Answer
How to verify a mortgage license (NMLS number search)
Every loan originator and mortgage company in the U.S. has an NMLS number. Search it at nmlsconsumeraccess.org to see licenses, states, and any disciplinary history. Washington also lists licensees at the Department of Financial Institutions.
Ours: Mortgage Lending Group, Company NMLS 1157983. Enrique Pelayo Jr., NMLS 131435, Accredited Mortgage Professional. Licensed in Washington.
A legitimate lender will put these numbers on every page, email and letter, and will never ask you to pay a fee before pre-approval.
