Does anybody know what the "Debt Use Index" is?

[Kevin Blair]

Hi All,

I've spent the past 3 months working for my Uncle's wholesaling business in Arkansas and am now in the beginning phases of launching my own in Chicago.  

I heard of something called the "debt use index" from one of his business partners.  Basically, it's an index that gives the average amount of monthly recurring debt obligations that individuals in a certain area have as a percentage of the area's average income.

I'm struggling like crazy to find it.  I see having that info as a big help in determining which towns/neighborhoods and what types of houses I should be attacking in that area.

Has anyone heard of something like this?  He's quite the redneck who likes to develop his own language for things, so I'm thinking "debt use index" might not be the technical term.

Thanks in advance!
