@Ian Ippolito I was going to post I pitty the fool that post on BP saying they have XXX dollars and does not know what to do with it.

The only information recorded on the deed is that the owned is xxx trust with yyy as trustee.

I think you should pursue the same angle here. i.e. an accounting shows that the actual costs (attorney's fees, mailings, any actual repairs) are $XXX.

Emergency Contacts and Guidelines If something needs to be repaired or replaced:Please contact xxxx, LLC by sending a text message to xxxx at 303-xxx-xxxx.If you do not receive a timely response, please also try 303-xxx-xxxx.Fire, medical, or police emergency:If it is an emergency call 911.Please replace batteries in smoke and carbon monoxide detectors as needed and leave them and the fire extinguisher(s) in place.

Best to call me at xxx-xxx-xxxx' a thousand times over the past 10 years. 

I will need some flexibility in scheduling as we have a move in date of XXX".

Second, your rent will be locked in at the fair market rate of ($XXX) and cannot increase for the next 12 months. 

I'd just send them the required notice and tell them their new rent is $XXX.

We saw similar activities again on XXX date.Then we note how this activity inconveniences other tenants, blocking mailboxes and driveways creating excess traffic or causing noise complaints whatever...Then we list the section of the lease that prohibits conducting business in the apartment and say that these activities are consistent with some retail activity and as such are a violation of the lease noting the paragraph.Then we congratulate the tenants on their entrepreneurial spirit but say that we think the best solution is for them to move and offer to waive penalties and fees and return the security deposit within 24 hours of move out if the apartment is left empty and clean (with clean fixtures and appliances), less any past due balances.

The $100 or 10% is common, but I like the fixed dollars - - it's expensive enough to be painful and to encourage prompt payments.BTW:  TRAIN your tenant by issuing a courtesy notice ONLY ONCE;  "Your rent was late this month and if it is late again, I will apply the late fee of $xxx."
