The family home of Needham Olympian Aly Raisman is up for sale. The 9,000-plus square-foot property, which is up for close to $2.8 million, has actually been on the market since August, but the realtor has stayed quiet about who lives there — until now. Laura Schindler said that when people have come to see the home and realized who lived there, they’ve said, “I should have brought my daughter.” After a while it became clear that the public may as well know. Realtor Schindler said the Raismans plan to stay in Needham but no longer need as much space. The property includes a tennis court and a pool.
