What grade is the student currently in? What state? What are her stats (ACT or SAT, GPA)? What major or field is she interested in? Does she prefer urban, suburban, or rural? What’s a rough estimate of what you could afford? Remember, by posting these, it’s still anonymous as long as you don’t attach local or personal information. There are a lot of people in your state and a lot of students with the same stats/affordable figures, etc.
Pending those answers, CC parents can likely point you to some more affordable schools to check out. If she has the stats to be considering prestigious, there could be decent options - just not those without merit aid.
Definitely run a NPC at one or two of the prestigious colleges she likes because many parents can be amazed at what some offer if an income is <200K. Of course, the “trick” is getting in to any of these colleges, so you’ll want others on the application list too - even if you could be full pay.
