After earning a BS degree from Cornell University, Whiting established an import/export company in Hong Kong and in 1992 joined W.P. Carey as an acquisitions associate. He went on to earn an MBA from Columbia University's School of Business, rejoining the firm in 1994 as a second vice president. Since then, he has served as vice president, first vice president, executive vice president and portfolio manager of the fund, as deputy director of acquisitions for WPC and in other senior positions.

Commenting on the promotion, chairman William Polk Carey noted that Whiting had overseen growth of one of the company's most successful funds, diversifying its portfolio by tenant and property type and by tenant industry.

WPC is one of the largest lessors of net leased corporate real estate. It typically acquires single-tenant properties valued at more than $5 million that are leased to corporations for terms of 10 years or longer.
