So 2 things to make sure of when talking to lenders about your scenario.1) Do they have a seasoning period before you can refinance and if so what is it.

All of the tax liability, the capital gain and the depreciation unrecapture, are deferred...For the 1031, you really don't have long to identify (one time period) and then close on the "exchange property(ies)" (a second time period).

Pick any 4 year period over the last 75 years with the exception ofthe 2007 subprime crisis and the housing on average increased.
