On the Low to mid range homes I think we have entered a classic wall of worry situation.
I have never been a high end home type of guy to tell the truth so would not know what goes on at that level or why anyone would spend 1 Mil+ on a home.
But I guess it is nice to be at the beach etc… but if I can get there in 15 minutes to half hour and put my toes in the sand I figure I can afford the AC the few times I actually need it as well.
