Douglas Elliman agent Dina Goldentayer had a memorable June selling the two priciest homes in Florida's Miami-Dade County. The top sale was a seven-bedroom, 10,801-square-foot estate in Bal Harbour, north of Miami Beach, that traded for $42,973,750. Goldentayer co-listed the property with Joel Lusky of The Brokerage South Florida Real Estate. The second-highest deal last month was a 9,209-square-foot Miami Beach home that went for $25 million. It's now listed for rent at $65,000 a month.
