I think all smokers eventually smoke inside even if, "it's only this once."  

She is a heavy smoker and the nicotine is dripping off the blinds.

When I was in college the neighbor guys got the idea to take the grill into the living room to cook their burgers.

Personally, zero smokers for my properties.

We also don't rent to tenants with pets, smokers or folks who have been previously evicted (which of course also reduces tenant pool, but SOOOOOO worth it!).  

It's probably like  the habitual chain smoker of 80 years is more healthy than the guy next to him who just smoked filter cigarettes for just a few years, and died from lung cancer.Do good, every time you can. 

If they don't would evict themI try not to rent to smokers.

It all boils down to how much the smoker is costing you in lost revenue. 

I'm a bit late to this, but I saw an old tennis court made into a cool cook-out area with just some picnic tables and built in charcoal grills like you see in parks.seems like you have too many courts to just do that, but maybe that plus woodchips and playground equipment would work.

DTI ratio must be 33% or higher, minimum credit score of 720, background check, no pets, non smokers, must sign No drugs on the property document (Federal standard so marijuana is out even if legal at the state level).While I don't specifically look for blue or white collar tenants, I've only ever had white collar tenants.
