Why a seller cares

Every licensed loan officer has an NMLS number, and it is printed on the preapproval letter. Looking it up is a two-minute way to check that the lender on a buyer's letter is real.

A simple example

The preapproval names a loan officer and an NMLS number. The public lookup confirms the license and the company.

That NMLS approves loans. It licenses the people who make them; it says nothing about a particular buyer's approval.
