We have a home in
Clifton (near Waco) TX where the winters are mild but the summers are HOT -- it's even hot at night. We live most of our time in Panama up in the mountains where the outside temperatures never go above 75 deg. F, and some times when the temp goes to its minimum low of a frosty 65 deg. F we put a log in the fire place.
It depends on what's important to you. Both TX and NH are beautiful, but TX is a lot less expensive.
