Celebrity real estate power couple Josh and Heather Altman from "Million Dollar Listing: Los Angeles" are facing challenges in the housing market, including the impact of Measure ULA, or the "mansion tax." This tax imposes charges on high-end property sales, affecting not only the rich but also developers, investors, and homeowners looking to retire. The Altmans are witnessing buyers shifting to areas unaffected by the tax, like Beverly Hills or Manhattan Beach. Amidst these changes, they are expanding their business into areas like Newport Beach and offering advice to buyers and sellers. With their experience and expertise, the Altmans are navigating the complexities of the market, balancing family life, business, and the evolving dynamics of their hit TV show. Tune in to Bravo's Season 15 of "Million Dollar Listing: Los Angeles" to see how they adapt to these challenges.
