Valuation/Assessment/Tax
Notice of Property Value

Each January Finance mails New York City property owners a Notice of Property Value (NOPV). The notice shows the information that Finance has about each property, including building size, lot size, tax class, construction year, etc., as well as Finance's estimate of the property's market value. The notice explains how your property's estimated market value is established and how that market value determines your property tax.

Estimating Market Value
There are three approaches to determining property value - Sales comparison, Cost, and Income capitalization.

Rolling Sales Update
