Are account holders with a bank better able to receive a loan from that bank? 
Banks are businesses, and as such should have the right to refuse service, so they should probably be able to choose one customer over another at will.   [I say "should" because business owners protecting themselves against litigation related to discrimination could restrict their freedom as business owners.] However, banks are businesses and if the customers are identical, both will be approved (or not) according to credit records.  Does not make sense to approve one person with a given credit record and refuse someone with a similar record.  Unless they barely qualify.  Since no two credit histories are identical, there are surely edge cases. Finally, if a customer is a long term customer with large deposits and/or significant amounts of business with the bank, the bankers will likely be inclined to do more business.
