Abstract: A system and method may aggregate into a data structure property information from multiple databases, e.g., from all records included in those databases, and upon selection of any subject property or a characteristic thereof curates the often imperfect and discrepant property information to create suggested values. Similarly, the system and method may perform an on-the-fly evaluation of any characteristic of a selected record, when the property information for that characteristic includes an unlikely value, by triggering from the data structure a dynamic extraction of property information corresponding to a subject property of the selected record, where the dynamic extraction further generates and compares a suggested value to the unlikely value.

Abstract: An automated valuation model and corresponding analysis tool that graphically displays value history information in association with a subject property is disclosed. In one example, the tool generates a graph plotting the valuation history of a subject property over an adjustable time range in relation to a general price index for a pertinent geographical area. When looking at an appraisal for a property, the graph also supports selective plotting of appraiser-selected comparable properties' valuation histories against that of the subject property. The valuation history for comparable properties can be scaled on a pro-rata basis according to the percentage of the adjustments made within the appraisal. In addition, the graph selectively incorporates model-generated comparables and their valuation histories.

Abstract: Tools for analyzing sub-markets corresponding to subject properties are disclosed. An initial pool of property sales is determined as a general market for a subject property, according to property characteristics. Interfaces are provided to allow revision of the property characteristics to iteratively flexibly define new sub-markets for the subject property. A map image is displayed depicting the subject property along with properties included and excluded from the current sub-market. Additionally, a graph image depicts sale price versus hedonic price for each property. Boundary lines are provided in the graph image to depict sales price outliers among the results for the current sub-market. The distribution of any selectable property characteristic for the general market and the current sub-market can also be displayed in a graphical image. Interfaces allow the user to investigate individual properties (e.g., outliers) and to selectively include or exclude any given property.

Abstract: A subject property and a corresponding updatable pool of property sales are displayed in a map image. Property characteristics that define the pool of recent sales are manipulated using an interface that lists the characteristics and provides updatable ranges. Once a satisfactory set of ranges is established, the corresponding sub-market for the subject property is recalculated using only those properties that satisfy the new property characteristics criteria. A map image automatically updates to show those properties included in the updated pool, and those that were excluded. A model-based valuation also automatically updates and is listed among property data for the subject property.

Abstract: The present invention relates to a mapping and comparing choroplethic housing statistics. In one example, this comprises accessing property data corresponding to a geospatial area. Analytics are used to generate usable property data statistics from the accessed property data. A thematic map image based on the usable property data statistics is then generated according to comparison categories, so that the thematic map image may be displayed.
