Wow I am hearing so many great ideas. Initially I was thinking there was no way that the house with the police barricade and end is near signs could be Ray's. However Alphagaia and a few others have made some strong cases that have got me thinking that it could be Ray's house. I was thinking where ever there is Ghostbusters Equipment there has to be a containment somewhere. So what if that house is Rays and all the stuff in front is just a huge scare tactic to keep people away from the dangerous equipment? Maybe this is where Ray and Egon moved the storage facility in order to minimize damage in case there was ever another breach. If that is the case it is bad luck to have a potential containment breach in a town that just may have been built by the Gozer Cult. Man oh man who knows where this is going. I am really loving how much potential screentime the Wrecked Ecto 1 is getting. I am getting the feeling that it is going to be in rough shape through a large portion of the movie and I am really digging it.Being a movie about Ghosts it wouldn't surprise me if that house itself is haunted. Even possibly having been built by Shandor himself. Maybe the caretaker is some religious nut that kicks the bucket Carrie inherits the place.From what we have seen, it makes narrative sense to me the house is owned by Ray and holds an ecto container, which is why he earns people to stay away, plus the ecto-1.
The kids take a look on a dare, accidentally release a ghost and decide to try and capture it to hide their mistake, which escalates in the chase.
Could be totally wrong ofcourse, as it feels like the easy way out, and it might be a haunted house.
I know that this may seem silly to even mention, but if you look at the Ecto 1 as a character, so far it is the only member of the original crew to be working along side the new crew. I am still thinking the kids driving the Old Ecto 1 is a small taste of the old and new Guard comeradery we will be seeing from this movie.
