Can the proceeds from the relinquished property be used to make improvements to the replacement property?
Yes. This is known as a Build-to-Suit or Construction or Improvement Exchange. It is similar in concept to a reverse exchange. The taxpayer is not permitted to build on property she already owns. Therefore, an unrelated party or parking entity must take title to the replacement property, make the improvements, and convey title to the taxpayer before the end of the exchange period.
