United States Guides How to Download Property Data (CSV & Parquet)

How to Download Property Data (CSV & Parquet)

Getting property data used to mean scraping county websites or signing an enterprise contract. Here's how to just download it — free, in three steps.

Step 1 — Pick your area

You can download the entire United States in one file, or narrow to a state, county, or ZIP code. Smaller areas mean smaller files — a single ZIP is a few megabytes; the whole country is tens of gigabytes. Browse by state and drill down to the area you need.

Step 2 — Choose a format

  • Parquet — the complete file, including nested price_history and tax_history. Columnar and compressed, so it's smaller and fast to query. Best for analysis in pandas, DuckDB, Polars or Spark.
  • CSV — a flat table (no history columns) that opens in Excel, Google Sheets, or any tool. Best for a quick look or non-technical use.

Full field list is in the data dictionary. Everything is CC0 — free for any use.

Step 3 — Open it

Parquet reads in one line most places:

import pandas as pd
df = pd.read_parquet("realestatedataset-florida-2026-07-23.parquet")
print(df.shape)

Or query it directly with DuckDB — no load step, no database:

SELECT city, beds, last_sold_price
FROM 'realestatedataset-florida-2026-07-23.parquet'
WHERE beds >= 3 AND status = 'active';

CSV opens anywhere, including a spreadsheet.

Keeping it fresh

A downloaded file is a snapshot — accurate the day it was compiled (the date is in the filename) and slowly aging after that. If you need current data, or you'd rather query one property than host the whole file, every row's id is a live endpoint on Straply's API. Same records, always fresh.

Frequently asked

How do I download property data for free?

Pick a state, county, or ZIP on RealEstateDataset.com and click the Parquet or CSV download. No sign-up, no cost — everything is released under CC0.

Can I download property records by ZIP code?

Yes. Every ZIP code has its own downloadable file, as does every county and state, plus a single file for the entire United States.

What format is the property data in?

Two formats: Parquet (the full schema, including nested price and tax history) and CSV (a flat table that opens in any spreadsheet).

How do I open a Parquet file?

Parquet reads natively in pandas (pd.read_parquet), DuckDB, Polars, and Spark. It's a standard columnar format supported by most analytics tools.
