An improvement exchange, sometimes called a construction exchange, lets an investor use exchange proceeds to both acquire replacement property and fund improvements to it, with an exchange accommodation titleholder holding title while the work is completed. The catch is timing: everything, the acquisition and the improvements, has to be finished within the same 180-day period that governs a standard exchange. That is a tight window for construction work, and it is the single biggest planning risk in this structure.
Why The 180-Day Deadline Is Unforgiving Here
Unlike a standard forward exchange, where the replacement property just needs to close by day 180, an improvement exchange needs the improvements themselves substantially complete and reflected in the property's value by that same deadline. A permit delay, a contractor scheduling issue, or a redevelopment project in an area like Wedgewood-Houston running behind schedule does not extend the exchange timeline. We build the construction schedule backward from day 180, not forward from a hopeful start date, so the gap between what is possible and what is planned shows up early rather than in month five.
What Has To Be In Place Before Ground Is Broken
The exchange accommodation titleholder structure needs to be set up correctly before improvements begin, since the investor cannot hold title to the property being improved during the construction period under this structure. That means coordinating the EAT agreement, financing for both acquisition and construction, and a realistic scope of work before any contractor starts, rather than treating the accommodation arrangement as paperwork to finalize later.
- Exchange accommodation titleholder agreement finalized before acquisition
- Construction budget and schedule confirmed against the day-180 deadline
- Financing secured for both the purchase and the improvement costs
- Permit timeline reviewed against the jurisdiction's typical processing time
Matching Replacement Value To The Exchange Requirement
Getting this right takes coordination between the contractor, the exchange accommodation titleholder, and the qualified intermediary from the earliest planning stage, rather than only at closing. The improvements add to the replacement property's value, which is often the entire point of this structure: an investor may need a certain purchase-plus-improvement value to fully offset the relinquished property's sale price, and a property that is underpriced on its own can reach that number once planned upgrades are factored in. But only the value actually completed by day 180 counts. Work that is still in progress when the deadline arrives does not add to the exchange value, which is why realistic sequencing matters more here than in almost any other exchange structure.
When This Structure Makes Sense In Nashville
This approach shows up most often with value-add multifamily properties, tenant improvement work on medical office space tied to the area's healthcare employment base, or industrial buildings needing dock and clear-height upgrades before a target tenant will sign a lease. In each case, the underlying property alone might not match the exchange value needed, but the property plus a defined scope of improvements can, provided the schedule is realistic from the start.
Physician groups and outpatient clinics affiliated with the region's larger hospital systems frequently require build-to-suit interior work before signing, since exam room counts, equipment placement, and code requirements for medical use differ sharply from a standard office layout. An improvement exchange structured around that kind of tenant improvement scope only works if the build-out schedule is confirmed with the contractor and the prospective tenant before the accommodation titleholder arrangement is finalized, not after construction is already underway.
Working Backward From A Realistic Contractor Schedule
Before an improvement exchange gets identified as the plan, we ask contractors for a schedule that accounts for permit review timelines in the specific jurisdiction, in addition to the construction work itself. Permit processing in growing suburbs like Spring Hill or Mount Juliet can move on a different schedule than in Davidson County, and that difference matters when the entire project has to fit inside 180 days from the day the relinquished property closed.
If the contractor's honest estimate does not leave enough buffer against day 180, that is information the investor needs before committing to this structure, not after signing an exchange accommodation titleholder agreement. In some cases, a smaller, more limited scope of improvements that can genuinely finish in time serves the exchange better than an ambitious renovation that risks falling short of the deadline.
Common 1031 Exchange Questions
Can improvements still count if they are not fully finished by day 180?
Only the value actually completed by the deadline counts toward the exchange. Partially finished work does not add its planned final value, only its value as of day 180.
Who holds title to the property during the construction period?
An exchange accommodation titleholder holds title on the investor's behalf while improvements are completed, since the investor generally cannot hold title to the replacement property directly during this phase.
Does an improvement exchange extend the standard 180-day deadline?
No. The same 45-day identification and 180-day exchange periods apply, which is why construction timing has to be planned with no assumption of extra time.
What types of improvements are commonly financed this way?
Tenant improvements, structural upgrades, and value-add renovations are common, particularly on multifamily, medical office, and industrial property where the improved value helps meet the exchange requirement.
Is this structure more expensive than a standard forward exchange?
Generally yes, due to the exchange accommodation titleholder arrangement and additional coordination required, so it is typically used only when the improvement value is genuinely needed to complete the exchange.
