Our house is somewhere between 1,800-2,000 sq. feet. We also are lucky to have a really large yard. It's 4 bedrooms and myself, my husband and daughter with our 3 dogs and 3 cats have plenty of space.

My brother and nephew moved in with us last summer...we still have plenty of room and I think the fact that sometimes it feels too small has to do with the fact that we have extra house guests more than the actually space. : /

Like others said, your stuff ends up filling up whatever space you do have. Good luck and have fun house hunting!!
