Tenant from hell? Have I spoiled them? What can I do?

[Dustin Long]

I have a tenant complains about EVERYTHING and even undoes some of the repairs I make. He's told me he's reported me and that I'm a slum lord. I have over $1,100 in receipts since January (I even bought shrink wrap window treatments to help him save heat, and his response to that was "When are you going to install them? So i begrudgingly did). I sent my repair man over today with a brand new window to put in and he refused to let him in and only will deal with me. I'm out of town until Monday and can't personally attend to the matter, but he refuses to deal with anyone but me. I have 2 other houses within about 100 yards and they're both great tenants. What can I do if he refuses to let anyone into the house to do repairs but me? He also takes off work when he demands me to come over and then tries to make me feel bad because of it. I'm in upstate NY and very frustrated...
