This should have been part of post #1, not post #129. These are big assets that go into the EFC. Your parents can have a fairly modest income of $60k and having 3 additional houses will kill the EFC every time.
So there you have your answer as to why the EFC is so high.
Now the issue shifts to how much your parents can afford to pay for you and your sisters next year. Start looking at local scholarships. It looks like you will most likely be attending college close to home in NY, so if you can find some local scholarships that might help you. Elks club, American legion, local businesses, churches often have them that can only be used in the city or state.
If you really have no hope of affording Syracuse or NYU, you are wasting $100 bucks. You might be better off buying $100 worth of lotto tickets.
