I'm hoping that once they clear all their stuff out it won't be too bad. I'm sure a lot of the smell is held in their furniture and other soft things. I don't think they smoked in their the entire 2.5 yrs either. The last time I was in the house before discovering the smoke was about a year ago and I didnt notice anything then.
