Beltline, Silver Comet and PATH - value adds to investment properties?

[Jeffrey Kingman]

New to RE investing. 

My gut tells me that the continued development of the Beltline, and it's ultimate paved connection to the Silver Comet, are lifting values within walking (1/2mile) of said trails. With that thesis, do the outer communities along the Silver Comet forecast to experience a bit more elevated "lift" over time as a result of the connection completion with the Beltline (Smyrna, Mableton, Powder Springs, Hiram, Dallas, etc)?

a) is it a value add over the long-haul (10-20 years)?

b) is it a value add for LTR homes within a 1/2 mile of the Silver Comet?
