HOW many zeros is that?
Here when we see 3/2 or 3/2 1/2 it's number of bedrooms with baths. A half bath has a toilet and a sink, with no shower or tub.
7 room house with 3/2 would be three bedrooms with four other rooms (not counting bathrooms). One of the four would be a kitchen, leaving three of which one would be a living room leaving two which could then be a parlor, and a dining room, ect.
That's a long way to go Claire! Is it certain, or just in the "maybe" stages right now?
