Improvement and Build-to-Suit Exchange

An improvement exchange, sometimes called a build-to-suit or construction exchange, allows an exchanger to use 1031 proceeds not just to buy a replacement property but to improve it, adding construction, renovation, or new development value before the exchange closes. This structure fits an Indianapolis owner who sells a fully leased retail building and wants to roll the proceeds into a smaller property near Carmel that needs substantial renovation to reach an equivalent value, rather than settling for a finished property that costs more than the exchanger wants to spend.

Like a reverse exchange, an improvement exchange requires an exchange accommodation titleholder to hold title to the replacement property while construction happens, because the exchanger cannot directly own and improve the property with exchange funds during the exchange period. The titleholder acquires the property, applies the construction budget as improvements are completed, and transfers title to the exchanger once the work is finished or the 180-day deadline arrives, whichever comes first.

This is the detail that catches owners off guard: whatever improvements are completed by day 180 count toward the exchange value, but construction that is still underway when the deadline arrives does not. An exchanger planning a full renovation of a Fountain Square building needs the contractor's schedule to realistically fit inside the remaining window after accounting for permitting delays, which is often the tightest part of the whole process in a market where permit turnaround can vary significantly by township.

Exchange funds held by the titleholder are typically released in draws tied to completed construction milestones, similar to a construction loan, rather than handed over as a lump sum. This means the improvement exchange requires more upfront planning than a standard purchase: a realistic budget, a contractor with a track record of hitting deadlines, and a draw schedule the titleholder and the qualified intermediary can administer without slowing down the work itself.

This structure is most useful when the available replacement inventory in a submarket doesn't match the exchanger's target value on its own, such as a smaller industrial building near Plainfield that only reaches full equivalent value once expansion or updated loading infrastructure is added. It's less useful for cosmetic renovations that don't meaningfully change the property's value, since the additional cost and complexity of the titleholder structure isn't worth it for improvements that could just as easily happen after a standard exchange closes.

Permit turnaround varies meaningfully across Marion County and the surrounding townships, and an exchanger planning an improvement exchange needs to build that variability into the construction schedule from the start rather than treating permitting as a formality that happens automatically. A straightforward tenant improvement in an existing shell can sometimes clear review in a few weeks, while a project involving a zoning variance or a site plan amendment near a growth corridor like Whitestown or Plainfield can take considerably longer. Since only completed value counts by day 180, a schedule that assumes optimistic permitting turnaround is one of the more common ways an improvement exchange falls short of its target value.

At the close of the exchange period, the replacement property's value for exchange purposes is based on the purchase price plus the value of improvements actually completed, not the projected value once the full renovation is finished. If an exchanger buys a building for $700,000 and plans $300,000 in improvements to match a $1 million relinquished property, but only $180,000 of work is done by day 180, the exchange is valued at $880,000, which is short of full equivalent value and can leave a taxable gap. This is why appraisers and the qualified intermediary typically confirm completed value near the end of the window rather than relying on the original construction budget alone.
