I love this infographic from AHS and Realtor.org depicting the age of US housing stock. I can’t say for sure, but this feels pretty representative of Nashville housing stock as well. I actually think we’d have more in the 1940-1959 band (Donelson, Bellevue, West Meade, Crieve Hall, Charlotte Park, etc.) and less construction in the 1960-1979 band (Antioch, Priest Lake, Hermitage). What do you think? 
This is great Steph! Actually the stats make a lot of sense in my mind. Those years between 1940-1959 were war years followed by the immediate postwar climate. The track building industry was just getting off of the ground and inventing itself. Once the industry figured itself out….it really started humming along in the 60’s and 70’s and took advantage of cheap land prices and the general trend of families turning away from the farming life. Consumers benefitted by there being available housing and it was much more affordable. In our current economic climate, the regulatory hoops that builders/developers have to jump through coupled with scarce land have made housing much less affordable.
