RegWatch pulls DOF data including assessed value, market value, tax class, annual tax amount, outstanding DOF balance, tax liens, exemptions (STAR, 421-a, J-51, ICIP), and historical assessment trends.
Outstanding DOF balances can become liens. The annual tax lien sale transfers collection rights to private investors who can charge interest and ultimately foreclose. Understanding a property's tax position is critical for any transaction.
RegWatch combines DOF tax data with ACRIS title records and ECB fine data to give you a complete picture of financial encumbrances. Our tax liability scoring helps identify properties at risk.
DOF assesses properties based on tax class, comparable sales, income approach (for commercial), and other factors. Assessed values are published annually in the NOPV.
NYC annually sells liens on properties with unpaid taxes, water/sewer charges, or other municipal debts. Buyers can charge interest and ultimately foreclose if the debt isn't paid.
Enter any address into RegWatch to see the current DOF balance, tax lien status, and historical tax data.
Common exemptions include STAR (homeowners), 421-a (new construction), J-51 (renovations), ICIP (industrial/commercial), and various religious/nonprofit exemptions.
