You're looking to move out of your rented property (lease has ended).
Agency fees are all £500-600+.
You'll know you'll fail the credit check anyway because, life.
Can't extend your overdraft, can't get a loan or CC, can't stay with family.
Rent is not a problem (can afford it now and will be able to afford once moved), but the fees and associated costs make moving an impossibility.
No entitlement to benefits of any kind.
What do you do?
