New York City Property Tax Assessment Records

2022 assessment data for New York City real estate properties used to calculate property taxes and determine eligibility for exemptions. The dataset is maintained by various city employees, including property assessors and exemption specialists. It was last updated in May 2022.

Use Cases

• Predict current total assessed value (CURAVT) from lot size (LND_AREA), building class (BDEP_DEC), and year built (YRB).
• Analyze the relationship between property owner (OWNER) and the value of tax exemptions (FN_EXL_A).
• Model the distribution of land value (CURAVL) versus total value (CURAVT) across boroughs (BORO) and zip codes (ZIP).
• Identify irregularly shaped lots (IRREG) and their impact on assessed value per square foot.
• Forecast future assessed values using historical year ranges (YRA1_RNG, YRA2_RNG) and assessment periods (AP_TIME).

Strengths

• Contains 29 distinct columns covering property characteristics, ownership, and valuation details.
• Data is sourced from official city processes involving assessors and building department reporting.

Limitations

• Sample size and total row count are unknown, limiting assessment of statistical power.
• Data may have geographic bias, covering only New York City properties.
• The last update was in 2022, making the valuations potentially stale for current market analysis.
