OK, I will go slow here. The value of your house as an asset, whether you owe money on it or not, is the equity value less the costs (e.g. mortgage, maintenance, etc.)...although most wouldn't consider costs such as electricity and water, etc., to reduce the asset value.
The fact that you have expenses to maintain the asset may reduce the asset's value, but does not make it a "liability," it remains an "asset."
So let's say you bought a house for $1m and, due to CA real estate being what it is, it is now worth $3m on the market.
Let's say you have a loan of $800K on the house. The bank has an "asset" which is a secured loan of $800K against the collateral which is now worth $3m. But you, the "owner" of the house, has an asset worth $2.2m, i.e. the $3m value less the $800K you owe on it. Only you can sell the house, not the bank (unless the bank forecloses on you).
So contrary to what you say above, the house you live in is definitely an asset to you and the loan on it is an asset to the bank.
This is the MOST BASIC stuff about economics and budgets and value...indicating perfectly what I have been saying about you and economics...you know absolutely nothing.
