Interest rates are among the top concerns for office investors this year. This year, interest rates are expected to increase nominally several times. The incremental changes in interest rates could have a big impact on the capital stack for investors, according to Tim Lee, VP of corporate development and legal affairs at the Olive Hill Group. The firm has been very active in Los Angeles, but is shifting its strategy this year to look outside of the California market. Although it is optimistic about the year ahead—Lee says that the fundamentals remain strong—interest rates are one of its top concerns.
