But I had a smoker unit that I bit everything and it has held up so far.  

Our only hope may be to target the right audience (for long and short term rentals), "Pot Smokers Welcome Here"!! 

There is also one down in Kenosha every second Thursday of the month at 7pm at the Birchwood Grill.

Anything beyond that (cable, wifi, Netflix, outdoor grill, etc) is a bonus to them. 

Later we tried to use the grill, and the propane was empty.

Hire a professional Realtor and really grill them on how they plan on marketing your property and listen to them on pricing.

It is also likely illegal, but I don't think anyone will get charged anytime soon (none that I know of yet) - as prosecutors are too busy putting dope smokers in jail, rather than seeking to ensure our system of money and lending are sound. 

A smoker lived there for years.

For example, Americans in general love to grill at home.

Emerson Zollos,I'm in the same boat with a duplex, where one of the units was occupied seems to be a chain smoker - the walls, ceiling & floor are just completely saturated with cigarette tar/smoke.While I haven't begun rehabbing the 2nd unit, I've been doing my homework on the best way to tackle this project and what seems to be the most effective treatment that I've found so far, short of ripping out the drywall/plaster & lathe, I've been reading that using a TSP solution with warm water very effective in removing the "gunk" so to speak - once the walls have been thoroughly cleaned with TSP, use an oil-based primer (Killz) to seal the walls and then apply a few coats of paint.
