Nearly all of us here on Trulia warn against believing the information on RealtyTrac. And nearly all of us advise people not to sign up for the trial period.
As Scott notes, what appear to be RealtyTrac "listings" are actually ads. Most of those homes aren't for sale, and for those that are, few are listed for the price in the ad. RealtyTrac neither buys nor sells homes.
Why, oh why, did you ignore that advice?
Here's what you do:
(1) Cancel your RealtyTrac subscription immediately.
(2) Contact a Realtor around Marshall to help you locate properties (including foreclosures, if that's what you want) that really are for sale.
good luck with your search
