How do you take the interest into account from the purchase of the land until moving in?

Why do you think, apokolok, that Town & Country should not build on a €280,000 plot? Should a cheaper local provider build on it? What do they do better?

Unfortunately, there is partly the opinion here that an expensive plot requires a house that is comparatively expensive in relation.

Complete nonsense, really. If the budget, for example, only allows for €500k and the plot costs €230k, then only €270k remains for the rest. For many, this is an incomprehensible reason to advise against new construction. With this idea, a €500k house fits a €230k plot and an €80k car in the garage is the minimum. In that case, an Opel Astra would be a disaster; what would the neighbors think of you.

For down-to-earth people, a limited budget and an expensive plot simply mean staying more in the basic standard and building a cheaper house. Better than not building at all.

Ok thanks, now I understand. Well, fortunately I am free from such thoughts. Our budget is about 600,000 Euro and I drive a VW from 1995 with over 300,000 km, which I still want to drive for a long time because it's a top car.

It's not about saying that no houses under 500k should be built, but rather that the house price and land price should be in a certain (regionally different) relation to ensure a certain value retention.

If you build a shed on a park-like plot in the city center, to put it bluntly, the probability significantly increases that potential buyers will only want (and pay for) the land upon resale, assigning less value to the house itself.

Following this logic, I align my entire life with eventualities that could occur but don't have to? Could be quite restrictive...

Certainly, but not baseless. Four properties away, someone also installed 5cm insulation under the slab, even though it wasn't required in the calculation. The architect recommended this, precisely because of a potential sale. I also didn't insulate under the slab and left it that way; I'd rather use the +1k € for other things.

Unfortunately, there is sometimes the opinion here that an expensive plot demands a comparatively expensive house.

No one is saying that – this is only a warning against the bait offers on the manufacturers’ websites. Anything else would be grossly negligent...

I do not mean these notes, they are good and necessary. I am referring to opinions like the part of the post I quoted. I often read that here.
