Where the records are

The county offices an investor deals with in Bronx County, and what each one puts online.

Deeds and mortgages

NYC Department of Finance, Office of the City Register (ACRIS). ACRIS lets anyone search and view deeds, mortgages and other recorded documents for the Bronx from 1966 to the present for free.

Owners and values

NYC Department of Finance, Property Assessments. Assessed and market values, exemptions and tax bills for every lot are free on DOF's Property Information Portal, and the full assessment roll can be downloaded free.

Tax sales

NYC Department of Finance, Lien Sale. DOF posts free lists of lien sale candidates by borough before each sale, but the liens are sold only to one city-authorized buyer, not to the public.

Foreclosure sales

Bronx County Supreme Court, Civil Term. The court posts monthly foreclosure auction calendars online for free.

Parcel maps

NYC Department of Finance Property Information Portal (Digital Tax Map). The free portal shows the official digital tax map with borough, block and lot numbers, lot history and recent recordings for any city property.

How property is sold here

Bronx County follows New York's rules, with its own calendar and offices. Read the New York guide for how the state works.

Tax sales

New York City does not auction tax deeds or sell liens to the public; it sells unpaid property tax, water and sewer liens in bulk to a single city-authorized buyer, and the 2025 lien sale was held on June 3, 2025. DOF posts borough lists of eligible properties on its lien sale page before each sale and mails owners warnings 90, 60, 30 and 10 days ahead. The lien buyer can later foreclose, and those properties are then sold at the court-run foreclosure auctions in the Bronx.

Foreclosure sales

Bronx foreclosure auctions are run by court-appointed referees on Mondays at 2:15 PM in Courtroom 711 of the courthouse at 851 Grand Concourse. The court posts auction calendars monthly, and questions go to bxforeclosure@nycourts.gov or 718-618-1322.

Assessed values

The NYC Department of Finance revalues every property every year, publishing the tentative roll in mid January and the final roll in May for the tax year that starts July 1.

Transfer tax

New York State charges 0.4% transfer tax (more on large NYC sales, plus a 1% mansion tax on homes of $1 million or more), and New York City adds its Real Property Transfer Tax of 1% on homes up to $500,000 and 1.425% above that, or 1.425% and 2.625% on commercial property.

Worth knowing

Bronx Supreme Court posts its foreclosure auction calendars online each month, which the other borough courts were not found to do.

Worth knowing

The Bronx had the largest commercial (Class 4) market value increase on the FY27 tentative roll, at 8.4%.

Worth knowing

The Bronx is coextensive with Bronx County, so city offices handle everything a county would.

Questions

Where are deeds recorded in Bronx County?

Deeds for the Bronx are recorded by the NYC Department of Finance's Office of the City Register through ACRIS, which serves Manhattan, Brooklyn, Queens and the Bronx. Records from 1966 on can be searched free online.

When is the Bronx County tax sale?

New York City sells tax liens, not property, and only to one city-authorized buyer, so the public cannot bid. The most recent sale DOF lists was June 3, 2025, and DOF posts each year's borough lists on its lien sale page.

How do I find who owns a property in Bronx County?

Search the deed on ACRIS for the latest owner of record, or look up the lot on the NYC Department of Finance Property Information Portal. Both are free.

Are Bronx County property records online?

Yes. Deeds and mortgages since 1966 are on ACRIS, and values, tax maps and lien sale lists are on NYC Department of Finance sites, all free. Foreclosure auction notices are published in newspapers and on monthly court calendars.
