Frequently asked questions about Property Valuation Plus for properties

Property Valuation Plus is a service by Comparis that provides you with a detailed and interactive valuation report of your property in Switzerland based on exclusive proprietary Comparis data and open-source data. The report includes the projected market value, local price trends, supply and demand insights, a tranquility index, and more. It is interactive, securely stored in your MyComparis account, and available to you without time limits. You can generate unlimited PDF downloads of your report at any time.

You can use the report to better understand the market value of a property and its surroundings. It helps in preparing for a sale, a purchase, refinancing, or simply gaining a data-based perspective on the property. The report is designed for long-term access and provides valuable insights beyond a simple price estimate.

Property Valuation Plus is not a replacement for individual assessments by an expert, appraiser or estate agent. The result may differ from the actual selling price, as this is also influenced by factors such as negotiating skills, market sentiment and buyer interest.
In addition, the valuation corresponds neither to the collateral value used by banks nor to the official market value. It is based on the assumption that the property contains the standard fittings and appliances and is in an average condition. In the case of luxury properties or properties in need of major renovation, the results may therefore differ significantly from the actual market value.

We forecast the expected market price for apartments and houses using machine learning methods. Carefully selected training and test data from numerous Comparis property listings are used as the basis for these machine learning methods. Our property valuation model is regularly updated with the latest market data. We are currently using version 25.10.v3.

Comparis combines its own extensive property data with carefully selected external sources to provide detailed property valuations.
  • Comparis proprietary data:
    • We use historical and current listings from Comparis as well as anonymised user activities such as search subscriptions and traffic data
  • City classification for the price forecast:
    • For geographical and structural classifications, we rely on the zoning information from the Federal Statistical Office (FSO).

  • Federal Geodata Infrastructure BGDI (swisstopo):

    With the exception of the images, you cannot edit your valuation retrospectively. The information contained in the report corresponds to the property details submitted at the time of purchase. It is not possible to retroactively amend this data. If you wish to take into account updated information, you can request a new valuation at any time.
    If you would like to give your dossier a personal touch, you can optionally upload up to eight of your own images and the floor plan of your property. You can change the images and your cover image at any time.
    If you have any questions or suggestions, please do not hesitate to contact the Comparis property team at valuation.plus@comparis.ch.

    Images will appear in your online dossier and in the PDF document in the order in which you upload them. The first uploaded image will therefore be the cover image of the PDF. You can change the order of the images or swap them around at any time.

    If you have any further questions, our real estate team will be happy to help you at valuation.plus@comparis.ch.
