Me and my DH currently rent a property from my mother in law she charges us less than market value for the house which we really appreciate. However she has a key to the house and let's herself in as and when she feels like, she has often made comments about mess or clutter she isn't happy with when she turns up unannounced. She will often take it up in herself to clean or reorganise areas and has on more than one occasion decided to paint refloor or decorate without asking. I also know from my doorbell footage that she has let tradesmen in again without asking and at a time that she knows I'm working.
It has got to the point I don't feel comfortable in my own home and am really struggling with anxiety, am I been unreasonable to ask for notice for her coming around and only to do so when necessary? DH thinks I'm over reacting and that as she owns the house she is welcome to come as she wishes and feels she is only trying to help.
