@Maribel Manibo It sounds like you are already recognizing the pattern in the industry. Before getting my broker's license I spent 10 years working for a direct lender. We are talking nationwide, wholesale, private money with billions in assets under management. This lender got its loans from mortgage brokers it approved to do business with. In that time I learned that the waters are purposely made to be muddy when determining the source of funds. The wholesale lender I worked with offered a table funding program to the brokers in its network. They took steps to help table funding approved brokers feature themselves as the source of funds. Conditional loan approvals and loan applications were white label and loan docs were issued in the table funding broker's name. At closing the loan would then be transferred back to the actual lender. The program was effective at concealing the source of funds and it was implemented to attract mortgage brokers looking to enhance their business. I witnessed several instances where non table funding brokers (approved by the same lender) submitted their loans to other table funding approved brokers. In short, there are a lot of participants in mortgage lending that aren't who they say they are.
Investigate, ask around, try checking the Scotsman guide. Experience and time are the only ways to really be able to tell what's going on behind the curtain. Good luck.
