I wouldnt really consider myself an "IDOC hunter" but I do run around looking at house signs from time to time, and if I stumble on a worn house, I mark it and see if I get lucky.
So far I havent gotten too lucky. Ive been the only person there at 2 different idocs in the last couple weeks, and there was only junk in the house.
But anyway....
My question is about these houses I run across that say "Owned by: OSI"
They seem to deteriorate at the normal rate, until the time where it should go from greatly worn to IDOC.. and then poof!! it refreshes.
What is the deal with these houses? Do they ever fall?

Yes, when they are done doing whatever it is they are investigating. Then the house will fall and all articles should actually go POOF from my understanding Nothing to gather.
I might be wrong, haven't had any java yet!

There are also houses all over that are perma-OSI owned, never fall, never decay and just take up space. I notice this alot with the little 1 room small houses(not sure of the style name) But there are places where they are stacked next to eachother and just get in the way.
