The property to which you linked is not for sale, as has been noted in prior comments. When it does go in the market â€“ whenever that may be â€“ it will not be offered for $1,000. I am sure you are aware that the ground beneath the home is worth far more than that.
What you have seen on Trulia is a notice of default or foreclosure posted by Realty Trac which is a reporting service.

It is unlikely that you will be able to buy this house for the price posted on Trulia. That is the amount of a default and has no relationship to the value of the property. The house may be offered for sale at a later date but it will most likely be listed with a Realtor and priced at a price that reflects the market price for the area.
If you are serious about buying a house, you need to align yourself with a full-time, experienced local Realtor who can help you to find the house that meets your needs. Your Realtor can help you to learn about the current market conditions, realistic house prices, loan qualifications, negotiating strategy, escrow management, inspections and everything else that goes into the purchase of a home.
