Unfortunately the amortization schedule we received in one case starts with 2014 figures, and the sale was in 2005.  A further complication is that payments have not been completely regular.  It would be nice if ProSeries would allow a dummy figure to be entered if the original info is not available.  I have heard a workaround is to just enter $100K as the sale and an appropriate basis figure to yield the established cap gain percentage. Hmm.
