There is one active property in Hackberry Creek that is just slightly over your budget but with some negotiating I'm sure we can get it within your price point. While there aren't many houses within Hackberry Creek priced 250,000 or less, a few pop onto the market every now and then. I would be happy to show you the home that is listed now or set you up on an automatic search that will email you new properties that fit your search criteria as soon as they come onto the market. Give me a call if you would like more information.
