Overview
NYC Property Sales Scraper
Scrape NYC property sales records from the official DOF Rolling Sales dataset, up to a million per run. Every sale includes price, address, borough, tax class, and building details. No API key or registration. Export to CSV, JSON, Excel, or XML.
The NYC Department of Finance publishes every property sale as a public rolling sales file, but the raw data is a large, periodically updated spreadsheet that is hard to filter and query. This Actor reads that dataset directly, lets you narrow by borough, and returns each sale as a clean, flat row you can download immediately. No manual downloads, no parsing PDFs, no wrangling Excel files.

| Appraisers and assessors | Pull verified sale prices and property details for valuation reports. |

Troubleshooting
Why am I getting fewer results than my maxItems setting?
The Actor returns only the records available in the current DOF file. If you set maxItems to 100,000 but the borough you selected has only 5,000 sales, you will receive 5,000 rows. Try removing the borough filter to pull from all five boroughs.
Why are some sale prices zero or blank?
The DOF dataset includes non-arms-length transfers such as foreclosures, estate settlements, and nominal transfers, which may show a zero or blank sale price. This is normal and reflects the source data.
The run timed out. What should I do?
Large extractions can take time. Try reducing maxItems or filtering to a single borough to keep the run within Apify's memory and time limits. You can also increase the run timeout in your Actor settings.
Why do I see duplicate sales?
The DOF occasionally lists the same property transfer more than once, especially when multiple lots are involved. Deduplicate on the address and sale date columns in your analysis tool if needed.
The data looks different from the last time I ran this Actor.
The DOF updates the rolling sales file periodically, and older records may be revised or removed. Changes in the output reflect updates to the source dataset, not a change in the Actor.
FAQ
| Question | Answer |
|---|---|
| What is the NYC DOF Rolling Sales dataset? | It is the official public record of every property sale in New York City, published periodically by the Department of Finance. It includes sale price, date, address, tax class, building dimensions, and other characteristics. |
| How often is the data updated? | The DOF publishes new rolling sales files several times a year. This Actor reads the latest available file each time it runs, so you always get the most current public release. |
| Can I filter by sale price or date? | The Actor currently supports filtering by borough only. You can apply price and date filters on the exported dataset using your own analysis tools. |
| Does this include commercial property sales? | Yes. The dataset covers all tax classes, including commercial, residential, industrial, and vacant land. Use the tax class field in your output to separate them. |
| What does the borough code mean? | 1 is Manhattan, 2 is the Bronx, 3 is Brooklyn, 4 is Queens, and 5 is Staten Island. Leave the filter empty to collect sales from all five boroughs. |
| Is there a limit on how many records I can pull? | You can set a maximum of up to one million sales per run. The full dataset typically contains fewer records than that, so setting a high number will return everything available. |
| Does this Actor require an API key or login? | No. It reads the public DOF dataset directly. You do not need to register, authenticate, or obtain an API key. |
| Can I get the data as a spreadsheet? | Yes. You can export your results as CSV or Excel, both of which open directly in spreadsheet applications. |
| What if a sale has missing fields? | Some records in the DOF dataset have blank fields. The Actor returns whatever the source provides; missing values appear as empty cells in your output. |
| Does this include co-op and condo sales? | Yes. Co-op and condo transactions are included and can be identified by their tax class codes in the output. |
