If there are winterization stickers on any of the fixtures, what are the dates on the stickers?  

A modern, power-vented, condensing water heater is 20% more efficient than an older draft/convectional flue water heater.The upfront sticker price is normally <10% of the lifetime operating costs ... if you compare an older convectional flue gas water heater (EFT 0.60 - 0.75) to a new sealed-combustion, direct vented, condensing water heater (EFT 0.85 - 0.90), the newer should more than make up for the sticker difference over its life.

What completely made me walk from even considering the Allentown boundaries was hearing the city rental inspectors (yes, there really are "non essential government employees") yammering on about the importance of having a LICENSED plumber change a water heater in your rental.... after you have paid your poundage to the city inspection department for a  PERMIT to change such water heater, and then have it INSPECTED for the purpose of a STICKER on the appliance.... all in the name of safety!

There are still stickers on the toilet and sink in the bathroom. 

He put a sticker over it, but when he moved, the owner peeled the sticker and charged him to repair the hole.

Another alternative is to notice a bumper sticker, boat, car, or something else out front that you are knowledgable about and can strike up a conversation around.

You can purchase these notice stickers thru Great American business supplys etc.

If GA does registration stickers on the license plate like CA does (I've never paid attention to license plates from other states to see if they do it differently), you should be able to see if the sticker indicates that the vehicle is currently registered.Does your rental agreement state anything about only keeping operable/registered vehicles on the premises?
