Auction.com sells homes at auction: foreclosure (trustee) sales, often at a county courthouse, and online sales of bank-owned homes. It has no rentals, price history, tax records or sold comps, so it has no rentals or comps route.

#Location inputs

Auction.com area searches take zip, city with state, county with state, bbox, or lat with lng and radius_mi. There is no neighborhood input.

A city or county is found from its US Census outline, and only homes inside it come back. A misspelled or unknown place returns location_not_served, never homes from somewhere else. We do this because Auction.com's own city and county filters match its stored text exactly, so St. Louis and Saint Louis find different homes.
zip uses Auction.com's own ZIP filter. A few homes are stored with a ZIP+4 code (8 of 1,431 in California in October 2026), and its ZIP filter misses those. Search by city, county or map box to include them.
A radius is searched as the box around it, then cut to the circle.

Home lookups take address, url or source_id. The source_id is the listing number at the end of the home's URL: .../details/2005-n-77th-gln-phoenix-az-2093622 is 2093622. Auction.com lists a home again for each sale, so an address returns the newest listing of that home. Lookups find closed and canceled auctions too.

#Filters

beds_min, baths_min, sqft_min, sqft_max, year_built_min, year_built_max and property_type work as on other sources. property_type takes single_family, condo, townhouse, multi_family, manufactured and land; apartment returns filter_not_supported.

There is no min_price, max_price or price sort. An auction has no asking price, and Auction.com's price filters work on its own value estimate. sort takes newest; without it, the soonest auction comes first.

#Things to know

list_price is always null. The opening bid is in extras.starting_bid. Auction.com publishes most opening bids only shortly before the sale, so it is null on most homes until then. Some online auctions open at $1 with a reserve price you can't see, so the opening bid is not a price.
extras.estimated_value is Auction.com's estimate of the home's value, not ours and not a price.
sold returns auctions that ended in a sale (extras.listing_status_raw is CLOSED). Auctions with no sale and sales still closing are left out. Auction.com keeps only recent results: in October 2026 they went back to December 2025 in Maricopa County.
On sold, online auctions carry the winning bid as sale_price. A buyer's premium may be added on top: extras.buyer_premium on listings and property says when. Trustee sales held in person show no price, so sale_price is null with a field note.
Searches return up to 100 homes per page and say how many match. A city, county, radius, property_type or sold search is cut after it comes back, so a page can have fewer than 100 rows, reported_total is null, and there can still be a next_cursor.
Auction.com gives lot size with no unit: mostly acres rounded to 2 decimals, but not always. It is in extras.lot_size_raw as given, and lot_area_sqft is null.
Auction.com writes 0 beds and 0 baths where it doesn't know them, even on large single-family homes. Those come back null, with a field note.
Rows have the county name but no FIPS code.
estimate returns the value and monthly rent estimates Auction.com shows, with ranges, labeled collateral as Auction.com labels them, and Auction.com's own value estimate (auction_com) when it differs. There is no date for them. We don't make our own.
