I served a 30 day notice to unit due to on-going obnoxious noise which was disturbing others.

The only time we do the application first is if we are renting a unit still occupied and don't want to disturb the tenant with a lot of showings. 

If you don't disturb me, I'll leave in 4 months and leave the place unscathed."

His advice, however, was to attempt to evict her on the clause in my lease where she has disturbed the "quiet enjoyment" of the other tenants. 

The purpose of this clause is to protect the staff and other residents.I called in a domestic disturbance last year when a couple got into a loud argument in the parking lot (one asked me to call the police and the other said there was no need to do so -- I let the experts sort it out).

Take care not to disturb it. 

If you have the stomach for it, it's a very rewarding business but sometimes it can be scary, disturbing, challenging & sometimes down right disgusting.ENJOY!

Some Vendors may cite tenant disturbance as a reason for curtailing inspection, but you can usually structure an inspection to minimize inconvenience to any one tenant.   

Or maybe they poured concrete down the drainOr maybe released bedbugs and termites into the house Or maybe put dead fish behind the drywall and patched the holes A dirty tub and a few hundred pounds of metal And a few damaged pipe IMO that is not even close to a disturbing dream tenant let alone a nightmare tenant   Lol

Yes, the involvement of your daughter is disturbing and totally not OK, I would tell the Mother (owner) that this behavior is unacceptable and if she is not sympathetic then don't worry about burning that bridge, it wasn't worth crossing.
