“No one has mentioned it yet but if your funds are in a 401k and you are not yet 60 (or is it 59.5?) do not take that money out to pay for school! You will be taxed and have early withdrawal fees. So $100k from your 401k would only be $50k to $70k.”
Great point, OspreyCV22. The other thing that few people add is that on top of taxes and early withdrawal fees (usually 10% in fees alone), you may well put yourself in a different tax bracket with the additional income, losing deductions you would have taken.
Just something to be aware of.
