There was a recent thread that included credit scores.
Insurance companies also use credit scores when determining auto and
home owner insurance rates. Another good reason to get your credit
report from one of the three credit bureaus every four months. (You can
get one report free from each of the three bureaus every year - if you
do this every four months, you have the best chance of spotting
unauthorized activity.)
http://www.annualcreditreport.com is one site that lets you get the
report free.
Other recommendations for the August issue of Money magazine (p25):
keep your oldest credit card - creditors like a long history of credit,
at least 5 years, 10 is better with the same card.
don't apply for lots of credit at once (multiple inquiries for auto or
mortgage loans count as one inquiries over a 45 day period)
get rid of cards that you don't regularly use - having too many cards
decreases your credit score
Just some thoughts.
