Understanding 721 exchanges means learning a specialized vocabulary — the terms that describe the structure, the tax treatment, the units, the process, and the strategies. This glossary gathers and explains the key 721 exchange and UPREIT terms, organized by theme: the core 721 terms, the UPREIT structure terms, the tax terms, the OP unit and liquidity terms, the process terms, and the DST bridge terms. Whether you're new to 721 exchanges or want to solidify your understanding, this glossary helps you grasp the language and concepts. Each term is defined clearly, with context for how it fits into the 721 exchange world. This guide is a comprehensive glossary of 721 exchange terms, organized to build your understanding from the foundations through the advanced concepts.
Core 721 terms
The core 721 terms describe the fundamental concept. A 721 exchange (also called an UPREIT conversion) is the contribution of real estate to a REIT's operating partnership in exchange for partnership units, tax-deferred under Section 721. Section 721 is the Internal Revenue Code section providing that no gain or loss is recognized when property is contributed to a partnership for a partnership interest — the legal basis for the deferral.
An UPREIT (umbrella partnership real estate investment trust) is a REIT that owns its properties through an operating partnership, enabling tax-deferred 721 contributions. The contribution is the act of transferring your property to the operating partnership for units. Tax deferral is the postponement of the capital gains tax that the 721 exchange achieves.
These core terms — 721 exchange, Section 721, UPREIT, contribution, tax deferral — are the foundation of the 721 exchange vocabulary. Understanding them establishes the basic concept: contributing real estate to a REIT's operating partnership for units, tax-deferred. The core 721 terms — 721 exchange (UPREIT conversion), Section 721 (the deferral provision), UPREIT (the enabling structure), contribution (the transfer), and tax deferral (the benefit) — are the foundation of the vocabulary. They establish the basic concept. Understanding the core terms is the starting point. The core 721 terms define the fundamental concept of contributing real estate to a REIT's operating partnership for units, tax-deferred under Section 721.
UPREIT structure terms
The UPREIT structure terms describe how the REIT is organized. The operating partnership (OP) is the partnership beneath the REIT that directly owns and operates the real estate — the entity you contribute your property to and receive units in. The REIT is the parent entity (often publicly traded) that controls the operating partnership (as general partner) and is owned by shareholders.
The general partner is the controlling partner of the operating partnership (the REIT), which manages it. The limited partners are the non-controlling partners (including you, as a unit holder) with economic interests but not control. A DownREIT is a variation using separate lower-tier partnerships for contributed property (rather than one umbrella operating partnership), more complex than a standard UPREIT.
These structure terms — operating partnership, REIT, general partner, limited partner, DownREIT — describe the UPREIT's organization (the REIT over the operating partnership over the real estate, with you as a limited partner). Understanding them clarifies the structure you're entering. The UPREIT structure terms — operating partnership (the property-owning partnership), REIT (the controlling parent), general partner (the REIT, controlling), limited partner (you, the unit holder), and DownREIT (the multi-partnership variation) — describe the structure. They clarify the organization. Understanding the structure terms shows how the UPREIT is organized. The UPREIT structure terms describe the REIT-over-operating-partnership organization you enter, with you as a limited partner holding units.
Learn the structure: the REIT (parent, general partner) sits over the operating partnership (which owns the real estate), and you become a limited partner holding OP units — the hierarchy at the heart of every 721 exchange.
Tax terms
The tax terms describe the 721 exchange's tax mechanics. Carryover basis is your property's basis carrying into the OP units, embedding the deferred gain (the difference between the units' value and your low basis). The deferred gain is the gain you don't recognize at contribution (carried in the units). The step-up in basis at death is the reset of your heirs' basis to fair market value, which can erase the deferred gain.
Depreciation recapture is the tax (up to 25%) on prior depreciation, deferred by the 721 (carried in the units) and triggered on conversion. The four-layer tax stack is the combined tax (capital gains, recapture, NIIT, state) the 721 defers. A tax protection agreement is the agreement protecting your deferred gain from being triggered by a partnership sale. Built-in gain is the deferred gain associated with your contributed property.
