You'll need to work directly with a Realtor. Through the MLS system we generally have access to most sales prices. Texas is a non-disclosure state and therefore sales are not reported/recorded generally at the courthouse. I recommend you always use a Realtor when purchasing a home. It will should lower your price, save you lots of time, and reduce your risk. I'd be happy to work with you if you have not already signed a buyer's representation agreement with another agent.
