That refi allows me to recapitalize and repeat the process.

There were many lessons learned in the process of my first investment.

For the BRRRR process I plan on using a hard money lender for the rehab process for the SFH's but what I'm not sure of is, should I purchase a duplex and rent one unit out and live in the other or should I just rent for now, not purchase a duplex and just purchase a SFH with cash and start BRRRR'n immediately?

Obtaining the FHA loan is great and you could repeat the process after about a year with the right lender.  

Here’s the situation (personal details removed):The tenant reached out explaining that they’re going through financial difficulties due to an ongoing divorce and lack of child support.

In other words, two financing agreements "wrapped" together.But the goal here would be for the 2nd buyer to close all-cash (to skip the financing process), would that still work? 

From day one I treated my involvement in real estate as a real business.This means, I had an advertising budget, a lead generating and follow up process, a back end process and money source and above all an experienced mentor.  

Top 3 reasons owners hire PMCs:1) No time to manage correctly2) No time to learn how to manage correcly: laws, documents, processes, etc.3) They're too nice and need someone to "save them from themselves"A good PMC can usually earn their fees by better managing the property/tenant than the owner, thereby:1) Increasing owners net profit2) Decreasing owner's time commitment, stress, headaches, etc.No matter what though, you should always plan to commit a couple of hours a month to manage your PMC.

Follow the lease and the laws in your state and start the eviction process.
