To @Andrew Kerr 's point and yours about regulations and Airbnb-friendly cities ...

I don't know anything about Atlanta or College Park, so it may be a different regulatory environment down there. 

She had an idea about a collaborative environment for other therapists.We also have 800 sqft of area on the 2nd floor that hasn’t been fixed yet and therefore no CofO for that area, but could be renovated and obtained in under two months and about 10k in expenses.

Firstly - this is likely governed by state, county and even municipal law / regulation so check in your jurisdiction.One question - Does your lease state that the 'Deposit' is for 'Security' or 'Last Months Rent' (LMR).

In the abscense of a sewer officer, find out who regulates on site sewer systems.

Lending is a highly regulated industry and most things are cut and dry with what they can and cannot do.

If you are investing in a certain area, be aware of the rules, regulations and laws governing real estate in your area.  

Adding on isn't always good, I've seen some crazy things in rural areas where they have less regulations on permits, etc. 

I would talk to agents that you have dealt with or know, and ask them how their office environment is.

Government regulation from one agency causing consequences against another agency, when each agency originally intended to target the "rich landowner".
