms, timing, and any lock-up period are set by the operating partnership agreement, not by the owner.
A 1031 exchange requires a qualified intermediary to hold sale proceeds, a written identification of replacement property within 45 days, and a closing on that replacement property within 180 days. The owner ends up holding another piece of real property, sized and located according to their own criteria, rather than a security in someone else's portfolio.
Because the replacement is still real property, the owner retains the ability to exchange again in the future, something that generally is not available once a 721 contribution has been made.
A 721 contribution converts direct property ownership into a security: operating partnership units tied to a diversified, professionally managed portfolio, typically paying distributions that mix ordinary income and return of capital. The owner gives up voting control, leasing decisions, and the ability to select individual assets, in exchange for exposure spread across many properties rather than concentrated in one.
A 1031 exchange keeps the owner in direct or DST-structured real property, with continued exposure to that specific asset's performance, leasing risk, and capital needs, along with the ongoing ability to exchange again rather than cashing out. Concentration risk in a single property or market is the trade-off for keeping that control.
Some owners use a two-step sequence sometimes described informally as a 1031-into-721 strategy: first completing a 1031 exchange into a qualifying Delaware statutory trust, then later contributing that DST interest to an operating partnership under Section 721 once the sponsor's offering documents permit it. This keeps the 1031 deferral intact through the first step and only converts to a security at the second step, on the owner's own timing.
Whether a given DST interest can actually be contributed this way depends entirely on the sponsor's approved offering documents and structure, not on any general rule, so this needs to be confirmed deal by deal rather than assumed.
Real property held through a completed 1031 exchange generally receives a basis step-up at the owner's death under current estate tax rules, which can eliminate the deferred gain for heirs entirely. Operating partnership units received in a 721 contribution also get a basis step-up at death as a general matter, but the partnership's inside basis in the contributed property typically does not adjust to match without a separate election, which is a detail worth raising with a tax preparer rather than assuming away.
On liquidity, operating partnership units are often easier to convert to cash over time through redemption programs than a wholly owned property is to sell, which is one of the real advantages 721 contributions offer owners tired of illiquid direct ownership.
