Sometimes HUD homes and even bank owned homes only reflect the square footage that is above ground level. When I post a listing, I always take the square footage from the assessors site, not previous listings, that way it's a little more accurate.
Are you looking for a home? I'd be glad to help you find what you're looking for. Just give me a call or email whenever you have a chance.

Our tax records also distinguish between above ground and total sq. ft.
I would be interested to know where you might be seeing only the First floor sq. footage, and would be happy to get you more accurate information about any homes you are interested in.
