A lot of great places in SW Virginia too. Check out Bristol (VA or TN) Smaller town, close to a regional airport with service to the major hubs. Good friendly folks. The advantage to Tenn is no state income tax, (although the sales tax is very high).
Other options would be the Blacksburg or Christiansburg (VA) area, I lived there many years and my wife grew up in that area. Great people, 30 mins to Roanoke (with a regional airport). In the years I lived there, it never went below 0 and never above 90. We actually had homes with out central air and really didn't need it.
Property taxes are low, housing is dirt cheap! You could sell your LA home and buy several homes.
