Hans Merklein operates Merklein Real Estate from 2700 Adams Avenue in Normal Heights, San Diego, where he has held a California DRE license since 1978 — a 47-year tenure that spans every major cycle in the San Diego residential market. Merklein earned degrees in Finance and Economics from San Diego State University and the University of San Diego, and he brings a prior career as a research analyst at CoStar Group (1997-2001) to his listing and buyer-representation work. That commercial real estate research background informs his comparative market analyses for residential transactions in the 92116 ZIP, particularly in the Craftsman and Spanish Revival housing stock along Adams Avenue between Felton Street and 33rd Street. Buyers securing financing for Normal Heights properties coordinate pre-approval timelines with lenders including Trevor Gravink, a mortgage consultant operating within the neighborhood's lending network. Merklein currently operates under Big Block Realty Inc., an independent San Diego brokerage, and his transaction coverage extends across the mid-city neighborhoods that border Adams Avenue — including University Heights to the south and North Park to the west. The 2700 Adams Avenue office sits at the western end of Normal Heights, one block east of where Adams Avenue crosses into North Park, positioning the practice at the seam between two of San Diego's most active resale markets. Sellers preparing a property for market contract renovation and repair work through general contractors including PBH Builders, a general contracting firm in the same neighborhood. Merklein supports Children's Hospital, Wounded Warriors, and the Surfrider Foundation through personal philanthropic contributions.
