Tenant Moved Washer and Dryer without my consent

[Kevin Nolan]

Oh boy oh boy - So backstory, I just purchased this 2 unit rental property back in October 2020 and it came with washer/dryer that on the contract stated belonged to one of the tenants(who is section 8 and has been EXTREMELY high maintenance so far and paying $500 under market value). 

I walked down into the basement today to check something in which I saw that brand new washer/dryer machines were installed/moved from one end of the basement to the complete opposite end. Meaning they had to cut through for a new vent on the dryer on the other side of the basement and I did NOT give any consent on this. This tenant has been on month to month since purchasing the rental unit but just recently signed them to an annual lease a few weeks ago. 

Does anyone have any insight on how to handle this? Is this grounds for eviction? Keep in mind this tenant has been very demanding with requests on fixing stuff that had been broken for years and has tried taking advantage of the fact that I have been nice and dealt with her requests so far (which I understand now that I can't be too nice to tenants or else they will take advantage of you). If she wasn't so high maintenance and I was getting more money in rent instead of barely breaking even I wouldn't care as much but this is excessive and I have to do something about it or who knows what she'll try to do/install next.

Please any help here would be greatly appreciated
