am i going to get kicked out of my house? (trauma)

So, I live in a house my dad’s parents bought in 1930s. My dad has lived here since he was 22 and he is now 59 years old. He has never relocated nor has he ever paid rent. He has a lot of mental health disorders and because of that his parents granted him this house debt free. I live here as well with him, I have since I was a child and now i’m 25. All of a sudden his mother is asking for us to move out so she could start renting this house 3-4k a month. Mind you, this home has never had deep renovation since they bought it in the 30s. Only thing that has changed is the kitchen and some plumbing, everything else is the same, the windows, doors, wood, everything. It is in BAD shape, it has termites and mold but other than that my dad could never pay to remodel it and he never cared too. That said his ex wife, my mom, lives here with us. She was an alcoholic and has cussed at my dads parents when they were fighting (she had periods of mania and have had suicidal/manic episodes, she was taking drugs and in a really bad mental state for some years but my dads parents never saw that). HOWEVER, when my mom left my dad, my dad lied and completely shoved my mom under the bus, he lied saying he was paying alimony, that he was struggling so bad with money due to my mom leaving (he was purposely missing weeks of work on his own accord) and was saying she chose to be a addict etc etc to my grandparents so they could help him out when he was missing weeks of work. Anyway as you could imagine my dad was very unstable, not an alcoholic but abused drugs because of his mental health disorders. He went on medication in 2023 and it has stabilized him a bit. (He has severe autism, ADHD, and bipolar tendencies) But because of how he spoke about my mom and how they have NO idea my dad abused my mom so severely, my grandparents hate my mom.

My mom is now sober, shes been sober since 2023 and so NOW my parents are normal and coherent. Anyway point is the house is a mess, and like I said, my dad’s mom hates that my mom lives here. Long story short, she doesn’t know that my dad emotionally and verbally abused my mom their entire marriage when he wasn’t on meds. With that abuse she became self loathing and an alcoholic and etc etc you get the gist. I begged my dad for my mom to live here because she was going to be homeless (I was 17 and at this point i was being verbally abused by both of them on a regular basis but couldn’t have my mom be homeless) SO. we all live here now.

SO what triggered this from my dad’s parents? Well my sister and I just leased a 2025 car and that seemed to trigger my dad’s mom. Long story short I am not close with them, because of my parents ways, I grew up veryyyy isolated from any sort of family. I dont know anyone on either side and they are strangers to me, (emotionally). My dad has since forced a shallow relationship with them because that is “normal” but truthfully I dont know these people. But like I said my sister and I leasing a car triggered this outrage in my grandma. My sister and I have never leased a car, we haven’t owned a car since we were 20, it broke down and I never was able to get another one. But we (my sister and I) have started jobs and we truly want our lives to start and so we leased a car. And now my dad’s mom is demanding we get kicked out so she could start renting this home. Us being able to afford a 2025 leased car created a narrative for my dads mom that she now deserves some monetary compensation for this home.

My dad’s parents are very traditional, very old school, very by the book. My dad’s dad is almost 90 and my dad’s mom is late 80s. They both recently have had health concerns where their age is now getting the better of them and need to hire a full time nurse. Even so, my dad’s mom is asking for us to leave the home so they could start receiving passive income. This all sounds insane i’m aware but i’m being extremely blunt with this situation. The context I added may not of been necessary but I wanted to paint the whole picture to see if this chart can see my dad’s mom being stubborn, petty or serious about her new claim. What does this chart say, will I be kicked out of my home? If this house cant be rented due to it’s nature, will we have to sell it soon?
