HELP: Best Way to turn $400k into cash flows of $15k/month???

[Adam R.]

My goal is to generate at least $15,000 in cash flow (after expenses). I have about $400,000 in capital to start investing, and I am trying to decide on the approach that will allow me to do this in the quickest and most efficient way. I am thinking of investing in an area where the prices (and appreciation are lower) but where I can cash flow about $200-$300 per unit. I would attempt to BRRR some properties, but from some of the deals I have analyzed, I seem to be further ahead by investing in turnkey properties and putting 20% down. Based on these figures, I would need at least 50 doors to get to my goal.

Is there a better way to do this? Should I look at a higher appreciating market? 

I appreciate any and all advice and suggestions.

Thank you
