The Poltergeist house is now listed on Trulia as a witty ad tie-in for the new remake of the movie coming out. Per Adweek:

Click here to see the house listing, which is located on 1295 Brimstone Ave., Willow Point, Illinois.

1295 Brimstone Ave Charming, contemporary two-story single-family home with 3 beds, 2.5 baths, separate office -- and lots of potential! Built in 1982 in the lovely Cuesta Verde housing development, the ideal neighborhood for any growing family. Spacious Living Room with an open layout, perfect for entertaining numerous guests, complete with spectacular bay windows with arched glass panels, and a modern brick fireplace. Inviting French doors lead to an office/family den. 

According to Adweek, “The listing is chockfull of Easter egg hints, cheekily letting the reader in on the house's back story in relation to the movie. ("Housing development is built on a site with a lot of history.") The map even flickers in and out, making it seem like a ghost could jump out from the screen.”

If you want to see the inside, here's the trailer for the upcoming movie.
