Regarding budget, if you and your parents can contribute up to $10,000 per year, then the budget based on her student contribution would be:
about $10,000 with no loans or work
about $15,000 with federal direct loan or work
about $20,000 with federal direct loan and work (the stretch budget)
It looks like Texas public universities’ in-state list prices are at the very edge of affordability based on the above. Schools with full tuition merit scholarships should be within the above ranges. Full ride merit scholarships are obviously better.
