You might try searching the owner's name or address at GeorgiaPublicNotices.com for any recent foreclosure notices. Please note, however, that the owner may have brought the delinquency current, but it's worth a try. Also, you might try Googling the owner's name or address for any thing of concern.
As you may know, individuals here have been attempting to act as owners and collect deposits for the rental of properties that they don't own. Ask the landlord for an ID and then check the county tax assessor's office online to be sure that your contact is the same name that appears on file there before handing over any security deposits and take any disconnects discovered in your research very seriously. A real landlord would appreciate your conducting due diligence.
That's certainly not an all inclusive list, but these are steps that you can take on your own.
