To me it's crazy to borrow a big pile of money in the hope of returning a little pile of money. You might hope but you can't realistically expect to get a flying job soon after getting a pilot licence, let alone one that pays well enough to make the loan repayments.
Work hard doing something else and save the money first. Only after you've saved enough (plus a bit more), then start spending it, but only if you have a real job to fall back on! The reality is, unless luck goes your way it can take 2 years or more to land your first paid flying job. Can't imagine the bank manager waiting 2 years to start getting his money back.
