A landlord should never threaten if they can't/won't follow thru.  

I have been told if the heat is life threatening then it is an emergency to fix the ac. 

I told him no i can't pay for it. but he is insisting that i do it and is threatening to move. what's the best way of dealing with it?

the story starts in January of 2016, when i added a tenant to my one family house. 10 days later she decided to move her stuff in. she rented a one bedroom in my house and was bringing in her belonging that could fill a fill 1 bedroom apt. when she didn't have enough place to put her stuff she began to leave everything in the living room. when i confronted her about it, she began to act threatening and irrational. i thought "hey she is stressed. let her cool down. the following day i tried to talk to her and she really lost her mind. i told her "it was not going to work out and she had till the end of the month to find somewhere else to leave.

It's a full time job just threatening to leave these big companies because they keep trying to raise rates.   

You are definitely in a bad position if you no longer own the property and now the new owner has a deadbeat tenant in there.Sounds like the PM dropped the ball and I would threaten licensing action on them if it were me.

When my daughter fired them, and threatened to sue so they forfeited the clause in the lease saying she had to pay them the fee you're talking about - they offered my daughter's tenant another property that they managed.So, they were expecting to collect full management from my daughter for firing them, then put my daughter's tenant into another property, where they probably got paid to evict the last tenant that they themselves put into place.And the tenant they found for my daughter were problem tenants, and they knew it, and they were ready to put them into another owner's rental, where they planned to let this complaining tenant continue to make them money on all of the maintenance calls this tenant was likely to drum up.So, my answer to your question - sure it's standard. 

He only responds to me if I threaten to take expenses off of the rent.

Running wild/threatening others.

Therefore he is not going to threaten to sue them for his loss.
