I'm always amazed at the amount of answers that get posted. And, the LENGTH of some of them is pretty astounding!
I think it's a good idea for you to talk to a qualified lender to determine how this impacts your mortgage approval. But, from what I know to be true, your student loan is considered secured debt, so it's different from, say, credit card debt, so it's taken by the lender as "good" debt.
It will be taken in to consideration just like your other debt vs. your income to determine what they feel comfortable loaning you for a property purchase. Luckily, the mortgage industry has gone WAAAAYYYYY more conservative on their lending practices again. It's for everyone's good.
