A valuation is only worth something if you understand where it comes from. Here is how our model calculates a price range, what data it draws on and what it does not claim to do.
The price shown in a listing is not the sale price. Between the two lies the negotiation, sometimes several months on the market and often a gap of several per cent. Our model rests first on the sales actually completed, the ones that show what buyers really paid.
We cross-check this data with the price levels observed street by street and neighbourhood by neighbourhood, to place a property in its immediate market rather than in a cantonal average that means nothing at the scale of an address.
The Swiss market has its own rules. Two neighbouring communes can show a thirty per cent gap because of taxation, access to the lake or transport links. Scarcity of supply weighs heavily in urban areas, and an open view carries a price. A generic model misses these effects, ours takes them in.
Each characteristic of the property is weighted according to its real bearing on the local price. Surface area and the number of rooms set the base, location, condition, floor and parking do the rest.
No online valuation can quote a price to the last franc without having seen the property. That is why we hand over a range. Its width reflects the level of uncertainty, tighter when local data is plentiful, wider when comparable sales are scarce.
The more precise the information provided, the tighter the range gets. An exact address, an accurate surface area and a stated renovation condition are worth more than an approximate entry.
An online valuation gives a solid basis for preparing a sale, talking to your bank or weighing up whether to keep or sell. It does not replace the visit of a professional, who alone can judge a hidden defect, a particular character or a nuisance that the data does not capture.
We see the valuation as a reliable, free starting point, not as a verdict. The decision stays in your hands.
