A period of increasing economic activity or a general economic upturn, typically following a stabilization of key sectors and industries, marked by increasing sales and recovering prices in real estate markets as a direct result of an external shock (for example, a favorable tax code revision) or an increase in demand for commercial real estate which, in turn, leads to the absorption of excess space.  Little or no construction occurs during the initial stages of this phase until most of the excess space is absorbed or until reasonable financing opportunities become available.
