Generally that's what mortgages are for. Considering rent needs to cover the cost of [ mortgage + expenses + the landlord's profit ] anyone that can afford rent can afford the mortgage.

That's not to mention the reason housing prices are so absurd is because landlords are buying up all the available supply in order to profit it off of it existing. Without landlords housing becomes much more affordable.

What about people who want the freedom to move from place to place without being tied down, too bad, they have to own a place?

We are having a housing crisis right now. So how about we worry about the large group of people who want to own shelter and can't, and then we can worry about the much smaller group of people who have the means to move constantly but find hiring a realtor just too much effort.
