We just turned an apartment previously occupied by a heavy smoker. 

You have no further obligation to these people, if they press tell them you do not rent to smokers and hang up. 

Example from my last real AD.HOUSE FOR RENT3BR2BAmore infomore infoI WILL ONLY RESPOND IF YOU LEAVE A REAL PHONE NUMBER$50.00 non-refundable application feeTypical Qualifications: 600+ Credit Score| No judgements | No evictions| No criminal background | No smokers| No delinquencies |2 pay stubs| whateverElseIRequire ------------------2) I do this to help reduce the amount of callers that will not qualify.3) If you decide to screen over the phone I ask.

I also have smokers (non-smoking building) and one with a dog (service dog for a bad knee) that is not cleaning up after it.

-Smokers welcome, but any stains on paint that need painted over come out of the security deposit.Tenant screening requirements-Landlord references required-At least 1800/month in verifiable household income.-90 days work history required.

Have they said when the smoke or where the smoke is more noticeable, In a complex I managed a patio smokers fumes went right up and in the above units door.. it's hard to control, best to eliminate if possible.. any cigarette use in common areas is lease infraction, so no halls, laundry rooms, ect for that. 

Quick question, I know most property owners dont want smokers in thier units but has anybody actually marketed TO smokers?

Several have hard core smokers and pets. 

One of the units is in decent condition and the tenant seems fine, but the other two units are rough and I would be inheriting some chain smokers who live there now.

This binds all adults to the terms of the lease.Smoking: I want to know if they are smokers.
