That's another reason I do not recommend people to buy houses that claimed to be foreclosure; most of them are just phising since, as you just confirmed there are tons of buyers out there in the market. Whoever said real estate market is bad is just fraud ...
Dirk is right, just lay down those signs from irresponsible listing agents as we did here in our hometown. Those signs was there to lure buyers, but that also convey misleading information.
The real estate is still very healthy and people want to sell the house can sell. Those shown the for sales sign like yours in the media or newspaper, in fact, all sold; they just trying to scare the governement to steal taxpayers money.
On the other hand, that listing agnet must enjoy all the buyers attract from someone else ads to your home and find the sign and call the listing agent to buy. So, why not get the free referrals?
