Question 1

Where do seized houses and apartments come from?

Accepted Answer

[Seized properties](/en/seized-assets) originate from enforcement procedures when the original owner is unable to meet their debt obligations. The vast majority are mortgage foreclosures (bank-owned properties processed through courts or notaries for non-payment), but they also come from administrative seizures for unpaid taxes owed to the [Tax Agency](/en/subastas-hacienda-aeat), [Social Security](/en/subastas-seguridad-social) or local councils.

Question 2

How much can I save by buying a property at auction?

Accepted Answer

Buying seized [properties](/en/subastas-publicas-viviendas) is one of the most profitable real estate investments available, allowing you to acquire assets at discounts of 30–50% below market value. However, the "award price" is not the final cost. To calculate your real saving you must add taxes (such as Transfer Tax, ITP), any refurbishment costs, and outstanding debts on the property. subastAI's AI performs this calculation automatically.

Question 3

What happens if I buy a seized property with debts or squatters?

Accepted Answer

This is the biggest risk in auctions. When you win a property, you also inherit its occupancy status (there may be squatters or contracted tenants) and you are legally obliged to pay all "prior registered liens" (such as existing mortgages or community fee arrears). subastAI's AI audits the lien certificate and court auction notice to reveal these hidden risks before you bid.

Question 4

Can I get a mortgage to pay for an auctioned property?

Accepted Answer

Yes, it is legally possible to finance the purchase of a seized property with a mortgage, but time is your biggest enemy. After winning the auction, the law grants you a very short window (typically 20 or 40 working days for [court auctions](/en/subastas-judiciales)) to pay the remaining balance. If the bank delays approving your mortgage and you miss the deadline, you will forfeit the 5% deposit you paid upfront.

Question 5

How do I search for and bid on seized properties in my city?

Accepted Answer

Although all properties are auctioned through the [BOE](/en/subastas-boe) Electronic Auction Portal, the official search tool does not cross-reference Cadastre data or show real property values. subastAI groups all seized houses, detached homes, penthouses and apartments across Spain on an interactive map. Simply filter by province, review the AI profitability report, and follow the direct link to place your official bid.