These tax terms — carryover basis, deferred gain, step-up, depreciation recapture, four-layer tax stack, tax protection agreement, built-in gain — describe the tax mechanics and benefits. Understanding them clarifies how the 721 defers (and potentially eliminates) the tax. The tax terms — carryover basis, deferred gain, step-up in basis, depreciation recapture, the four-layer tax stack, tax protection agreement, and built-in gain — describe the tax mechanics. They clarify the deferral and benefits. Understanding the tax terms shows how the 721 works tax-wise. The tax terms describe how the 721 exchange defers the gain (carryover basis), preserves it (deferred/built-in gain), and can eliminate it (the step-up), with the tax protection agreement safeguarding the deferral.
OP unit and liquidity terms
The OP unit and liquidity terms describe what you hold and how you access value. OP units (operating partnership units) are your ownership interest in the operating partnership, received in the 721 exchange — paying distributions and convertible to REIT shares. REIT shares are the corporate, often-traded ownership of the REIT, which OP units convert into. Distributions are the income paid on OP units (comparable to REIT dividends).
Conversion is exchanging OP units for REIT shares (after a lock-up), which triggers the deferred gain (taxable). The lock-up period (or holding period) is the time before you can convert units to shares (often around a year). A redemption program is a non-traded REIT's mechanism for buying back shares (the non-traded liquidity path). The Schedule K-1 is the partnership tax form reporting your share of the partnership's income.
These terms — OP units, REIT shares, distributions, conversion, lock-up period, redemption program, Schedule K-1 — describe your holding (OP units), its income (distributions), and your liquidity (conversion, redemption). Understanding them clarifies what you hold and how to access value. The OP unit and liquidity terms — OP units (your holding), REIT shares (what you convert into), distributions (the income), conversion (the taxable liquidity step), lock-up period (the initial wait), redemption program (non-traded liquidity), and Schedule K-1 (the tax form) — describe your holding and liquidity. They clarify what you hold. Understanding these terms shows your ownership and liquidity. The OP unit and liquidity terms describe what you hold (OP units), its income (distributions), and how to access value (conversion, redemption, with the lock-up and K-1).
Process and party terms
The process and party terms describe the transaction and the participants. The contribution agreement is the document effecting the 721 exchange (your property for units). The valuation is the determination of your property's value (setting your units). The suitability review is the assessment of whether the 721 exchange fits your circumstances (required since it involves securities). An accredited investor is one meeting income or net-worth thresholds, typically required for the securities involved.
The sponsor is the firm behind the REIT (or DST). The CPA handles the tax aspects; the attorney handles the legal structuring and documents; the financial advisor (through a broker-dealer) handles the suitability and securities. These professionals make up your 721 exchange team.
These process and party terms — contribution agreement, valuation, suitability review, accredited investor, sponsor, and the professional team (CPA, attorney, advisor) — describe the transaction and participants. Understanding them clarifies the process and who's involved. The process and party terms — contribution agreement, valuation, suitability review, accredited investor, sponsor, and the professional team — describe the transaction and participants. They clarify the process. Understanding these terms shows how the exchange is executed and by whom. The process and party terms describe the 721 exchange transaction (contribution agreement, valuation, suitability) and the participants (sponsor, CPA, attorney, advisor).
- Core terms: 721 exchange (UPREIT conversion), Section 721, UPREIT, contribution, tax deferral.
- Structure terms: operating partnership, REIT, general/limited partner, DownREIT.
- Tax terms: carryover basis, deferred gain, step-up, depreciation recapture, tax protection agreement, built-in gain.
- OP unit/liquidity terms: OP units, REIT shares, distributions, conversion, lock-up period, redemption program, Schedule K-1; plus process terms and the DST bridge.
The DST bridge terms
The DST bridge terms describe the common path to reaching a REIT. A Delaware Statutory Trust (DST) is a 1031-eligible passive real estate vehicle used as a bridge to a REIT. The DST bridge (or 1031-then-721) is the two-step strategy of doing a 1031 exchange into a DST, then a 721 exchange into a REIT. The 721 exit (or UPREIT exit) is the REIT acquiring the DST's property and converting your interest into OP units.
The step-transaction doctrine is the IRS principle that can collapse the bridge's steps if they're too integrated (requiring genuine, independent steps). Continuous deferral is the gain being deferred across both steps (Section 1031 then Section 721). These terms describe the bridge strategy and its considerations.
