California mortgage applicants have the highest average credit scores in the nation, according to a state-by-state study conducted by Mortgage Marvel, a nationwide online mortgage-shopping service. The average credit score in California is 755, a full 20 points higher than the national average.
“When I first looked at the results, I was a bit surprised that the results did not more closely follow the most troubled real estate markets,” observed Allen. “After we looked closer, however, we found that per capita income levels for 2008 as reported by the U.S. Census Bureau show a similar landscape with the West and Northeast at the top of the list and the Southwest and Southeast at the bottom. This led us to conclude that there is a closer correlation between the strength of the credit score and the per capita income of the region.”
