A luxury mansion in Brookline, Massachusetts, has hit the market for $34 million, aiming to surpass the reported $32.5 million sale of Tom Brady and Gisele Bündchen’s former estate. Located near Brookline Reservoir, the 19,138-square-foot property features seven bedrooms, 16 bathrooms, a swimming pool, a private tennis court and Boston skyline views. However, Brookline’s slowing housing market could challenge the seller’s ambition to secure a record-breaking sale.
