Despite his efforts to portray himself as a down-home, country boy man of the people, Kid Rock did not exactly grow up in a trailer park as he hinted in his 1998 song “Cowboy.” Rock’s childhood home, a five-bedroom 5,660-square-foot mansion on a five-and-a-half acre estate, is up for sale now. The house was built in 1972 when Rock was one year old. Among its many amenities, it boasts a five-car garage, partly finished walkout basement, guest house, three-stall horse barn, tennis court and a pool, all renovated and sitting on a panoramic parcel of land. The house has been put up for $600,000 and is being offered in “as is” condition. It’s located in the Macomb County area of Michigan, a more rural enclave adjacent to the Detroit metropolitan area and a more conservative part of the state.
