I actually have 2 listings for under $5k that you may be interested in. They both require some work. Would you be interested in getting more information? If so contact me at firstname.lastname@example.org. Below is an electronic version of my business card. Give me a call and let me help you find something.
A house for 5 grand or less is going to be pretty tough to find. You're more than likely going to have to put quite a bit of money into fixing it up and making it livable. You need to provide more information.
You should also contact a good Realtor, who has access to the MLS, (the broadest system available) for access to any and all properties listed for sale in that type of price range.
