The biggest step I would take is contacting a local real estate lawyer to review the contract you have gotten.  

Anybody who says or thinks otherwise is advised to talk to both their CPA & Lawyer for clarification.

If you're going to get hard money, hire a lawyer to review the contract.

It would be really helpful if anyone could point me to a local real estate agent/lawyer in the City of Kennesaw.

Unlikely, but worth a try.Time to lawyer up and figure this out.

Everyone is an individual -- there are good cops and bad cops, good doctors and bad doctors, good lawyers and bad lawyers...and their status could be affected by a multitude of reasons.

I mean, should I look for a lawyer or special company for that?

I know a few agents in my area that I avoid because they try and do things like this  most all RE contracts these days have mandatory mediation.. so no need to lawyer up if you dont want to.. there is a fee for mediation but thats where 99% of EMD squabbles go and get settled.

Maybe ask a lawyer who's familiar with these cases, but my guess is you are probably free to boot this guy.

Come up with a polite script to ask multi family landlords that have units for rent and politely ask the seller if he or she would be willing to let you sublet the property...Now here is where you can get creative...Most people are probably going to say no, but if you offer them something in return that makes their life easier....paying for property upkeep, signing liability forms over to you (talk to a lawyer) maybe paying him bi-monthly rent to give him/her a warm fuzzy.
