1031 vs 721 — Trading Deferral Paths Into a REIT

Two deferral sections, two destinations: 1031 keeps you in direct real estate; 721 converts property into operating-partnership units of a REIT — liquid-ish, diversified, and permanently outside the exchange system. Most investors meet 721 at the end of a DST hold, when the sponsor offers the “UPREIT” path.

How 721 works

Contribute property (or your DST interest, once the trust’s property is absorbed) to a REIT’s operating partnership in exchange for OP units — tax-deferred under Section 721, no QI, no deadlines. Units mirror REIT share economics (distributions, value tracking) and typically convert 1:1 into REIT shares whenever you choose. The catch is in the conversion: exchanging units for shares — or the REIT selling your contributed property — recognizes the deferred gain. And OP units can never 1031 again; entering the REIT is exiting the exchange ecosystem.

The comparison that matters

1031 preserves optionality: keep exchanging, keep control, ride toward the step-up at death — which OP units also reach, notably, if you hold them to the end. 721 buys diversification and quasi-liquidity at the price of that optionality: no more property-level decisions, distributions set by REIT policy, and gain recognition triggerable by the REIT’s own portfolio moves. Fees and valuation terms on the contribution deserve real scrutiny — the exchange ratio is the price you’re selling at, whether or not tax is due that day.

Who chooses which

Owners who want to stay owners — the readers of this site’s tenant and state pages — remain 1031 people. 721 fits the final chapter: aging holders wanting REIT diversification without a taxable sale, DST investors at trust exit, estates preferring unit liquidity for heirs. It’s a fine last move precisely because it’s designed to be last.
