Improvement and Build-to-Suit Exchange

An improvement exchange, sometimes called a construction or build-to-suit exchange, lets exchange proceeds fund construction or renovation on the replacement property rather than just the purchase price. This matters when the ideal replacement is not a finished asset available at the right value, but a property that needs work, an addition, or ground-up construction before it matches the value of what was sold. The structure uses the same exchange accommodation titleholder mechanism as a reverse exchange, because the improvements have to be completed and the property titled a specific way before the exchange can close.

Exchange funds can only pay for improvements made to property the exchanger does not yet own. Once the exchanger takes title to the replacement property, any further improvement spending is the exchanger's own after-tax money, not exchange proceeds. To work around this, the accommodation titleholder holds title to the replacement property during the construction period, using exchange funds to pay for the build-out, and only transfers title to the exchanger once the work that will be paid for with exchange funds is complete or the 180-day period is closing in.

This is the detail that trips up exchangers who assume a construction timeline gets its own separate schedule. It does not. The full value of the improvements intended to be covered by exchange funds has to be in place, and the property has to be conveyed to the exchanger, within the same 180-day window that governs every other exchange. A ground-up build rarely finishes in 180 days, which is why improvement exchanges are typically used for renovation, tenant build-out, or partial construction rather than a full new structure, unless the project was already substantially underway before the exchange began.

Because the replacement property is identified before construction is complete, the identification has to describe the property as it is expected to exist at the end of the improvement period, including a reasonably accurate description of the planned improvements. If the completed improvements fall meaningfully short of what was identified, the exchanger risks having identified a property that does not match what was actually acquired within the window. A conservative, well-documented scope of work at the identification stage protects against that mismatch.

Improvement exchanges come up in Pitkin County when the highest-value replacement option is an older commercial building or a condo-hotel unit that needs a renovation to reach market rents, or a partially developed parcel that needs site work before it functions as an income-producing asset. Given how compressed general contractor availability and permitting timelines can run in a mountain resort market during peak building season, the construction portion of the plan needs to be scoped and scheduled with the 180-day deadline as a hard constraint from day one, not treated as a flexible target that construction crews will simply meet.
