Jay, As far as short sales go , which is mainly where the problem is....the banks want the homes listed until the short sale is approved. Since this is such a long process the homes are listed as active for a long time. Technically, agents are required to accept offers on homes while it is "active". However, there are so many offers coming in that they simply don't want any more.
Our Board Of Realtors here made it mandatory that if an offer is waiting approval from a bank then it must be moved from "Active", status.
Confusing market, I know, but keep trying...good luck to you!!!
