Im looking for guidance to make my big entrance into real estate.

[Henry Koon]

I am currently a 3 house veteran in real estate.  I am going to be acquiring a large sum of money thru smart investments that i have made.  I have done my research and have researched my farm areas.  I cant decide whether to buy and hold 10 - 15 doors or if i should keep flipping.  From the research i have done it seems like the market is either saturated with investors or the selection of properties are few and far between.  What would be the best move to get a strong income from either strategy? I appreciate any advice in advance.
