Planning to move out but can’t agree where to move to and it’s causing friction

I’ve been living with my mom for a year or so with my SO but my mom has gotten tired of living with all of our dogs. Some of them like to rough house and her dog sometimes barks at my SO frequently and that upsets her. She also doesn’t like our backyard the fence has multiple holes in it and our neighbors dog keeps jumping the fence to get to my dogs.

Anyway, the place I had narrowed down to it possibly being a good one was one my SO does not agree with. The cost for rent is around 1150 a month and he feels we could get a better deal elsewhere. However he doesn’t consider the other buildings not having a fence or sharing a backyard with others a problem but my mom does and idk id like a fence as well one of our dogs escaped and we had a fence!

So imagine how hard it would be to keep track of them with no fence? And perhaps it’s winter and cold and we don’t want to stand there and hover over them? Then he was also looking into a trailer home but I have never desired to live in a trailer home then he suggested a one bed room as well.

It’s troubling to me that it seems like he isn’t considering the living environment just because the price that is the cheapest it can be. For the one bed room he was like oh wow it’s only $250 like yeah it’s probably a shit hole that’s why. Probably infested with bugs and breaking down.

No offense to anyone with a one bed room but we will have two kids soon. I don’t want them growing up in a shoe box just so we can penny pinch and for what? Have a few extra bucks to spend on food which is what we do now with our money since living with my mom? And I mean I guess we’d get our own groceries and pay the utilities but idk I don’t really have other bills like a phone bill or car insurance or a payment. So I feel like the extra money is spent on things that don’t really hold substance.

So to him he thinks it’s dumb to move to the house that costs 1150. I had wanted to move there because it’s right beside my mom and she could help out with my daughter when I need it since I work 12 hr shifts and his job also can be 12 hrs depending on the work load.

There’s another personal reason I’d like to stay close to my mom…the relationship with my bf has gotten physical at times during disagreements. This happened in the beginning and across our relationship. Sure it’s not an everyday thing but it’s unpredictable. It has happened enough times that I worry about living alone with him. So I thought living right next to my mom would help me feel safer and if I’m in trouble she’s right there.

Idk I just feel like I’d be more open to moving to someplace perhaps cheaper that isn’t right next to my mom later on once I see how he behaves when we aren’t living in the same house as her. Because they say abusers tend to isolate their partners and continue the abuse but perhaps worse than before because there is no one else around. And then they get comfortable since they think you’re in deep with them by living alone with them.

So my conundrum is do I go with my SO and attempt to locate a cheaper place that isn’t as a nice as the one I found next to my mom? Or do I move into the nice more expensive place on my own, because according to my SO he says he isn’t moving in with me if that’s my decision and he’ll go his own way. It’s just difficult for me because we are expecting another child and daycare is expensive and other things as well for a new baby won’t be cheap.
