ETA…
You got a lot of good suggestions on this thread.
What income do you think is “middle class”. Make sure this is the gross income you earned…it needs to include all contributions to tax deferred retirement plans for the tax year of your financial aid forms.
You say you can pay $30,000 a year. And that Miami in Oxford OH is your daughter’s safety. That’s a good start. I’m going to second Denison. I think she would get good merit there…worth a try.
What schools is she now wanting you to consider? Would she consider any of the all women’s colleges, because some give merit aid, and some decent need based aid for “higher earners”.
Have you run net price calculators for any of her new schools of interest?
