Abstract: A system for and method of providing a listing of available rental properties in a particular area, and an improved graphical user interface for viewing and management of the listed properties. The system/method automatically adjusts pricing for different time rental periods for different months when the rules are modified for a Reference Month or a “driver period” within a month. It automatically calculates and populates nightly calendar pricing and formulas or percentage relationships for different rental periods in each month and recalculates estimated monthly income based on the dynamic changes that the owner may enter for the owner's income goals, availability of the property, Premium Night rates, minimum length of stay, minimum monthly income and other parameters.
