How much money a Spanish auction needs

The right question is not how much, but in how many instalments

There is no legal minimum for investing in Spanish judicial auctions. What there is instead is a sequence of payments with very precise dates, and whoever enters without that sequence mapped loses money on the calendar rather than on judgement. The 2025 reform tightened the first two instalments, so any calculation you have read that was written before April of that year is out of date.

Instalment 1: the deposit, which now has a floor

To take part in the auction of a property you must first lodge 20 per cent of the value given to the asset under article 666, or a minimum of 1,000 euros where the amount resulting from that percentage would be lower (article 669.1 LEC). The court clerk may raise or lower the percentage given the circumstances, so each auction notice governs.

The deposit is returned if you are not the winning bidder, and forfeited if you win and fail to pay the balance in time. It is not a cost, it is capital locked up at risk. And it locks up your ability to bid elsewhere at the same time: with 40,000 euros and two live deals, each deposit eats into the other.

Instalment 2: the balance, within twenty days

Once the award is approved you have twenty days following the close of the auction to lodge the difference between the deposit and the total price (article 670.1 LEC). Before the reform it was forty. Fail to lodge it and you forfeit the deposit, which is applied to the purposes of the enforcement.

Twenty days is not enough to arrange a mortgage from scratch. In practice that means one of three things: you have the full amount available, you have a credit line already approved and ready to draw, or you are not going to that auction. It is the hardest filter in the process, and it is also what keeps most of the competition out.

Instalment 3: tax, which does not fall because you bought cheap

The purchase is generally taxed under the transfer tax head, a tax ceded to the autonomous regions, so the rate depends on where the property is. We publish none: check the regional rules in force before putting a figure in your spreadsheet.

What is common across Spain is the base it is calculated on. For real property the taxable base is the Cadastre reference value at the date the tax accrues, unless the declared value or the agreed price are higher, in which case the greater of those applies. Put another way: the bigger your discount, the wider the gap between what you pay and what is taxed. Check the reference value on the Cadastre electronic office before you bid.

The municipal capital gains tax, by contrast, runs in the buyer's favour: in transfers for consideration the taxpayer is the transferor, that is the debtor. We develop this in the guide on costs, taxes and charges at auction.

Instalment 4: registry and paperwork, with no notary

Here is a piece of good news almost nobody mentions: you do not need a notarial deed of sale. The registrable title is the certified copy of the award decree, which together with the order cancelling charges goes to the Land Registry. You save the notarial fee of an ordinary purchase.

What you do pay are the Land Registry fees for the entry and for cancelling the subsequent charges, plus an agency if you delegate the paperwork. We give no amounts because they depend on the value of the asset and on the acts registered, but it is a line to reserve, not a footnote.

Instalment 5: what the property drags with it

Whoever is awarded the asset accepts that prior charges or encumbrances survive, if there are any, and assumes the liability arising from them (articles 669.2 and 670.5 LEC). Later entries are cancelled; earlier ones are not. That figure comes from an up to date registry extract and has to be added to the price as if it were part of the price, because it is.

And some debts are not registered and follow the property anyway, such as unpaid homeowners' association fees and taxes levied on the asset on the terms of their own rules. A certificate from the association manager and a check of the council tax position are two calls that change the final number.

Instalment 6: getting possession back

If the property is occupied, between the award and using the asset sits a procedure with its legal fees and, above all, months in which you pay running costs and collect no rent. We do not publish an average timeline because we have no source that measures one rigorously. What you can do is run the deal across several month scenarios. We cover it in the guide on the occupied flat.

The buffer almost nobody budgets

On top of the outlay comes a reserve for when something goes wrong, and at auction something goes wrong often: a charge that surfaces in the updated extract, a levy approved by the association, a repair you could not see from the street because you never got inside. Entering with no margin forces you to sell in a hurry, and selling in a hurry is the fastest way to turn a good purchase price into a bad deal.

How to turn this into your entry figure

1. Start from the auction value in the notice, not from market value or the appraisal.
2. Work out the deposit: 20 per cent of that value, with the 1,000 euro floor.
3. Set your maximum bid and check you can lodge the balance within twenty days with money you already hold or with credit already approved.
4. Add the tax on the Cadastre reference value, not on your bid.
5. Add registry fees, paperwork, the prior charges in the registry extract and the debts that follow the property.
6. Add the cost and the months of recovering possession if there is occupancy.
7. Add the contingency reserve. If the total exceeds what you can tie up without straining, that auction is not yours, however good it looks.

What you do not need

• You do not need to be a professional or a company. Anyone can register on the BOE auction portal with electronic identification and signature and bid.
• You do not need a notary to register the award.
• You do not pay the municipal capital gains tax, which in transfers for consideration falls on the transferor.
• You do not need an intermediary charging you to show you what a public portal already publishes. What takes real work is the analysis of what sits behind each lot.

The mistakes that cost the most

• Budgeting the deposit as if it were the entry cost and discovering the twenty days afterwards.
• Calculating the tax on the winning bid instead of on the Cadastre reference value.
• Bidding in two auctions at once without the cash to settle both.
• Forgetting the prior charges, which are not cancelled by the award.
• Entering with no contingency reserve and being forced to sell in a hurry.

Investing in judicial auctions carries risk: prior charges, occupancy, long timelines and an uncertain recovery value. This guide is informational, reflects the wording in force at the date of update and does not replace professional or tax advice on a specific transaction.
