Question about Current market value of investments

Hi everyone
Here is a stock market investment my dad told me which makes me confused.
At first, he bought the stocks which the market value is 360000, then mortgage these stocks to broker to get 200000 loans, use these loans to buy more stocks wihch the market value is 200000. Now he has 560000 total market values of stocks as his investments, at the meantime his debt is 200000. For this situation, how to fill the CSS Profile at the ‘Current market value of investments*’ section, it should be 560000 or just the net value 360000?
Thanks

It should be $360k. That’s the value of the portfolio if he were to liquidate it.

Thank U soooooooooo much : )

He just gets that figure from his brokerage, e.g. vanguard will have a landing page for the portfolio value as per real time.
