Hi OP Resident,
Realty Trac will show activity on homes, but it does not mean the home is on the market. For example, if a borrower defaulted on there home and the bank who owns the property filed a notice of foreclosure or lis penden, etc, the borrower can still work with the bank to redeem the home. Also it can take months or even years for the property to even show up on the market. If you are looking for a great deal, speak to an agent and have them send you up to date listings of what is available. If you are looking for a foreclosure, I HIGHLY recommend that you work with an agent. It is very difficult to get a hold of some agents that list large amounts of foreclosures. A selling agent will be able to get you into these homes immediately. The best part of it all is that it will not cost you a dime! Hope this helps!
