Owning a home might be meaningless from a purely aspirational (or whatever) point of view, but it isn’t at all from a purely practical perspective. The lack of social housing stock and poor renter’s rights in this country and a rental market that, in certain parts of the country, keeps getting worse and worse value for tenants means that long term renting is not attractive for anyone aiming for financial security. It doesn’t need to be this way, but that’s the current reality.
I agree that sacrificing your 20s for the sake of an unattainable mortgage is daft, but so is pretending that there aren’t tangible benefits to owning vs renting that go beyond the national fetishisation of owning your own home.
