The Clear Lake area of Houston is also a good place. The Clear Creek school district is one of the best around the Houston area abd the property is, in general, cheap. Another thing to consider is what county you might be moving to since (ditto) Harris county has some of the highest insurance rates around. League City is really growing and there are some really nice homes there. I live in Harris county, so we just put up with the insurance hikes and save a little in taxes compared to Galveston county, which were the two areas we looked at.
