Once upon a time, things were awesome in the housing market. Then, in September 2008, Lehman Brothers collapsed and the economy with it, no sector in a more high-profile, dastardly way than real estate. This floor-through 3-BR, 2-BA on mighty Marlborough Street is a reminder of that prelapsarian age (heck, given its age—its building went up in 1890—it's a reminder of the original Gilded Age). The last time it traded was in August 2008, right before the fall. Then it was $1,250,000. Now it's $1,575,000.
