I read all your responses, and I enjoyed reading them. So I responded below in italic to some of your comments/questions in no particular order.
lucky - Where is the light fixture you want to order the prewire?
exterior light in the so call backyard/side yard (I'm leaning not to get it)
lucky - Additional data ports are awesome. Pro tip: if you're like me and won't be having a hardwired telephone line, you can also use your telephone jacks as data lines because they're wired with Cat-5 as well.
Yeah, but I want a data port that is opposite of the existing telephone port in the bedroom. So one of the rooms I would turn into my office. I plan to bring my existing L shape (shaved glass look) desk, and place my dual desktop monitors on one side. On the other side of the desk, it will be empty (use for reading/paperwork/place bills/magazines) because I would place the tv on the wall [which will be above that side of the desk]. (tv will be mounted on the wall w/ the in-wall conduit) For the other side of the office, I plan to have a futon (that can convert to a bed for the guest or a small movie room if I'm too lazy to walk downstairs to the "great room" haha).
Irvinecommuter - You can just get wireless routers.
I already have one for my current place and I will also bring it to my new place. (to surf with the ipad around the house wirelessly) When I move to the new home, I am planning on streaming netflix/hulu from my tv and the streaming performance is better when it is connected "wired". l will order just two data ports, for the two other bedrooms so I can have a data port below the tvs.
broda - Did 4 lights per bedroom because well it just looked even to me...we thought about doing 2 but I felt like it would look weird.
I had the same thoughts also.
broda - Ceiling fans I did master bedroom and great room.
Same here - added one more for my little one's bedroom for the future. I was thinking getting the ceiling fan prewire for the office, but decided not to.
No Quarter - Not sure if you are past this part or not, but upgrading the door handles to the lever style was something Mrs. No Quarter and I disagreed on. She felt it was unecessary and that a knob would suffice.
I know what you mean about the style of the knobs. I had to change the knobs back when I moved into the current place now, I changed all the knobs for a modern looking one.
bones - For the bedrooms, we actually did not do canned lighting - thought it was too harsh and unnecessary. We just use bedside table lamps and the light from our ceiling fan and that seems to provide enough light for the bedroom.
Thats what I have now, bedside lamps/traditional lamps and its kind of dark. Also, my little one likes to lean/push down the lamps, and broke one. That is why I am getting recess lights.
NewGirl - my advice to you would be to be as SPECIFIC as possible with all upgrades
Thanks for the tip. This weekend I am going to bring my measuring tape, pen, and a note pad, to the model home to take measurements.
For downstairs, I was thinking about getting the standard tile in the kitchen, and carpet for the great room area. Then rip out the carpet and replace it with hardwood. I was considering getting wood in the kitchen, but I would have to stay on top of spills as liquids can cause damage if not wipe/cleaned right away. My wife cooks, and my little one likes to "help" cook /play/eat - which leads to multiple daily spills in the kitchen - I think tile is the best option for me.
Thanks for sharing your inputs/stories!! I have around one and a half week to decide for my electrical.
