How to Use Our Historical Assessment Data

Identify Home Equity Loan Prospects

Find potential home equity loan candidates by identifying properties that may need improvement: for example, older properties with little or no history of major work, properties with original heating/air conditioning, lower building quality grade and prospects for roof repair, windows, siding, structural improvements, etc.

Enhance Valuation Models 

Improve the accuracy of valuation models by incorporating assessment records data, for example property characteristics, improvements, legal descriptions, sales price, land use and site influence.

Conduct Trend Analysis

Gain better insights into risk such as the potential impact of taxes on defaults, zoning and land usage, site influence, types of improvements and stability of market values.

Evaluate Property-Condition Risk

Combine historical assessment data with Black Knight building permit data to conduct a deeper evaluation of lawful property improvements or to identify properties that are out of date with current major building code requirements.

What is the limitation of the data that is provided by the counties for each year?

The standard property attributes that are captured in the annual county assessment data can vary year to year depending on what information is made available by the county. It is possible for a county to limit or suppress the population of specific data element based on changes in law.

How does Black Knight account to changes in the data identification over the long history of reporting?

Black Knight uses a persisted property ID “DPID” with the assessment history data set which allows linking of properties over time. The common property identifier FIPS and more specifically Assessor Parcel Number (APN) can change from one year to the next due to APN formatting or renumbering changes implemented by the county, but DPID overcomes those APN changes challenges by persisting the ID value.
