I'm suggesting 2 ref flat as it is the most common selling point - anything above goes unsold for a long time without any interested buyers, and it even is possible to get one of these for less than that (see: classifieds, market). However, due to the quicksellish nature of listings below 2 ref, I'm excluding them from the range.
