How to Buy Property in Spain with a Crypto-Backed Loan Without Selling

Why Borrowing Against Crypto Is Changing How Investors Buy in Spain

Foreign buyers accounted for 15.98% of all home purchases registered in Spain in the second quarter of 2026, according to the Colegio de Registradores. A growing part of that capital is held in digital assets, and its owners face a recurring dilemma: selling bitcoin or ether to fund a property purchase crystallises a taxable gain and ends their market exposure at the same time. Vicox Legal advises international investors on crypto real estate transactions in Spain and Portugal, and the question we increasingly receive is no longer whether crypto can fund a property, but whether it has to be sold at all.

The regulatory context explains why the question matters now. Spain’s MiCA transitional period for crypto-asset service providers ended in July 2026, narrowing the field of providers that can lawfully serve Spanish clients. DAC8 has applied across the EU since 1 January 2026, so crypto platforms report client data to tax authorities. In June 2026, ESMA confirmed that MiCA does not regulate crypto lending as a stand-alone activity, while the European Commission consulted on whether it should.

This guide explains how a crypto-backed loan can finance a Spanish acquisition, which legal and AML requirements apply, how Spanish tax law treats collateral and liquidation, and where the strategy carries risks that a direct sale does not.

What Is a Crypto-Backed Loan for Buying Property?

A crypto-backed property loan is defined as a fiat loan, usually in euros or US dollars, secured by digital assets that the borrower deposits as collateral, whose proceeds are used to pay the purchase price of real estate. The property itself is not mortgaged. The lender’s security sits entirely on the crypto, which it can sell if the loan-to-value ratio breaches an agreed threshold.

Because the lender’s protection depends on a volatile asset, these loans are over-collateralised. Lenders typically advance only a fraction of the collateral’s market value and set two trigger levels: a margin-call threshold, at which the borrower must add collateral or repay part of the loan, and a liquidation threshold, at which the lender sells collateral automatically. The exact percentages vary by provider and are a central negotiating point.

In practice, investors encounter four main structures:

For a Spanish acquisition, the structure matters less for the purchase deed itself, which always settles in euros, than for the AML file, the tax analysis and the risk of losing the collateral. It also differs from the classic route described in our guide on how to buy real estate with crypto, where digital assets are converted to fiat and the conversion itself is the taxable event.

Legal and Regulatory Framework in Spain

Under Spanish law, a property purchase financed with a crypto-backed loan is governed by the same rules as any other acquisition, plus the rules that apply to the loan and to the digital assets used as collateral. Six layers of regulation interact.

Anti-money laundering: Ley 10/2010 and SEPBLAC

Ley 10/2010, de prevención del blanqueo de capitales y de la financiación del terrorismo, designates notaries, registrars, real estate agents, credit institutions and crypto-asset service providers as obligated subjects (sujetos obligados). Each must identify the client, establish the beneficial owner and understand the origin of funds. SEPBLAC, the Executive Service of the Commission for the Prevention of Money Laundering, is the Spanish financial intelligence unit and supervisor. Notaries channel their AML function through the Órgano Centralizado de Prevención (OCP) of the Consejo General del Notariado.

MiCA and the regulatory gap for crypto lending

Regulation (EU) 2023/1114 (MiCA) governs crypto-asset service providers, custody and stablecoins, but it does not regulate lending and borrowing of crypto-assets as a specific service. ESMA confirmed this in a Q&A published on 18 June 2026, while noting that providers who combine lending with MiCA-regulated services remain bound by MiCA’s conduct duties, including prior express consent before client assets are used for lending. The practical consequence is that the lender in a crypto-backed loan may sit outside MiCA, and the investor must assess it accordingly.

Spanish real estate credit law: Ley 5/2019

Ley 5/2019, reguladora de los contratos de crédito inmobiliario, applies not only to mortgage loans but also to professional loans to individuals whose purpose is to acquire or keep ownership rights over land or buildings. Where a lender active in Spain grants such a loan to an individual, the transparency regime may apply, including the European standardised information sheet (FEIN) and the notarial transparency certificate (acta de transparencia). Whether a foreign crypto lender falls within scope depends on how and where it operates, and should be analysed before signing.

DAC8 and the Transfer of Funds Regulation

Directive (EU) 2023/2226 (DAC8) requires crypto-asset service providers to report client transactions to tax authorities, with data collection from 1 January 2026. Regulation (EU) 2023/1113 applies the travel rule to crypto transfers, so originator and beneficiary information accompanies transfers between providers. Both make the collateral trail visible to authorities.

