You've taken "Rich dad, poor dad" too literally it seems. A house can be an asset or liability, depending on its use. If you live in it, it certainly earns you something, it replaces the need for renting a space to live in. If you own it and don't use or rent it, it can be a liability if it's not even a suitable investment vehicle (e.g. with stable or falling prices).
> A house can be an asset or liability, depending on its use.
A house, per se, is an asset. It may or may not have liabilities attached to it. (Or produce maintenance expenses, which is a different thing altogether.)

You seem to have confused a depreciating asset with a liability.
