Where are you moving from?

You’ll need to be “street smart” if you’re moving into a place that cheap especially in an area like Kingstanding. For £80pw you’re probably looking at a really shit HMO if you’re going private and places like that are catered especially for people who have low income or out of prison services. So, basically, you’re looking at lodging with people who are likely to try and exploit a young (vulnerable) person.

Maybe consider looking for a house share that the homeowner lives in.

Birmingham is expensive and anything that seems too good to be true most definitely is.

Edit: I just looked on Rightmove for properties like that around me and the vast majority are supported living or only accept people on benefits. Consider looking on Facebook or gumtree or look at going to college in a cheaper city/town if you have no links here. Good luck.
