Since you'll be an out of town landord, and based on what you're willing to pay, the advice you already have is good. I suggest you pick an area that you like the stats in, and buy your homes there. You'll need a local realtor for that. Find a good one and get tight with them. You can find property to buy much cheaper than your range, but the areas are transitional and the work is hand-on and you have a lot of turnover in tenants.
I'm a South Atlanta Realtor, so guess where my recommendations are....
Fayette County - Great schools, great living, close to Atlanta, never more than about 50 homes to rent ever. The smallest single family home rents for at least $1000 a month. But - not many foreclosures (never more than 10) Good luck finding anything to buy under $100K.
Intown higher end neighborhoods- Never much for rent in there, so you should be able to rent whatever you buy there. Good luck finding anything in your price range.
Coweta County - New hospital going in that should bring many jobs and create a greater demand for both long and short term rentals. Good schools. Good living.
Henry County - You have to pick your schools and neighborhoods, and they may take a little longer to rent, but there is good inventory on foreclosures.
By the way, if you've never done this before, I suggest you do it where you live so you can keep your hands on it.
