Specializing in La Mesa real estate within the Mt Helix area and the 91941 ZIP, Paul Hahn holds California DRE license #00474104 through Coldwell Banker West on Grossmont Summit Drive. Investment-property transactions involve coordinated tax strategy with wealth advisors such as Blue Summit Wealth Management, aligning 1031 exchange timelines with broader portfolio diversification goals. The practice covers single-family homes, vacant hillside lots, and estate properties along Fuerte Drive, Avocado Boulevard, and the residential streets radiating from Mt Helix Park. Hahn partners with Rachelle Hahn (DRE #01949511) and Sarah Cummins to form a multi-agent team handling concurrent listings and buyer representation across the Mt Helix, La Mesa Village, and Casa de Oro districts. Contract disputes and boundary issues arising from hillside lot sales are referred to local real estate attorneys like Brown & Farmer for title-exception resolution and easement negotiation. Most complex listings include non-standard Mt Helix parcels requiring engineered retaining-wall certification, private-road maintenance agreements, and fire-severity-zone disclosures under California Public Resources Code Section 4291.
