mortgage old vs new can also affect basis because a decrease in mortgage balance is treated like sales proceeds.
what about exchange expenses they affect the basis of the replacement property. you did use a qualified intermediary, didn't you? 1031 exchanges are reported on form 8824
also remember that your depreciable basis is net of the depreciation you took on the original property. I do not know if TurboTax tracks this so you must. even though you did a like-kind exchange that previous depreciation does not go away and is subject to recapture upon the sale of the replacement property where there is no like-kind exchange involved. It is more like the cost of the property is 150 with 50 of accumulated depreciation to start
