Homes are priced essentially by (1) location and (2) condition. The higher the price, the greater the demand for property in the area ... conversely, the less desirable the location (for whatever reason) the lower the price. In either case, it will cost more if the home is move-in ready and updated ... and if it needs work, the price will be adjusted accordingly.
You can get information about the schools in the area here ... http://www.aliefisd.net/ ... TEA ratings should be there for every school ... you'd want to see Recognized or Exemplary. Academically Acceptable simply means that the school meets minimum standards ... not very encouraging.
Everything concerning real estate can be negotiated ... except where the home is. Major thoroughfares such as Richmond are certain to be busier and noisier than locations within subdivisions. I suggest you visit the area at several times of day, including rush hours. That should give you a better idea of what you can expect.
If I can help any further, please feel free to contact me. I look forward to hearing from you.
If you need to be semi close to town, this area is very affordable and close, but the Katy area is a bit safer and as affordabable...just a bit more of a commute in town
