Property Data for Real Estate Investors
Screening markets, comping deals, or building a buy-box model? Start with the whole dataset instead of scraping listing sites.
What investors need
Investors need price and property attributes at scale — last sold price, beds/baths, square footage, lot size, year built, and current status — across many ZIPs so you can rank markets and comp fast.
Get it in two ways
Bulk download — grab the whole United States or a single state, county, or ZIP as Parquet or CSV, free and CC0. Best for analysis over many properties at once.
Live API — every row carries an id that's a live endpoint on Straply, for one-property lookups and always-current data.
A practical tip
Load a county Parquet into DuckDB and rank ZIPs by median sale price or price-per-square-foot in one query — then pull live status for the shortlist via the API.
