Tuition

I am an incoming student at U of M this fall. I was planning on filling out FAFSA earlier this year, until my mom started telling me she didn't want to fill it out because she didn't believe we would get any money since we own our house and it would be over the 75k in assets to qualify for the ZERO DOLLAR tuition from the Go Blue Guarantee. I tried explaining that we still get money towards tuition since we aren't exactly a rich family since the last time someone in our house was working was my mom for 4 months in 2022, and before that it was my dad nearly 6 years ago when my parents got divorced. Can I fill out FAFSA on my own next year? Is there anything else that can help me in my situation?
