When I get an automated response from Zillow, I send an email giving rental requirements such as minimum income, no pets, non smoker, background checks that will be done, etc.

I then have a simple set of questions # people, # and type of pets, # cars, are you a smoker.

Non-smokers, no pets, income 3 times the rent, and clean background.

I also don't allow smokers, do you smoke?

I really don't want smokers.

I grilled him over and over and he said it could be due to the lint clogging up the heating elements.

Landlords may not want a pot smoker, but it's going to be tough to discriminate in the not too distant future.  

Scenarios of subletting, huge amounts of family members moving in, unlisted pets, AirBNB deals under my nose, multiple calls for trivial issues, smokers, hoarders, etc.

Their questions are:1" In regards to prohibited flammable materials, propane grill is ok ?

Not to go too far afield from the original question but this town is different from any other towns with trains because we are  our own little slice or paradise...when you throw your line in the ocean you pull out a plump tasty fish and when you scatter some seeds you grow our own special datil peppers to make a tasty hot datil sauce to brush on your tasty fish...and then throw some oysters and clams on the beach fire grill...we have oceans where you can surf and skim board and Intracoastal where you can Kayak and windsurf  and marshes where you can see pretty pink spoonbills and historic streets and buildings where you can dress like a pirate and drink rum and go argggg....when you can live here NO ONE I repeat NO ONE wants to live by the tracks...so to the original poster I say I would NOT buy anything on the railroad tracks !
