In practice
In a 1031 exchange, small details decide whether the full gain is deferred: the identification deadline, the value and debt you replace, and who holds the sale proceeds. The term 180-Day Exchange Period comes up when we review an exchange or a Delaware Statutory Trust offering with a client. We read the offering memorandum, check the sponsor's track record and fees, and confirm the replacement fits the exchange rules before anything closes.
