The following online tool provides a replica of the ‘Create New Loan’ screen in the Freddie Mac selling system. You may use this tool to explore the Uniform Loan Delivery Dataset (ULDD) field names as they appear in the selling system.
When you click on a ULDD data-field name, a new window displays the definition, valid values, when and how to use the data point and the Sort ID number. If you need further clarification regarding a data point, you can use the Sort ID number to locate the data point in Single-Family Seller/Servicer Guide (Guide) Chapter 17 or Appendices A and D, as applicable.
This field level help is available in the selling system both customer test environment and live production.
