@Jason Hunt this is a really tough question to answer as it totally depends on your goals (build wealth or reduce debt).

A registered agent will cost you around $50 per year with cheap online registered agent service (you don't need anything fancy for that as the service of registered agent is pretty basic).

Understand the fees involved and calculate the total cost for an entire year of management so you can compare the different managers.

Current rents total to $6600/month.

My lingering question is where you source each piece of information to plug in to the calculator.If I'm trying to evaluate the total income minus the total expenses, and as a result the cash flow and ROI, where do I find all the different values that go into it?

@Russell Brazil  I agree with Russ totally depends on what kind of real estate.. keep in mind that when you ask this on BP 90% of those on this site will gravitate to the only real estate is rental either sfr or small plexs or MF.. there are many many other types of real estate .take for instance in my mind one of the safest and most passive is investing in land in the path of progress.. pay cash and hold it.. nothing to it.. over time if you buy right or you buy a timber tract with middle age marketable timber species like Doug Fir or white pine  west  East  … these are very solid long term safe investments that you just make and sit and wait.some of the biggest money made in real estate though is land in the path of progress.. this keeps you immune from the ups and downs and risks of tenants.. 

If you would be so kind to share with me:How many properties do you manage, how many units in total?

Meaning that the multifamily must go into my personal name.If I quitclaim the property to the LLC after closing escrow on a commercial loan, I have heard such action could trigger a “due on sale” clause whereby my total loan amount could become due and/or I could be required to pay a prepayment penalty.Without the LLC, my tax structure is less favorable and I am exposed to personal liability.Any guidance on this situation?

The reviews online were pretty mixed.

Depending on the market if you did that with all quadplexes you could be at 16 doors in 4 years (not including traditional investment properties you may have aquIred) with a total of $0 in downpayments its an under used loophole in the system.
