This document discusses methods for estimating the income and expenses of a real estate property to determine its value. It describes how to calculate potential gross income, vacancy and credit losses to determine effective gross income. Operating expenses like management, taxes, insurance and reserves are then subtracted to get net operating income. This income can be capitalized using market rates or discounted in a cash flow analysis to estimate the property's worth. The document provides an example analysis that values the property at $80,000 using direct capitalization and $103,000 using discounted cash flow.
