Small businesses are very important customers for banks today because there are more of them than ever before and each and every bank is fighting to get them.

A lot of people get a home equity loan and do it on their own, short of going to a credit counseling agency. You can consolidate your credit card debt and have a lower monthly payment that will maybe get you through a squeeze.

Banks have various sources of earnings. If a bank is large enough to have international operations, it has evolved enough diversification to counteract those losses.

Not every place right off the bat will offer you a good rate. One company may offer you 15 percent. Another may offer you 11 percent.

Think about the relative merit of variable rates versus fixed-rate credit. Locking in a fixed rate now gives you a great deal of comfort. Even though the lowest rate might be a variable rate, those could start to climb again next year.

If you don't trust yourself with that much credit, you should ask that the limit be reduced.

Bank loans have pretty attractive interest rates these days. Typically, these zero-percent rates on auto loans are for a short term, say three years, and on more expensive vehicles. People end up buying the car, but use a bank loan to do so. Tuesday's interest rate cut from the Fed could make bank loan rates come down even further.

The broad trend among banks is to service customers almost regardless of their credit standing. They do not want to turn a customer away, particularly if it's a customer with a checking account or another relationship.

Any change in rates on home equity lines is directly related to the actions of the Fed. On average, their rates are 1 percent over the prime rate, but some banks even offer home equity lines at the prime. Home equity lines are probably the cheapest way that homeowners can currently borrow money.
