My experience is that it is a significant percentage (i.e. more than 10%)... And about your point about home owners being poor - not everybody owns their own home (stats show it's about 2/3rds). I just don't see BTL as realistic for people struggling to make ends meet.
I said the metric of "money held in the bank" would count many home owners as poor, even if they own a house that is worth 1 million dollars. Not that they are actually poor - that is the point. The metric may not be very useful.
