They say the future is in discounted stocks, in apartments, in crypto, in agriculture, in marijuana etc.

Also if marijuana is legal I also will not allow it.That is just one example but there are many others which are property specific (who cuts the lawn) etc that you may need to think of.

Or more recently, the legalization of marijuana - we can state our opinions and suggest to people what we feel may or may not be appropriate.

What was peculiar was that everything that was deducted had an accompanying receipt except for the blinds which had a copy of a Home Depot online shopping cart for blinds that hadn't actually been purchased that was printed yesterday which makes it seem like an afterthought.

There is also a page they sign that says they are out in 24 hours if there is any drug activity, and another stating if they want to grow their own medical marijuana (legal here) then they have to get their own liability insurance.Things I added include that the tenant is responsible for replacing light bulbs within their unit, they are responsible for clogged drains and my use drano, replacing a missing smoke detector will be $50, no flushing things other than human waste and toilet paper- no flushable wipes specifically.  

The police smelled marijuana when the tenant opened the door which gave them probable cause to search. 

Include the CCR in your lease and have the tenant sign that if fines are incured due to the tenant behavior, the tenant will be in breach of the lease.99% of the time the tenant is doing one of a few things: parking in a red zone, having loud parties, bringing to many guests to the pool, unsightly belongings visible, unsupervised pets, not leashed, defacate in the common area, unsupervised children (that make noise and break stuff), speeding in the deiveway, bringing food, glass, beer or marijuana (legal in CO but not CA) into the pool area, indecent or illegal activities in the common area.I've seen it all.

@David Hunter It was Marijuana trafficking.

I'm thinking drug dealer/marijuana grower

also: service animals we mentioned a few times by others  i actually would not mind a service animal in any of my apartments i feel there more well trained than people. the emotional support animals certification , i feel i going to abused more than medical marijuana cards in the future ( i live in Michigan its pretty bad here ) as more people are living in apartments and having pets instead of kids .
