Material quality sometimes improves (i.e. drywall vs. lath and plaster) or sometimes gets worse (i.e. particle board vs. solid oak trim). 

We live in North Edmond and I have looked at several homes around Waterloo and Charter Oak mainly for rentals but thought it was to far out.

Write to the offending tenant and say a nearby property owner you know contacted you that the police were going to one of your units and tell them if it happens again, they will be asked to vacate as this is a material breach of the rental agreement.First, they won't likely know what their lease really says on this subject, so even if it's a bluff, it should still work. 

However, if the landlord finds it necessary to take the matter to court, you will be happy to abide by the judge's decision.Unless you knew about this fee, it's probably a bluff to try to get you to pay it.  

My neighbors property sits behind and above me on a bluff, while my house is below.

Nice bluff, is my opinion.Because when they accepted money from you, they formed a binding contract.  

He's hoping to bluff you into a deal.
