It's time to take care of business. Here are answers to some of your recent questions. Anyone who wants to throw any other issues into the wash, please put your questions in the box at the right.

With no notice, three of my credit cards slashed my credit limits by more than $10,000 each. Then they doubled my rate and changed from a fixed rate to a variable one. Is there anything that I can do?

You could call your credit card company and make the case to show your situation hasn't changed. But honestly, I don't believe it will work. Credit card companies are doing these things to good customers everywhere. I don't believe they care what the reaction is. What I'd do instead is start shopping. For a better card or set of cards.

Where can I find textbooks to buy used or at a discount

Popular sites for buying and selling textbooks:
half.com

Amazon.com

Can you buy a house if you do not have a job?
-Leanne

I hope not. Isn't that part of how we got into this mortgage mess, because people who couldn't afford to repay mortgages were allowed to borrow anyway?
Seriously, though, there are cases where you can buy a house without having a job. If you have enough cash. Or enough assets that are producing income that will cover the mortgage, a job isn't always necessary.
But a loan that doesn't require proof of income is very hard to get these days.
