Pre qualification letter

[Juan Alvarez]

Please explain the pre qualification process on a loan. I currently filled out a questionnaire from a broker but now he is asking to completea , “document checklist with a list of documents needed for your loan qualification once you find a house. “ can I submit that even though I have not started looking? I thought that was purpose of a pre qualification letter; to Show an agent proof that you qualify. Please clarify. Many thanks.
