My post was somehow deleted, so here it is again
and yes, Bauexperte is right, the waiting time is about 12 months. But then it goes quickly, almost 3 months and you can move in.
So here again is my post from earlier:
With prefabricated houses, a final price can definitely be calculated. But the seller must also want that.
And that's where the problem lies.
Builders want to compare, and unfortunately often look at the bottom right at the total sum. And the one with the cheapest offer gets the contract.
So if the seller wants to sell well, he has to hide/conceal costs so he doesn't always appear as the most expensive.
Unfortunately, in the industry, the honest ones lose out...
We decided on a provider quite early and made that very clear to our seller. The decision was based on some colleagues who built with the same company and on conversations with builders of this company. We roughly knew what to expect with the house.
From that moment on, we could clearly tell our seller what we wanted and keep it fixed in terms of price.
Until the selection of materials, we had a fixed price. The only prices our seller did not inform us about were the trades not described in the construction service.
These were:
about €800 for the base plaster
about €1400 for a KFW pull-down attic ladder
about €1000 for construction electricity
about €500 for the fencing
about €4000 for the redesign of the floor plan (we changed a lot.)
The only unknown was the selection of materials for the house. Here, about €10,000 was added, which we spent on special requests and technical upgrades. About €3000 of this amount was unavoidable because we absolutely wanted a fireplace, and it had to be room-air independent. But in financial distress, you can just skip that kind of thing.
So what I can advise you is to roughly compare the construction services, go into new development areas as Bauexperte said and talk to people, and then bother the sellers. You will quickly notice which seller is trying to provide you with prices and which one is wriggling.
In the end, we got a prefabricated house with KFW 55, living space ventilation with enthalpy exchanger and preheating coil, fireplace stove, soft water system, gas boiler, solar, 300l hot water, gas connection for the kitchen, about 150 sqm living space, base plaster, satellite, and complete Ethernet (CAT7) wiring, 2 bathrooms (ceramics from Renova) completely finished, 5-point locking of the front door + improved burglary protection for roller shutters and windows, about 80 sockets (cost per socket approx. €50, almost 40 were included), clay tiles, painted roof undersides, colored stripes outside on the plaster, entrance canopy, stainless steel standpipes for exactly €223,000. Everything that came around that was our problem. Incidental construction costs were extremely high for us, but the house provider is not responsible for that. That is solely due to the plot of land.
I am sure, if you negotiate well with the seller, you can get the same house for the same price. However, my seller really had to phone the provider quite often in the end to get even more discounts approved.
You have to be a little tough there. After all, it’s a lot of money.
