I personally have belonged to churches that rented space in retail space and other commercial space, as well as traditional buildings.

Now if I go with traditional financing and run my numbers with a 20% down, I don't see making a decent cashflow (should be atleast around $200) per door?

I'm happy to stick with the traditional security deposit for now. 

Yes, the rates are quite a bit higher than traditional banks.

I'm not a fan of traditional education and career path, though I know it's a well worn one.

Lastly, I wouldn't sell your house as there really isn't a better situation you can get yourself into from traditional means.  

At current vacancy rates ($9,866 monthly gross) I will not likely have additional cash flow built up to add equity, so my equity of $104k would be short of the $130k (20% of $650k) needed to refinance with a traditional lender.

In our area they have to do a perc test before installing a septic system and the results determine whether they can install a traditional septic (much cheaper) or a mound system.

There are also other ways to get cashflow through airbnb and short term rentals where a traditional rental would break even before taking appreciation into account.

That model is more of a traditional agent split model, with supporting broker services that are designed specifically for property management.
