So our newest feature, “Which celebrity’s house is this?”, has drawn a fair number of comments, including from readers yesterday who confirmed for us that the house we profiled yesterday at 914 Chantilly Road in Los Angeles’ Bel-Air neighborhood is indeed actor Patrick Dempsey’s. Other readers confirmed for us that actor Brendan Fraser had indeed owned the house at 9400 Readcrest Drive in Beverly Hills, Calif. until selling it in March.

Today’s house, at 9274 Swallow Drive in Los Angeles’ Hollywood Hills, sold in October 2006 by a married couple for $4,200,000 to something called the Badger Memorial Trust, according to public records. We haven’t yet been able to identify who the buyer is, but it has all the marks of a celebrity—it’s in the celebrity-intensive “Bird Streets” area of the Hollywood Hills, it has a lawyer’s name on the deed, the price is right in celebrities’ wheelhouse, and the buyer’s mailing address is 9100 Wilshire Boulevard Unit 1000W in Beverly Hills (which as we mentioned recently is the address of Grant, Tani, Barash & Altman, which manages many celebrities’ business affairs.

Unfortunately, we have few details on the house at 9274 Swallow, including no photos and no listing information. Built in 1961, the three-bedroom house measures 3,138 square feet, and has four baths and a pool, all on a 0.4-acre parcel, according to public records. The house is just a few backyards over from one of entertainment mogul Byron Allen’s houses, which is at 9329 Nightingale Drive and which he purchased in early 2004 for an undisclosed amount. We wrote about that house—and about the nearby house at 9262 Nightingale that he’s trying to sell and that he still has on the market for $6,995,000, back on March 24.

So, dear readers, we ask you all: whose house is 9274 Swallow Drive?
