City-data has info on businesses it knows about, but doesn't seem to indicate their status as being major employers in an area.Before investing in an area, I'd like to understand the employment base so as to assess the potential renters in that area and the stability of their source(s) of income.

How they take care of the inside of their car is a good indicator of how they'll treat your house.

I believe you indicated it your last post that they may be familiar with the “system “.

I found someone I know on RealtyTrac.com indicating their house is near foreclosure or in it.

Make sure those indicators dont exist and you might be fine.

Also, cap rates will change submarket to submarket, so to go on Kansas City alone would not be a great indicator either.

If the cash flows are split in a waterfall structure like you indicated, a majority of the cash flows would go to the GP.GP has to pay out the hurdle essentially.

While making 100k plus annually and have hard time raising 1k is an indicator of poor personal finance.

This is a clear indication they place their own personal needs ahead of paying money they owed to the landlord. 

Driving the neighborhoods is definitely your best indicator, crime heat maps, etc.I don’t know Lake Worth that well, but I believe the worst areas are south of Lake Worth rd, west of Dixie Hwy.WPB, worst areas are just north of the CBD, again west of Dixie...like 7th st up to 25-30th st.
