1031 Exchange and Tax-Deferred Exchange

Core Mechanics

Identification window: The exchanger has 45 calendar days from the close of the relinquished-property sale to identify potential replacement properties in writing. The clock does not pause for weekends or holidays.

Exchange window: The exchanger must close on the replacement property by the earlier of 180 calendar days after the relinquished-property sale or the due date (including extensions) of the exchanger's federal tax return for the year of the sale.

Equal-or-greater-value rule: To defer 100% of the gain, the replacement property must be of equal or greater value than the relinquished property, and all of the net equity must be reinvested. If the replacement is lesser in value, the shortfall — called boot — is taxable in the year of exchange.

Qualified intermediary requirement: The exchanger may never take constructive receipt of the sale proceeds. A qualified intermediary (QI) holds the funds between the sale and the purchase. If the proceeds touch the exchanger's hands at any point, the exchange is disqualified and the full gain is recognized immediately.

Like-kind definition: Under current law, virtually all U.S. investment real property is like-kind to all other U.S. investment real property. An industrial warehouse can exchange into a multifamily property, a NNN retail strip, or a suburban office building without restriction. Personal residences and foreign property are excluded.

Exchange Structures

Delayed exchange is the most common form. The relinquished property closes first; the QI holds the proceeds; the exchanger identifies and acquires the replacement within the 45/180-day window.

Simultaneous exchange requires both legs to close on the same day. Logistically difficult for larger transactions and largely replaced in practice by the delayed structure.

Reverse exchange allows the exchanger to acquire the replacement property first, before selling the relinquished property. The replacement must be parked with an Exchange Accommodation Titleholder (EAT). The same 45/180-day window applies from the parking date. Reverse exchanges are more expensive and lender-complex.

Construction or improvement exchange allows exchange proceeds to be used for improvements to the replacement property during the 180-day window, provided the improvements are made while title is held by the EAT.

CRE Market Relevance

The 1031 exchange is a structural demand driver for income-producing CRE, not merely a tax planning tool.

Transaction-volume amplifier: A meaningful share of CRE sellers are motivated primarily by tax deferral rather than outright profit maximization. The result is sustained supply of capital looking for reinvestment under deadline pressure, regardless of whether the market is broadly active.

Pricing distortion in target asset classes: 1031 buyers operating under a 45-day identification clock are often willing to bid above what a fully discretionary buyer would pay, because the after-tax cost of overpaying is lower than the tax liability they would crystallize by letting the exchange fail. This dynamic compresses cap rates in NNN retail, net-leased industrial, and stabilized multifamily — the three asset classes most commonly targeted for 1031 replacement because of income clarity, long lease terms, and low day-to-day management burden.

NNN retail and industrial demand concentration: Single-tenant NNN assets in creditworthy locations are the canonical 1031 destination because they offer defined income streams, often with passive management, and trade at lower risk than development or value-add plays. This creates a persistent buyer pool in the NNN sector that is partly insulated from pure cap rate logic.

Delaware Statutory Trust (DST) as fractional vehicle: Exchangers who cannot identify a single suitable replacement property within 45 days, or who want passive fractional ownership, can invest in a DST — a fractional ownership structure that qualifies as like-kind real estate for 1031 purposes. DSTs have grown significantly as a mechanism for smaller and mid-market investors to deploy 1031 proceeds passively into institutional-quality assets.

The 2026 CoStar DST demand article makes the capital-formation point more current: DSTs are being used by sponsors and private-wealth platforms as replacement-property channels for owners who want tax deferral, passive income, and lower property-management burden. CoStar cited Mountain Dell Consulting for $7.34B of DST-related sales through November and a projected $7.5B of 2025 equity raises, up 33% from 2024. Treat this as trade-source demand evidence, not as a primary DST market dataset. See Source: CoStar Tax-Deferred DST Demand January 2026.

Bottleneck effect on transaction volume: In markets with tight supply and strong fundamentals — as seen in Texas retail through 2024–2025 — 1031 bottlenecks can suppress transaction volume even when sentiment is positive. Owners who cannot identify a suitable replacement are effectively locked into their current holdings. See Retail Investment Thesis 2026 for an active example.

Legislative Risk

The 1031 exchange has faced recurring legislative risk. The Biden administration's 2021 budget proposal would have capped 1031 gain deferral at $500,000 per taxpayer per year, which would have effectively eliminated the exchange incentive for most institutional and mid-market transactions. The proposal did not advance but reintroduced periodically. Any material restriction on 1031 treatment would represent a transaction-volume shock across income-producing CRE sectors, particularly NNN retail and stabilized multifamily where the 1031 buyer pool is densest.
