I disagree. Atlanta has literally thousands of midcentury modern homes. From all price points, $150,000 to $2,000,000 plus!!
The greatest concentrations are Northwoods, Northcrest, Briarcliff Road between Shallowford and Clairmont. These houses range in price from about $150,000 to $450,000. Some of the starter midcentury homes in Northwoods have not been molested and are a steal in the $150,000 to $225,000 range, some have .5 acre lots. Amberwood has spectacular midcentury homes designed by Green who was a student of Frank Lloyd Wright., one home recently sold for over $1,000,000. The homes in Northcrest are larger and are a bargain as well in the $200,000 to $350,000 range. Both are not in "trendy" neighborhoods, yet both are relatively safe and are in secure neighborhoods and both are located near the international business's along Buford Highway. And both are very convenient to Downtown and Buckhead, so they are hidden treasures.
There are many others, as well, spread thoughout the city. Sandy Springs and Buckhead have spectacular midcentury homes in very good condition. And they can sell for $500,000 to millions. Unfortunately, a lot of these houses have been lost in high end neighborhoods because of new constuction. One good thing about the present economy is not many new homes are being built, so it's a blessing in disguise for our midcentury treasures.
