I’m trying to say that under mortgage, a property isn’t your asset. It’s a bank’s asset. The mortgage is booked under asset side on the balance sheet of the bank. It cannot be booked as an asset on your side. The economy wouldn’t balance. Until you actually paid off stuff the home is a liability. You pay money on it every month (negative cash flow) and that cash flow accrues to the bank (positive cash flow). I don’t know in what definition an asset produces a negative cash flow. It’s a liability under most definitions. Maybe I’m wrong. I’m not an accountant.
