/547 Lake Avenue, priced at $21,000,000, is under contract after 8 days, which, taking account of the time required by the lawyers to pound their chests and negotiate these things, probably means that a buyer appeared within 1-2 days of the house hitting the market. Hell, there might even have been multiple bidders.
Sited on 3.6 acres in the 2-acre zone, the house comprises 12,188 sq. ft.; toss in the 7,356 sq. ft. finished basement and you have 18,834 sq. ft. to get lost in.
That should suffice.
