The credit union have never refused me a loan. They're always more than willing to accommodate in times of financial difficulty. I save weekly with them by DD and deal with them over the phone; the staff are so friendly, so understanding and generally a pleasure to talk to. Got my car loan at 5.7% and was just approved for another small loan at the same low rate to finally clear the credit card (I know, I know!). You can borrow up to 2.5 times your savings, plus you continue to save, so there's a sense of security there for small-time earners. Perhaps some of you disagree with saving while borrowing, but the emergency fund is always there, which is a great comfort to some.
Put it this way, I'd rather pay loan interest at a reasonable rate and continue to save a small amount with a lending institution which provides a friendly, efficient community-based service, than be crucified by a bank. If I miss a payment the worst thing that'll happen is I'll get a friendly phone-call gently reminding me of my obligations.
Sure, it makes no sense to leave a large sum of money on deposit with them, but for someone on a low wage or for someone looking to finance a course/holiday/home improvements, they're pretty hard to beat. Low interest, no penalties for early repayment, security for your loved-ones in the event of your death/incapacity. The key word is CREDIT, they're an excellent option for borrowers.
