Demographics is something for the buyer to work out, Penny. There are enough resources at hand to make determinations about specific issues you feel need to be addressed and answered to your satisfaction and liking starting at the federal level, then state and county, and down to the local and municipal governmental level; schools, shopping, transportation, places of worship, etc. It's all there.
If you are not familiar with driving in the area, ask your buyer's agent for a tour of neighborhoods of your choice and see a few homes at that time, too. This will help you start to get the lay of the land.
Taxes for homes in the 300,000 range could run 7500-10,000, depending on the home.
What price range are you looking for?
I have a number of useful links with school and town information on my website - feel free to take a look..........
Let me know if I can be of further help.
