Many people certainly exaggerate the amounts here and there. With a bit of restraint in choosing fixtures and house size, a favorable region, and some luck in selecting the plot, you can definitely get the house much cheaper than many here predict. However, it must be said that it is not always easy to stay within the self-imposed budget. Especially in the area of plumbing, it is very hard to overlook the fancy washbasins and specifically choose the standard washbasin, and of course, the standard electrical equipment is often very sparse as well. Whether you really need 5 extra sockets per room or if one additional socket is enough is something everyone must decide for themselves. But these are things that you have control over. Then you notice here and there that some items are missing from the construction service description. If you haven’t looked at that closely beforehand, it can be quite a nasty surprise. For example, none of the construction service descriptions we looked at included a shower enclosure. And then there’s the issue of ancillary building costs, which are very hard to estimate in advance and depend heavily on the plot. Compared to many others here in the forum, we also built small and simple and paid relatively little ancillary building costs and live in the same region as the original poster. Therefore, I can quite well estimate what is doable and what is not. Always relying on no extra costs occurring for ancillary building costs and that everything is included in the construction service description would be fatal. You invest time, visit show houses, draw floor plans, mentally furnish the house, look for the right plot, only to realize that the budget is not sufficient at all. I find it more honest when people get grounded in advance here in the forum rather than being told by the financial broker, "The financing fits."
