The comments here are making some odd assumptions:

1) That buying implies owning your own top-to-bottom house, with no adjacent neighbors.

2) That renting necessarily comes with arbitrary rent increases and risks of eviction.

3) That mixed communities of buyers and renters are uncommon.

None of these is necessarily true if you live in a city, depending on the city. It sounds like a lot of people are actually comparing “living in an apartment/condo” to “moving out to the suburbs,” not renting vs. owning.

Isn't that also what the OP is doing? They are comparing renters to owners who are usually in a different life situations (with the basic being kids vs no kids).

There are a lot of compounding factors OP is ignoring, likely out of not being in a set of life situations yet.

Thus commenters are bringing counter-exampled to dispute the OP claim, not as the 100% truth either.
