According to the Internet, a person who studies trains is called a ferroequinologist, or in some circles, a railfan. That being the case, this newly listed Candler Park condo is a bona fide ferroequinologist utopia! Its massive patio overlooks the rail lines of DeKalb Avenue, providing what must be consistent blasts of screechy, whooshing MARTA ambiance. Some people like that sort of urban soundtrack; others call it the bane of their existence. Perhaps the location figures in to the relatively cheap $269,900 asking price (plus not-too-bad $278 HOA fees), which bags a spacious (nearly 1,400 square foot) two-bedroom, two-bathroom condo with a dramatic wall of windows. A block east of Fox Bros. Bar-B-Q, the building is a 2008 component of the Axis development, where brand-new townhomes have been undergoing price chops lately. Inside, there's a slick kitchen and spiral staircase leading to the whole-floor "master retreat," which has room for an office. The agent is quick to point out the iPod surround sound and double-paned windows … all the better for noise-insulation.
