"Why would I reward such behavior?"

This will limit the number and regulate behavior.  

A hoarder won't change behavior just because they got a fruit basket when they moved in.

If that doesn’t work, start to get tough and demand this behavior stop. remember this is our business and our money we are losing daily by their activities, they are taking from your business the more damage they do.

Trying to stop that behavior is impossible.

Just add on a fee to booking.com to reflect this if you want. there is little evidence that pre-screening results in better behavior from my research.

Within two months, my wife and I received vulgar text messages from our former neighbor complaining about the tenants and noise.While fixing some items at the unit, the other neighbors on the block noted how great our tenants were and how appalling our former neighbor's behavior had been.We received word yesterday that our tenants will not be renewing their lease and are seeking to break it early - noting that the neighbor is simply intolerable.

I'm preparing a letter regarding a lease violation (two unauthorized dogs) and a review of her unacceptable behavior.

Then, when you finally collect the funds for the owner, you hit him with a $150 fee which is probably equal to a month of management fees on top of the management fees you'll already collect for whatever rent income was paid by ERAP.This is the kind of behavior that gives our profession a bad name.

Past behavior is the best predictor of future behavior.
