Strategy for selling a house - what is the best way to proceed?

Our realtor said his commission depends on our selling price?
Doesn't that mean that a higher selling price would also be desirable for him?

That can be a misconception.
Suppose you want to sell for 620k and assume that is a realistic market price. On the second viewing weekend, a prospective buyer offers 600k. The realtor now faces the question of whether to forego almost 1500 euros of taxable commission and make you an attractive offer or conduct further viewings to achieve the appropriate price. For you, however, it would be a loss of 20k euros.
On the other hand, realtors initially try to dazzle you with euro signs during acquisition so that they preferentially get the contract from you. Therefore, the realtor’s estimate does not necessarily have to be below the market price.
That is why you should definitely listen to several realtors and form your own opinion. I have written this somewhere before. We had 5 realtors here, and the estimates differed by 250k. We then oriented ourselves towards the higher estimates, but not the highest.

Good info. And did it work well for you to orient yourselves on the higher estimates? Did you have enough demand? More in urban areas or rather rural? Best regards

It was Berlin, so not comparable in terms of location. What is clear, however, is that real estate agents also have difficulties estimating a reasonable purchase price in these crazy times. Otherwise, it worked well for us, much better than expected.

that I have to accept that potential buyers will find out where my house lives when I sell my property.

... can be significantly limited if the property is not publicly placed on the marketplace.

I always find such claims about how you REALLY achieve the best price somewhat questionable.

From my point of view, this stands and falls - is unfortunately no longer on board here - significantly with the seller’s personal definition of a best price, that is: do I belong to those who are very afraid of the idea that they have not squeezed the maximum out of their personal gold mine chance (then definitely "bidding procedure"), or is the feeling most important to me that the house has been given to other good hands at a fair, value-appropriate price for all involved. Possibly you do not belong to the second type either but primarily enjoy the game of betting whether the market confirms your estimate of an attractive price. THEN you don’t need advice – not mine, nor that of either one of the agents.

Our agent said his commission depends on our sale price? Doesn’t that mean that a higher sale price would also be desirable for him?

Nobody prevents you from arranging with the agent by an additional agreement that his commission at the outcome of 620 will not be lower than at the outcome of 640.

An agent does not necessarily have an interest in achieving the highest possible price, but rather in concluding the sale as quickly and securely as possible. He has no desire for problem cases he has to deal with for months. Therefore, the agent’s valuation will usually be (too) low. You should therefore address rather high expectations (specifically the 630K) in conversations with the agent and see how he reacts.

The interests are as different as the agents: a bad agent likes to have a high-quality property lie longer in his shop window than a dazzling gem because he believes this raises his own shine. A good agent will not damage his market value estimation competence by allowing solvent clients to see him offer properties at crazy prices (but also not at clueless prices). That means: the better the agent, the more he tries to hit the mark with his offers, not missing above or below.

We had 5 agents here and the estimates differed by 250k. We then oriented ourselves on the higher estimates, but not the highest.

As always in statistics: you do not include the extreme outliers in the average. Except if you are the aforementioned gold mine gambler who wants to "log in" the offer of the highest bidder because he sees the jackpot in his property and is only satisfied with the high score. However: in this case, I find a good portion of jackpot awareness quite appropriate.

No one prevents you from putting the broker in a position by means of an additional agreement so that his commission at the result 620 is not lower than at the result 640.

Well then he will surely be highly motivated to strive for the higher price :rolleyes:

I am of the opinion that a real estate agent currently doesn’t have to put in that much effort, similar to craftsmen, general contractors, etc., because the demand is so great. Der Spiegel recently wrote something about the topic of house construction regarding the "boom of botchers." Unfortunately, I can confirm some of that, although I fundamentally have great respect for the craft.
From my own experience, if you advertise privately, you will receive a number of inquiries from agents, even if you forbid it, and they all already have solvent clients........
Anyone looking for a house today has a search order with the common portals or at least checks them regularly. I have mostly seen lousy listings compared to reality and equally lousy buyer visits with agents. The buyer usually has clear questions, which do not interest the agent, so you’re involved anyway.
One difference is when you have to sell something on a difficult market, but as you yourself say, there is nothing even remotely comparable on the market in this region.
Therefore - more or less people will come rushing for your place, since enough people are already waiting for this email with their guns loaded.
Maybe you should simply take a look at what the house would cost NOW plus your fittings, outdoor facilities, etc.
