Does your city have any specific regulations as to the procedures for dealing with delinquent tenant?  

You also want to find out exactly what the procedure is to end the lease or raise the rent if you choose to go that route instead.  

 I would suggest having written qualifications and follows your policy and procedures if you deviate from that and they finally federal lawsuit on you you wish you had in many ways If they do not fit your qualifications that are  written down and apply to every single applicant then you're OK if you deviate from that and bend the rules you could be violating the fair housing or a discrimination law 

If they refuse to pay you will need to follow the procedure as outlined by your state codes.

I'm implementing a new key sorting system, procedures for contacting tenants and contractors, and a new office space.

We have gotten pushback after checkout a time or two (mostly from young guests, -__- ) so we word our checkout procedure as "please complete our quick 3 step checkout procedure to help our housekeeper, Monica, quickly prepare for the next guest."

We  have a procedure in place for changing the make-up of the household. 

Have very clear dispute resolution procedures.  

Is asking a property manager what rent should go for, the standard operating procedure? 

Although I've never had that happen to me, I did receive a medical bill for the first time...THREE years after the procedure.
