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

Just above the price threshold (probably the most important one for houses of this size at the moment) You might as well ask for more and not scare off more people. I would see it as a guideline for what you actually want and then go slightly above that. So, for example, 535k. Personally, with the information I have, I would probably go for 549k.

I would personally probably go with the info at 549k.

Do you really think there is still demand in a very rural area? 549k would be €3588 / m² of living space. On average, houses as new as ours were sold for 2800 in 2020. That is a 28% premium on the average price from 2020. Is that really achievable?

Well, you live there too. If the market really is as described. And closer to the bigger city with the jobs, everything is even more expensive (or smaller). Then you just need the one person who wants it and can do it, as has been said so many times in this thread, and then it’s not a problem. They don’t think, oh man, this is 28% more expensive than the average of all the other houses sold here, but rather: oh cool, finally a house that’s not too small, not an old wreck in need of renovation or with a two-sided waiting list. Maybe more than I originally wanted to pay, but there’s no alternative and I like the house. I can move in right away – where do I sign?

Oh, and if necessary, if you get the 5th offer under this desired price (and no other), you can still go down. But not with the publicly advertised price.

I would calculate as follows:

Living area x €2,500-3,000
Plot area x sqm price (market price, not BRW)
Plus basement/outbuildings/usable area

I would calculate as follows: Living area x 2,500-3,000€ Plot area x sqm price (market price, not BRW) Plus basement/ancillary buildings/usable area

I initially calculated the same way. I also quickly arrive at values of 540-560k. But that contradicts a multitude of offers from a local real estate agent here, who actually sells reasonably looking houses from the 80s, some of which have been solidly modernized, for 330k. I just can’t imagine that people are willing to pay 200k more just for underfloor heating and the "new build factor"?

One point is how people search. Back then, we set a filter for a maximum of 500k. With that, you would fall through with your prices. However, people with a filter for 600k would definitely take a closer look at your listing, whether 520 or 549k.
