Atlanta has a lot of Fortune 500 firms located there. 

I live just up the road from Kennesaw in Canton and host the meet-up that @Jorge Borjas mentioned.

I've furnished and hosted at 10 different properties, from studios to 2-bedrooms.

I have my license and practiced actively in commercial brokerage for a few years before leaving the firm to focus on my investing activities along with others.  

You could do what the guy suggested if you want to, or you could just spend $100 +/- $50 and buy a list from a whole host of online vendors including ListSource, Listability, US Lead List, etc.

If you were to personally borrow from your 401k, you could not combine that money with an IRA on a project as that would be self-dealing.I'm not sure where/how you setup your IRA, but if the firm you are working with cannot easily navigate you through what I have described above (which unfortunately, may be the case), then you might want to look for an alternative provider.

I am currently in the process of getting my CA architecture license and am working at a firm full time but quickly discovered the 8+ hour work days in hope to retire at 65 is not for me.

I currently work in an architecture firm that deals with developers all the time with the same concept at grasp.  

As an Architect I can tell you that 10 days may be fast to prepare biddable drawings for an addition, but if it's a small firm or sole proprietor architect doing the work, they can do it even faster.

However, I am a firm believer in investing in any market.
