Buy in an area serviced by a H2O company ie Canyon Lake Water Supply Corp The ground water supply around here is getting iffy if you're planning on property and a well. If so drill the well first before you start on your house. Lot's and lots of holes being poked into the Trinity. If you do buy land and drill don't expect a plethora of water and don't drill shallow. In times of drought older wells have gone dry entirely or will provide water for 15 minutes and then need a couple hours to recharge for another 15 minutes worth. Access to adequate water is soon to become a major hurdle because of all of the development up this way.
