If it is a LISTING at $1,000 (you will find it is not) then yep, you have the opportunity to buy it for $1,000....providing you meet all the associated criteria. That all the fine print you did not see or have elected not to share with us.
It is highly likely you observed this on Trulia. It is a advertisement of deception. You already know "If it's too good to be true...." and this is no exception.
If you are serious about making a real estate purchase you should rely on serious tools. Real estate data appearing on Trulia and Zillow are for entertainment purposes for the sole purpose of selling advertising to real estate agents. If you are serious, promote yourself to serious tools such as REMAX.com or Realtor.com or ANY real estate professional website. Better still, pick up the phone and CALL a REALTOR to get plugged into the real database.
Best of success
