Margaret Biolos represents buyers and sellers in Point Loma through Coldwell Banker Realty's Shelter Island office at 2727 Shelter Island Drive, positioning her practice at the entrance to the marina district that defines Shelter Island's waterfront real estate market. That Shelter Island address gives her direct proximity to yacht-basin properties where marine-insurance considerations — handled by specialists like Douglas K Smith Marine Insurance — factor into the purchase calculus for waterfront homes with dock access. Her listing territory covers the La Playa neighborhood, Shelter Island Drive condominiums, and the broader Rosecrans corridor, where Coldwell Banker's Global Luxury marketing platform extends exposure to international buyer networks. Trust and estate dispositions on Shelter Island properties coordinate title clearance with Point Loma attorneys such as Conscious Legal, whose practice handles the probate-court filings that precede listing activation. The most complex transactions involve waterfront properties along Shelter Island Drive where submerged-land lease renewals, Port of San Diego tidelands regulations, and coastal-development permitting add regulatory layers beyond a standard residential close.
