How much should a mid-terrace house cost per square meter today?

I always find such discussions somewhat tedious. What use is it to you if you are given some figure about what the house could currently be worth. In the end, a house (or any other item for sale) always has the value that a potential buyer is willing to pay. Therefore, I wouldn’t worry about a possible value at all, but rather about what you can and want to afford financially and then simply ask the seller directly for a desired price. Otherwise, you won’t get anywhere anyway. If the seller now absolutely wants €500,000 and finds a buyer willing to pay that price, it won’t help you if you know that according to the current market situation the house would be worth about €350,000.

A few years ago I sold a plot of land. The value, according to the standard land value and the asking prices of other plots in the region, was around €70,000–80,000. But the neighboring owner really wanted the plot because he wanted to prevent a development. A house would have cast a big shadow over his garden. So I told him that he could have it for €120,000. It was worth it to him.

Therefore... as a seller you only have to find the person who pays the best price.

From that perspective... as a seller, you just have to find the person who pays the best price.

Yep. That’s what I wanted to say with the 1:4 example above: The current tenant had his own calculation, which was completely irrelevant to me. At the end of the day, I would only grant the current tenant a minimal discount on the purchase price – simply because then no one can refer to any defects of the house, since they had already been living in it for years. I wouldn’t run the risk of being summoned to court because the buyer sues the tenant out and certain agreements are cited (just experienced this recently).

Current tenant pays 590,000 and another interested party pays 600,000? Sorry, but I also have to work hard for 10,000. I’d have to seriously consider whether it’s worth it to me.

If the seller now absolutely wants €500,000 and finds a buyer who is willing to pay that price, it won't help you if you know that the house would be worth about €350,000 according to the current market situation.

If the seller now absolutely wants €500,000 but has no buyer for it, it does help to know what the house would roughly be worth, or to have researched the market. Because then you have better arguments for negotiation than just saying "I can't/won't pay that much." I would scour the real estate market for comparable properties and also observe whether they sell. You can wish for a lot, price-wise, but that doesn’t mean a house is worth that. What interests you are the "sold" ones, but that's harder to find out on real estate sites than on eBay. There is also a document from the committees, I forgot what it's called, but someone here in the forum surely knows. Where you can see the average prices at which houses were sold in a region X, and their year of construction, etc. But only the most recent would be interesting, since the real estate landscape has changed a lot.

Think about what the landlord's motives might be: has she become a retiree and wants to move to La Gomera without a German house holding her back / hike through Tibet, move to her lover in Düss..., or what is it about with her?

I want to bring this up again.

When I remember my land sale: I wanted amount X, the tenant researched a lot and told me that because of the market situation and condition and blah blah, it was only worth X/2.

SO WHAT?

I wanted X, he only offered me half. And he stuck to it, for reasons surely understandable to him. We don't come together. End of story. Keep renting or not, then another tenant will move in.

Another potential buyer had a completely different approach to valuation and paid 2X. Also here: I don't care at all how he calculates it. And he made a huge profit afterwards. His job.

That’s exactly what the cited research is useful for. If I have already done three house viewings in southern Italy and finally want to buy my retirement home there, then I have little time & desire for realtor nonsense and negotiations and co., I want an acceptable price and then get out of here as quickly as possible.

In the case of my above land sale it was rather like "Hey tenant, you can stay on rent or buy it, I don’t care." The final sale was two years later.

You can calculate back and forth how much credit you can afford, but I, just like @kati1337, would never name my price before the seller does.

And all the others who wait first for the purchase price expectation from the other party. I consider that tactically wrong in negotiations. I have already explained this somewhere here before, but I am too lazy to look for it right now. There are several advantages to stating your own expectation first. It sets an anchor (for both sides), it makes completely incompatible expectations clear from the beginning, and you are less likely to overextend yourself. In fact, the likelihood that the deal falls through is higher, but the likelihood is also higher that you end up closer to your own expectations than to those of the other party. I cannot say anything about the specific price because I am not familiar enough with the area. However, I notice in my area that rented properties almost always have a discount compared to unrented properties.
