What is a sustainable appraisal?

Until now, a property appraisal report reflected the current value of a home and was a requirement to request a loan or know its market value. At Valmesa we have developed the Sustainable Appraisal that also allows you to calculate how much you can increase the value of your house if you transform it into an efficient home.

To estimate the new value of TASOS, an official appraisal* is carried out that reflects the current value of the home and an energy certification where various improvements applicable to the property are studied.

    At Valmesa we estimate the increase in the value of the home after an energy renovation based on several factors: the investment made, the savings that we will achieve with that investment during the useful life of the improvement, the type of home, the visibility of the measure adopted in terms of aesthetic improvement that it can provide and the local market where the property is located. For all these reasons, the increase in the value of the home will depend not only on the improvement made, but also on the characteristics of the valued home and its location.


    It is not a fixed percentage, nor an increase associated with the cost of the reform; To obtain a reliable result, we carry out an in-depth study of the improvement and of the home itself to obtain the new value.
