congratulations! bought my first 6 years ago, and moved into my current just last july. sure, there's alot of costs at first because you're never happy with everything when you first move in, but sniper's right, there's something comforting about the freedom that comes with it being "yours".
do the joe room while you can....my blueprints were co-opted and redesigned into a playroom for the kids....(sigh)
