Singer and actor Mac Davis has paid $4,900,000 to purchase a 4,098-square-foot house in Los Angeles’ Brentwood area.  In a Big Time Listings exclusive, we can report on Davis’ purchase of the house at 346 N. Tigertail Road in Brentwood. Records show that Davis’ 1991 Mac Davis Trust purchased the house back on May 7, with the deal being recorded on May 28. However, the $4,900,000 purchase price just cleared public records in the last few days, which was why we waited to run the item until now. The seller was former ABC president Alex Wallau. Built in 1938, Davis’ new house does not appear to have been on the market. The three-bedroom house has four baths and sits on a 0.44-acre (19,166-square-foot) parcel. Davis’ new house literally is immediately to the west of the 5,423-square-foot house at 12180 Greenock Lane in Brentwood, which actor Robert Downey, Jr. was believed ( to have been renting until recently (and which we ourselves actually visited back in late June). We’re not 100 percent certain, but we’re pretty sure that Davis also has sold his longtime home on a 1.02-acre parcel at 759 Nimes Road in L.A.’s Bel-Air area. Records show that on May 14, a company called 805 Nimes Place LLC purchased Davis’ four-bedroom, 4,364-square-foot house at 759 Nimes for an undisclosed price. (We can’t say with certainty that Davis isn’t affiliated with the 805 Nimes Place LLC company, but we would tend to doubt it.) For what it’s worth, Davis’ longtime house at 759 Nimes Road, which was built in 1926, wasn’t on the market either. Davis also has owned properties in Georgia and in Lubbock, Texas, according to public records. One final note: Tigertail Road in Brentwood is a very celebrity-friendly neighborhood for Mac! Late-night talker Conan O’Brien (using the name “C. Christopher O’Brien) recently purchased the house at 555 N. Tigertail Road after it had been on the market for $10,495,000, while Jennifer Garner and Ben Affleck live in the 3,843-square-foot house at 300 N. Tigertail Road, which she purchased for $5,500,000 in mid-2004 through her Gee Family Trust.
