It is a radioactive, colorless, odorless, tasteless noble gas.WikipediaSymbol: RnAtomic number: 86Electron configuration: [Xe] 4f145d106s26p6Did you know: While other estimates might be higher or lower, there is general agreement that radon exposure is the second leading cause of lung cancer after active smoking and the leading cause among non-smokers. nih.gov..    

The only problems with this property is the previous owner was a smoker and had cats.

I agree with @Mike Dorneman & @Matthew Paul I also do the prescreen telephone interview and only setup a showing when they meet the prescreen criteria of adequate income, no prior evictions, referrals, no smokers and no pets (in my case).

I will never forget when you grilled the guy who said roof replacements are not a concern or his on rental properties.

I did the same as others and also put in lease that on outside of property there are to be no open flames or grills of any type within 25 feet of any structure on the property. 

I painted both of the vacant units because there were smokers before and the walls were yellow.

Very run down, heavy smokers.

Smokers and a kennel of dogs destroys properties faster then a tornado. 

Thank you Taylor.I visited the property yesterday after running the numbers: To make matters worse, one of the unit's former tenants were heavy indoors smokers, trashed some doors and toilets, and there was a electric line that was 10 ft from the ground.The upsides that I see:1] Long-term tenant in the next unit, Section 82] Close to the universityAny limitations to rent increases regarding Section 8 tenants?

After the 3rd smoker came out to walk their pit bull, I said hard pass.
