There are 3 major automated valuation model providers in Switzerland: IAZI, Wuest and Pricehubble. We have licensed all 3 models and run them for every single home that is appraised on our website. We then combine the results and apply our own corrections, developed internally with the help and experience of real estate professionals. Examples of corrections include those that are applicable to large areas of land that come with planning permission, laws limiting the price of properties - for instance in the Geneva development zone - and, property/land within agricultural zones, etc.
