Question 1

Where do seized storage units (trasteros) put up for auction come from?

Accepted Answer

Seized [storage units](/en/subastas-publicas-trasteros) are storage spaces confiscated from individuals or companies for unpaid debts. These can be mortgage debts enforced through the courts, or administrative arrears owed to the [Tax Agency](/en/subastas-hacienda-aeat), local councils or [Social Security](/en/subastas-seguridad-social). Through the [BOE](/en/subastas-boe), these assets are auctioned so the body can recover the money owed.

Question 2

Why is buying a storage unit at public auction a good investment?

Accepted Answer

Investing in seized storage units is ideal due to the low entry cost and high yield. In large urban centres, the lack of space in [apartments](/en/subastas-publicas-viviendas) has driven strong demand for storage unit rental. It is also a very low-risk investment: maintenance costs are minimal, they are easy to resell and there is no risk of illegal occupation (squatters) that affects residential properties.

Question 3

What hidden debts and costs should I check before bidding on a storage unit?

Accepted Answer

Like any real estate asset at auction, the winning bidder purchases the storage unit with "continuation of liens". This means you inherit and must settle prior preferential debts, which for storage units are typically outstanding property tax (IBI) arrears and unpaid Building Community fees. subastAI's AI audits the property registry entry on your behalf to reveal these hidden costs.

Question 4

Can I visit the seized storage unit to check its actual size?

Accepted Answer

As a general rule, it is not possible to physically visit the storage unit before the auction; the asset is acquired under the legal condition of "as is". Since official auction notices sometimes do not clearly state dimensions, subastAI automatically cross-references court data with Cadastre records to confirm the exact square metres of the unit.

Question 5

What is the process for bidding on and winning a storage unit on the BOE?

Accepted Answer

The entire bidding process is conducted electronically. To bid, access the BOE Auction Portal with your digital certificate and make a prior deposit (consignación), usually 5% of the assessed value of the unit. From subastAI's interactive map you can locate storage units in your area, calculate the expected return and access the official lot directly to place your bid.
