Bank keeps trying to change my locks and cut my grass!

[Matthew B.]

I'm sure some of you have experienced this issue before. It's very irritating and I thought I'd post about it.

I'm working on a flip, which you can see HERE. The property was purchased at a foreclosure auction at the courthouse. 

Several weeks ago, I found a notice on the front door saying that the property had been determined to be vacant and the locks were scheduled to be changed. I called the number on the notice, which turned out to be Wells Fargo. They told me they would update their system and their subcontractors would not be back.

Today, I drove by the property and noticed the grass had been cut. It was quite a hack job. They broke several sprinkler heads with the mower and cut the new sod so short that I'm praying it comes back. 

I called Wells Fargo again, and they told me there was nothing they could do and that I needed to talk with the attorney who handled the foreclosure for them. I called the attorney and they took a message and told me they'd get back to me tomorrow.

My parents have dealt with this before on one of their flips. The bank's goons actually drilled out the brand new locks my parents had installed and changed them. My parents responded by posting a large sign explaining that the bank did not own the property any longer and detailing the manner in which trespassers would be shot.

I plan on posting a nasty sign, but what else should I do short of tying a pitbull out front?
