Improvement Exchanges: Timing Traps Advisors Rarely See Coming

When a Like-Kind Swap Isn't Enough

Most 1031 exchange conversations center on swapping one property for another of equal or greater value. But what happens when a client identifies replacement property that needs significant work before it meets their investment criteria — or when they want to deploy relinquished-property equity into a ground-up build on land they already control?

That's where improvement exchanges, sometimes called construction or build-to-suit exchanges, enter the picture. These structures allow taxpayers to use exchange proceeds to fund improvements on the replacement property before taking title, effectively treating constructed improvements as part of the like-kind replacement. Used correctly, they're a legitimate and powerful planning tool. Used carelessly, they collapse — and the IRS collects.

This article focuses on the timing and structural traps that catch advisors off guard, particularly when clients are coordinating large capital projects alongside a sale.

The Core Legal Framework

Improvement exchanges operate under the same statutory foundation as all deferred exchanges: Section 1031 of the Internal Revenue Code. The critical overlay is Revenue Procedure 2000-37, which established the Exchange Accommodation Titleholder (EAT) structure — the mechanism that makes improvement exchanges legally workable.

Here's the fundamental problem improvement exchanges solve: a taxpayer cannot receive or control replacement property before the exchange is complete, yet improvements must be made on property. The EAT — typically a single-purpose LLC affiliated with the qualified intermediary — holds title to the replacement property during the construction period. The taxpayer never takes title until improvements are substantially complete, preserving the exchange's tax-deferred status.

Two deadlines govern the entire transaction:

• 45-day identification window: The taxpayer must identify replacement property within 45 days of closing on the relinquished property.
• 180-day exchange period: The taxpayer must receive the replacement property — improved and titled — within 180 days of the relinquished property closing.

Both deadlines are absolute. There are no extensions for construction delays, permit backlogs, contractor disputes, or weather events. The 180-day clock does not care about your client's general contractor.

The Timing Trap Most Advisors Underestimate

Here's where wealth advisors routinely get into trouble: they treat 180 days as a comfortable runway. It isn't.

Consider what must happen within that window: the EAT acquires the replacement property, exchange funds flow to the EAT, construction contracts are executed, permitting is obtained (where required), improvements are completed, and then title transfers to the taxpayer. In many markets and for many project types, 180 days is extremely tight — and any delay in the relinquished property closing that pushes the exchange start date later only compounds the pressure.

The practical implication is that improvement exchanges demand pre-sale construction planning. By the time your client closes on the relinquished property, the following should already be in place or near-final:

• Replacement property under contract or identified
• Construction scope and budget documented
• Contractor selected and contract terms negotiated
• Permitting timeline assessed with local counsel
• EAT structure confirmed with the QI

Advisors who introduce improvement exchanges as an option after the relinquished property is listed — let alone after closing — are setting their clients up for a failed exchange.

What Counts as a Qualifying Improvement

Not every dollar spent on a property during the exchange period qualifies as like-kind replacement value. The IRS requires that improvements be completed and on the property when title transfers to the taxpayer. Improvements that are contracted but unfinished, or funds that are committed but unspent, do not count toward satisfying the exchange value requirement.

This matters enormously for equity deployment. If a client relinquishes a property for $3 million and the replacement land plus planned improvements are valued at $3.2 million, but only $2.6 million in improvements are complete at the 180-day mark, the taxpayer receives property worth $2.6 million (plus land). The remaining exchange proceeds may be treated as boot — taxable cash received in the exchange — unless carefully restructured.

Advisors should also note that land itself is not depreciable. One of the primary financial benefits of an improvement exchange is the depreciation reset on new construction — but that benefit accrues only on the improvements, not on land value. Modeling the after-tax economics requires separating these components carefully.

EAT Selection and QI Coordination

Because the EAT holds legal title during construction, its creditworthiness, legal structure, and relationship with the QI are not administrative details — they are substantive deal risks. Advisors should ask the following before recommending an improvement exchange structure:

1. Who serves as EAT, and are they properly capitalized? An undercapitalized or improperly structured EAT can create agency or alter-ego arguments that unwind the exchange.
2. How are construction funds held and disbursed? Exchange proceeds should flow through the QI's qualified escrow or trust account, with disbursements to contractors managed transparently. Co-mingling risks are real.
3. What happens if improvements aren't complete at 180 days? The answer should be documented in the exchange agreement, not improvised. Some QIs offer partial exchange completion structures; others do not.
4. Is the QI experienced with EAT transactions specifically? Improvement exchanges require a higher level of operational sophistication than standard deferred exchanges. Not every QI handles them well.

The Strategic Opportunity Worth the Complexity

Despite the operational demands, improvement exchanges serve a real planning need. Clients with concentrated real estate equity and a vision for a specific asset type — a net-lease build-to-suit, a mixed-use ground-up, a value-add repositioning — often cannot find suitable replacement inventory in the open market. An improvement exchange lets them deploy capital precisely, reset depreciation on new construction, and maintain tax deferral simultaneously.

For family offices and high-net-worth investors with patient, organized advisors, the complexity is manageable. The key is engaging qualified intermediaries with genuine EAT experience, beginning construction planning well before the relinquished property closes, and modeling the full timeline conservatively — with buffer for the delays that almost always occur.

The 180-day clock is unforgiving. But advisors who build their process around that reality, rather than against it, can deliver real value through improvement exchange strategies.
