Have you run the net price calculator at Harvard?
Does the net price come in under $20,000?
If it does then the most generous meets need schools may be affordable for you.
If it comes in over $20,000 are your parents willing and able to lend you the difference? And if so, have you run the numbers to see what the debt means in terms of payments?
If it isn’t feasible, you should target schools where full tuition merit scholarships are possible since $15-20k is the cost of room and board at a lot of schools or colleges within commuting distance if you can live at home.
