The house was built in the 1950s, there was some remodeling, but no pre wiring, we bought it when it was almost complete, minus just a couple things. all wiring will be able to be either on the far side of the house, where no one can see it from anywhere unless they walk to that side, which has woods and one neighbor. or it can go from the basement to the rooms. there is only one other run of cable that needs to be made, and that can easily be hidden in the soffit. and yes I will be adding some Cat6 cabling to the house at some point. but again everything can be done from the basement pretty easily.
The only things we have had to do this house was change some paint colors, put down carpeting, and fix some minor wiring issues.
The wife is on board with anything I need to do with wiring as long as there are no wires running across floors and everything is hidden. I am actually going to be able to get rid of some of the nasty wiring that is already in the house, from where the previous owners had Sat, and have double cables ran through walls and up floors.
If I was to build a new home from the start, it would probably have double runs of cat 6 and high end coax to every room.
