Any advice on loans?

Hi, unfortunately, my state school offered me NO aid at all (tried appealing, which didn't work)….. I'm going to a T20 that offered me some money, as that is my cheapest option. With that being said, I might have to take out $30-40k in loans a year (for this year at least, but we're trying to sell our house right now, which should be able to pay off my tuition sophomore and junior year at least, since my parents are going to rent just an apartment now that it's just the two of them). I got around $8,000 from FAFSA. With the new federal student loan limit, that means I won't be able to borrow that amount. I applied to a bunch of scholarships, totalling maybe $30k, so I'm hoping to win some, and I'm still applying for more, though a lot of these come out in July. Is a private loan my only other option? I really want to go to college, but I have already committed, and this is my cheapest option. I also have a community college nearby, which my parents are not letting me go to. I am also a first-generation college student, so getting into the school that I got into means a great deal to me because it has so many opportunities and feeds into so many things. I plan to work in investment banking, and my school is one of the target schools (not sure if that helps). I plan to work summer jobs to also help fund my education. Any helpful advice would really be appreciated, please!

Edit: Also, I'm middle class (we make ~100-150k a year) but my parents inherited a bunch of assets, which is what I think screwed me over in terms of aid for my state school. Should we sell the assets?
