Defensive offer, or have house prices become so expensive?

I’m not exactly sure what we’re talking about yet, I’m eagerly waiting for the family to send me photos of the property over the weekend. They haven’t gotten around to it yet, and on the day they wanted to leave, it poured rain.
They probably don’t have a hose level, I also don’t know if they feel confident using one. But it would probably be good.
Following a tip here in the forum, I checked GIS Rhineland-Palatinate. But I either can’t find my way around at all, or there are no data. At least apart from the plot numbers, I haven’t found anything that would allow me to infer terrain heights.

Photos are not always helpful for assessing a hillside property. You really need a few elevation points later on to avoid any nasty surprises. If the geoportal doesn't provide sufficient data, you can simply call a local surveyor. They usually have a professional access or know the right sources to get this data. In our case, they kindly did it just like that, but even if you pay for it, it’s money well spent. Attached is our example.

If a hillside property offers a great view, it’s of course worth a premium in the construction (because of the premium, the plots themselves are usually cheaper than flat plots, so it balances out a bit). However, you should consider the added value of such a property for yourself. For example, we were offered a great existing house on a great hillside in a great location... unfortunately, the view was (also) of an industrial area. We then declined politely.

Ha! This Excel sheet already exists! :D At least something similar. I have an Excel called "Kassensturz" where I always enter the most common scenarios. Of course, I base it heavily on my known values from Construction Project I. Only the house prices and earthworks are now very variable costs.

I've attached it for you, feel free to give feedback if anyone sees something unrealistic. The 400k house price is based on the conversation with our currently favored company. The second contender is estimated to be priced similarly, we will talk to them again.

Thanks, that builds confidence. :) ♥ But tell that "not needed" to my wooden staircase. My child has the tendency to throw wooden toys out of his room when he gets bored. :rolleyes:

Looks pretty okay. For the connections, did you base the costs on your federal state or already take the costs from the state where you are building? Because that can vary a lot. For us alone, the water/sewage connection costs about €10,000 :cool:

The basis of their planning is always that the plot of land is fixed. She said it makes no sense before that. Then you would need a soil survey and based on the results you could plan exactly how to place the house on it, including split level and accordingly the floor plan, and how to secure everything. Therefore, she said without a fixed plot of land you can hardly really get started and accordingly also can’t make a well-founded statement about an offer.

Hopefully, I'll get some photos of the property over the weekend.
Thanks for the tip about the geoportal. Unfortunately, I couldn't find anything there at all. If the property looks okay from the photos, I think I will also contact a surveyor. Or rather, at a certain point, we will just have to decide to buy it.
The construction company from today (our current favorite) said that the basis of their planning is always that the property is confirmed. She said it makes no sense before that. Then you would need a soil report, and based on the results, you could plan exactly how to place the house on it, including split-level and accordingly the floor plan, and how to secure everything. Therefore, she said that without a confirmed property, you can hardly really get started and accordingly cannot make a well-founded statement about an offer.
Of course, this is not what someone building a house in full anticipation wants to hear, but I have to say that it is the most serious thing I have heard so far.
