BUT, they ignored the advice because of an anomaly.That being said, even the 80 year old chain smoker could have benefited by NOT smoking, despite being healthy.

Since my latest acquisition was 3 miles away from my previous primary residence, I was asked by the selling agent representing Bank of America, and grilled a few times by the underwriter at Wells Fargo who I got the home loan from about making sure I was going to use this as my primary residence, I had to sign affidavits for both banks stating it was going to be my primary residence.

I don't take section 8 and I don't allow smokers or pets.  

I also always listed "absolutely no smokers, not outside smokers, not inside smokers" on my roommate listings, blaming asthma.

Propane stoves will run off the same bottles you use on your gas grill .

I have that as well as a few other common sense rules - like don't throw cigarette butts on the ground, grills/BBQs can't be used inside, etc -- the lease is a bit lengthy, but I feel having some of these stated is required. 

We also stated the requirements {No Criminal or Eviction background, make 2-3x the rent PER person, verifiable job number, minimum of 525 credit score (our area did not harbor people with the optimum credit score), and extra $25-$50 monthly payment for smokers and pet owners (per pet) its waived if pet is a verifiable service animal}.When people call, we repeat info on the property and the requirements list.

We got a limo-van tour of 3 properties, we had snacks and some class time at Phil’s mansion, we got hotel food in a private meeting room, and we got a steak dinner at Perry’s Steakhouse and Grill.

Trying to accommodate both smokers and smoke sensitive tenants is a nightmare, frankly.

As I am not a smoker, I have no idea.
