So much doesn't make sense.
If you're trying to buy a house, you really should be on top of all your payments. Student loans in particular are extremely forgiving, you can probably get away with only paying once every 60 days just to make sure it doesn't default .
Why are you buying a house if you're not trying to handle your $16,000 in outstanding student loan debt. She probably has to make a larger down payment to move in ?!
