1031 Exchange vs. 721 UPREIT Exchange

How each exchange works

A 1031 like-kind exchange swaps one investment property for another (or into a DST), deferring capital gains and depreciation recapture as long as you follow the 45-day identification and 180-day closing deadlines. A 721 exchange — often called an UPREIT — instead contributes your property into a REIT's operating partnership (the "OP") in exchange for OP units. Both defer gain at the moment of the transaction, but the 1031 keeps you in like-kind real estate, while the 721 converts your real estate into a partnership interest tied to the REIT's broader portfolio. The mechanics look similar on the surface — both let you avoid recognizing gain today — but they point in opposite directions: one keeps the deferral engine running, the other shuts it down in exchange for diversification and a liquidity path.

The mechanics of a 1031

In a 1031, you sell your relinquished property and use a qualified intermediary to hold the proceeds so you never take constructive receipt of the cash. You then have 45 days to formally identify replacement property and 180 days to close on it. The replacement can be another building you manage yourself or a passive DST interest. Do it correctly and the gain rolls into the new property; your basis carries over, and you can repeat the process as many times as you like. This is what makes the 1031 a lifetime deferral tool — there is no statutory date on which the deferred gain must be recognized.

The mechanics of a 721 UPREIT

In a 721, rather than selling for cash, you contribute the property directly into a REIT's operating partnership. In return you receive OP units, which are roughly economically equivalent to REIT shares and usually carry the same distribution rate. The contribution itself is generally tax-deferred. Later, on your own timing, you can convert OP units into tradable REIT shares — but that conversion is typically a taxable event that finally recognizes the gain you had been deferring. A frequent path is to do a 1031 into a DST first, then have that DST property contributed into the affiliated REIT via a 721 down the road.

Side-by-side snapshot

1031 like-kind exchange - Property-for-property (or into a DST) - Can be repeated indefinitely to keep deferring - You retain a real estate interest you control or co-own - Subject to 45-day ID and 180-day closing deadlines - Concentrated in specific assets; limited liquidity - Estate step-up at death can erase the deferred gain entirely

721 UPREIT exchange - Real property contributed for REIT OP units - Generally a one-time, one-way move — no further 1031s - Offers diversification across the REIT's entire portfolio - No 45/180 clock the same way — it is a contribution, not a swap - Path toward eventual liquidity by converting units to shares - Converting units to shares is generally a taxable event

The one-way nature of 721

This is the critical caveat, and it deserves repeating. Once you contribute property into a REIT through a 721 exchange and receive OP units, you generally cannot do another 1031 exchange with that interest — you have left like-kind real estate behind and now hold a partnership interest, which is not 1031-eligible. Converting OP units to REIT shares is typically a taxable event that recognizes the previously deferred gain. So a 721 trades the open-ended deferral of 1031 for the diversification and liquidity of a REIT. It is powerful, but you should treat it as a destination, not a stopover. Going in with that understanding prevents an unwelcome surprise later.

Liquidity, control, and diversification

A 1031 keeps your wealth concentrated in specific properties, which means more control but less diversification and limited liquidity. You decide when to sell, how to finance, and how to operate (or you delegate that to a DST sponsor). A 721 UPREIT spreads your interest across the REIT's entire portfolio and, over time, lets you convert OP units to shares you can sell in pieces — which can also be a useful estate-planning tool, since heirs can sell gradually. For an owner tired of managing a single asset and seeking diversification plus a liquidity path, the 721 is appealing. The cost is giving up the ability to keep exchanging and, eventually, triggering the deferred gain when units are converted and sold.

Tax treatment and timing

Both defer gain at the moment of the transaction. The difference is what comes after. With a 1031, the gain can stay deferred for your entire life, and a step-up in basis at death may wipe it out. With a 721, the gain is deferred only until you convert and sell OP units, at which point it is recognized. Holding the OP units until death may still allow a step-up for your heirs, but any units converted and sold during your lifetime generally trigger tax. Because the order of operations — and whether you ever convert — drives the result, this is a plan to map out years in advance, not at the closing table.

A worked illustration

Consider an investor holding a single building with an illustrative $400,000 deferred gain who is tired of being a landlord. Option A keeps exchanging via 1031 into a passive DST, preserving full deferral and the chance of an estate step-up, but staying in concentrated private real estate. Option B contributes the property into a REIT via a 721, instantly diversifying across the REIT's portfolio and gaining a route to liquidity — but accepting that selling shares later will recognize the $400,000. Neither is "better" in the abstract; it depends on whether the investor values continued deferral or diversification-plus-liquidity. Figures are illustrative only.

When each makes sense

Use a 1031 when you want to stay in real estate, keep deferring, and preserve the option to exchange again or pass property to heirs with a stepped-up basis. Consider a 721 UPREIT when you are ready to diversify, want a route to liquidity, and accept that this is your last deferral move. A common sequence is 1031 into a DST first, then a later 721 into the affiliated REIT. Because the order and timing carry significant tax consequences, plan the full path with your CPA and attorney before you start down it.
