This credit amounts to $1,666 per month, with the monthly rent set at $3,300.From an accounting perspective, should the $1,666 per month be treated as a liability (deferred credit) and excluded from income, or should it be recognized as income and then applied as a credit at closing?

I haven't done a 1031 exchange, but may in the near future and the small amount of research I have done on it seems to indicate that some qualified intermediaries only do the intermediary task (hold your money while you close on the new deal) and some try to do other tasks as well, like facilitate you finding the next deal, etc.
