You are correct in that if you co-sign they would come after you if there was any default on the lease. You would not be able to evict the person if you were merely the co-signer and not the co-lessee. Your only way to recover any money owed if the landlord comes after you for payment would be to sue this person. I never recommend co-signing for friends or boyfriend/girlfriend.
