Spanish mortgage pre-approval: what it is worth
Quick answer
A pre-approval is a lender’s early indication of what it might lend. It is not the binding offer. The law gives the standard information sheet the force of a binding offer for a period that must be at least ten days. Treat a pre-approval as a guide, not a promise.
Applies toBuyers who want to know how much they can borrow before they look for a home.

§ 1An early indication
Before you find a home, you may ask a lender or an intermediary what it would be willing to lend. The answer is often called a pre-approval. It rests on the income and debts you declare. It is usually not binding, and the lender will check everything again when you apply for a specific home. This page belongs to the chapter in applying for a mortgage in detail.
§ 2The binding offer
The law distinguishes the early indication from the binding offer. The standard information sheet, the FEIN, has the force of a binding offer for a period that must be at least ten days, and the lender must give it to you at least ten calendar days before the signing. If the sheet is valid and you meet its conditions, the lender is bound by its terms during that period.
§ 3What a pre-approval is good for
It gives you a range, so you do not waste time on homes outside it. It shows a seller that you have thought about financing. It lets you find problems with your file early, such as a missing document or a debt. Use it for planning.
§ 4What it is not
It is not a commitment to lend, and it is not tied to a property. The lender’s decision depends on the appraisal of the home you choose, on the legal checks and on its own credit decision. The appraisal in detail explains the appraisal.
§ 5Asking for one
Give accurate information. If you overstate your income, the lender will find out when it checks, and you lose time. Ask what documents it needs, how long the indication is valid and what could change it. Ask for it in writing.
§ 6The contract with the seller
A pre-approval does not protect you if the loan fails. Your lawyer should put a financing condition in the private contract, if you need one, so that you can withdraw without losing the deposit. The legal process section explains private contracts and deposits.
§ 7The timetable
When you find a home, the process described in how long it takes in detail starts. Keep the binding offer’s validity in mind when you choose the signing date.
§ 8Documents
Prepare the documents in mortgage documents in detail before you ask, so that the indication rests on a complete file.
§ 9Pitfalls
Do not pay a fee for a pre-approval from a firm you have not checked. Do not assume a pre-approval will hold when your circumstances change, such as a change of job or a new debt. And do not let a pre-approval push you towards a more expensive home than your budget allows.

FAQRelated questions
Is a pre-approval a guarantee?
No. It is an early indication and the lender can change its mind when it sees your documents and the appraisal. Only the standard information sheet carries the force of a binding offer, and only for the period it states.
How long is the binding offer valid?
Your sheet states its own expiry, and the statute sets a floor on that period. Look at the date printed on yours and fix the signing inside it.
Should I ask for one before I search?
It helps to know the range you can borrow, and sellers may take you more seriously. Ask what the lender needs, and do not pay for an appraisal until you have a specific home.
