Am I thinking too harshly of my mom?

So my family is in a tiny apartment. My mom took it over from grandparents because they had to go a nursing home. She sleeps on the couch and I do too when I come to visit from college out of state, while my younger siblings are in the rooms. The apparent is just gross. A lot of things need to be remodeled and it’s just too small for us. There’s been things leaking and messing up. Just bad. My dad is in another state building a house but only for renting it out to people. When my dad comes to visit my family he just sleeps in hotels or at his family place. My dad was supposed to get us a new house for them to own, but he didn’t.

My siblings have even been complaining when they’re going to get out of this crappy apartment. My little siblings hate they go to the most awful school in the city. There’s high crime here. But my mom also doesn’t want to move because my brother would have to change schools and he wouldn’t be able to play sports. I think that’s only the case if your past school is the same division? My mom just says it’s my dad’s fault they’re stuck here. Ok yes my dad is terrible but I think she needs to stop relying on him and listening to him. I’m just thinking what do you expect? He does this all the time. At this point you need to do something.

I told her just to rent a better place. She says no there’s no point of renting anymore, but she’s paying almost $1k for this crappy apartment when I saw even 4 bedroom houses for a rent of $1.5k. She just wants to live in a crappy situation to stick it to my dad in hopes he’s going to change. I think it’s just a lot of stupid decisions from parents. My little siblings are begging her to move and she just tells them, “ask your dad!” They already did he doesn’t care. They have been there for a year. They thought it was temporary but nope my dad stop them from getting a new house.

I’m thinking of just transferring to an in state school and find a job here to get my family out of this apartment. Definitely am if they aren’t out of this apartment spring break. But I’m sad I will have to give up sports and the friends I’ve made. I’m being selfish maybe, maybe I don’t understand because I’m younger? I hate going back to this apartment during break. I actually would miss my small dorm and bed. I had a roommate but I still got more privacy and slept in better than my mom waking me up blasting tv in the morning on a weekend.

Tldr; my dad is totally useless my mom knows this, but still refuses to take it in her own hands of finding a new place. Me and my siblings have been complaining we are still in this ghetto apartment. So I’m just going to transfer next year and get a job and help my family move out because my dad isn’t helping and my mom is just giving up.
