WHERE to buy cash-flowing rental properties (Houston area)

[Jordan Decuir]

I'm looking to start picking up single-family rentals in the Houston area, and am curious as to the types of areas in a given city that yield the best prospects for cash-flowing SF homes.

What should I be looking for in terms of demographics that may represent better prospects for cash-flowing properties?

Should I be looking in areas where the "working class"/blue-collar workers represent a large proportion of the population?
