40 Greenough Ave. was on the market for $2.475 million as of Friday, May 30, 2014.
A Sumner Hill mansion — which the owners knitted back into a single-family house after it had been split into three units — is on the market.
The 14-room house at 40 Greenough Ave. was restored by owners Diane Pienta and Dave O'Donohoe, as they explain in a video about the house.
[selfie]"Even though it's sad for us," Pienta says in the video, "it's time for it to be filled with new life. It's a happy home."
