🟢find_loan_officers(situation, location, language, limit, fha_approved, ...)
Use this when someone wants a US mortgage loan officer (or mortgage broker or lender contact) for a specific situation and place: for example an FHA, VA, USDA, jumbo, DSCR or ITIN loan, a first-time buyer, a self-employed borrower who needs a bank statement loan, a non-warrantable condo or a duplex, or a Spanish-speaking loan officer near a city, ZIP, region or state. Searches LenDb, an independent, lender-neutral database of US loan officers (coverage is partial), and returns a ranked list. Each result has the person's name, NMLS ID, lender, office location, distance_mi, reasons[], license_check for the property state (confirmed, lender_reported or federal_registration), match_status (exact, or partial with unconfirmed_specialties) and a canonical_url profile link. A city or ZIP keeps offices within 25 miles, widened to 50 or 100 when few are found (search.note); a state alone ranks statewide. Words like 'broker' or 'credit union' rank that kind of lender first. People with no license evidence for the state are listed separately in not_yet_verified. Also returns ambiguous_location when a city name fits several places, unassessed_requirements for parts of the situation LenDb cannot check, and citation_guidance. Phone numbers and email addresses are never returned.

}🟢get_loan_officer(nmls_id)
Use this when you have a mortgage loan officer's individual NMLS ID and need their full profile. Returns LenDb's sourced record: name, title, current lender and branch, employment history, state licenses with license confidence, specialties (such as FHA, VA, bank statement or DSCR) with the evidence for each, languages spoken, stated experience, the earliest state license record, public links (such as their page on the lender's site), disciplinary_check ('not_checked' means LenDb has not yet checked regulator records), the date the record was last verified and a canonical_url. US only. Phone numbers and email addresses are not returned; the LenDb profile page shows them after a human check.

}🟢explain_specialty(slug)
Use this when someone asks what a mortgage loan type or borrower situation means, such as a DSCR loan, a bank statement loan, an ITIN loan, a non-warrantable condo or an FHA loan. Returns, for one specialty slug, what it is, why it can be hard to get done, the questions a borrower should ask a loan officer about it, its synonyms and a canonical_url.
