A 721 UPREIT exchange, often called a 721 exchange or informally a death swap among practitioners, is a two-step sequence. First, an investor completes a Section 1031 exchange into a Delaware statutory trust interest that a particular REIT has agreed to acquire later. Second, after a required holding period, the investor contributes that DST interest to the REIT's operating partnership under Section 721, receiving units in the operating partnership in exchange. Those units are typically convertible into REIT shares or cash at the REIT's option.
The name comes from Internal Revenue Code Section 721, which allows property to be contributed to a partnership without immediate gain recognition, distinct from and in addition to the Section 1031 exchange that got the investor into the DST in the first place. It is not a way to exchange directly into REIT shares; the DST step is what makes the transaction eligible for 1031 treatment in the first place.
While the investor holds the DST interest, they own a fractional interest in real property, illiquid but still real estate for tax purposes. Once that interest converts into operating partnership units, the investor holds a security, an interest in a partnership that itself owns a large, diversified pool of properties across the REIT's portfolio, rather than a fractional stake in a single asset. That diversification is often the appeal, spreading concentration risk across dozens or hundreds of properties instead of the two or three the DST held.
The 721 contribution itself is generally not a taxable event, since Section 721 defers gain on property contributed to a partnership in exchange for a partnership interest. But the investor has now exited the 1031 exchange chain entirely. If the operating partnership units are later converted to REIT shares or redeemed for cash, that conversion is typically a taxable event, and no further exchange into another 1031-eligible property is possible from that point forward.
The practical reason investors accept this conversion is liquidity and estate simplicity. DST interests generally cannot be sold on any secondary market and are illiquid until the DST itself sells its property, often on a schedule set entirely by the sponsor. Operating partnership units, once converted to REIT shares in a publicly traded REIT, can be sold on the open market. For an aging investor who no longer wants to keep exchanging into new real estate every few years just to defer tax, ending the exchange chain at the 721 step and holding tradeable REIT shares, or units that convert on demand, can be the more livable outcome.
The cost of that liquidity is giving up the step-up in basis benefit that comes from holding real property, or a DST interest, until death. Heirs who inherit real property, including a DST interest, typically receive a stepped-up basis that can eliminate the deferred gain entirely. Heirs who inherit REIT shares received through a 721 contribution do not get that same real-property basis step-up on the built-in gain that was deferred through the exchange chain; the specific tax treatment depends on how the operating partnership agreement and any redemption were structured, and it needs review with a tax professional before the 721 step, not after.
REIT sponsors that offer this pathway typically require the DST interest to be held for a minimum period, often one to two years, before contribution to the operating partnership is available. The IRS has generally respected such holding periods as evidence that the DST interest was acquired for investment rather than as a disguised sale to the REIT dressed up as a 1031 exchange. An investor who tries to move too quickly from the original property sale through the DST and into operating partnership units risks the entire chain being recharacterized as a taxable sale from the start.
Not every DST offering includes a 721 UPREIT contribution option. This is a feature specific to certain sponsor programs affiliated with a REIT, and it should be confirmed in the DST's private placement memorandum before an investor selects that DST specifically because a future 721 exit is expected to be available.
Both the DST interest and the operating partnership units are securities, not direct real estate, and both are typically offered only to accredited investors through a private placement. Suitability review at each step, the DST purchase and the later 721 contribution, is controlled by the offering documents and by a registered representative or investment adviser, not by general educational material. An investor's tolerance for illiquidity, concentration in a single REIT's portfolio and management, and loss of further 1031 eligibility should all be weighed against the estate and diversification benefits before committing to either step.
Fees layer at both stages as well, DST acquisition and disposition fees at the first step, and often additional structuring costs at the 721 contribution, which should be disclosed in the respective offering documents and compared against the liquidity benefit being purchased.
Not every DST holder needs to take the 721 step. An investor content to remain in the exchange chain, deferring gain through repeated exchanges as each DST eventually sells its property, can keep doing so indefinitely without ever contributing to an operating partnership, preserving the real-property basis step-up for heirs the entire time. The 721 pathway is a deliberate exit from that chain in exchange for liquidity and diversification, and investors who are unsure which they want should treat the 721 contribution as effectively irreversible once made, since operating partnership units cannot convert back into 1031-eligible real property.
Reviewing this decision with both a tax professional and the securities-licensed representative managing the DST holding, well before any offered 721 window closes, avoids a rushed choice driven by a sponsor's timeline rather than the investor's own planning horizon.
