Can I use different addresses for the FAFSA and my common app?

Are your schools CSS schools like UVA / W&M ? If so it’ll go deeper than FAFSA and CsS I believe will trump FAFSA and both parents will be included.

It’s highly likely at a UVA or W&M being in state will be better.

Did u run the net price calculator both ways ? Have your folks do.

UVAs is down but here’s W&M.
