Which gives more aid: single parent with $150k income or 2 parents with $200k income?

Parents are separated but in really good terms. They live in different states. Mom makes $150k gross income and supports 2 kids on her own (no child support). Mom pays $1800 in rent but sends $2k a month to Dad towards the mortgage and renovations of the house they still own together. Mom files taxes as head of household.

Dad does not work but receives $50k gross passive income. Dad and Mom share one bank account but Mom never uses it.

When we complete FAFSA, is it better if we list the income of both parents as a household of 4 (2 different states, 1 mortgage and 1 rent) or just Mom's income as a household of 3 (one rent and a mortgage payment for a house we dont live at)?
