Who rents for 20 years and then acts all surprised that they don’t own the house? If your end goal is to own a house, start by buying a house. If you can afford to rent and pay off someone else’s mortgage then you can certainly afford to pay off your own mortgage.
How is someone supposed to save for a mortgage when they’re busy paying off someone else’s mortgage?
Well, because as a class they raise the cost of land, meaning that many peoples only option is to rent. And then you have to pay off their mortgage for them.
Note that in the USSR apartments were 5 percent of income. That is what the actual cost of maintaining homes for people is, when you remove all the rent seeking and property speculation.
You certainly can, right? But that doesn’t mean you’ll qualify for a loan.
