Advice on my investing plan!

[Jared Yates]

Hey guys. I'm a new investor in Louisville Kentucky and I'm looking for input on my investment strategy. For reference, I'm a full timE paramedic. I cUrently have no rental properties or experience. My current budget has allows me to save $1000 a month for down payments. I've built up a pretty good down payment including 14k cash, another 15k in a Roth IRA, and a 10k emergency fund.

 Currently my strategy is to focus on cash flow. I want to buy a quadplex and try to get $150 a door. That would put me at 6k a year that I could combined with my savings for another down payment next year. That would give me progressively larger down payments every year. I would like to acquire another similar property the second year and then another the third year.  according to my math, once I hit 20 units and if I'm making $150 cash flow on each unit, I should have enough  cash flow to retire. 3k a month. Btw that would make me 31 when I retire which is my ultimate goal.

 With the resources I have listed and considering the Louisville area Marketplace, what would you guys recommend?  Does my plan sound realistic or am I about to make a tragic mistake?  All input is welcome!
