What is a binding mortgage offer?

Broadly speaking, a binding mortgage offer is a regulatory document of great value for formalizing certain conditions of the mortgage loan. This document meticulously reflects the terms and conditions of a specific mortgage loan that the client and the financial institution have agreed upon.

In other words, it is a legal instrument in which the bank specifies detailed and personalized information about the key characteristics of the offer. By signing, both parties commit to respecting and fulfilling the agreement within the established timeframe.

This highly important document is issued at the precise moment the client expresses their willingness to accept a mortgage loan. The conditions of this offer gather specific information about the property's status and the borrower's financial capacity, among other determining factors.

What detailed information should this specific document include?

Among many other aspects, the binding mortgage offer facilitates the key comparison of conditions and data related to the mortgage loan itself. It is essential that it includes unique, accurate, detailed, and personalized information in writing. The most relevant aspects are the following.

  • Real appraisal value of the property subject to the future transaction. This supports the approved loan.
  • Total loan amount granted by the bank to the user. It must include the exact amount in words and numbers of the loan granted.
  • Loan-to-value ratio linking the loan and the property value.
  • Set interest rate.
  • Fixed term for the full repayment of the loan granted.
  • Amount of the agreed monthly installments or payments, including the actual value of each installment.
  • Miscellaneous expenses and charges. This includes additional payments such as commissions, fees, and taxes.

Differences between the FEIN and the binding offer

Although both terms are binding for the selected bank , they have subtle differences.

  • The European Standardised Information Sheet, better known as FEIN, is the final offer presented by the bank regarding a mortgage. The binding offer is a preliminary document provided to the mortgage applicant.
  • The FEIN Mortgage allows comparing various mortgage offers, while the binding offer shows the formal conditions imposed by the lending bank.

This offer is binding for the financial contracting party, but not for the applicant.

How long is this document valid?

Every financial regulatory document has a stipulated validity period. A binding mortgage offer is no exception. Once the bank delivers the document to the user, they have a 14 business days to accept or decline the offer. If it is not accepted within the established timeframe, it is considered an absolute rejection.

It should be understood that no one is obliged to sign the document as a requirement. If the imposed conditions do not seem acceptable to you, you can make it known.

Can a binding offer be rejected after signing?

When a client receives a binding offer, they are not bound by anything, and are not even obliged to sign it. This document is signed and sealed only by the financial institution; therefore, they are the ones obliged to maintain the conditions.

However, once you go to the notary and formalize the mortgage process, you will be subject to the contractual specifications. If you fail to comply you may incur a breach of contract and be subject to the penalties established by law.

Make sure to thoroughly review what is stipulated in the offer and in the mortgage deed. Both conditions stipulated in the deeds must match perfectly. Remember that this offer is solely to honor the conditions offered by the bank. It will only help you secure better conditions for your well-being.

How long does it take a bank to issue a binding offer?

Previously, approving a mortgage was very simple. The banking sector could present a binding mortgage offer in a matter of days. However, things have changed a bit. Now, inflationary fluctuations and financial uncertainty have made banks take their time.

The period a bank takes to issue these types of offers is longer. Thoroughly examining the financial profile of a potential client can take a couple of weeks. Although there is no legally stipulated time frame yet, it is expected that these offers will be presented within three weeks.

It's worth noting that the time will always depend on the analysis of the sale process, the property's registration verification, the user's financial status, and whether the property has been appraised.
