Let's say you "have 400K euros". Land costs 100K euros + additional costs = 110,000 euros. Incidental building costs 30-40,000 euros. Then roughly 250K remains for the house.
VERY realistic and useful guideline values!!!!! Even though the outdoor facilities are missing here. But for around 220-250K you can still build a house of roughly the desired size of the original poster without a basement, even today. I also had no money left for the outdoor facilities, and I am gradually pulling them out of my old discs. Others next door: Ditto, but (almost) do nothing. That actually also takes time, the main thing is that the house is finished and structurally secured. The rest can be done gradually......and with many ideas and effort also a lot of money can be saved. Even if you do something for only 30 minutes every day: It adds up here, unlike owner labor in construction, there is no time pressure.
Now we are entering areas where you have to significantly adjust your demands, put in a lot of owner labor or do magic. :)
That works. Owner labor is overrated. Calculate max. 15-20K, if more then life, zest for life, friendships, marriages,...... break down. You do not need KNX, 150 sockets and so on. Normally equipped: That is already pure luxury. I warn against building with too much owner labor. I myself - to put it fatally - completely crashed and later still did a lot myself, but also had a lot done. Owner labor only works with a huge network of relatives and acquaintances who are willing to help *qualified* almost daily over 7-9 months. Who has that today? The young couple with children? That’s where the stress begins, that can be the beginning of the end of a marriage!!! Don’t do it! I know people who have just moved into a turnkey row house and are gasping on their last leg after 4 weeks of painting and laying floors + moving, and that is only the cherry on top.....the owner labor.
Building is half luxury and I also firmly assume that in 1 year we will have a strong price surge again.
About 60% of people in Germany (approximately) rent. That is not cheap either. Living well, that is always luxury. Living well means: environment, apartment, people, friends, distance to workplace, costs, additional costs etc. are right. There are many people who live well in rental apartments. There are also people - I count myself and my wife among them - who associate traumatic experiences with that. Money is gone anyway, you only live once. Everyone makes that decision for themselves.
And yes: It is getting more and more expensive to build right now. I am already speechless at how prices are rising at the moment.
