Diario de Subastas

Spain runs its auctions through a state portal, a set of regional and municipal channels and a layer of private auction houses, and no single one of them carries everything. Diario de Subastas aggregates across that fragmentation — its own figures are more than five thousand live auctions drawn from over fourteen public and private portals, refreshed daily.

What you can buy

• Property — the largest category, from homes to commercial units.
• Vehicles, including classic cars and motorcycles through partner sales.
• High-end watches, in their own section.
• Movable business assets and production units.

How the bidding works

The site is a finder rather than a bidding floor: you search by asset type and subtype, then follow the listing through to whichever portal is running that sale, where registration and the deposit are handled. Registration on the aggregator itself is free and unlocks the full set of listings.

What to check before you bid

The authority is always the source portal — a Spanish judicial sale on the BOE portal has statutory deadlines and a deposit requirement that the aggregator's summary does not replace. Check the round and the reserve at source, and check whether a property is occupied before you commit, because in Spain that is the difference between an asset and a lawsuit. The site is in Spanish.
