My wife and I stand to inherit a 1970s era mobile home, and given the economy and where we live (Southern California), it is an option we have to consider.

The difficulty with the home is that it has been inhabited for thirty years by an extremely, extremely heavy smoker, and the odors are so bad that we have never been let inside the house. Is there a realistic way of getting these odors out of the house -- we often see the trucks of companies specializing in "disaster recovery" -- or will we have to gut the place and completely remodel its interior?

If the latter, are there any resources you would recommend on the problems specific to remodeling mobile homes?
