Glitzy 1990s Portland mansion that sits on 40-acre estate becomes city's most expensive home after being listed by its Ritz-Carlton developer owner for $15 million

The most expensive mansion in Portland has been listed privately for $15 million. 

Walter Bowen, the developer for downtown Portland's new Ritz Carlton hotel and residence tower, has listed his 40-acre estate near Forest Park for sale.

Bowen's English Tudor Revival mansion, referred to as English Oaks Estate, is the most expensive residential property for sale in Portland. The 16,828-square-foot home is located on a 120-acre development shared by three owners.

The property that comes in second in terms of its price is the Tahoma penthouse in the Ritz-Carlton with an asking price of $8,999,000.

The developer bought the Tudor Revival mansion in 1993. The four-level brick house comes with Ipe wood floors, marble-topped fireplaces, seven bedrooms, nine bathrooms, and three powder rooms. Additional features includes a turret, a slate roof, a home theatre, a guest apartment, and a fly-fishing workshop.
