How to Use Our Historical Assessment Data

Lenders, appraisers, servicers, insurance companies and others use our historical assessment data for numerous applications that require researching historical and current property details or helping to gain deeper insights into trends that directly impact today’s property decisions.

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building permit data to conduct a deeper evaluation of lawful property improvements or to identify properties that are out of date with current major building code requirements.
