This is true. I was searching for so long (had the luxury of living with someone) so I was able to tske time. Looked at an apartment that had the tenant still in it. So much I did not see! I felt very uncomfortable being there while someone else's stuff was there so I just breezed thru. Lots I overlooked. Like there only being 1 window and it's in the bedroom. One radiator also in the bedroom. It's not worth it to look at an occupied apartment. I'll never do that again.
