Families couldn't move out fast enough from the infamous "murder house" in the first season of the popular FX series "American Horror Story." But now families may be willing to pay millions of dollars just to move in.

The 12,000-square-foot home that served as the exterior model for "American Horror Story" is set to be sold for a cool $12 million, and a Syfy reality show will be on hand to track its sale.

Joe Maddalena, founder of Profiles in History and host of the Syfy series "Hollywood Treasure," is set to help sell the murder house through an international marketing campaign in the May 29 episode of the series.

The house, according to the series, was built by a deranged Hollywood doctor to the stars (who most likely was also the Black Dahlia murderer), and would end up being the scene of many grisly murders. The key to the house, however, was that if you died on the property, you would live on as a ghost that could live and function like a normal person.

In reality, however, construction of the house began in 1904 and was completed in 1908, according to a release. It was designed by Alfred Rosenheim (the designer of Clume's Broadway Theater among other structures), and is a designated historical monument. The Catholic Church added a chapel addition in 1954.

It sits on three-quarters of an acre of land, and is located at 1120 Westchester Place in Los Angeles.

Interesting enough, before the house was cast in "American Horror Story," it was on the market for $4.5 million. Amazing what a little publicity on a well-known series can do for your market value. According to a real estate listing from before the airing of the series, "murder house" is a six-bedroom house in the city's Country Club Park. The main house is three stories tall, and the detached ballroom was once the chapel, and at the time of the listing, was used "as a recording studio."

The house, according to the listing is "decked out in Tiffany, with stained glass windows, light fixtures, leaded-glass display cases." It also has "museum-quality" Tiffany glass doors, a formal dining room, six Batchelder tile fireplaces, and a solarium.

The house itself has a bit of a history similar to what the show portrays, but not in the murder sense. Instead, the house has been on and off the market quite continuously since 1999, going as high as $7.5 million as a listing price in January 2009 before being offered again in late 2010 at $4.5 million.

Maddalena is a popular purveyor of television and movie artifacts, not only helping owners determine if what they have is authentic or not, but also providing expert advice on what such items would sell for on the current open market.

"Hollywood Treasure" airs Tuesdays at 10 p.m. ET on Syfy.

The second season of "American Horror Story" will come this fall on FX, but will have a different location and new characters, creating an anthology feel for the series. Many of the actors from Season 1 will return, but in totally new roles.
