I think it's worth understanding what the basic appeal of promoting home ownership is, from a small c conservative position.
Basically, people renting, even renting from the state where there isn't a profit element, are not increasing their equity in the way home owners are. nd there are plenty of people who have complained that the less well off can't get ahead because they watch their money going down the hole of rent every month, because they cannot, for example, borrow money against the equity they have in a property. And like it or not, home ownership represents a substantial investment that people can tap into when they are older.
No matter what, rents don't end up being that much cheaper than a mortgage unless they are subsidized, because the basic costs of land and materials and labour are the same.
The other element that is a bit more abstract is that when you own, it gives a certain kind of independence that can be empowering. If you rent, even from government, you are in a certain way at their mercy. Whether they are bad at upkeep, or have stupid rules, whatever.
So the idea of trying to create a situation where lower income people are able to put their money into ownership rather than rent, makes a certain kind of sense.
The devil is in the details though, and in a mixed market where real estate is overheated there is a lot of potential for exploitation and I am sure trying to close those gaps must be very difficult. I suppose really the biggest problem is the overheated real estate market.
