Help Wanted: Pre-Qual vs Pre-Approval!? Our struggle to communicate.

I am desperately looking for suggestion to better communicate our Asset Manager’s requirements for a true Pre-Approval vs the canned Pre-Quals we are still getting! Despite the fact that we state in the Private section if the MLS listing that the Pre-Approval should include a “Loan Number, Rate, Term, ....etc”, we are still getting the same Pre-Qual letter from the loan officer in their office! Is it the similarity in the names!? Is it because most realtors don’t know what to ask for from their loan officers!? Is it the culture gap between the lending side and the real estate side of the house!? What is it?! The problem becomes a tactical nightmare when we are getting more than 10 offers per listing and we have to unite the original Purchase contract with the 2nd attempt at getting the pre-approval right! We are convinced that the buyers are put in a difficult position if their agent neglects the financing side of the transaction. Have you figured out how to communicate this requirement!? Please help if you have! Please, please help ………………………………!
