That video is from the website marketing 700 Foxhollow Run in Milton, Georgia. According to a gushing piece in the AJC, the estate is owned by former Atlanta Braves’ pitcher John Smoltz.
The site City Data lists a $3.4 million 2003 sale price to Smoltz and his wife. I don’t know what improvements the Smoltzes made to the property, however.
According to a recent slideshow posted by the AJC, only one house in metro Atlanta sold for more than the Smoltz estate list price. An estate called Le Reve in Cumming reportedly sold for $9.5 million.
