Teri Parker of Parker Properties leads Alpine's longest-running independent brokerage from Suite E at 2101 Alpine Blvd, where she has served as principal broker since the firm's 1999 incorporation. Her residential and commercial listings often require pre-sale electrical panel upgrades to meet current NEC code, with 100-to-200-amp service conversions frequently handled by Arce Electric in Lakeside. The practice covers buyer representation, seller listing, property management, and commercial leasing across Alpine, Lakeside, and greater San Diego County. Pre-listing preparation for the Alpine Blvd corridor's mid-century ranch homes includes deep-cleaning coordination through Alpine Cleaners on Tavern Road to maximize showing presentation. Highest-value transactions involve multi-parcel assemblages requiring lot-line adjustments, tentative parcel map filings with San Diego County Planning, and ALTA survey coordination for properties with easement encroachments or shared-access agreements.
