Situated in the heart of the Inland Empire – one of the most dynamic industrial markets in the United States – 1500 S Haven Avenue stands out as a first-class, 45,000-square-foot office building. Its location adjacent to Ontario International Airport and surrounded by corporate heavyweights such as Target, Electrolux, and UPS gave the property strong tenant appeal and sustained high occupancy.
Economos DeWolf was engaged to market the building and address a key challenge: convincing office-property investors that an industrial-centric location could continue to support long-term office tenancy. By presenting historical occupancy reports and comprehensive tenancy studies, Economos DeWolf demonstrated the property’s resilience and value.
The strategy succeeded, culminating in the sale of the building to an Orange County–based office investor for $9.1 million.
