An inn room is fine, because when you log back in, the room is the same.

But a house or apartment could undergo various changes. What if someone puts a furniture piece right underneath where you are standing? Is the game going to acknowledge you being there?

I mean look what happened to when apartments were introduced. People who logged out where the "gate" was spawned out of bounds
This is exactly the reason - the development team stated this a while ago when asked the same thing the OP is asking:

A: Komoto: I understand that since implementation we've been receiving a lot of feedback about this, but this is an issue that is actually quite deep and we are not able to address it right away at the moment. Inns, similar to instanced dungeons, have been made so they are set to standby where no resources are consumed when players are not present. For houses as well the programmers were able to work on it so they do not consume resources either when players are not present, but as a result of this, when logging back into the game the room resources do not exist, so there is a difficult issue about how to make it so you can log back in to your rooms.
So sadly I don't see this being changed any time soon. It's just one of those things you have to live with I'm afraid.
