FAFSA is for federal loans. While some OOS do provide need aid, most do not. Two promise to meet full need - UVA and UNC.
To find an affordable school, you’re better to apply to colleges that will meet your budget or can get you to your budget via merit aid.
PA has lots of great schools too - WCU, Bloomsburg, Millersville, etc and the PSU and Pitt branches.
