neb: Weeelll... that makes sense, they're reporting the results of a survey of 2K people, so all of those items are just what was reported on the survey, including "other" for uncategorisable replies.
If you're generous and count "being too far from my family", once you remove "Nothing would turn me off from a property" and "other", since one is miscategorised as a turn off and one is unspecific, you're only left with 17 factors. The headline promised 18 specific factors.
I'm surprised pseudoephedrine contamination isn't on that list.
I'd happily buy a asbestos-filled deceased estate on the flight path. Must have fibre though.
