Trolls are miserable people, they hate life and so they are their own punishment lol and the asperger kids that come on here and heckle people like you will never succeed in business because nobody will ever want to work with them if they communicate like that.  

Never simply throw up your hands and quit, criminals need to be punished.

We're concerned that punishments will cause tenants to move and that incentives will be unsuccessful.

Or got an unlawful detainer?

I have advised her to notify the landlord of her intent to move, and to threaten legal action over the unlawful entry if her landlord insists on her paying rent through next year, keeping her security deposit or reporting her to the credit agencies. 

The key is establishing and maintaining open and honest communication, being polite and respectful, having a strong rental agreement in place and having the moxie to enforce it in a professional manner.From our rental criteria:RESIDENCE/RENTAL HISTORY1.We will examine the most recent five years of residence history.2.Home ownership will be verified through the tax assessors office and/or credit report.3.Rental history will be verified through the property owner and/or rental agent. 4.Rental history reflecting any unpaid past due rent, damages or fees will result in denial.5.Rental history showing excessive property damage, excessive noise, or unruly behavior will result in denial.6.Three or more notices for failure to pay rent and/or to comply with the terms of the rental agreement, within a 12 month period, will result in denial.7.A person with an eviction or unlawful detainer on their record may be approved if full restitution has been made.

Does not matter what the municipality says if you have not been consistently collecting the fee tenants are no longer obligated to pay since the landlord makes the decision to collect not the municipality.Municipality is only a suggested guide line not mandatory.State legislation does not cover late fees.You would be farther ahead to train your tenants than attempting to punish them.

.* If you do not follow the terms of the “Notice to Pay Rent or Quit” we may then begin eviction proceedings against you and you will be charged with the crime of “Unlawful Detainer” if a judge upholds our claim.The amount of rent now due, as of today’s date _________________, is as follows:Current Month Late Fee_______________Current Month Rent_______________TOTAL DUE_______________Time is of the essence.If you have not already posted your rent via the mail, please call us immediately to make arrangements for us to collect the rent in person.Thank you for your prompt attention to this matter!

I purpose of a fee or monthly charge is a punishment to discourage tenants from having pets and for the landlord to benefit when they do.
