A search of King County property records showed that since the June 2007 sale of his previous residence, Barton hasn't purchased property under his or his wife's name. Is he renting? Zillow's Amy Bohutinsky says Barton does own his own home, which a Seattle-based tech reporter says is in the city's Madison Park neighborhood. He may well have bought it under a trust.

If so, it's the first time he's chosen to do so in years of owning Seattle-area real estate. It's telling that Barton, an ex-Microsoft executive who got rich through the software giant's spinoff of travel site Expedia, has suddenly become interested in keeping his home address private. Could it have anything to do with his new business of telling everybody what their neighbors' homes are worth?

Barton, who famously founded travel Web site Expedia as a Microsoft property before it split off and sold to IAC, has apparently been telling investors that the company will make $40 million in revenue by the end of the year — even though the best estimates within the company peg the amount at more like $8 million, according to a source. Meanwhile, the company maintains a lavishly appointed office on the 46th floor of the Wells Fargo Center in Seattle's central business district, and has raised a total of around $87 million in three rounds of venture capital funding.

Trulia, which offers similar price estimates for properties, is neck-and-neck with Zillow in terms of visitors according to Compete. However, Trulia has only raised $33 million and is headquartered in a relatively humble office building at the foot of San Francisco's Portrero Hill. Granted, savvy visitors probably check both sites because the numbers provided can often be wildly inaccurate. Sort of like Barton's revenue estimates.
