The document discusses the advantages of using Income-PIE software over Excel spreadsheets for real estate feasibility analysis. It notes that spreadsheets are prone to errors, time-consuming to build and maintain, difficult to standardize across projects, and cannot easily handle multi-phase or complex financing structures. In contrast, Income-PIE automates cash flow projections, standardizes outputs, allows easy comparison of scenarios, incorporates debt and equity schedules, and facilitates partnership deals - enabling users to complete analyses more accurately and confidently in less time. A customer quote endorses Income-PIE as the most practical cash flow application for development analysis and negotiations.
