ts not hoe much space you have, it is how well it is laid out.
we have about 3000 square feet if you count the basement (which is unfinished but dry, ventalated, heated and carpeted and the walls are not nasty gross - all this makes sense to people who have a basement
we have 2 adults and 2 children.
the house has the basement which holds out huge furnace, washer dryer, dh office, his shop and the kids tunnels and tents (but we only got these because we had the room to spare. :LOL) main floor - living room dining room and kitchen (3 cupboards and 2 drawers in the kitchen, one closet in the dining room - otherwise no storage space) up stairs is three bedrooms and a bathroom and the 3rd floor is a low celing playroom with 2 big closets and crawl space storage. We have a small yard and a 2 stall but illegal (as in we could be told to knock it down at our neighbors whim. of if God should so choose to flatten it and we would not be allowed to rebuild )
and we are looking to trade it all in for a very small 1200 square foot, 2 bathroom, 4 bedroom dream home. I am telling you. a reasonable well used space is so much better than a very large poorly used space home. You are looking at someone who is a huge fan of the galley kitchen though. Also small bedrooms. Just big enough for a bed and dreser. On the up side we should get a good deal on the house that no one else wants.
