“The market is better and the people that have put off selling are seeing what things are selling for.  First time for three (on Elfreth’s Alley) that I can recall in 25 years that I have been doing it — at one time on this block.”

McCann describes the features of 123 Elfreth’s Alley, currently on the market for $795,000: “It’s about a two hundred year old home. This is the baker’s house. It’s about 2,600 square feet.”

McCann says the other two home prices are $850,000 and $650,000. Owners are not permitted to change the exterior in any way but can remodel inside to their heart’s content.  He sold two homes on this block last year.
