On the rate occasion when we have a tenant who wants to pay in advance we send them to the bank to deposit their funds {in a trust account} and set-up and automatic payment of rent each month.

I have had the rare occasion where HUD has recinded an "acceptance" but it involved vandalism to the property. 

This way you can show that at least they knew and approved of your policy on two different signing occasions prior to moving in.

They have a filter than needs to be cleaned on occasion and if not cleaned can result in a higher expense to clean the interior AC unit. 

They have always been worth my effort and although on occasion I have been redressed by adjudicators and judges as well as being assessed some rent rebates it has always worked out to my advantage.

On occasion, I will make an exception and charge accordingly.

Even with the change to modern heating systems, the tradition of keeping windows and doors open may persist.Religious belief systems may also call for the opening of a door or window on occasion.

We've had to personally deal with sewage backup issues on 2 occasions, and it is not a pleasant experience, minor or major. 

I have had to tell tenants on occasion that renting a house is not like being in a hotel where there come fix each and everything immediately. 

I emailed and texted her on many occasions and asked her to stop.
