The 1,848-square-foot Second Empire Mansard at 19A Spring Park Avenue in Jamaica Plain last traded in March 2012 for $315,000. The new owner then set about rehabbing the 3-BR, 1.5-BA spread dating from 1880, retaining a lot of that historical charm but updating the house significantly (roof, windows, central air, plumbing, etc.).
The result is a kind of sleek museum piece, complete with a chef's kitchen, wraparound deck, and two off-street parking spaces. The total tag for the three floors and more in busy, busy JP? $899,000.