Notarial and registry rules

Spanish notaries must identify the means of payment in the deed of sale (escritura pública), as required by the Notarial Law and the Notarial Regulation, and Article 254 of the Ley Hipotecaria prevents registration where the means of payment have not been identified. Instructions of the Consejo General del Notariado shape how notaries apply these duties and their AML obligations in practice.

Transfer taxes

Real Decreto Legislativo 1/1993 (the ITP-AJD Law) governs transfer tax on second-hand property and stamp duty on notarial documents, with rates set by each autonomous community. New-build acquisitions are subject to VAT under Ley 37/1992 plus stamp duty.

Legal Structure of a Crypto-Backed Property Acquisition

The legal structure of a crypto-backed acquisition involves two separate contracts that must be aligned: the loan and security agreement with the lender, and the purchase contract and deed with the seller. The seller and the notary see only the second; the investor’s protection depends on both.

The loan and security agreement

Most crypto lenders operate outside Spain and contract under foreign law. The agreement determines whether the collateral is held under a pledge-type arrangement, where the borrower remains owner, or under a title-transfer arrangement, where ownership passes to the lender subject to an obligation to return equivalent assets. This distinction drives counterparty risk, insolvency treatment and, potentially, tax analysis. Key clauses to review include the loan-to-value thresholds, notice periods for margin calls, the liquidation method, rehypothecation rights, governing law, jurisdiction and the lender’s obligations on early repayment.

The buyer: individual or company

The purchaser can be the investor personally or a company, typically a Spanish SL or a foreign holding. Corporate acquisitions change the tax profile of the property and the AML file, because the notary must identify the beneficial owner and the lender must lend to, or be guaranteed by, the correct entity. Our analysis of family office property structuring in Spain covers the holding options in detail.

No charge on the Spanish property

Because the security sits on the crypto, no mortgage is registered against the Spanish property. The title registers free of financing charges, which simplifies a later sale or refinancing. Investors can still combine structures, for example a Spanish bank mortgage for part of the price and a crypto-backed loan for the rest, provided both lenders accept the arrangement and the notary can trace each payment.

Step-by-Step Transaction Flow

The process involves seven stages, from verifying the collateral to registering the title. Several run in parallel with the property due diligence.

1. Wallet verification and origin of the collateral — The investor documents how the crypto used as collateral was acquired: exchange statements, on-chain history, tax filings and, where relevant, mining, token sale or business income records. This file serves the lender, the Spanish bank and the notary, and it should be prepared before the property is reserved.
2. AML/KYC validation of the investor — The lender, the receiving Spanish bank and later the notary each run their own identification and risk assessment. Politically exposed persons, complex holding chains and high-risk jurisdictions extend this phase, and inconsistent answers between institutions are a frequent cause of delay.
3. Preparation of legal documentation — Counsel reviews the loan and security agreement, obtains the nota simple from the Land Registry, verifies the property and drafts the arras contract. The arras should include a financing or completion timetable that reflects the loan’s drawdown conditions.
4. Loan drawdown and conversion to euros through a regulated provider — The collateral is transferred to the lender’s custody or protocol and the loan is disbursed. Where proceeds arrive in stablecoins or US dollars, conversion to euros should take place through a MiCA-authorised provider or a bank, and the funds should be transferred to the buyer’s Spanish account with complete records.
5. Notarial execution (escritura pública) — The buyer and seller sign the deed before a Spanish notary, who verifies identity, beneficial ownership and the means of payment, and records the bank transfers in the deed. The notary may request the loan agreement and the collateral origin file.
6. Tax settlement (ITP or VAT + AJD) — The buyer files and pays transfer tax on a resale property, or VAT plus stamp duty on a new build, within the regional deadline, generally 30 working days from the deed. Proof of payment is required for registration.
7. Inscription in the Land Registry — The deed is presented to the Registro de la Propiedad. The registrar checks the deed, the payment identification and tax settlement, and records the buyer as owner, which gives the title protection against third parties.

AML and KYC Compliance for Crypto-Backed Purchases

AML compliance in a crypto-backed purchase is defined by a dual source-of-funds requirement: the investor must explain both where the loan comes from and where the collateral comes from. Documenting the loan alone is not enough, because the loan only exists because of the crypto behind it.

Who carries the obligations

The notary, the Spanish bank receiving the funds, the real estate agent, the lender, if it is an EU-regulated entity, and any crypto-asset provider involved in conversion are all obligated subjects with independent duties. Each must apply customer due diligence, keep records for ten years under Ley 10/2010 and report suspicious transactions to SEPBLAC without delay. Notaries also report systematically through the OCP.

