(CHICAGO, IL, Aug. 23, 2013)  Total collections for suburban office complexes nationwide in 2012 increased 2.2 percent from 2011 levels to $18.62 per square foot of net rentable area.  Similarly, downtown properties experienced a 1.9 percent year-to-year collections increase to $20.68 per square foot. Total actual collections for downtown properties were 11.1 percent greater last year than their suburban counterparts, versus 11.4 percent higher the prior year.

These are among the major findings reported in the 2013 edition of the Income/Expense Analysis: Office Buildings, the latest benchmarking study published by the Institute of Real Estate Management (IREM).  This annual research study, conducted by IREM since 1976, analyzes operating income and costs for 1,929 private-sector office complexes – some containing multiple buildings – in major metropolitan areas and regions in the United States and Canada. For the third consecutive year it also contains financial data, broken out separately, for 374 medical office buildings. 

The study is designed to help property owners and managers, investors, appraisers, lenders, developers and other real estate professionals evaluate and optimize a buildings performance.  It is an invaluable resource for building better budgets; identifying ways to trim waste, address inefficiencies and make needed improvements; preparing feasibility studies, appraisals and loan requests; and much more.

Total operating costs for suburban buildings in 2012 increased a mere 0.2 percent from the prior year to $8.34 per square foot of rentable area, while those for downtown properties rose 1.4 percent to $10.09 per square foot.

Nationally, net operating costs for suburban buildings in 2012 dipped 1.0 percent to $5.97 per square foot of rentable area, whereas those for downtown properties increased a mere 0.7 percent to $7.17 per square foot.

Three of five major expense categories for suburban properties decreased slightly last year. Insurance/services costs experienced a 5.7 percent decline, utility costs fell 3.1 percent, and real estate and other taxes decreased 1.4 percent.  On the up side, janitorial maintenance costs rose 3.8 percent from 2011, while administrative/benefits costs equaled those of the year earlier. 

In contrast, all but one of the major expense categories for downtown properties experienced year-to-year increases. Costs for insurance services were up 4.0 percent, those for real estate and other taxes rose 3.1 percent, those for janitorial/maintenance services were up 1.1 percent, and those for administrative/benefits services rose 0.9 percent.  On the down side, utility costs experienced a decline of 6.8 percent from the prior year.

In the aggregate, suburban properties proved 17.3 percent less costly to operate in 2012 than their downtown counterparts, with all expense categories less than those experienced by downtown buildings.

The national vacancy rate for suburban properties in operation for 12 months was 10 percent in 2012, down 1.0 percent from the prior year. Downtown properties experienced an 8 percent vacancy rate, down from 9 percent in 2011.
