Build Before You Buy: Mastering Improvement Exchanges for HNW Clients

When a Standard 1031 Exchange Isn't Enough

Most wealth advisors are comfortable steering clients through a standard forward 1031 exchange — sell the relinquished property, engage a qualified intermediary, identify a replacement property within 45 days, close within 180 days. Clean and straightforward. But high-net-worth clients rarely operate in the straightforward lane.

Consider a client who sells a $4 million industrial building and wants to roll the proceeds into a raw commercial lot — then construct a custom logistics facility on it. Or a family office that needs to acquire an aging multifamily asset and gut-renovate it before taking title. These scenarios call for an improvement exchange (sometimes called a construction exchange or build-to-suit exchange), a powerful but procedurally demanding variant of Section 1031 that every serious wealth advisor should understand.

What Is an Improvement Exchange — and Why the IRS Cares

Under Section 1031 of the Internal Revenue Code, a taxpayer can defer capital gains taxes by exchanging like-kind real property held for investment or productive use in a trade or business. The challenge with new construction is that you cannot simply receive a vacant lot, build on it at your leisure, and claim that the finished building qualifies as your replacement property. The IRS is clear: the replacement property must be identified and received within the standard exchange deadlines, and it must be of equal or greater value than the relinquished property to fully defer gain.

If a client takes title to bare land and then builds improvements, the construction costs incurred after title transfer do not count toward the replacement property value for exchange purposes. This is the core problem improvement exchanges solve — and the reason they require a carefully structured arrangement with a qualified intermediary.

The Exchange Accommodation Titleholder: The Mechanism That Makes It Work

The legal backbone of an improvement exchange is the Exchange Accommodation Titleholder (EAT), a concept formalized in IRS Revenue Procedure 2000-37. The EAT — typically an LLC set up and managed by the qualified intermediary — takes title to the replacement property on the client's behalf. While the EAT holds title, construction or renovation proceeds using the exchange proceeds. Once the improvements are substantially complete, title transfers to the taxpayer as the replacement property in the exchange.

This structure allows construction costs to count toward the replacement property's value, solving the core problem. But the procedural guardrails are strict:

• The 180-day clock still applies. The entire exchange — including construction and title transfer — must be completed within 180 days of the sale of the relinquished property. There are no extensions for construction delays, permitting holdups, or contractor issues.
• The 45-day identification rule still applies. The taxpayer must formally identify the replacement property (including the land and the intended improvements) within 45 days of closing the relinquished property sale.
• Improvements must be completed before transfer. Only improvements completed before the EAT transfers title to the taxpayer count toward the replacement property value. Unfinished improvements may constitute boot, triggering partial recognition of gain.
• The EAT must be treated as the true owner. The arrangement must respect the EAT's legal ownership during the construction period. The taxpayer cannot control the property or act as if they already own it.

Practical Challenges Wealth Advisors Should Flag Early

Improvement exchanges are not a workaround you can retrofit at the last minute. They demand early planning, experienced QI partners, and realistic project timelines. Here are the pressure points advisors need to surface with clients before the relinquished property closes:

Timeline Compression Is the Biggest Risk

One hundred eighty days sounds like a comfortable runway until you factor in environmental due diligence, permitting, contractor procurement, and the inevitable construction surprises. Advisors should require clients to have a construction timeline in hand — with contingency built in — before the exchange begins. If there is any reasonable chance improvements won't be substantially complete within 180 days, the improvement exchange structure may not be appropriate, and alternatives like a Delaware Statutory Trust (DST) or a simpler like-kind property should be considered.

Identification Must Be Specific and Comprehensive

The 45-day identification notice for an improvement exchange must describe not only the land or property being acquired but also the improvements to be constructed. Vague descriptions create IRS exposure. Work with the QI to ensure the identification language is precise and aligns with the construction plans and budget.

QI Fees and EAT Costs Add Up

The EAT structure involves additional legal and administrative costs compared to a standard exchange — entity formation, title holding fees, and sometimes financing arrangements if the client needs bridge capital to fund construction before exchange proceeds are deployed. Model these costs into the client's net benefit analysis early.

Lender Cooperation Is Not Guaranteed

If the client needs construction financing, lenders must be willing to lend to the EAT entity rather than the taxpayer. Not all lenders are familiar or comfortable with this structure. Engage a lender experienced in 1031 improvement exchanges before the relinquished property closes.

The Advisor's Role: Orchestrator, Not Spectator

Improvement exchanges illustrate why wealth advisors cannot treat 1031 transactions as a task to hand off entirely to a QI and step back. The advisor's role is to orchestrate the full professional team — the QI, tax counsel, real estate attorney, contractor, and lender — and ensure every party understands the non-negotiable IRS deadlines.

For clients who want to use exchange proceeds to create a truly customized asset — a purpose-built facility, a renovated mixed-use property, a ground-up development — the improvement exchange is one of the most powerful tools in the deferral toolkit. It just demands the same discipline and attention to detail that your clients apply to every other aspect of their portfolios.
