How come people believe they need to own a house in order to marry and raise a family? Historically speaking, most people always rented, and only the rich owned homes, at least in Europe. This is where the term "landlord" came from, the literal Lord of the land people resided on.

Renting in modernity has almost nothing in common with renting in pre-modernity, other than the name.

A landlord today doesn't live in the land he's renting, in fact he may only know what it looks like because someone sent him a picture of it. His stake in the land is PURELY financial. That's why your rent goes up every year, forcing you to move out eventually. He doesn't care a hoot about providing a stable home, which is necessary for the flourishing of literally every animal in existence, especially human ones (this is especially true of corporate landlords, which are most landlords-- there may be some exceptions here and there). Renters lack stability-- not just financial stability. Not that it's their fault (necessarily).

Land lords in the pre modern period didn't just own the land their tenants worked, they lived on it. It was their heritage and they were tied to it blood and soil style. As such, he understood and typically fulfilled certain duties to his tenants, not because some regulatory board required it, not because it was good for the brand of his corporation, but because that was his land and his heritage and as a result those working it were an extension of the same identity. It was common for families to work and live on such land generation upon generation. This is often how you get villages and towns. At the end of the day the technical ownership of this or that property or structure on the lord's land was effectively irrelevant because people were able to live well. I don't mean live luxuriously, I mean live with their social, economic, and religious needs satisfied-- they were able to flourish in the natural sense of the word. And that's what counts.

At any rate, the modern renting arrangement looks absolutely nothing like historical renting.
