Dual-licensed as both a real estate broker (DRE #02008965) and mortgage loan originator (NMLS #1898109), Margaret L Harris at Finest City Homes & Loans on Second Avenue in downtown San Diego's Bankers Hill combines purchase representation with in-house loan origination. Seller clients preparing Bankers Hill properties for market coordinate pre-listing renovation scoping with contractors like Sheiner Construction for whole-house upgrades that maximize appraisal value before MLS launch. The women-owned practice operates on a referral-only model within a brokerage carrying more than 75 combined years of real estate and mortgage experience, with Harris holding credentials from Kaplan College San Diego's real estate program. Pre-sale cosmetic preparation for downtown listings includes interior and exterior paint coordination through firms like CertaPro Painters of La Jolla and Central San Diego for color-matched touch-up and full-unit refresh scoping. Highest-value transactions involve simultaneous loan origination and purchase representation where Harris underwrites the buyer's mortgage through Finest City's NMLS-licensed lending division while negotiating purchase terms, requiring Chinese-wall compliance protocols and dual-capacity disclosure under California Business and Professions Code Section 10177.
