Arizona has broken into the top 10 when it comes to mortgage fraud.

The ranking comes from an annual survey by the Mortgage Asset Research Institute. The data comes from the country's biggest lenders. The rankings are based on the number of mortgage fraud cases per total number of home loans.

Arizona jumped from No. 23 to No. 7 on the list, the biggest jump in mortgage fraud from 2005 to 2006. This is the first year, Arizona has had such a high ranking.

Analysts say that jump is the result of s high number of cash-back deals, in which people get a loan for more than a home is worth and keep the extra money.

According to lenders, that kind of scam not only inflates home prices and costs the lenders millions in bad loans, it also means recent buyers might owe more than their homes are worth.
