The loan might be at no interest. If the employer doesn't normally pay for relo, it's up to you to start the discussion. Some employers have the attitude that if a candidate won't relocate himself or herself, the person isn't motivated enough for the job. They use the relo issue as a test. I think this is nonsense.
Relocation is mostly a financial issue, and that means it's probably negotiable.
Ask what their policy is. If there's no relo program in place, indicate your willingness to negotiate mutually acceptable terms and proceed with your interviews. Then be ready to put options on the table and negotiate. I wish you the best. I have about two years' experience in this field and a two-year degree in graphic design.
