Six month fixed price on an REO?

[Amie D.]

There is a foreclosure that has been on the market for four and a half months. It has been under contract twice and then fallen through, with the listing price lowered once about six weeks ago. The selling agent has explained that the property may only sell for the non-negotiable list price for six months. After that it can go to a more marketable price and can be negotiated like a normal sale. Has anyone else run into this?
