Yeeesh. In California, the equity in your primary residence and one rental house could be well over a couple of million!
USC also requires the CSS. They may want to know the equity you have in every car the family owns, will definitely want to know the equity in every home the family owns. If the business is sold, they’re going to want to know how much it was sold for - this would be reflected on the income tax filings. And if it was sold for a profit, and you’re not showing where that money went, they’re going to want to know what happened to that profit.
Long story short, they might not give you a cent, because of the assets. Maybe they will, but maybe they won’t. Definitely apply, be totally truthful, and see what you get. But also make a backup plan, for a school that is financially feasible for you.
