Would you live here ?

I have 2 kids and I’m trying to find somewhere affordable I can move to . Someone told me they have a duplex that they live in for $500 and the other side is empty and we can move into there . The only thing is that it’s a 1 bedroom 😭 BUT was told the basement is big and nice and can basically be a bedroom . Now I was like fuck no at first cause you know the sound of having a bedroom in the basement .. BUT for $500 I’m starting not to mind .. would you ? Or no ?

Edit : Kids are .. Girl-turning 4 boy: turning 2

Edit again : maybe I should’ve been more clear about what I was saying . The basement will be MY room . Not my kids they will have the bedroom
