After doing the same kind of screening that I do out here in the Bay Area (No Smokers, No Pets, No Felonies, No Evictions) we still had many people that wanted the units.

Even won a smoker! 

4) Are any in household Smokers?

They also will claim they smell smoke from cigarettes. 

I have had tenants tell me I could not discriminate against smokers, had no right to verify employment, no right to look at credit scores, no right to restrict countless things but most often it is pets, no right to do inspections even though it is clearly spelled out in the lease agreement that they signed. 

But you know what -- joke as we may, none of us tossed it.Some even set it out on their desk with what must have been some measure of pride, small as it might have been.So yah, none of us could take it to the store to buy cigarettes, and we couldn't melt it down into a gold nugget that would let us retire, and we all had a good ol' time joking about it, and I doubt any of us worked any harder for the Man over it.

Because she was a smoker, the cobwebs were like yours except they were black and tarry.  

There is also a smoker smell in the home.

I'm currently living in a multifamily house hack so I'm personally dealing with guests almost daily -- I've had a couple issues recently about trash duty (guest refused to take it to the curb), litter and cigarette butts left around the property, laundry room left open and not cleaned... 

I don't do drugs, I don't even smoke cigarettes, no pets...
