Section 721 Exchange Rules: Eligibility, Contributions, and OP Units

Written by The Realized Team | Nov 2, 2026

A Section 721 exchange generally allows an investment property owner to contribute qualifying real estate to a REIT’s operating partnership in exchange for OP units without immediate recognition of gain. The core rules center on whether the REIT wants the property, how the contribution is structured, and when later actions—such as conversion to shares or cash—trigger taxes.

Who May Be Eligible

Section 721 exchanges are typically used by owners of appreciated investment or commercial real estate who want to stop direct property management while deferring capital gains taxes. In practice, eligibility is not just about the property owner. The receiving REIT or its operating partnership must also agree to accept the property.

That means a workable transaction usually depends on two questions:

• Does the owner hold appreciated investment real estate suitable for contribution?

• Does the REIT view that asset as a fit for its portfolio strategy?

A 721 transaction is not automatic. The REIT sponsor can reject a property if it does not meet valuation, quality, location, or portfolio objectives. Property owners should also remember that once they receive OP units, they have exchanged into a security and no longer own direct real estate.

What Can Be Contributed

The contribution is generally the real estate itself, transferred into the REIT’s operating partnership rather than sold for cash. In return, the owner receives operating partnership units, commonly called OP units, based on the agreed value of the contributed property.

Important contribution points include:

• Property fit: The REIT must want the asset and believe it supports its investment strategy.

• Valuation: The number of OP units issued depends on the property’s agreed or appraised value.

• Structure: The transfer is treated as a contribution to a partnership, not a traditional sale.

Some investors reach a 721 transaction after first completing a 1031 exchange into property the REIT has identified, then contributing that replacement property after a holding period. But the central rule is the same: the tax deferral depends on a contribution of property, not a cash sale.

How OP Units Work

OP units represent an ownership interest in the operating partnership that sits under the REIT. Their value generally tracks the underlying REIT, and holders may receive distributions tied to partnership income.

Key features of OP units include:

• Tax deferral: Receiving OP units at contribution generally does not trigger immediate capital gains recognition.

• Income potential: Holders may receive distributions while they own the units.

• Conversion rights: OP units may later be converted into REIT shares or redeemed for cash, subject to the partnership agreement.

• Restrictions: Many agreements impose a lock-up or holding period before conversion is allowed.

• Control limits: OP unit holders generally do not have the same voting rights as REIT shareholders.

For many property owners, the tradeoff is simple: less direct control in exchange for professional management, potential diversification, and a different path to liquidity.

What Triggers Taxes Later

The 721 exchange is a deferral strategy, not a tax elimination strategy. Future tax recognition may occur when:

• You convert OP units into REIT shares

• You redeem or sell OP units for cash

• The contributed property is sold in a way that creates recognition under the governing structure

That makes pre-transaction planning important. A 721 exchange can be useful, but investors should review the partnership agreement, holding restrictions, distribution terms, and tax consequences with qualified legal and tax advisors before moving forward.

Frequently Asked Questions

Can I do a 1031 exchange after I receive OP units?

Usually no. Once you receive OP units in a Section 721 transaction, you no longer own direct real estate. You own an interest in an operating partnership, which is a security, so those units generally cannot be exchanged later through another 1031 exchange into replacement real estate.

Do I owe taxes when I receive OP units?

Generally, receiving OP units in exchange for contributing qualifying property does not create immediate gain recognition. The tax issue usually arises later if you convert the OP units into REIT shares, redeem them for cash, or otherwise dispose of the interest in a taxable transaction.

Can I sell my OP units whenever I want?

Not necessarily. Many Section 721 transactions include lock-up periods or other transfer restrictions that limit when OP units can be converted into REIT shares or redeemed for cash. The timing, rights, and limitations depend on the specific partnership agreement and the REIT sponsor’s terms.
