Great question. A Key Performance Indicator, irrespective of the industry, is a measurable value that, at a glance, shows how effectively a commercially active entity is meeting its business goals. In most cases, more than one KPI (viewed together) are necessary to create a clear picture. Naturally, every organization or individual performs at different levels, so the relevant KPI’s connecting to these play a vital role. The more KPI’s you see, the better. As far as real estate wholesaling and investing goes, it's a vibrant and mainstream economic activity. Therefore, KPI’s like "ROI per deal" or "Leads per Employee" amongst many can help you to elevate performance substantially.
