$$$ that term you hear investors say "smells like money" depending how crafty you are and how good your negotiating skills are this could provide an opportunity to really come on top. you just have to determine what your tolerance is and have a plan. 

(I cannot stand cigarette smell) In any case, my landlord tried getting rid of the odor, which was always temporary and basically smelled like a "pretty smell" mixed with the cigarette smell.

People can smell its not he real deal, so are being polite, but not going to invest their money.  

Not heard of any limits there.The only limit on body count I can think of is for S-corp designation (governed by federal tax code). 

There are around two dozen other major industrial operations in the area including the telephone pole factory that smells like burning tar, the Purina pet food factory right across the highway from the elementary school, and the highest concentration of superfund sites and brownfields in the country.

@Bryan Cavellier you can make a rental too nice to the point where you don’t make any money because it doesn’t fit the area and therefore no body will rent it from you.

This area is not much for trees, mountains, or natural bodies of water.

However, I'm not sure selling to you eventually would pass the smell test of an arm's length transaction.

Smoking inside will damage your home and you will be kicking yourself once you are trying to get rid of the smell when they leave.

There's possibly something very wrong, like a dead body in the house.
