For example if you have a total of $550,000 in (mortgage) debt, and the market value of your properties, that you can actually sell them for, total $1,000,000, then your equity is $450,000.
If you have credit card, car loans (or any other debt owed) of $10,000, subtract that from $450,000. Then, your net worth is $350,000. Please come back & update this as your wealth grows.
