I have $150K and want to start getting a property every 6 months

[Taft B.]

I have $150K in cash. I want to build a portfolio of rentals (target 10), one every 6 months or so, and I am brand new. What is the best way to use that $150K? My credit score is 800, I currently rent, no other real estate or assets (other than 401K). I am leaning towards turn-key because I have a great job that takes most of my time. Should I spend that whole $150K on the first deal, hold some back for future deals? other strategy???
