My hometown of Smethport, PA, has many large houses on Main Street...homes where the elite of the time (late 1800s) lived. One of the houses is up for sale and it has some space, all for only $345,000!
Billiard Room: 17' x 26'
Sleeping porch: 9' x 31'
Bedroom 3: 18.6' x 15'
Bedroom 8: 19' x 13'
No wonder that a few of them have served as B&B's over the years.
