Amusing House Listings...
This house is listed here as 3 bedrooms and 2,173 sq. ft. Okay. It doesn't look that big in this picture. But, the first site that I saw it on (which won't let me link to it without giving them an email address) lists it as 3 bedrooms and 217,300 sq. ft.
It seems they are off by a factor of 100 on all homes (or at least all NorthstarMLS homes) because this house is 281,800 sq. ft. That's pretty good since it's on a 5663 sq. ft. lot. It must be 50 stories high. I suppose 47 of them are underground.
