Housing shortage? Probably, but why? In a town I lived in for a bit 50% of the houses were second houses, i would drive around and see them all dark, sitting there empty. Her where I am now, the housing has been moved over to AirBNB. It is all greed.
And go to a poor town? And not have healthcare, be away from my friends and support? But yes, I have tried it. They ask me what I do and when I say I am on disability they deny me the rental. And many of these towns will not let you live in your van while you are looking.
It is inequality, not a shortage.
I am telling you, you have no idea what it is like.
