Rent is a expense, not a liability.
Homes and condos are an asset, but for a variable portion of their ownership history, they are assets with a matching liability.
If you don't pay rent for the next month, basically you're out, but other than the time you lived without paying, some penalties and interest on the owed amounts, you're free, albeit potentially homeless.
If you don't pay your mortgaged, you'll be mortgaged, thus, potentially homeless, but depending on how much you market is valued on the market at the time it happens, and the balance of your mortgage, you can still end up homeless but still owing money to the bank.
