So you are going to need about $35,000 of aid per daughter per year. You can calculate how much you will need in a university grant. A one-year package would include:
$2000 work study (you don’t get it up front, so cannot use it to pay bills the college sends)
$5500 total in direct student loan first year
That means you will need $27,500 in a university grant from each college.
The loans would be higher in subsequent years.
I think it’s a toss-up whether you’d get anything like that with your income and assets. Especially since nobody knows whether CSS schools will account for two in college.
The colleges do not care that you don’t want to sell the rental properties to pay for college. That’s viewed as a choice. The best thing you can do (probably too late) to improve chance for FA is to use qualified accounts for retirement instead of real estate. If your retirement assets were in qualified retirement accounts, those funds would not be considered in the FA determination.
