The data model decisions.
The loan origination system remains the record of truth for applications, pricing, conditions and disclosures, and the agent should read from it rather than from copies that drift. In Salesforce, the useful structure is a lead or referral, a borrower and co-borrower relationship, a loan record mirroring key milestones, and referral partners such as real estate agents and builders. Decide which milestone and condition fields sync and how often, which documents flow back to origination, and which roles, from borrower to realtor, the agent may speak with about a given loan, because privacy rules limit what third parties can hear.
Loan origination systemSupplies milestones, conditions and closing dates to the agent and receives borrower-uploaded documents tagged to the correct loan and condition.
Borrower document portalGives borrowers a secure place to upload files the agent requests, keeping bank statements and tax returns out of chat transcripts entirely.
Loan servicing systemProvides payment, escrow and payoff information for post-closing borrower questions, where the lender services its own portfolio rather than selling servicing rights.
