Kate Gillingham Milke is a licensed California real estate broker (DRE 01782461) at Coronado Island Realty, the brokerage her father Dave Gillingham founded on Ninth Street in 1995. Born and raised on Coronado Island, she earned her salesperson's license at 18 and her broker's license after graduating from the University of San Diego in 2009, building transaction experience through the 2009 recession that now spans traditional sales, 1031 exchanges, trust and probate dispositions, and pre-listing renovation consulting with island contractors including Mark Stangl Construction. The National Association of Realtors selected her for its 30 Under 30 class of 2015 and featured her on the cover of REALTOR Magazine that year, recognition rooted in her depth across Coronado Village single-family homes, Coronado Shores condos, and rental-segment properties near Orange Avenue. Coronado Island Realty's in-house property management and staging divisions allow her to coordinate lease-up, vacancy marketing, and turnover maintenance under one roof, with homeowner's insurance placement handled through island agencies including Pronto Insurance Agency. Her current residential portfolio includes Coronado homes for sale ranging from entry-level village condos to multi-million-dollar waterfront estates requiring complex HOA transfer documentation and Coronado Cays dock-slip assignments.
