global class LoanOfficerBatch implements Database.Batchable<sObject> {

You seem to be already getting it. Once a Lead record is converted to an Opportunity the following fields on Lead are populated with the Ids of records created or merged during conversion, before conversion these fields are all null  - 

ConvertedAccountId - Id of the Account
ConvertedContactId - Id of the Contact
ConvertedOpportunityId - Id of the Opportunity
