California DRE license 02100243, displayed inside the registered business name itself, identifies Sofia Arthur as a Compass Realtor at Armstrong & Associates' 1920 Fort Stockton Drive office in Mission Hills 92103. Arthur's bilingual Swedish-English background and San Diego State University degree in Business Management with a Human Resources emphasis translate into relocation support for Scandinavian expats and HR-transfer buyers, routed through team lead Todd Armstrong & Associates at Compass. A prior career in corporate human resources shapes the client communication rhythm: standardized check-in cadences, written expectation documents, and formal post-transaction debriefs replace the ad-hoc texting model common to newer agents. Buyer representation focuses on first-time purchasers facing the statistic that 44 percent of buyers feel anxious through escrow, with HR-trained communication tools built to flatten that curve. Listing prep leans on Compass's marketing platform and neighborhood-specific copywriting, with commercial and editorial listing imagery produced by Mission Hills photographer David Hartig, Photographer | Corporate, Commercial, Editorial. The most involved deals are international Scandinavian buyer transactions where foreign-source-funds documentation, FIRPTA planning, and remote e-signature coordination all have to be resolved before a US-based escrow can close.
