There are definitely more than 4000 homeless people in the country, no idea where that figure came from!
Ultimately we do need more houses, we have plenty of room! But it's not just that there is a tonne of low quality housing with damp and mould problems, they also need sorting out!
Another factor is lonely old people in massive ex family homes that can't afford to heat them, it's bonkers.
The distribution is just all wrong!
