If during the current tax year you transferred property to another party in a like-kind exchange, you must file Form 8824 with your tax return for that year. Also file Form 8824 for the 2 years following the year of a related party exchange. See Line 7, later, for details. Section 1031 regulations.
You can perform a 1031 exchange with foreign properties, so long as your relinquished and replacement properties are both located outside the United States.
A Qualified Intermediary, or QI, is an independent third party to the transaction whose function is to prepare the documents necessary to create the exchange, as well as to act as the independent escrow agent for the exchange funds.
