To achieve the highest possible selling price, you need to get three things right:
Determining the market value realistically
A single estimate is not enough. That is why Bestag combines two independent valuation methods.
We start with two hedonic valuations from IAZI/CIFI and Wüest Partner—the leading valuation models in Switzerland. At the same time, the Bestag algorithm identifies the three agents best suited for your property.
These three agents will view your property and each prepare their own valuation. Together with the two hedonic valuations, you will receive five independent assessments of the market value.
The five valuations are clearly compared side-by-side. They form the basis for the asking price and the subsequent sales process.

Choosing the right agent
With their valuation, the three agents are simultaneously applying for your sales mandate.
During the viewing appointment, each agent presents their marketing strategy and explains how they intend to achieve the highest possible sale price. You will experience all three candidates under identical conditions, allowing you to directly compare their valuations, strategies, and personal presentation.
The agent you choose will later be held accountable to their own valuation. If they sell the property for less than their estimated value, their commission is reduced. This makes unrealistically high valuations, used solely to win the sales mandate, unattractive.
Only then do you award the exclusive sales mandate.

Motivating the agent correctly
The actual marketing begins with the sales mandate. How the agent is compensated influences their behavior.
With the classic commission model, the additional earnings for a higher sales price are comparatively low. With a fixed price, the agent receives the same compensation regardless of the sales price. Both models therefore provide only limited incentives to exhaust the final price potential.
Bestag therefore arranges a performance-based brokerage agreement. The valuation used by the agent to win the sales mandate serves as the benchmark. If they achieve a higher sales price, they receive a bonus. If the sales price remains below that, their compensation is reduced accordingly.
This ensures that both the seller and the agent pursue the same goal throughout the entire sales process: the highest possible selling price.
Bestag negotiates this contract exclusively in your interest – with no upfront payment. Because in the end, what matters is not a lower agent commission, but a higher sales price.

FAQs
Answers to frequently asked questions
What if I decide against selling – do I have any obligations then?
The flat-rate valuation fee has been paid – but you have no further obligations. No brokerage contract, no commission, no penalties. The valuations are yours to keep and will help you make an informed decision.
Will Bestag share my phone number with the real estate agents?
Bestag coordinates the contact with the three selected real estate agents. Your contact details will only be shared with your consent – not with a mass of agents.
Will I start receiving calls from real estate agents as soon as I complete the online valuation?
No. The online valuation on bestag.ch is just the first step. After that, Bestag will contact you—not random real estate agents. Bestag coordinates the introduction to the three selected agents, which only happens once you are ready.
What happens to my data?
Bestag is subject to Swiss data protection law. This website refers to a privacy policy. Your data is used for evaluation and broker selection – it is not sold to third parties.
Can I adjust the selling price myself at any time?
Yes. You determine the asking price and you can adjust it. While your agent may recommend a price adjustment, the final decision is yours. However, a word of caution: don't lower the price in a rush just because you haven't found a buyer after a month. Patience pays off.
Will my neighbors find out that I am selling?
Only when your property is listed on a sales portal – and that is entirely your decision. Everything remains discreet until then.
