As part of a remediation, all structures on the property must be tested, and it turns out the "nice little old lady" in the second house whose been there for six years is either a meth user also, or has family that stays there who is - lots of pot paraphanalia seen during meth testing. 

I am not necessarily anti-pot, but as a landlord this would be troubling for me and I would shut it down ASAP..... 

You should buy the property and demand that the church moves so someone can open up a pot shop that also sells alcohol and guns.  

Talk about lacking context to stir the pot!

Add bench strength, get a plan, and buy a magazine subscription.

It's always broke-as-hell wannabes without a pot to piss in, barely anything to piss with, supposedly talking about zero-down-investing but really talking about zero-money-investing.

Again, I don't know if a California judge would agree with you.I'm personally not going to use pot but when it becomes legal in my state, my only concern will be to restrict smoking in the units and I will strictly enforce that.

They have to buy pots when they get here. good luck.

This could include checking on pipes to make sure they haven't frozen in sub-zero temps, walking the property to make sure the cleaner is doing their job correctly, running a package over in-between guests, or running an item over to a guest that may have ended up not working after their arrival...like a coffee pot.

I had long suspected that they smoked pot in their unit (can't hide that smell) but didn't have any concrete proof.
