A Replacement Property is considered identified before the end of the 1031 Exchange 45-day identification period only if the following requirements are satisfied. However, any Replacement Property you receive before the end of the identification period will in all events be treated as identified before the end of the identification period.
A Replacement Property is identified only if it is designated as Replacement Property in a written document signed by you. This document must be sent before the end of the identification period to a person (other than yourself or a related party) involved in the exchange.
