Some schools don’t use home equity in their FA calculations, as you know. And of course the rental property goes on FAFSA, whereas the primary home does not.
Afaik, this (see link below) is the most recent home equity inclusion list, and it shows SCU does not include/assess home equity in their FA calc…of course you can confirm when you call SCU. You could also tell on SCU’s NPC if they hit home equity by running it with and without the home.
