Guides
How an improvement exchange lets Orange County investors use exchange proceeds to construct or renovate replacement property before the 180 day deadline.
An improvement exchange, also called a build-to-suit exchange, allows exchange proceeds to fund construction or improvements on the replacement property, not just its purchase price. Because the investor cannot receive constructive benefit from improvements made after taking title, an exchange accommodation titleholder holds title to the replacement property while construction takes place, similar to the structure used in a reverse exchange.
Construction must be substantially complete, or must have added value at least equal to the improvements funded with exchange proceeds, before title transfers to the investor, and the full arrangement must conclude within the 180 day exchange period. The 45 day identification period still applies, and it requires the investor to describe the property as specifically as possible as it is expected to exist at the end of the exchange period, including the planned improvements.
A 180 day window is a compressed timeline for ground up development, so improvement exchanges are more commonly used for renovations, tenant improvements, or smaller build-to-suit projects. Orange County investors pursuing this structure in markets like Santa Ana and Costa Mesa have the best results when entitlements and permitting are already in place before the exchange begins, leaving the construction period focused on actual building work rather than approvals.

Frequently Asked Questions
What is an improvement exchange?
An improvement exchange lets exchange proceeds fund construction or improvements on the replacement property before the investor takes title.
Who holds title to the property during construction?
An exchange accommodation titleholder holds title to the replacement property while improvements are completed.
How much time is available to complete construction?
Construction must conclude within the 180 day exchange period, the same deadline that applies to a standard exchange.
Can ground up development be completed within an improvement exchange?
Ground up development is difficult to complete within 180 days, so improvement exchanges more often fund renovations or tenant improvements on properties with existing entitlements.
How is the replacement property identified within 45 days if construction is not finished?
The investor must describe the property as specifically as possible, including planned improvements, as it is expected to exist at the end of the exchange period.
What happens if construction is not complete by day 180?
Only the value of improvements actually in place by day 180 counts toward the exchange, and remaining exchange proceeds may become taxable boot.
