An improvement exchange, sometimes called a build-to-suit or construction exchange, lets an investor use exchange funds not just to buy a replacement property but to improve it, adding value through construction or renovation before the exchange closes. It solves a specific problem: sometimes the best replacement property is not a finished asset but raw land or a building that needs work, and paying full exchange value for something that still needs improvement requires a structure a standard exchange cannot provide on its own.
What an Improvement Exchange Adds to a Standard 1031
In a standard exchange, the replacement property has to be worth at least as much as the relinquished property to fully defer gain. An improvement exchange lets construction costs count toward that value, so an investor selling a fully improved South Carolina property can acquire raw land or a distressed building for less than the sale price and use the difference to fund construction, as long as the improvements are completed and in place before the exchange closes.
How the EAT Holds Title While Improvements Are Made
Because the investor cannot hold title to the replacement property before the exchange formally closes without breaking the structure, an exchange accommodation titleholder holds title during construction, the same parking mechanism used in a reverse exchange. The EAT contracts for the improvements, pays contractors from exchange funds, and transfers the improved property to the investor once construction is complete and the exchange closes. This means the investor is directing the construction process without being the legal owner of record during the build.
Which Improvements Count Toward Exchange Value
Only improvements that are actually completed and physically part of the property by the time the exchange closes count toward the exchange value. Materials purchased but not installed, or work still in progress, generally do not count, which makes the construction schedule a central part of the exchange plan rather than a side detail. A South Carolina investor building out a retail shell or renovating an older multifamily property has to plan the construction timeline around the exchange deadline from day one, not adjust the exchange around the construction schedule.
The 180-Day Ceiling on Construction
The same 180-day deadline that governs every exchange applies here, and it does not extend for construction delays. A build-to-suit exchange effectively compresses design, permitting, and construction into whatever time remains after the relinquished property sale, which is often the tightest constraint in the entire structure. Permitting timelines in South Carolina vary by county and municipality, and an investor planning an improvement exchange should confirm realistic permitting and construction timelines for the specific jurisdiction before relying on this structure, since a permit delay in a smaller county can consume weeks the exchange does not have to spare.
Where Improvement Exchanges Fit in South Carolina
Improvement exchanges show up most often when an investor is trading out of a fully stabilized property, a shopping center in Columbia or an apartment complex near Greenville, and into land or a value-add asset that needs work to reach comparable value. Given the compressed timeline, this structure tends to work best when the construction scope is well defined before the relinquished property even goes to closing, rather than being figured out afterward under deadline pressure.
Lining up contractors, permitting expectations, and a realistic budget before the relinquished sale closes gives the improvement exchange the best chance of finishing on time. Investors who wait until after the sale to start those conversations are effectively starting the clock later than the deadline allows for.
Frequently Asked Questions
Can exchange funds pay for construction on the replacement property?
Yes, through an improvement exchange, exchange funds can pay a contractor for construction or renovation work, as long as an exchange accommodation titleholder holds title during the build.
Do materials purchased but not installed count toward exchange value?
Generally no. Only improvements physically completed and in place by the time the exchange closes count, which is why the construction schedule has to be planned tightly around the deadline.
Does the 180-day deadline extend for construction delays?
No, the same 180-day limit applies regardless of construction progress, which makes permitting and scheduling risk a central planning factor for this structure.
Who holds title to the property while it is being improved?
An exchange accommodation titleholder holds title during construction and transfers the completed property to the investor when the exchange closes.
Is an improvement exchange more complex than a standard 1031 exchange?
Yes, it requires the same parking structure used in a reverse exchange plus construction management within the exchange timeline, making it a more involved and more costly structure.
