Also, I think this could not be used as secondary financing. 

A flat-rate PM fee incentives keeping things as SIMPLE and EFFICENT as possible.

Also, how would I analyze the numbers for this deal, because there are various ways it could be used, either separate or possibly all together for a larger group.

Inherently the steps are the same as if you were purchasing with financing save potentially less closing costs and ability to close sooner (if needed).The terms of your offer (ie -contingencies, closing cost splits etc) will determine what is different. 

Look at photos, and look for homes that look as similar to yours as possible, in quality, condition, style and size.  

With your first investment, you want to try and minimize risk as much as possible.

I do have a second unfinished property in GA that I can possibly leverage.

Now we are mostly scaling our business with larger communities but I've used many different creative finance strategies including seller finance, private lending, hard-money, collateral from other properties, and lease-options. 

Quote from @Blair Ross Jr: Is it possible to purchase SFR or duplex rental with less then 15% out of pocket?

I haven't spoken to the county yet, but will make that phone call today.As far as financing -- I was leaning more towards getting a business line of credit or using a business credit card and rolling it over to interest free cards.
