I would rarely, if ever, recommend more than 30K of student loan debt for undergrad

To some of your points:

  1. You can’t compare student loans to mortgages. Mortgages are secured loans, so the bank is taking less of a risk. Student loans are unsecured, so are much closer to a credit card than a mortgage. Credit card interest is often 15-20%, and no one blinks at that. (I think that’s not smart borrowing either)

  2. loans are usually not dischargeable, but more have been lately. Still not a good plan to ever think bankruptcy is the way out of your debts, any debts.

  3. the government can take your tax refund IF you are in default on government loans, not just if you owe money. So don’t have a tax refund if you are in default. Tax planning can avoid this (I can calculate my refund/amount owed to wit in $50). This is true for Stafford or Perkins loans too, the first dollars you borrow, not from private lenders. Don’t get into default.

  4. Parent plus loans belong to the parent, so the parents aren’t co-signing. Social security, or any government payment due to you, can be taken if you are delinquent on a government obligation, so if the student still hasn’t paid by the time SS kicks in, it can be garnished. There are 65+ year olds getting hit for loans they have never paid back.

Absolutely agree that borrowing should be kept low, and often the solution is to pick a cheaper school, not borrow more. I don’t think I’ve ever seen on CC that it is a good idea to borrow more than the Stafford loans, or more than $30k, and most want to even avoid that. Not for a dream school, not for Harvard, not for art school. Set a budget and stick with it, and plan to pay back the loan, not default or assume it will be forgiven.
