Most people who claim to “own” houses don’t own them. Banks do.
In addition upkeep of the house costs a lot so in order to maintain your house properly you need to make a very good money. Of course many people don’t do upkeep as they don’t make the kind of money so their houses are a dump
Also many people are “house poor”. All their money go into that and they don’t even enjoy life. So enjoy your nice apartment