Understanding the DST bridge terms — DST, DST bridge / 1031-then-721, 721 exit, step-transaction doctrine, continuous deferral — clarifies the common path to REIT ownership and its tax considerations. The DST bridge terms — Delaware Statutory Trust (DST), the DST bridge (1031-then-721), the 721 exit, the step-transaction doctrine, and continuous deferral — describe the path to reaching a REIT and its considerations. They clarify the bridge strategy. Understanding these terms completes the vocabulary. The DST bridge terms describe the common two-step path (1031 into a DST, then 721 into a REIT) and its key consideration (the step-transaction doctrine), completing the 721 exchange vocabulary.

Frequently Asked Questions
What is a 721 exchange?
The contribution of real estate to a REIT's operating partnership in exchange for partnership units (OP units), tax-deferred under Section 721. Also called an UPREIT conversion. It transitions you from direct property ownership into REIT ownership (the OP units), deferring the capital gains tax, while gaining diversification, passivity, liquidity (via convertible units), and estate benefits. It's a foundational term — the strategy of converting property into REIT units tax-deferred, which the rest of the vocabulary describes.
What is Section 721?
The Internal Revenue Code section providing that no gain or loss is recognized when property is contributed to a partnership in exchange for a partnership interest — the legal basis for the 721 exchange's tax deferral. So Section 721 is why contributing your property to the REIT's operating partnership for OP units is tax-deferred. The '721 exchange' is named for this code section. It's the foundational tax provision enabling the strategy.
What is an UPREIT?
An umbrella partnership real estate investment trust — a REIT that owns its properties through an operating partnership (rather than directly), enabling tax-deferred 721 contributions. The structure (the REIT over the operating partnership over the real estate) is what allows property owners to contribute property for units tax-deferred. Most REITs that accept 721 contributions are UPREITs. So the UPREIT is the structure that makes the 721 exchange possible — the framework you transition into.
What are OP units?
Operating partnership units — your ownership interest in the REIT's operating partnership, received in a 721 exchange. They pay distributions (comparable to REIT dividends), represent your stake in the REIT's portfolio, and are convertible into REIT shares (after a lock-up). OP units are what you hold after a 721 exchange — your tax-deferred REIT ownership. They're the form your real estate wealth takes in the strategy, central to the vocabulary.
What is carryover basis?
Your property's tax basis carrying into the OP units, embedding the deferred gain. When you contribute your property, your low basis carries over to become your basis in the OP units, so the deferred gain (the difference between the units' value and your low basis) is preserved in the units. The carryover basis is the mechanism that defers (rather than forgives) the gain, carrying it into your units to be recognized later (or erased by the step-up). It's a key tax term.
What is the step-up in basis?
The reset of your heirs' basis in the OP units to fair market value at your death, which can erase the deferred gain. If you hold the units until death, your heirs inherit them with a stepped-up basis, eliminating the embedded deferred gain (so they can convert or sell with little income tax on the prior appreciation). The step-up is the powerful estate benefit that can turn the 721's deferral into permanent elimination of the gain. It's a central tax and estate term.
What is conversion?
Exchanging your OP units for REIT shares (after the lock-up period), which provides liquidity (for a traded REIT, the shares are tradable) but triggers the deferred gain (a taxable event). So conversion is the step from OP units to REIT shares, your path to liquidity, with the tax cost of recognizing the deferred gain. Many investors convert gradually (tax-smartly) for liquidity or hold the units (deferring) toward the step-up. Conversion is a key liquidity and tax term.
What is the lock-up period?
The time after receiving your OP units during which you can't yet convert them to REIT shares (often around a year, varying by REIT). During the lock-up, you hold the units (earning distributions, deferring) but can't convert. After the lock-up, the conversion (and thus liquidity) becomes available. The lock-up is the initial holding requirement before you can access the conversion-to-shares liquidity. It's a process and liquidity term to understand for planning.
What is the DST bridge?
The two-step strategy (also called 1031-then-721) of doing a 1031 exchange into a Delaware Statutory Trust (DST), then a 721 exchange into a REIT — reaching REIT ownership tax-deferred from direct property. Since you can't 1031 directly into a REIT, the DST (which is 1031-eligible) bridges the gap, later being acquired by a REIT (the 721 exit). The DST bridge is the common practical path to REIT ownership, and an important term for understanding how most investors reach a 721 exchange.
How does Baker 1031 help me understand the terms?
