Founded in 2004 as an independent brokerage, Mar & Mar Realty in Chula Vista's Third Avenue Village operates from Suite F at 1229 Third Avenue in the 91911 ZIP code. The firm handles residential purchase and sale transactions in the western Chula Vista corridor, with title clearance and escrow services for closings coordinated through First American Title Company. Listing activity concentrates in the 91910 and 91911 ZIP codes covering the walkable Third Avenue district, the Broadway corridor near Chula Vista Center Mall, and neighborhoods along H Street west of Interstate 805. Pre-sale exterior refresh on pre-1980 housing stock along Third Avenue and the surrounding residential blocks involves painting contractors including Montgomery Paint Contracting to maximize curb appeal ahead of MLS photography and the South County Caravan tour cycle. Highest-value engagements include multi-family investment transactions on pre-1970 parcels requiring seismic retrofit disclosure under California Senate Bill 1604, lead-paint federal compliance documentation, and Mello-Roos assessment proration calculations at close of escrow.
