Investing in high cash flowing areas

[Scott Taylor]

I'm interested in investing for high cash flow (getting 20% cash on cash return and up).

Unfortunately this leads me to less than desirable areas.  In my case the areas seem relatively safe (C neighborhood, low crime- definitely not a war zone) but have declining populations and housing prices seem like they will only decline in the near future... (Specifically I'm looking to invest in northern PA around Scranton / Wilkes-barre)

My broker in the area keeps warning me of this - but is buying one of these properties really a bad idea considering I'm going Into this to maximize cash flow and not appreciation?
