The real estate appraisal or real estate valuation is the economic and therefore commercial appraisal of a real estate property (home, premises, building). Is the estimate of the market price of a property at a given time. In order to carry out such a valuation, a predetermined valuation methodology is followed, which is established by law in many countries. The parameters followed to appraise the property must be argued in a report, in order to make the appraisal process as transparent as possible.

Depending on the characteristics of the property, whether it is a house, a flat, a plot of land or an industrial building, the certified professional in charge of carrying out the real estate valuation will be different (they can be architects, surveyors or engineers, among others).
