The DOR Real Property Verified Market Sales datalayer shows data from the DOR Division of Local Services Bureau of Local Assessment. BLA uses Property Sales Reports (the LA-3) to conduct assessment/sales ratio studies.

Beginning with FY 2010, the Bureau of Local Assessment is requiring annual sales submissions by all communities; these sales will be used to automatically generate sales statistics for certification, interim year adjustment (the LA-15) and the EQV process. In order to conduct an accurate study, data needs to be submitted on all sales over $1,000. A tabular version of the dataset can be accessed at An OLIVER-based interactive online mapping application to filter and map the data can be accessed at

Data are based on an extract from DOR on March 2, 2012 and represent sales from 2001 to third quarter 2011.

The layer is named DOR_LA3_PT.
