At $18.75 million, this huge Lincoln Park estate has become Chicago's most expensive single family home, and Curbed has the listing photos. The home, which will hit the MLS next month, was quietly listed for sale this week, and as of now has been made available only to "qualified and seriously interested" buyers. Details about the mansion are still sparse, but what we do know is that the huge home comes with an indoor pool, library, a large courtyard with multiple gardens and a home theater that puts all other homes theaters to shame. The estate also includes a two bedroom guest house. According to Crain's, the estate which sits on four city lots at 1955 N. Burling Street is currently owned by Tim Mullen, an independent investor and big time Democratic campaign contributor. The sprawling estate has dethroned Ann Lurie's monster manse as the city's most expensive, but will it sell before it hits the MLS next month, or will it languish on the market for months without any bites? We'll have to wait and see.
