Does anyone else think this is wrong?

My mom is 52, lives alone and has rented a single wide trailer for the last 5 years. The trailer is 2 bedrooms, 1 bath and has a decent yard. She pays $475 a month and where we live that’s pretty expensive especially for the size. I lived with her the first 3 years but my husband and I rent somewhere else now. Her landlords have a laundry list of rules for her. She can’t hang anything on the walls, can’t smoke in the house, can’t have any pets and she has to run even buying new furniture by them. I know the contract has a lot more rules I just can’t remember them right now. I’m currently 31 weeks pregnant and my husband works 3rd shift so a lot of weekends we stay with her mainly to keep her company and also she lives 5 minutes from the hospital where we live about 30. Here lately the landlord has been getting extremely hostile and rude about us staying with her or coming to visit for a few hours even when she needs help with things. Today he came by and told her that they are going $50 up on the rent, if my husband and I do move in (we have no plans to because we have our own house) it will be $100 a person a month and that he believes she’s smoking in the house because her tower fan looks like an air filtering system. My mom is devastated. These people have been so good to her the last 5 years and she’s been the perfect tenet and now it’s suddenly changed. My mom smokes but it’s always outside like they wanted and it just smells like smoke on her clothes. I told my mom if they expected us to move in it would end up being $825 a month for a tiny trailer when my husband and I pay $450 for a 3 bedroom, 2 bathroom trailer and are allowed to do pretty much whatever. He keeps badgering my mom about believing we live here when we’re not even there most of the time and we clearly have a house big enough for my husband, my son and I. Why would we trade that to move into a tiny trailer in secret? I told my mom she just needs to find somewhere else because I believe they’re doing her dirty. We may be in the wrong but in the area we live in those demands are unheard of and we all feel like my mom would be better off living somewhere else. Side note: she can afford to buy a house with no problem but after my parents divorce she feels it’s better to rent so she’s not tied down to anything.
