Leo Kryss, a Brazilian electronics mogul, is suing Douglas Elliman, the real estate firm that facilitated the sale of his Miami mansion, after learning that the buyer was Jeff Bezos. Kryss sold the property, listed at $85 million, for $79 million, which he alleges was influenced by the realtor's assurance that Bezos was not the buyer. The mansion, located on exclusive Indian Creek, known as the 'Billionaire Bunker,' features luxurious amenities and has attracted high-profile residents. Kryss claims that had he known Bezos was involved, he would have been less inclined to accept the reduced offer. His lawsuit highlights how critical the buyer's identity was to his negotiation strategy. The case raises questions about transparency in real estate transactions, especially in high-stakes sales involving prominent figures.
