Oh boy ... I hope you got enough of a down payment to cover the recaptured depreciation if not you are going to be unhappy with your bottom line on the form 1040.
For the installment sale form 6252 you will enter all payment received at closing and during the year ... so if all you got was the interest then that is all that will be reported on the form 6252. In the rental section go slowly to indicate the sale and the disposal of all the associated assets. I highly recommend you either seek local professional assistance OR upgrade to the LIVE option for one on one guidance if you do not feel you understand what is going on.
