Based on recent market conditions, London Group’s income data for properties listed assumes a cap rate of 6.35 percent.

Which of the dozens of gleaming Class A office properties in San Diego County generate the best returns for the owners?

To answer this question, the San Diego Business Journal commissioned the The London Group Realty Advisors, a San Diego-based real estate consultancy, to conduct an exclusive research effort assessing the class A office properties in selected submarkets. Using data from the CoStar Group combined with other industry and public data, the London Group estimated the net operating income (NOI) of dozens of buildings in the region. From that list, it selected the top performers in the downtown, UTC, Carmel Valley and Mission Valley submarkets.

The top performers in each submarket by net operating income per square foot were:

• Downtown: DiamondView Tower with a region topping NOI of $33.70/sq. ft.

• Carmel Valley: One Del Mar, with the second-highest NOI of $30.01/sq. ft.

• UTC: 4225 Executive Square generates an NOI of $24.58/sq. ft.

• Mission Valley: Hazard Center Office Tower with an NOI of $18.51/sq. ft.

These numbers are something of a surprise. As the top performing building, DiamondView Tower — while downtown — was not in the city center where many high-rise office towers are clustered. More importantly, the performance of the region’s leading Class A building reflects a unique locational relationship that reinforces the first rule of real estate: location, location, location. In this case, while the building’s location is somewhat off the beaten path, neighboring real estate in the form of Petco Park brings unique value that is reflected in the net operating income the building generates.
