Don't always consider yourself "over a barrel" even in the worst situations. Before you do business with some lenders or credit cards, be clear of the downsides, too. There are plenty of good companies out there who will deal fairly and honestly with you, even with damaged credit. But unfortunately, there are other lenders and card companies that are considered "predatory" in nature, meaning they will rake you over the coals, charge you outrageous fees, and in short, rip you off when you can least afford it.
My picks for lenders and cards to avoid:
Mortage loans: FULL SPECTRUM LENDING (a division of Countrywide Home Loans). Bait and switch artists, hidden penalties, broken promises. Their reputation is poor all over the internet.
Credit cards: CONTINENTAL FINANCE. Incredibly high fees, many recurring fees associated with unsolicited credit line increases, etc. Very difficult to identify corporate leaders and virtually impossible to reach their main offices.
Another credit card: ANY card from CompuCredit. Just about the most ridiculous phone system I've EVER tried to negotiate.
Let's have some more opinions, please.
