IMPROVEMENT BUILD-TO-SUIT EXCHANGE

An improvement exchange, sometimes called a build-to-suit exchange or a construction exchange, lets an investor use 1031 exchange proceeds not only to acquire replacement property, but also to fund improvements to that property before it is deeded back into the taxpayer's own name. This structure is useful when the ideal replacement property does not exist yet in finished form, or when the relinquished property sale generates more proceeds than a comparable finished property would cost, leaving room to fund renovations, expansions, or ground-up construction using exchange dollars rather than after-tax cash.

Like a reverse exchange, an improvement exchange relies on the exchange accommodation titleholder safe harbor established in Revenue Procedure 2000-37, because a taxpayer cannot directly own a property and simultaneously treat improvements made to that same property as part of a tax-deferred exchange. Instead, the exchange accommodation titleholder takes and holds title to the replacement property for the duration of the improvement period, using exchange proceeds, released by the qualified intermediary, to fund construction draws while the taxpayer coordinates the design and building process.

Why the one hundred eighty-day deadline drives the construction schedule

The value of the replacement property for exchange purposes is measured at the moment title transfers from the exchange accommodation titleholder back to the taxpayer, which must happen no later than the one hundred eighty-day exchange deadline. Only improvements that are actually in place, and that have increased the property's value, by the time that transfer occurs count toward satisfying the exchange. Improvements completed after the taxpayer takes title do not retroactively count, even if they were planned from the outset and funded from the same construction budget. This means the construction or renovation schedule has to be built around the one hundred eighty-day deadline from day one, with realistic allowances for permitting delays, weather, and subcontractor scheduling, particularly for ground-up construction in Greater Boston, where permitting and inspection timelines can extend a project well beyond initial estimates.

Because full ground-up construction rarely finishes within a six-month window, many improvement exchanges are structured around smaller-scope renovations, tenant improvements, or partially completed vertical construction where a meaningful, appraisable increase in value can be documented by the one hundred eighty-day deadline, even if the project is not fully finished. Getting a realistic construction timeline from a contractor before committing exchange proceeds to a build-to-suit structure is one of the most important steps in avoiding a mismatch between the construction schedule and the exchange deadline.

Fund control and contractor draws

Because the taxpayer cannot have actual or constructive receipt of exchange funds, construction draws in an improvement exchange are typically routed through the qualified intermediary and the exchange accommodation titleholder rather than paid directly by the taxpayer to contractors. This usually means a formal draw schedule, similar to what a construction lender would require, with the exchange accommodation titleholder reviewing and approving each disbursement based on completed work. Coordinating this draw process with the general contractor before construction begins, so invoicing and lien waiver documentation align with the exchange accommodation titleholder's approval process, helps avoid payment delays that could otherwise slow down a project already working against the one hundred eighty-day deadline. Investors evaluating an improvement exchange for a Boston, MA replacement property typically bring the qualified intermediary, the general contractor, and the lender, if outside financing is involved, into the planning conversation together well before the relinquished property closes.

Not everything a contractor purchases for the project necessarily counts toward the exchange value. Building materials that have been purchased but not yet installed, sitting on-site as inventory rather than incorporated into the structure, generally do not count as real property improvements for exchange purposes until they are actually affixed to the building in a way that would make them fixtures under state law. This distinction matters most in the final weeks before the one hundred eighty-day deadline, when a construction project under time pressure might otherwise try to count staged materials as completed value. Appraisal support at the point of transfer, documenting the as-built condition and value of the property on the day title moves from the exchange accommodation titleholder to the taxpayer, is generally the most reliable way to substantiate exactly how much improvement value the exchange achieved, which matters if the transaction is later reviewed.

Insurance, permitting, and municipal inspection responsibilities also shift during an improvement exchange, since the exchange accommodation titleholder is technically the property owner of record while construction is underway. Building permits, occupancy permits, and course-of-construction insurance in Greater Boston municipalities typically need to be pulled and maintained in the exchange accommodation titleholder's name during that period, which means the general contractor and the project's insurance broker both need to understand the structure before applications are filed. A permit application or insurance policy issued in the wrong name can create delays that are unrelated to the actual construction work but still eat into the limited time available before the one hundred eighty-day deadline, which is one more reason to loop in every party to the project, not just the qualified intermediary and exchange accommodation titleholder, before ground is broken.

For investors who have decided an improvement exchange fits their situation and want hands-on coordination through the construction period, the site's Improvement Exchange Roadmap service manages contractor coordination, draw schedule oversight, and milestone tracking against the one hundred eighty-day deadline. Reviewing the underlying legal structure first, including why the exchange accommodation titleholder has to hold title and why the deadline caps how much value can be added, generally makes it easier for a Boston, MA investor to evaluate whether a proposed construction timeline from a contractor is actually realistic, rather than accepting an optimistic schedule that assumes no permitting or weather delays.
