Client, who is a small time contractor, came across a good price on a house and lot that needed repair.  He and his wife purchased it,  remodeled it and sold it for a gain.  He spent most of the year fixing it.  Where on the schedule D do I report the gain.  And /or since he did keep track of his time and what he would have charged, do I put some of it on a schedule C.   HELP!!
