1. How the rating process works
The Comparis Rating provides an assessment of a listed rental or purchase price to help prospective tenants or buyers better estimate the attractiveness of the deal.
Benchmark price and savings potential
comparis.ch calculates the benchmark price for the listings. This reflects the average price for similar properties with the same postcode that have been advertised online. The benchmark prices calculated by comparis.ch are based on an average apartment and may therefore vary considerably depending on the property’s condition and standard of fixtures and fittings.
The savings potential indicates how much lower the rental or purchase price of the listed property is compared to its benchmark price.
Comparis Rating
The Comparis Rating evaluates the attractiveness of a property's price compared to the average benchmark price. It is measured using the grading system used in Swiss schools. If the rental or purchase price of a property matches the benchmark price, the listing is given the rating 4.5 (satisfactory). The cheaper the asking price compared to the benchmark price, the better the Comparis Rating.
| Rating of 5.5 - 6.0: | Very good (the property is very cheap in comparison) |
| Rating of 5.0 - 5.4: | Good (the property is fairly cheap in comparison) |
| Rating of 4.5 - 4.9: | Satisfactory (the property matches the benchmark price) |
| Rating of 4.0 - 4.4: | Adequate (the property is fairly expensive in comparison) |
| Rating of 1.0 - 3.9: | Poor (the property is very expensive in comparison) |
2. Method
To evaluate and estimate property prices, Comparis has teamed up with Pricehubble, a leading expert in online home valuation.
The Comparis Rating rates the competitiveness of a property's asking price compared to the estimated market price. It provides a starting point for estimating the value of a home and should not replace a professional appraisal.
Prices are estimated using a machine learning model that produces a best estimate based on past transactions pertaining to similar properties. A transaction in this sense is the successful sale or rental of a property. Criteria such as address, micro-location, property type, size, living space, number of bathrooms, parking spaces/garages, and age of the property influence the calculation and the comparison with similar historic transactions.
The number of similar historic transactions, in turn, influences the accuracy of the price estimate. If the amount of data on the property or the number of comparable historic transactions is insufficient, the price cannot be estimated.
The market price corresponds to the average price of comparable properties in the same residential area according to Internet data. It is based on a property in an average location with an average standard of construction.
Rating discrepancies may occur in the following circumstances:
- The information in the listing is incorrect or incomplete.
- The property is of an above-average standard of construction.
- The property is in an above-average location.
