North Metro Atlanta, anecdotal here but I have read similar. There are a lot of failed/incomplete subdivisions out where I live. Recently an investment group bought the last 11 lots in my 54 lot subdivision, they had been empty for three years.
Within short order 11 new homes were built and are being rented. There are two different companies contracted out to rent these homes for around 1300 a month. Single family only, background checks, and a host of rules. Two other nearby subdivisions are trying to sell their incomplete lots but the builder for this group told us the appeal of ours was no pool or tennis courts. Toss in large homes, existing were 3800 to 5200, large lots, and it was ideal for their investment. The new homes are 2400 square feet but fit in architecturally.
With the possibility of an airport expansion in Paulding I suspect NW Metro Atlanta will see a large expansion in rental housing. Contracting out to build homes in numbers of near a dozen does save good money
