Official Valuation

The Official Valuation is a report, carried out by an expert valuation technician, which reflects the most relevant aspects of a property, among others, its value.

La Tasación Oficial es un informe, realizado por un técnico experto en valoraciones, que refleja los aspectos más relevantes de un inmueble, entre otros, su valor.

The appraisal report is normally accompanied by an appraisal certificate, which is a summary of the basic aspects of the report.

When is it necessary?

The official valuation of a property is necessary whenever it is necessary to know the real and objective value of a real estate asset.

The most common cases are as follows:

  • When a mortgage is to be taken out or extended.

  • In some cases of novation or subrogation of the mortgage.

  • When you want to use a property or real estate as collateral.

  • In case of seizure of the dwelling.

  • Inheritance distribution, divorces.

  • Valuation for the sale of the property, etc.

Purpose of the valuation

The purpose of the valuation is determined by the client and is subject to the regulatory framework in force. The purpose of the valuation is what defines the focus of the work to be carried out subsequently, the valuation methodology and, consequently, the applicable regulations.

In the case of a dwelling, the required documentation is as follows:

  • Cadastral documentation.

  • In the case of VPO, a photocopy of the definitive qualification certificate will also be required.