We help you understand the 721 exchange vocabulary and concepts — explaining the terms (core, structure, tax, OP units/liquidity, process, DST bridge) in plain language, so you can grasp the strategy and make informed decisions. We help you learn the language from the foundations through the advanced concepts. REIT units and DST interests are offered through the broker-dealer (Aurora Securities, member FINRA/SIPC) after a suitability review. We help you understand the terms and how they apply to your situation, so you can engage with the strategy knowledgeably and make informed decisions. Understanding the vocabulary is the foundation of an informed decision.
What is the operating partnership?
The partnership beneath the REIT in an UPREIT structure that directly owns and operates the real estate. When you do a 721 exchange, you contribute your property to this operating partnership and receive OP units in it, becoming a limited partner. The REIT controls the operating partnership (as general partner). So the operating partnership is the entity you transition into — it holds the REIT's real estate, and your OP units represent your stake in it. It's the key structural component of the UPREIT and the entity central to the 721 exchange.
What are distributions?
The income paid on your OP units, comparable to the dividends the REIT pays its shareholders, reflecting your share of the income from the REIT's portfolio. So as an OP unit holder, you receive distributions — passive income from the REIT's real estate, without management work. The distributions are your ongoing income from the 721 exchange while you hold the units, taxed under partnership rules (via the K-1). They're a key benefit of OP unit ownership — regular passive income from diversified real estate. Distributions are how your OP units pay you while you hold them.
What is a tax protection agreement?
An agreement negotiated in the 721 exchange in which the REIT/operating partnership agrees to protect your deferred (built-in) gain from being triggered if the partnership sells your contributed property in a taxable way — typically by agreeing not to sell it taxably for a period, or compensating you if it does. So the tax protection agreement safeguards the security of your deferral against a premature triggering by a partnership sale. It's an important term to negotiate, since it protects your tax deferral. The agreement's terms (the protected period, the form of protection) determine how well your deferred gain is safeguarded.
What is the 721 exit (or UPREIT exit)?
The step in the DST bridge where the REIT acquires the DST's property and converts the DST investors' interests into REIT OP units, completing the transition into REIT ownership. So in the 1031-then-721 path, after you 1031 into a DST, the '721 exit' (or 'UPREIT exit') is when the DST is acquired by the REIT and you receive OP units (under Section 721). It's the second step of the DST bridge, reaching the REIT. The 721 exit's timing isn't always guaranteed (it depends on the DST/REIT structure), so understanding the expected exit is part of the DST bridge.
What is a DownREIT?
A REIT structure variation that uses separate lower-tier partnerships for contributed property, rather than one umbrella operating partnership (the standard UPREIT). In a DownREIT, the REIT owns properties at multiple levels, and contributed property goes into a specific lower-tier partnership (with you holding units in it). It's more complex than a standard UPREIT and used in specific circumstances (e.g., a non-UPREIT REIT accepting a contribution). Both UPREITs and DownREITs allow tax-deferred 721 contributions, but the DownREIT's multi-partnership structure is more complex. It's a less common but important term in the vocabulary.
What is the four-layer tax stack?
The combined tax that selling appreciated real estate would trigger, which the 721 exchange defers: federal capital gains tax (up to 20%), depreciation recapture (up to 25%), the 3.8% net investment income tax (NIIT), and state income tax. Together these often total a third or more of the gain. The 721 exchange defers all four layers. So the 'four-layer tax stack' is shorthand for the full tax burden of a sale, which the 721 exchange (like the 1031) postpones. Understanding it shows the magnitude of what the 721 exchange defers — not just capital gains, but recapture, NIIT, and state tax too.
What is an accredited investor?
An investor who meets certain income or net-worth thresholds defined by securities regulations (e.g., income above a specified level, or net worth above a specified level excluding a primary residence), typically required to access the securities offerings involved in a 721 exchange (OP units, DSTs, REIT interests). So accreditation is generally a prerequisite for the securities-based 721 exchange paths. Most owners of substantial appreciated real estate meet the thresholds. Your financial professional verifies your accreditation. It's a key term because the 721 exchange's securities are typically limited to accredited investors.
What is a suitability review?
The assessment by a financial professional (through a broker-dealer) of whether the 721 exchange (and the specific offering) is appropriate for your financial situation, objectives, risk tolerance, time horizon, and liquidity needs — required because the 721 exchange involves securities. It ensures the strategy is recommended only when it fits your circumstances, protecting you from an unsuitable recommendation. So the suitability review is a substantive part of the 721 exchange process, assessing fit. It's an important term because every securities-based 721 exchange involves a suitability review confirming the strategy suits you before it's recommended.
