For bilingual real estate representation in downtown San Diego and East Chula Vista, Jorge Castellon holds a California DRE Broker's License obtained in 2007 and operates through Compass from 401 West A Street. A San Diego State University School of International Business graduate, Castellon entered the mortgage industry before transitioning to brokerage, giving him underwriting-level fluency in loan qualification, debt-to-income structuring, and interest-rate lock timing — expertise that complements the renovation scoping performed by Apex Ridge Construction in Middletown when pre-sale improvements require financing. The practice has closed over 300 transactions spanning downtown high-rise condominiums, East Chula Vista master-planned communities including Eastlake and Otay Ranch, and single-family homes across Mission Hills and Del Cerro. Fluency in English and Spanish allows Castellon to serve the 92101 ZIP code's bilingual buyer and seller base, including foreign national purchasers navigating ITIN-based lending and cross-border title requirements. Move-out turnover coordination for sellers includes scheduling deep-cleaning services through providers such as Coastals Cleaning Services to deliver showing-ready condition before photography and MLS activation. Simultaneous close-of-escrow transactions in which a Chula Vista seller's proceeds fund a downtown condo purchase — requiring dual title searches, synchronized contingency removals, and back-to-back settlement-statement execution — represent the most timing-critical closings in the portfolio.
