FEIN for a mortgage: what to check before signing

What the FEIN is and why you should not sign it without reading it

The European Standardised Information Sheet (FEIN) is the document that summarises the essential terms of your mortgage and forms part of the pre-contractual stage designed to strengthen transparency and understanding of the loan. Law 5/2019 explains that its purpose is for the borrower to be able to know the economic and legal burden of the loan before committing, and for the notary afterwards to check that the documentation and deadlines have been properly met. In addition, the FEIN appears in Annex I of the regulation and, under Article 14, must be delivered at least ten calendar days before the contract is signed, as a binding offer for the lender for the agreed period Law 5/2019, preamble and Article 14.

The practical question is not only “what is it”, but “what should I check before signing?”. The answer is simple: everything that affects what you will pay, when you will pay it, what may vary and what conditions bind you.

1. Read the full FEIN before comparing it with what you were told verbally.

2. Note any differences between the commercial offer and the document.

3. Do not sign if there are concepts you do not understand or that are not clearly stated.

4. Ask for any detected error to be corrected in writing.

What to review on costs: do not stop at the monthly payment

The FEIN is not only there to show the monthly instalment. You should look at the total cost and the charges that make up the APR, because that is often where the least visible part of the mortgage lies. Annex I states that the APR is the total cost of the loan expressed as an annual percentage and that it must include the different components of the price, while costs unknown to the lender must be highlighted as such. It also states that, if there is a fee for registering the mortgage, this must be reported in the FEIN itself Law 5/2019, Annex I, Part A and Part B.

Check in particular:

1. The exact amount being lent and the currency.

2. The total amount to be repaid.

3. Which costs are included in the APR and which are not.

4. Whether there are arrangement fees, early repayment charges or other costs for ancillary services.

5. Whether costs not included in the APR are clearly identified.

Practical tip: do not compare only the monthly payment. Two mortgages with the same instalment can have very different costs if the APR, fees or linked services differ.

Common mistake: accepting that “I’ll sort it out later with the notary”. The FEIN is precisely there to be checked before you get to that stage.

What to check about the loan terms and risks

The FEIN must explain whether the interest rate is fixed, variable or mixed, and how it is reviewed. It must also state the payment frequency and number of payments, as well as the amount of each instalment. If the interest is variable, the sheet must warn that the instalment may go up or down and provide illustrative examples. If the loan is in a different currency from yours, it must explain the exchange-rate risk and its possible effects Law 5/2019, Annex I, Part A and Part B.

Review these points carefully:

1. Whether the interest rate is fixed or variable in each period.

2. From when the rate can change and with which reference or formula.

3. Whether there are any caps or floors.

4. Whether the instalment amount is calculated only for the initial period or for the full life of the loan.

5. Whether the loan includes linked products or mandatory ancillary services.

Law 5/2019 also states that pre-contractual information must make it possible to understand the loan’s full economic and legal burden. That means it is not enough to read isolated figures: you need to understand how they relate to each other.

If the FEIN mentions insurance, accounts, cards or other associated products, ask whether they are compulsory in order to obtain the mortgage or whether they only improve your terms. The FEIN itself must state whether the ancillary service can be taken out with a provider other than the lender.

Documentation, deadlines and warning signs before signing

Alongside costs and terms, there is a third essential check: the documentation. The FEIN must be accompanied by a clear, readable and complete structure. Article 9 of the Law requires clear and comprehensible general information on credit agreements, including the duration, forms of borrower rate, possible costs, repayment options and ancillary obligations Law 5/2019, Article 9.

Bear these steps in mind:

1. Check that the FEIN matches the property, amount and term you requested.

2. Review whether the offer is within the stated validity period.

3. Make sure you have also been given the rest of the required pre-contractual documentation.

4. If there is an intermediary, identify who is advising you and how they are paid.

5. Do not sign until any discrepancy has been resolved in writing.

If you are buying a property in Madrid, in addition to the mortgage you should review the legal and financial status of the property. The Community of Madrid recommends checking the title search certificate, the status of IBI payments and community fees, as well as the usual documentation in a property sale Community of Madrid, property sales. That does not replace the mortgage review, but it does help avoid surprises in the overall transaction.

Common mistakes when reviewing a FEIN

These are the most common errors to avoid:

1. Focusing only on the initial instalment and not looking at the total cost.

2. Failing to check whether the interest can change.

3. Overlooking fees or mandatory products.

4. Assuming that everything discussed verbally is reflected in the FEIN.

5. Signing while still unsure about deadlines, terms or documentation.

If you spot a difference between what you were offered and what the FEIN says, ask for clarification before continuing. If the figures, fees or terms do not match, do not treat it as a mere formality: it may directly affect your purchase decision.

The FEIN is not an official valuation or a simple sales brochure. It is the key document for deciding whether the mortgage fits your purchase. If you want to review your case before moving forward, you can request an indicative valuation at /valoracion-vivienda-madrid or write to us via /contacto. Our office is at Calle Montesa 29, Madrid, with opening hours Monday to Friday from 10:00-15:00 and 16:00-19:00.

In short: before signing, check costs, terms, documentation and risks. If something does not add up, ask for corrections or further explanations. The general guidance in this article does not replace individual advice on your specific offer.

The general minimum notice period for the documentation provided for in Law 5/2019 is ten calendar days; it should be checked whether the competent autonomous community requires a longer period. Receiving or signing an acknowledgement of receipt of the FEIN does not amount to formalising the mortgage loan: the deed and the prior notarial advice are different actions.
