No smoking in the house, maybe not even outside, no loud music (I added no Rap or Metal), minimal phones...You have to be the leader and make them respect you.

@Ilya Schwartz One of the best things you can do is reach out to a local music rehearsal space and try to get them to go there.

The guy in the garage unit plays music and smokes weed so some people like to hang out there.I personally like that there isn't a hangout spot. 

There is also royalty-based financing, for example for oil & gas or music royalties.

You have taste in music... 

We have a required air installation noise zone disclosure, but no disclosure requirement for annoying noise like nearby bars with music, shopping centers, kennels -- it's up to buyer to do their due diligence.

A friend who owns several rentals advised me to start listening to BP podcasts and I can say it quickly took over listening to music on my commute. 

With duplexes especially, the market is composed of buyers with many different motivations.

We have a lot of live music.

The Coronavirus has mutated to be less lethal and is going away all the media hype is fake numbers composed of people who died WITH not from Coronavirus and multiple underlying illness. if you believe the test.
