In another thread you said her mom earns ~$60k/year. Who’s planning to pay off this $80k in loans (+ interest)?
If you borrow this year but neither you or your ex borrow for years 2-4 she’ll have to transfer. Unfortunately, she’ll no longer be eligible for freshman grants.
If you and your ex refuse to sign her up for > $80,000 in loans she’ll have to consider more affordable options.
