The equity value of your house does not put money in your pocket until you sell it and therefore equity value is not an asset. Borrowing against your homes equity does not change that fact. It only increases the assets of your lender. The fact that you have expenses to maintain the banks assets as a condition of their $800k loan to you are contractual (PMI, taxes, HOA/mello roos) and increases your liability for the benefit of the banks asset, your home. Yes it does remain an asset, but at this point notice the direction in which the money flows for 30 years. It's not toward you and you are okay with it because you want to build equity. But I know how tempting it is to think that you own that equity. You don't. You have access to it at a cost.
So contrary to what you say above, the house you live in is definitely a liability to you and the loan is an asset to the bank when you consider who pays the bank.
In your example you have a loan of $800k. What was the purchase price?
Dude, 3 strikes you're out. maybe take a class or something. In my example (which is over your head), my asset value ($2.2m) is worth far more than the bank's asset value (a payable $800K loan earning a mortgage interest rate). Do you really not know this stuff? And yet you cite articles and shoot off your mouth like you know what you're talking about?
I had a feeling you were a nutcake in a cubicle...now you've proven it.
