Bulgarian-born, California technology pioneers Ivan and Lilian Vachovsky have sold a Phoenix data center and bank vault buildings for $1.3 million.
The Vachovskys emigrated to the U.S. in 1992 from Bulgaria. The computer engineers have owned computer and Internet ventures in San Diego.
They also own San Diego-based Litmath LLC which sold two buildings near Interstate 17 and Osborn Road.
The 120,000-square-foot properties were sold to San Diego real estate firm Fenway Properties for $11 per square foot.
Phoenix has a strong data center market thanks to available and cheap commercial real estate, stable power supplies and lack of natural disasters. The Interstate 17 corridor has call centers, data centers and other back-office operations.
