You are not in the Northeast. heh.
That is probably the biggest difference.
In certain areas where housing prices are through the roof I could see it being a negative I'm you had a 2 bedroom home that could be 3 if you didn't have the damn audio/media room.
The homes we build, sell, etc typically have a minimum of 4 and many as high as 6 bedrooms. We don't have to give up functionality of the home to have the media room.
