Cushman & Wakefield's Self Storage Industry Group (SSIG) is an international full-service real estate consulting team specializing in the self storage asset class. We have developed an econometric model to forecast the depth of market demand for self storage which has been used in over 100 major metropolitan markets and in all 50 states of the country. This expertise in a specialized asset class has resulted in key insights into the self storage market and in the publication of the annual Self Storage Investor Survey. The Survey details trends and conditions of the self storage market and highlights capitalization rates, financing and an optimism index. Market analyses and valuation models have been published by Mini-Storage Messenger magazine and their annual Self-Storage Almanac.

Technical experience of the Group includes over 75 years of cumulative real estate experience in consultation, valuation, and management. The scope of the practice has centered around complex valuation, data and research, market analysis and feasibility studies of the self storage asset class. Assignments have included property analysis in a value range from less than $1,000,000 to over $50,000,000 (portfolio) throughout the United States.
