Tenant problems, looking for advice

[Justin Butterfield]

So I'm a new investor located in Michigan and I purchased my first 4plex about two months ago and one of my four tenants has been a pain on every level and I would like to hear what you guys think I should or shouldn't do in these situations. So the tenant is claiming in harassing her because I was doing some maintenance in the basement of the property and had to hamer two nails. So she was basically upset over a couple seconds of hammering Wich to me would only be worth complaining about if it was alot more than just that. The tenant also says that I'm harassing her be walking in front of her window. To get to the the last two units on the property I have to walk around the building and she is not understanding one bit despite me telling her that we were repairing gutters on the back of the property. I would agree with her if it was a daily issue but it has only been like 10 times in the two months I had to walk to the back of the house for maintenance of some sort. I know I must give 24 hour notice I'm my state for entering the tenants apartment but she seems to think she owns the grass in front of her unit and that's part of the reason she is complaining. She also thinks that anytime I'm on the property I need to give notice to her. I read the laws and I believe that being it's a multifamily and not a single family home then I don't have to give notice to any tenants for just arriving and doing repairs on the outside of the property. I am trying to work with this tenant but she is being very unreasonable and keeps talking about getting a lawyer and such. She is currently on a month to month lease and I'm debating giving her a 30 day notice to get out because of all the unnecessary stress. I'm also thinking about sending her a email saying that if she threatens to sue me again I will have her evicted but I wasn't sure if that is the best way to do that. I feel like I'm just doing my job and doing things correctly, if you guys think I'm doing something incorrectly or breaking the law in any way or have any ideas on what I should do about all of this and who is correct in these situations I'm dealing I would love to hear all your opinions. Thanks in advance
