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.

Our lease states that the pet is approved as long as there is no evidence of dangerous behavior or excessive barking. 

Assuming it is a showing, not entry to take pictures or anything of the sort (unless specified in the lease of course).Not allowing entry is a violation of the Act, and you can serve the tenants with an N5 (Notice to End Tenancy for Substantial Interference with Landlord's rights).You have to give them a 20 day notice period, but they have 7 days to "correct" their behavior, and on the 8th day you can file at the LTB.

Expulsions for bad behavior were rare.For example, the school had the policy of students on financial aid were deemed unable to afford a car.

:Isn't it up to the owner to be able to decide that he doesn't want it as a behavior in his property ?

If the tenant has a respectable history of tenancy with you and you’re willing to consider allowing the pet, I like the idea of a prepaid pet cleaning fee of $250 and additional $250 refundable  (motivation for the tenant to manage their pet’s behavior) deposit.However, none of this matters if you can’t be comfortable with pets in the home.
