If you have a rich imagination, then I don't think I'd worry about it since it's not something you act on. It doesn't seem to interfer at all with your job or other aspects of your life.

On the other hand, if this turns into a whole fantasy existence for you for months on end during which you explore real estate possibilities online, even email agents ... Well, you catch my drift ... Yeah, then I'd call it a problem. So it depends.
