What an UPREIT Actually Is
"UPREIT" stands for Umbrella Partnership Real Estate Investment Trust. Under this structure, a REIT does not own its buildings directly — it owns them through an Operating Partnership (the "OP"). A 721 exchange (named for Section 721 of the Internal Revenue Code) lets an investor contribute real estate into that Operating Partnership in exchange for OP units, without triggering the capital gains tax that a straight sale would.
The appeal is the exit it offers. Many people who bought rental property or land decades ago are now sitting on large embedded gains and are tired of being landlords. A 721 exchange is one way to trade an actively managed, concentrated asset for a passive, diversified position — while deferring the tax that would otherwise come due.
The 721 Exchange Mechanics
At its core, a 721 is a contribution, not a sale. You transfer property into the Operating Partnership. In return, the OP issues you units roughly equal in value to what you contributed. Because the tax code treats contributions of property to a partnership in exchange for a partnership interest as non-recognition events, no capital gains tax is due at the moment of contribution.
You now own OP units instead of a deed. Those units typically pay distributions that track the REIT's dividends, and their value rises and falls with the REIT's portfolio rather than with your single former property.
The DST-to-REIT Path (1031, Then 721)
In practice, few individual investors contribute a single building straight into a large REIT. The more common route runs through a Delaware Statutory Trust (DST) and takes two steps:
1. First, a 1031 exchange moves the investor out of their property and into a DST interest, deferring gain under Section 1031. 2. Later, a 721 exchange occurs when the sponsor's REIT acquires that DST and the DST's real estate is contributed into the REIT's Operating Partnership — investors receive OP units.
This is why you'll hear the DST-to-REIT path described as a "two-step" or "UPREIT-eligible DST." The 1031 handles the initial exit; the 721 completes the move into the REIT.
OP Units, Conversion, and the Tax Bill
OP units are generally convertible into REIT shares — but on the holder's own timeline, and usually after a holding period. This conversion is the point most marketing glosses over: converting OP units into REIT shares is a taxable event. At conversion, the deferred gain is generally recognized.
The upside is control over timing. Because you elect when (and often how much) to convert, you can spread conversions across tax years, coordinate them with lower-income years, or hold the units for life and pass them to heirs.
Benefits: Liquidity, Diversification, Passive Income
- ›Liquidity — once OP units convert to REIT shares, those shares can typically be sold, giving access to value that was previously locked in one illiquid building.
- ›Diversification — instead of one property in one market, you own a slice of a larger, professionally managed portfolio across property types and geographies.
- ›Passive income — distributions arrive without tenants, toilets, or turnover; management is the REIT's job.
- ›Estate planning — see below.
Trade-Offs and the One-Way Door
A 721 exchange is generally a one-way move. Once real estate has been contributed into the Operating Partnership, it is no longer eligible for a future 1031 exchange — you cannot later 1031 out of OP units into another property. Other trade-offs:
- ›Taxable conversion — recognizing gain when OP units convert to shares.
- ›Loss of control — you no longer make property-level decisions.
- ›Market and interest-rate risk — REIT share values fluctuate, and rising rates can pressure valuations and distributions.
Estate Planning and the Step-Up
For investors focused on legacy, the 721 can be compelling. If OP units are held until death, heirs may receive a step-up in cost basis to fair market value, potentially eliminating the deferred gain entirely for the estate. This "defer, then step-up" outcome is a central reason many long-term holders choose the UPREIT route — though the specifics depend on current law and your estate structure.
721 vs. DST vs. Straight 1031
- ›Straight 1031 keeps you in real estate and preserves the ability to exchange again — maximum tax flexibility, but you stay concentrated (or land in another DST).
- ›Staying in DSTs offers passive, diversified real estate while keeping 1031 eligibility on the back end at each DST's sale.
- ›721 UPREIT trades that ongoing 1031 flexibility for liquidity, REIT diversification, and estate-planning advantages — a good fit when the goal is to permanently exit active real estate.
