My roommates are moving out. We share an apartment of 3 bedrooms, shared kitchen and bathroom.
I don't want to move as there isn't much available, but they can't afford to live here with me.
If the ones I rent off can't assure there won't be two guys moving in their rooms, do I have to move as well?
Is it haram to live with two boys is what I am asking?

Yes, it is haram to live with non mahram males.
