Miami tops U.S. luxury real estate market with most expensive home sales

South Florida rules the U.S. luxury real estate market — and a  new report  further cements our reputation as a billionaire's playground. The Miami metro area claimed the top three most expensive home sales in the U.S. last month, according to the brokerage Redfin. Why it matters:  Despite the growing threats of climate change, natural disasters and rising insurance costs, South Florida remains a magnet for the wealthy, Redfin found. Zoom in:  The nation's most expensive home sale in February was a  $49 million estate  in Manalapan, the wealthy village south of Palm Beach. Sticker shock:  The most expensive listing in the U.S. today, as of last week, is a  $285 million compound  fronting the Atlantic Ocean and Intracoastal Waterway, also in Manalapan. The yet-to-be-constructed project will include an eight-bedroom main house on the Intracoastal and a smaller beach house connected by a tunnel crossing South Ocean Boulevard, per the Palm Beach Daily News. The four-acre compound — next door to a property owned by  billionaire Oracle co-founder Larry Ellison  — will include a private dock, shooting range and private car museum, per the listing. By the numbers:  Palm Beach County claimed four of February's most expensive U.S. sales, locking out the top three spots with a  $48 million Jupiter mansion  and a  $40 million Palm Beach estate  on Billionaires Row. Miami Beach's North Beach neighborhood came in at No. 5 with a  $35.6 million beachfront abode in Altos del Mar  and No. 10 with these  Allison Island digs  worth $31 million.
