Interior area
The listing does not state an interior floor area. Lot size, where it is given, measures the land instead.

Detached
Style as listed: 2-Storey.
Second dwelling
The listing does not say whether there is a second dwelling unit here. Other records in this set state it either way, so this is a silence rather than a no.

None of these is an appraisal. Your lender orders one of those once an offer is accepted, and it is the figure that decides how much they will actually lend.
