Switching your mortgage to a new bank (creditor subrogation): steps and costs

What is mortgage subrogation through a change of creditor?

Creditor subrogation involves changing the holder of the credit rights. The acquiring bank steps into the position of the original bank, becoming the creditor of the mortgage loan under the terms agreed in the new binding offer. The borrower changes neither property nor ownership title; they simply change the creditor to whom they pay their monthly instalments.

It is worth formally distinguishing this procedure from a mortgage novation. A novation is the renegotiation of the contract with the bank where it was originally signed. Subrogation, on the other hand, involves transferring the debt to a competing bank. Key reasons for carrying out a subrogation include:

• Reducing the interest rate: Moving from a variable rate with a high margin to a more competitive fixed or mixed rate to stabilise the household budget.
• Removing tied products: Eliminating the requirement to maintain life or home insurance policies with high premiums, pension plans or other products demanded by the original bank.
• Modifying the repayment term: Extending or shortening the remaining repayment years based on current payment capacity.
• Replacing benchmark rates: Switching highly volatile benchmark indices for more stable references or fixed interest rates.

Steps for switching your mortgage to a new bank

The administrative and legal procedure for switching mortgage providers is governed by strict statutory deadlines and channels laid down by mortgage legislation to protect market transparency.

1. Solvency assessment and market comparison

The process begins by analysing current loan terms (outstanding principal, remaining term, subrogation fee) and comparing them against the market. The new bank assesses the applicant's solvency, stable income and credit history to ensure they meet risk criteria.

2. Issuance of the Binding Offer and the FEIN

Once the new lender approves the operation, it issues the European Standardised Information Sheet (FEIN). This legal document meticulously details all conditions of the new loan: the applicable interest rate, the Annual Percentage Rate (TAE), monthly instalment amounts, applicable fees and specific contract clauses.

3. Notification to the original bank and right of enervation

Following the client's acceptance of the FEIN, the acquiring institution formally notifies the original bank of the intention to subrogate the mortgage via a notary request. The original institution has a legal timeframe of 15 calendar days to issue an exact statement of the outstanding debt.

During those 15 days, the original bank may exercise its right of enervation, submitting a novation offer to match or improve the terms offered by the competitor. Since the enactment of Law 5/2019, the client enjoys complete freedom of choice: even if the original bank matches the offer through enervation, the borrower can decline it and freely complete the switch to the new bank.

4. Property valuation

An official valuation of the property is required. If the borrower provides an approved valuation from an appraisal company accredited by Banco de España conducted within the last six months, the new bank is legally required to accept it without demanding a new report, unless the document's validity has expired.

5. Signing before a notary and registration

Once the enervation period has passed and documentation is verified, the transaction is formalised via a public deed of creditor subrogation before a notary. Subsequently, the administrative agency completes the online cancellation procedures with the former bank and registers the new ownership of the mortgage in the Land Registry.

Costs and expenses associated with switching your mortgage

The distribution of expenses arising from a mortgage subrogation is regulated in Spain by the Real Estate Credit Contracts Law, assigning most of the operational burden to the banking institution taking on the loan.

Expenses covered by the new bank

The acquiring financial institution is legally required to cover the following items:

• Notary fees: Fees resulting from drafting and executing the public deed of subrogation.
• Land Registry fees: Tariff fees generated by registering the change of creditor on the property record.
• Administrative agency fees (gestoría): Processing of files, online filing and management of documentation.
• Stamp Duty (IAJD): Tax exemption for subrogation or tax liability rests with the banking institution under applicable regulations.

Expenses covered by the mortgage holder

The client only needs to pay the following direct costs:

1. Property valuation: The technical cost of the valuation usually ranges between 300 and 500 euros, depending on the property type and location.
2. Subrogation or early repayment fee: If this fee is expressly stated in the initial contract, the outgoing bank may apply it strictly to the outstanding principal being repaid, complying with statutory caps set by Law 5/2019:
   • Variable-rate mortgages: Maximum statutory cap of 0.25% of the repaid principal during the first three years of the contract, or 0.15% during the first five years. From the sixth year onwards, the statutory fee is 0%.
   • Fixed-rate mortgages: Maximum statutory cap of 2.0% of the repaid principal during the first ten years of the loan, and 1.5% from the eleventh year onwards.

Specific considerations in Comunidad de Madrid for Social Housing (VPO)

At regional level in Comunidad de Madrid, subrogating mortgages on properties subject to public protection schemes (VPO, VPPL or VPPB) requires specific checks. If the protected property falls within the legal restriction period on disposal, changing financial terms or creditor requires ensuring that maximum sales prices are not exceeded and that conditions set by the Directorate-General for Housing and Rehabilitation of Comunidad de Madrid are not breached.

If the owner decides to carry out the voluntary disqualification process (descalificación) for protected housing within Comunidad de Madrid to operate in the open market, this administrative procedure must be completed prior to or in coordination with subrogation to avoid conflicts when registering the new mortgage terms in the Land Registry.