KYC versus AML in a property transaction

KYC (know your customer) refers to identifying who the client is: identity, residence, beneficial ownership and PEP status. AML (anti-money laundering) refers to understanding whether the money is legitimate: source of funds, source of wealth and the economic logic of the operation. A buyer can pass KYC easily and still fail the AML review if the collateral trail is incomplete.

Acceptable and problematic sources of collateral

Cash declarations and the S-1 form

The S-1 declaration applies to physical movements of cash and bearer instruments of €10,000 or more into or out of Spain. It is not normally relevant to a crypto-backed loan, which settles by bank transfer, but it becomes relevant if any part of the funds is carried physically. Spanish law also limits cash payments in transactions involving a professional to €1,000.

Risk of notarial rejection

A notary who cannot reasonably establish the origin of funds or the beneficial owner may decline to authorise the deed. In crypto-backed purchases, the most common triggers are a loan from an unidentifiable or offshore lender with no regulatory status, conversion through a platform not authorised in the EU, and collateral whose history cannot be reconstructed. Our AML compliance guide for crypto real estate in Spain and our analysis of Spanish notary requirements describe the notarial review in more detail.

Tax Implications of a Crypto-Backed Purchase in Spain

Spanish tax law treats a crypto-backed purchase as a fiat acquisition financed with debt. The purchase taxes are identical to those of any other buyer; the difference lies in the timing of the tax on the crypto itself.

Purchase taxes: ITP, VAT and AJD

Second-hand property is subject to Impuesto sobre Transmisiones Patrimoniales (ITP), set regionally. General rates range from 6% in Madrid and 7% in Andalucía to progressive scales in Catalonia, the Valencian Community and the Balearic Islands that rise for higher-value properties. New-build property is subject to 10% VAT for residential use plus regional stamp duty (AJD) on the deed. Since 2022, the tax base cannot be lower than the Catastro reference value. Because no Spanish mortgage is created, there is no mortgage deed and therefore no stamp duty on a mortgage. Our guide to ITP, VAT and IRNR for crypto property buyers sets out the regional detail.

Pledging crypto: generally not a disposal

Under the Spanish Personal Income Tax Law (Ley 35/2006), a capital gain arises when there is a change in the composition of the taxpayer’s assets. Granting a security interest over crypto, without transferring ownership, does not by itself produce that change, and the generally accepted position is that depositing collateral and receiving it back on repayment are not taxable events. Title-transfer and rehypothecation arrangements deserve a specific review, because the contractual terms can affect the analysis.

Liquidation: a taxable transfer

If the lender sells collateral following a margin call or default, the sale is a transfer of the borrower’s crypto. A Spanish-resident borrower realises a gain or loss equal to the sale value minus acquisition cost, applying the FIFO method for homogeneous assets, taxed in the savings base at rates from 19% to 30%. Liquidation therefore brings forward the tax the investor sought to defer, at a moment chosen by the market rather than by the investor.

Interest deductibility

Spanish residents who rent the property out may deduct interest on borrowed capital used to acquire it from rental income, within statutory limits. Interest is not deductible for a main home. Non-residents taxed under IRNR who are resident in the EU or EEA may deduct expenses from rental income, while other non-residents are taxed on gross rental income. Where the property is not rented, non-residents pay IRNR on imputed income, generally 1.1% or 2% of the cadastral value, at 19% for EU/EEA residents and 24% for others, with no deductions.

Wealth tax and the solidarity tax

For Wealth Tax and the Temporary Solidarity Tax on Large Fortunes, debts can reduce the taxable base, subject to rules that, for non-residents, generally limit deductions to debts relating to Spanish assets. The crypto collateral remains part of a resident’s wealth while pledged.

Reporting: Modelo 721, Modelo 720 and DAC8

Spanish residents holding crypto with foreign custodians above €50,000 at year end must file Modelo 721, including collateral held by a foreign lender. Modelo 720 continues to apply to other foreign assets, after the Court of Justice of the EU (Case C-788/19, 27 January 2022) struck down its disproportionate penalty regime and Ley 5/2022 amended it. DAC8 reporting means the authorities will see the transactions regardless.

Taxation in the country of origin and double taxation

Non-resident investors are generally taxed on crypto gains in their country of residence. Whether borrowing against crypto defers tax there depends on local law, and some jurisdictions treat certain lending or collateral arrangements as disposals. Spain’s network of double taxation conventions allocates taxing rights on Spanish rental income and gains on Spanish real estate, which Spain generally retains as the situs state.

