Most positive cash flow cities, tax friendly states, Landlord friendly states?

[Brian Jackson]

I am in Southern California and plan to purchase and keep a long term rental property locally even though its cash flow negative and the landlord tenant rights aren't great because I know the area and can do repairs on it myself.  It is going to be cash negative for a long time but at the end I think it will appreciate significantly and have a strong positive cash flow.

That said before I sink my obligations into this I wanted to run the numbers against the most cash flow positive areas.  Cash flow positive rentals would not tie up my finances as much and allow me to turn around and buy more.  So with that said what are the most:

1) Positive cashflow cities?

2) Tax friendly states?

3) Landlord friendly states?
