2,500 to 3,000 sqft
A band, not a measurement. Interior area as the listing states it. It does not say whether the figure was measured on site or taken from builder plans.
Property type
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.

Three parties produce a dollar figure for this house, for three different purposes, so they do not agree and were never meant to. The gaps are worked out here rather than left for you to hold in your head.

Set by the seller and their brokerage. It is a request, and nothing tests it until an offer arrives.
