Burbank Castle in Burbank, California is one of them, and it is available for the first time for $4,995,000.
Known as the 'Harry Potter House', this four-bedroom, four-and-a-half-bathroom mansion cuts a magical silhouette in the Burbank hills.
Inspired by the homeowner's travels in England, the custom-built Victorian Tudor is on the market for the first time since it was built in 2002.
"This home easily has the most amazing, unobstructed views in the valley," said listing agent Scott Rosenthal.
"It's the ultimate view home, all to be enjoyed with a glass of wine in the infinity-edge hot tub."
The 5,317-square-foot mansion is located approximately 12 miles from downtown Los Angeles.
"From the moment you walk in, you're greeted with travertine floors, 200-year-old maple wood floors, custom-painted murals, stamped copper ceilings, hand-carved beams imported from Mexico, and much more," Rosenthal says.
The master suite features vaulted ceilings, a walk-in closet, an en-suite bathroom with steam shower and soaking tub, and a private wrap-around balcony.
The layout includes a formal dining room with a ceiling mural, an open kitchen, a family room, a library and a lift.
The 0.7 acre lot includes a saltwater pool, an outdoor kitchen and a four-car garage. The driveway is gated.
