I own a mortgage company now that does both residential and commercial finance, but I spent years as a commercial banker with both big banks (First Union/Wachovia) and 2 community banks.

I have recently worked with a company that has an excellent offer.

Quote from @Nick Am: @Brett SynickyAnswers and thoughts below in Bold--> I am trying to setup a management company (LLC-B) and charge LLC-A management fees.

Better if the company has a lot of info in writing that you can absorb to minimize this.

How do I research the company?  

And yes, you could engage with a Turnkey company as well. 

Your first step is to contact a savvy CPA.You, as a Member of an LLC, by virtue of the LLC records provisions in the LLC law, have as much disclosure access, and more, than a shareholder of a public company.  

I'm still in the process of growing my portfolio, but have heard others 1031 all their smaller properties into a larger building and have a property management company manage, OR, set up a seller financing deal with another buyer that gives you the cash flow you desire. 

The concern with the DSCR loan is that I need to make the property present as though it's rented to individuals during appraisal (tough since it's a working rehab facility now) and must create another lease that shows the tenant as personal and not a company.

That is a good question, there have been companies that have had some in the past.
