History Sandstone Properties, Inc. was founded in 1994 by Eri Kroh. What began as a single, personally funded investment in Santa Monica has grown into a $650 million portfolio including a broad spectrum of office, retail, industrial, multi-family and hospitality real estate. Our Unique Vision Our founding vision has molded our unique approach to real estate investment. Rather than investing in “what is,” we look for under-performing properties and ask ourselves “what could be?” This vision is not learned, it is mastered through decades of experience and knowledge of the industry and city in which we operate.
