Regarding the tools that help you find out what the value of a property might be and what the neighborhood is like, all the information is acquired from the property’s registry information; the Property Registry is the official registry of all property, including housing, commercial premises and lots..
The property prices shown are not the result of an official valuation performed by an industry expert who visits the property to analyze its state of repair and characteristics in order to establish a value. In addition, aspects that modify its value such as a property’s administrative rating (e.g. in the case of social housing), its state of conservation, special characteristics (views, height or beachfront) and facilities (gardens, swimming pool and other services) are not included.
The calculations of property prices and appraisals, as well as the information provided through each of the tools, are estimates. They are solely for informative or guidance purposes, and they do not contain any suggestions, advice or recommendations to apply for a banking product or service. Decisions are made solely and exclusively by the user.
