Seller Stands Ground on $125 Million Mansion

Built of imported limestone, and modeled after Louis XIV's Vaux le Vicomte palace, the estate includes multiple gardens, spas, pools, a nine-car garage, a championship tennis court, a 200-person capacity ballroom and a 50-seat movie theater that might make a trip to the local AMC(AC Quote) Cineplex obsolete. The interior features Italian marble walls and a more-than-minor use of gold as a décor touch.

But a recently available property may give potential billionaire buyers of the Fleur de Lys (rumored to have included Mariah Carey) another option to consider.

Though CBS Paramount's(CBS Quote) rebirth of "Beverly Hills 90210" may not be gaining as much buzz as was once hoped, a recent entry to the market, the Holmby Hills mansion once owned by television impresario -- and original "90120" creator -- the late Aaron Spelling, is. That home is said to be on the market for $150 million, but the listing is being shopped privately with negotiations kept from prying eyes. If that price holds, however, it will have the distinction of being the nation's most expensive home on the market. It also stakes its claim as the largest home in Los Angeles County.

But where do this high-profile properties fit within the real estate market for what may be America's most-desired zip code?

According to Bennett Carr, one of Beverly Hills' best-known realtors, a market adjustment is under way, but the news is not all bad. Though he declined to comment on those particular properties that have refused to yield ground with their asking price, he did say that having a realistic view of what the market will bear is crucial.
