Abstract: Certain embodiments of the disclosed technology may include systems and methods for detecting property capital gains. According to an example embodiment of the disclosed technology, a method is provided that includes receiving property transaction information comprising previous owner identification (ID) and property ID associated with a property. The method includes querying one or more databases with the property transaction information, receiving independent data in response to the querying, producing transformed data based at least in part on the independent data and the property transaction information, determining potential property capital gains for the property based at least in part on one or more of the property transaction information, the independent data, and the transformed data, and outputting data identifying the determined potential property capital gains associated with the property.
