Despite the transparency created by the Internet information explosion, many celebrities and billionaires still try to approach home listing, selling and buying in stealth mode.

This week's Hot Property column looks at Madonna shifting gears from a privately shown "pocket listing" last year to an aboveboard one on the Multiple Listing Service to sell her Beverly Hills mansion. Listed at $22.5 million, the compound has been posted with just one aerial photo. Video guest Kofi Natei Nartey of the Agency in Beverly Hills sheds some light on why no one is talking about those secret interiors.

Also discussed is the Malibu estate that sold for a local record of $75 million and the name of the buyer has yet to appear. Why make the most expensive beach purchase in Malibu if you want to stay under the radar? It's a small town, after all.

For Sinatra fans, the chat turns to daughter Nancy Sinatra's 16-day turnaround from listed to sold in Santa Monica -- for above the asking price.

And a restored old Hollywood haunt, a onetime home of Samuel Goldwyn (think G in MGM), looks like a good catch for the buyer.
