2002 was a wait-and-see year for businesses looking to lease new space. Conversely, 2002 was a tremendous year for commercial real estate sales. Lack of confidence in the economy curtailed many planned leasing moves while low interest rates provided an opportunity to buy not seen in 40 years. Rates remain at historic lows as we march into 2003. Do the math. You can buy or build a commercial office building and pay less in mortgage payments than you would in rent. If purchase is an option, this is the best of times.
