This is the student whose parents have been lying to them about their income/assets and wanted them to lie on the FAFSA. Yes, maybe the US property is just worth $400k and was bought for less and paid for with a $70k/year income.
I’m not clear from OP’s posts if the NPC results are based on all their income and assets or just those held in the US, so it’s difficult to tell if their schools are affordable. They need to be truthful on their financial aid forms, and I’d suggest they keep all the papers handy in case they’re picked for verification.
