This page will provide you with helpful links for living in Texas! The first link to the right will show you links to almost every Non-Profit group around.
The second link takes you to a Metroplex Guide page where you will find information on different communities, entertainment, government, etc.
The third link, Zillow.com, allows you to search specific addresses to see the lot lines, arial views of the street and homes, and a lot more. It's a fun link to use, however the estmated property values are rarely accurate.
The fourth link is the Dallas Central Appraisal District's official site where you can find tax records for any Dallas County property. You can also click on the Map feature for any property and see a map of its location or measure the lot.
