Abstract: The present invention is web-based platform for quick evaluation of real estate value. Markets are separated into well defined boundaries. Local real estate professional's inputs are considered while defining these defined individual market locations. A basis property is selected in each of the defined market. Measurable and non-measurable factors are quantified for the basis property. Site value is calculated for the basis property. The site value and measurable factor value is subtracted from the sale price of basis property and the non-measurable factor is proportionately adjusted, so that the total aggregates to sale price of basis property. A visual pattern is created and a database is created having visual pattern of all properties. Subject property input is received, visual pattern generated and comparable visual patterns are extracted from the database. Visual patterns are displayed to the user who can quickly select most appropriate pattern to estimate the value of the subject property.
