I can guarantee you that motion picture hadn't started yet. I believe that around 1910 the first motion stop pictures were shot. I'm not sure about that though, but definitely early 1900's. Photography was around a little longer, but not by that much.<br/><br/>Personally I think it would make sense that others owned the house and modernized it, but then disappeared for various reasons, and that the house didn't find new occupants for the past 20 years or so. If the previous owners owned it in the 1990's than LAN cables would be missing, but central heating, telephone lines, tv lines and electricity would be there. The house also wouldn't be in such a terrible condition that it's nearly rotting away due to lack of maintenance. Sure, a lot of work would need to be done, but it'd be managable. Doing it like this would also allow you to use any ghost you want to add.<br/><br/>Does this make sense?
