I'm going to start house hunting for my first home. I would like to take pictures of each home so I can review them later. Is that normal to do, or do I have to ask permission at every showing? To Amy: no, they don't - that's the problem. Most homes online (for my city anyway) have pics of the outside, but not the insides. I suppose it would be rude if the current owner still lived there, but most of these places are vacant.
