Nowadays tipping is starting to creep in as an expected behaviour over there, despite the good wages...but guess what?

That interpersonal aspect I am sure you have seen thousands of times is what I like probably the most.

I entered the real estate world when I was 18 by getting my MLO license and I learned that you can read all the books in the world but it means little if you don't have the connections and interpersonal skills necessary to succeed in the industry.

Landlords are responsible for the behaviour of all tenants.

Junky tenants are more responsible for pest infestation, so it's good to clean up your house on a quarterly basis and change pest control frequency as per tenants behaviour.

The financial industry knows full well that past practice is a solid indication of future behaviour.

I know this is a bit late, but based on your "friends" behaviour, it sure looks like he is in financial trouble.

All your other issues , having to deal with irrational tenant behaviour, is common.

I concur with others, the behaviour is not odd.
