Realty Trac does not list or sell reasl estate, they only sell information posting listings that are actually ads for their service. You are better off first checking to see if the town/city where the hous eis located ahas an online database for the tax cards through the assessors office. If not you will have to go to the town or city hall and pull up the tax crad, this will have alot of information you need. On teh card is usually teh book and page of teh last owner. you can search that to see what they paid or what they owe etc.
good luck with your search... more
