OP - first off, congrats on being a great student with an impressive GPA and test scores. This clearly means you are smart enough to be able to figure a lot of things out. And as a junior - you still have several months before you have to apply.
Sorry to hear that your family situation is - shall we say - complicated? You mention that your Dad earns $75K - 80K but it is not clear how much your mom earns - if any - or is she relying on child support? If she is earning 60K then you are right not to expect a lot of need based aid - but it is still very possible.
If you are fortunate to be accepted at the 100% full-needs met schools - and your scores and GPA would say that you’re competitive for - then it wouldn’t surprise me if they took into consideration your family’s two-household situation, and you might still qualify for FA. These schools require the CSS profile - but the good news is that your father communicates with you and presumably would be willing to help provide information to complete these forms.
Just because the needs met schools give a full ride to families under $60K, they still provide a LOT of aid to many families earning under $120K. And all of these schools are more than happy to help answer questions, and they have undoubtedly seen situations like yours before. They will answer questions before you apply.
It is possible that you might get enough aid so that, with a modest amount of student loans and/or work study, you will be able to attend a great school.
I am confident that you will figure it out - best of luck to you!
