NPVal evaluates a vast array of office real estate - from high-rises to suburban offices, and everything in between. Our founder, Darin Dalbom, MAI specialized in office building valuation in the Washington D.C. market for eight years prior to moving to Oklahoma in the late 1990s. Our deft grasp of office valuation metrics is rooted in longtime understanding of office fundamentals. Recently, we appraised numerous office properties whose landlords are responding to structural changes in office demand initiated by the recent COVID crisis. We are well versed in coworking strategies which have evolved in response to this influence. Our industry-leading experts excel in valuing various types of office properties in step with evolutionary change in demand for this property type.
