We had grilles in between the glass, and had the best glass put in to keep heat gain to a minimum, which also got us a $30/window credit from our energy provider, which further drove the cost down.

I also do not allow any belongs to be left in the halls, porches, or yards ect. with the exception of a grill (this is huge) I have a clause stating these items will be disposed of without notice.

No pets, non-smoker.  

Minor selling points are having more space and privacy, a streaming HDTV, bbq grill, and outdoor recreational areas.

Off the top of my head and keeping in mind that we all have standards that may not be strictly legal would you reject some of these :Neck and facial tattoos, single guys, recently separated women, single mothers, welfare, restaurant workers, nationalities know to cook offensive smelling food, smokers, low income immigrants, bikers, tattoo artists, recreational drug users, prostitutes. others.Or based on human rights laws etc. is everyone welcome as long as they pass basic screening standards. 

The Memphis Area ranks last for personal savings and is where the Chapter 13 bankruptcy was invented.You can legally discriminate against smokers or attorneys for example.

Newspaper ads are inexpensive.Note: develop your rental policy to avoid people wasting your time (3x rent, pets, smokers, application fee, proof of income, credit/criminal background, etc.)

I accept short-term.I don't accept smokers, pets, or evictions, or people on probation.

You can look into a smoke outside only policy, but it is hard to make a leopard change their spots (if they have been smoking inside for years, good luck changing the behavior)...If you want to go no smoking at all,  you could just give notice with month to month or not renew when the lease ends, but the inside smokers can create quite a lot of work on the turnovers so you have all that work now (when closing taps your cash) and an early vacancy plus losing a good payer...Maybe get inside and assess the unit and behavior some and consider if it workable another year or more (who knows they could stay years) or if you need too make a change.

To be fair to your tenants, smokers need a place.
