Need help deciding on moving

Ok this is gonna be a long one, but I have to rant and ask everyone because we are having the hardest time making this decision.

I’ve lived where I live now for 7 years. In a mobile home that my mom owns. I live here with my current boyfriend. It’s all paid for so all we have to pay is the lot rent to the mobile home court and utilities. Lot rent just went up to $350. With rent and utilities and other bills we have we pay anywhere from $800-1000 a month. So as far as money goes, it’s nice. It’s a 3 bedroom 2 bathroom. It’s a newer mobile home (a 2005) but it could still use some work/cosmetic updates. The reason my mom still owns it and not me is because honestly I’m 25 and at this point in my life I’m not ready to own a place. That’s just me. It’s just not a priority for me at this time. Some day it’ll be the right time to own wherever I live, I just know it isn’t now. Anyway, with all that being said, I really want to move somewhere else. Its been great living in the mobile home for the most part because it’s spacious and we have pets and it’s a lot less expensive than most everywhere else in this area. But after 7 years I’m just ready for a newer, nicer, more updated space and change. My boyfriend and I went to look for places and found one we really like. We got approved and now we are having 2nd thoughts and I can’t make this decision..😩😩 the new place is a town house, it’s a little bit of a downsize cuz it’s 2 bedrooms 1.5 bathrooms, but it’s newer-Ish and nicer/more updated. However with that obviously comes more expenses. If we moved it’d bring our monthly bills to about $1500-1600 each month rather than $1000 max where we’re at. That is definitely do able for us, but what we can’t decide is if we WANT to do that. If we stay where we are then that $500 extra a month really could go towards a lotttt of other things the more we think about it but this other place is so nice we’re scared to lose out on it. I’m so torn from going back and fourth it’s making my head hurt. I know nobody can choose for me, but if you were me, what would you do?!!?
