Credit repair scams.

This is one of the more recent credit repair scams

-- and one of the most costly. Con artists dangle the promise of much-needed money or loans in front of desperate consumers as an incentive to pay, pay and pay. Some scam outfits mimic credit counseling agencies, others imitate mortgage companies. But all they do hit you up for money (sometimes several times) then leave you empty-handed.

And since there are genuine community nonprofit groups that help educate consumers and help with affordable housing issues, scammers may also try to imitate that business model. The best advice: Hold onto your wallet, and be wary of any big promises or fast fixes. Reputable organizations focus on education. When in doubt, do a little reference checking on the Internet, with the state regulatory or consumer offices and with local offices of nonprofits and community groups you trust.
