I would advise, if your goal is to generate passive income, to churn that income from your flips into cash flow producing properties, then rinse and repeat. 

I found 3 properties for sale in Lexington (2 4-plexes and a duplex) I'd love to own there, all rented out, producing nearly $4k positive cash flow per month.

The multi-family investor market has been flooded with owner/occupiers who see house hacking as a viable alternative/income producer.3.

I have been wondering about this for a long time, and as long as I am confident in the properties ability to produce positive cash flow, I don't see why not?  

Jones in these areas are also a lot less expensive than LA but could produce a great deal of streams of money.

agents can set you up on top producer type program  put in your wants .. and you get e mails daily of new listings that meet your criteria... giving out your MLS code to another is a bad bad thing for realtors they can get banned and fined 20k anyone doing this is taking huge risk .. not many will do it.I have seen agents give their assistants access which is allowed but customers no way

That simple, one that produces the income to afford a PM.

I want to do this the right way to build a portfolio that produces passive income and a friend told me about Bigger Pockets.

That would, of course, be ideal provided that it still produced cash flow.

I am trying to make the case that looking outside of this complex will produce better cash flows and would allow my brother and I to confidently invest in.
