Real Estate Data

Real estate data is drawn from dozens of public record systems — county assessors, deed records, building permits, planning filings, and GIS layers. Understanding where it comes from helps you interpret it accurately.

Where Real Estate Data Comes From

The data that powers property intelligence is almost entirely drawn from public records maintained by local government agencies. County assessors maintain parcel records. County recorders maintain deed and encumbrance records. Local building departments maintain permit records. Planning departments maintain application and approval records. Municipal GIS departments maintain spatial data layers.

Each of these systems has its own update cadence, coverage gaps, and data quality characteristics. A county assessor database may be updated annually for tax purposes but lag behind recent transactions. A building permit system may have complete records for the past five years but incomplete records for older permits. A planning department GIS layer may be updated in real time or may lag by weeks or months.

Understanding the source and verification date of any data point is essential for interpreting it correctly. Landexar provides source attribution and verification dates on every data point so you always know the basis for what you are seeing.

Key Concepts

County Assessor Records

Public records maintained by the county assessor containing parcel identification, ownership, assessed value, and property characteristics for every parcel in the county.

Deed Records

Public records of property transfers maintained by the county recorder or clerk. Deed records document ownership history and any encumbrances recorded against a property.

Building Permit Records

Public records of building permit applications and issuances maintained by the local building department. Permit records document authorized construction activity.

Planning Application Records

Public records of rezoning requests, site plan applications, conditional use permits, and other planning filings maintained by the local planning department.

Data Verification Date

The date on which a data point was last confirmed against its source. Essential context for interpreting any property intelligence data.

Source Attribution

The identification of the specific agency, system, or document from which a data point was obtained — enabling verification and assessing data quality.
