The official mortgage appraisal is an essential step in any real estate transaction involving bank financing in Spain. This procedure, regulated by current regulation ECO/805/2003, guarantees that the value of the property being transacted is fair and in line with market conditions. Its importance lies in offering security to both financial institutions and individuals, ensuring that transactions are carried out in a transparent and equitable manner. In addition, an official appraisal is an indispensable requirement for compliance with legal margins in obtaining mortgages and other financial products.

>Whatis the mortgage appraisal?
A mortgage appraisal is a professional valuation of a property, carried out by an appraisal company approved by the Bank of Spain. This report details the market value of the property and is required when a property is used as collateral for a mortgage loan. Spanish regulations, in particular Order ECO/805/2003, require that this type of appraisal be carried out by certified companies to guarantee its validity.
Mortgage appraisals are mandatory in all mortgage financing transactions, as they allow financial institutions to assess the risk associated with the loan. They also ensure that the amount of the loan does not exceed the real value of the property, which protects both the client and the bank.
When is an official mortgage appraisal required?
The official mortgage appraisal is essential in various situations related to the purchase, sale, financing or regularization of real estate. These are some of the main circumstances in which it is required:
Application for a bank mortgage
Banks require an official appraisal to calculate the maximum amount of the mortgage loan they can grant. This value is usually determined based on 80% of the appraised value in the case of primary residences, although this percentage may vary for commercial properties or other uses. The official appraisal ensures that the value of the property is sufficient to support the loan, thus minimizing the risk of non-payment for the financial institution.
Refinancing or mortgage extension
In the process of refinancing or extending an existing mortgage, it is common to request a new appraisal to update the value of the property. This allows adjusting the loan conditions to the current market reality, reflecting possible revaluations or depreciations of the property. An accurate appraisal is key to avoid over-indebtedness or future financial problems.
Purchase and sale of properties with mortgage guarantee
When a real estate transaction is made in which the financing includes a mortgage guarantee, the official appraisal is essential to determine the value of the property. This report provides security to both the buyer and the seller, ensuring that the agreed value is backed by a professional and objective appraisal.
Regularization of real estate
In cases of legalization of properties, updating of cadastral values or registration of real estate in official registries, it is necessary to have an official appraisal. This procedure guarantees that the values reflected in the legal documents correspond to the real market value, facilitating administrative and legal procedures.
Why perform an official mortgage appraisal?
Performing an official appraisal brings numerous benefits for both financial institutions and individuals involved in real estate transactions. These are the main reasons why it is essential:
Guarantee for financial institutions
Banks and lenders need to ensure that the property used as collateral is of sufficient value to support the requested loan. An official appraisal provides this assurance, allowing institutions to minimize risk and establish appropriate financing conditions.
Compliance with legal regulations
Spanish regulations require all official appraisals to be carried out by companies approved by the Bank of Spain. This ensures that the reports comply with legal standards and are accepted by financial institutions.
Applying for mortgages and refinancing
In order for a financial institution to accept a property as mortgage collateral, it requires an approved appraisal in accordance with Order ECO/805/2003. This ensures that the value of the penthouse adequately supports the amount of the loan requested, allowing the bank to finance up to 80% of the value of the property.
Transparency in the purchase and sale of real estate
An official appraisal brings confidence and security to the parties involved in a real estate transaction. Both the buyer and the seller can be sure that the value of the property is supported by a professional report, which facilitates a fair negotiation.
Importance of carrying out the mortgage appraisal with an approved company
Companies approved by the Bank of Spain are the only ones authorized to issue legally valid appraisal reports in Spain. These companies have teams of qualified professionals who apply standardized and regulated methodologies, guaranteeing that the reports issued are accurate and reliable. In addition, the appraisals performed by these companies are accepted by all financial institutions, ensuring that the financing process runs smoothly.