Risk Mitigation and Due Diligence

Risk in a crypto-backed acquisition is defined less by the property than by the financing. The investor takes on a liability in fiat secured by a volatile asset, and the main risks arise from that mismatch.

Liquidation and volatility risk

A sharp market fall can trigger margin calls and forced liquidation, often during periods of exchange congestion when adding collateral quickly is difficult. Conservative loan-to-value ratios, reserve collateral held outside the loan and clear notice mechanisms reduce this risk. The investor should model the liquidation price before signing.

Exchange-rate risk between signing and completion

The loan may be denominated in US dollars or stablecoins while the price is in euros. Movements between the arras and completion change the amount available, and a loan in dollars against a euro asset carries continuing currency risk. Drawing down and converting before completion, or borrowing in euros, limits this exposure. The arras contract should set a realistic timetable; our analysis of arras contracts for crypto property transactions covers volatility clauses.

Counterparty and rehypothecation risk

The insolvencies of several crypto lenders in 2022, including Celsius, Voyager and BlockFi, showed that collateral held by a lender that re-uses it can be lost in insolvency. Segregated custody, proof of reserves, regulated custodians and a clear contractual right to return of specific assets are the main safeguards.

Risk of notarial rejection

Funds disbursed by an unidentifiable lender or converted through an unauthorised platform may lead the notary to refuse the deed, leaving the buyer exposed under the arras. Since July 2026, only authorised crypto-asset service providers may operate in Spain under MiCA.

Funds from non-regulated exchanges and mixed structures

Collateral acquired on platforms that never applied KYC, or a mix of crypto loan, Spanish mortgage and personal funds, multiplies the documentation the notary will request. Each source must be traceable independently.

Property due diligence

The financing structure does not change the property review. Before signing arras, the buyer should obtain the nota simple to identify ownership, charges and mortgages; confirm that IBI and community fees are paid; verify the building inspection (ITE or IEE) where required, the energy certificate and, depending on the region, the certificate of occupancy (cédula de habitabilidad); and check urban planning status and any tourist licence restrictions.

Pre-transaction legal advice

Most failed crypto-backed purchases fail on documentation, not on the market. Legal review of the loan agreement, the collateral origin file and the arras before any funds move is the single most effective mitigation.

Sell, Borrow or Combine: Comparing the Three Routes

The choice between selling crypto, borrowing against it, or combining both is defined by three variables: the investor’s tax position, risk tolerance and conviction in the asset.

For investors with large unrealised gains and long-term conviction, borrowing can be efficient. For investors who cannot tolerate a forced sale or who hold most of their wealth in a single asset, a partial sale or a lower loan-to-value ratio is usually more prudent.

Advantages for International Investors

A crypto-backed loan offers international investors specific advantages when acquiring property in Spain, provided the structure is properly documented.

• Tax timing. The investor can acquire the property without realising the gain on the collateral, subject to their country of residence’s rules.
• Retained exposure. The investor keeps their position in the underlying asset during the loan term.
• Clean title. The Spanish property registers without a mortgage, which facilitates a later sale, refinancing or contribution to a holding company.
• Independence from Spanish bank lending criteria. Non-resident buyers often face stricter mortgage conditions in Spain; a crypto-backed loan can bridge or replace that financing.
• Speed in competitive markets. Where the lender is already onboarded and the collateral file is ready, funds can be available within the timeline of a standard arras.
• Planning flexibility. For investors planning to move to Spain, the timing of any crypto disposal can be considered alongside the Beckham regime and residency planning.

Pre-Transaction Checklist for Crypto-Backed Property Buyers in Spain

• Reconstruct the full acquisition history of the crypto you will pledge, with exchange statements and on-chain records.
• Confirm the lender’s legal entity, licences and jurisdiction, and whether it is subject to MiCA or other regulation.
• Verify in the loan agreement whether the collateral is held in segregated custody or can be rehypothecated.
• Calculate the price at which margin calls and liquidation trigger, and keep reserve collateral outside the loan.
• Choose the loan currency deliberately and, if not euros, plan when the conversion will take place.
• Confirm that any conversion to euros will run through a MiCA-authorised provider or a bank.
• Obtain your NIE and open a Spanish bank account that will receive the funds.
• Request the nota simple and check charges, IBI, community fees, building inspection and licences.
• Draft arras with a completion timetable that matches the loan drawdown schedule.
• Assess whether Ley 5/2019 transparency obligations apply to your loan.
• Obtain tax advice on collateral, liquidation and interest in Spain and in your country of residence.
• Share the loan and collateral origin file with the notary before the signing date.
