If you can’t afford to go there, don’t waste your time applying. But let’s first determine if you did the NPC correctly. You say your parents make $100k. Is that gross or AGI? Second, do they have jobs where they get W-2s? Or do they own their own businesses? Are they married to each other or divorced? As the poster above said, it’s not only income, it’s assets as well that are counted (although $200k in assets would not be considered “a lot”; there’s an asset allowance). Do they own a home? Do they own vacation property or rental property?
