Real estate agent Elise Stern shared the Sherman listing with Judi Gottlieb, who was a close friend of the Shermans. It was Elise who showed the house when the bodies were found.
Although we don't know when the house was put on the market for sale, we do know that Stern advertised an open house on Nov. 28 (per the link below). Open house notices strictly for other realtors are not made public. Stern's notice of an open house appears to be a public ad, and I have to question if this was a private notification to other brokers, how would be made public on-line.
It appears that the Shermans wanted to sell their home as quickly as possible. I think this priority might explain any agreement for a public open house, and using a realtor's lock box. I agree that these measures are atypical for multi-million dollar for homes for sale. It didn't make sense, but KD's research seems to shed a light on how it might have come to be. jmo
The Shermans had two houses for sale as the ground was being dug up on their $30m new home. In addition to 50 Old Colony Road, they had bought another house in Forest Hill which they had renovated and put up for sale at the same time. Honey had decided that the house and lot was too small, and that is why they purchased the lot that was 3 blocks from their daughter Alex in the same area of FH. I can imagine that both houses needed to be sold fairly quickly to generate the cash to finance the new home.
They lived at 50 Old Colony Road while it was for sale. Their plan was "whatever sells first, we will live in the other until the new house is built". The estimated time for the new house being built was three years.
