Cy-Fair is a good school district, but i agree that finding a home with the specs you outlined for $65k will be nearly impossible. Some homes, mainly foreclosures, are available in the Houston area at that price range, but they're small and usually in very poor condition. Contact me, and we can talk about your options.
