Follow-up financing experiences. What has this brought upon you?

Some things simply cannot be foreseen. Additional costs for excavation beyond the normal surcharge for soil class 6 or 7, a shell builder who does not fulfill his contractual obligations, massive price increases for individual trade offers due to the current situation. We had or still have a 20% buffer, but it is currently dissolving into thin air. The main problem is the unfortunate situation with the shell builder: he delayed the construction by 6 months, which means 6 times longer rent, 6 times longer loan commitment interest, relocating excavated soil because it was originally allowed to be stored on the neighboring property and could easily have been refilled, even with a 3-month delay. Now the neighbors needed the property themselves. Terminating the contract with the old shell builder cost us 7k (he threatened to submit addendum after addendum and delay further), the new shell builder thankfully found is 7k above the old shell builder’s offer. Additional rent & loan commitment interest 12k, relocating earth piles 2k. Since the excavation pit has been dug since December, sand has slid in nicely, the ground is softened. Since the excavation pit floor mostly consists of rock, “only” the sand has to be scraped out: 2k - otherwise, there would surely have been an additional 5k to 10k on top of that.
In total 30k, if I have calculated correctly... without even really getting started. The mental strain cannot be monetarily quantified anyway. And we approached this anything but naively. But what can you do when your contractual partner (as a larger, local construction company) just doesn’t give a damn about the contract and simply does nothing.

The only bright spot: the circus with the old shell builder finally ended, the new shell builder is great - in every respect. Really on the ball, honest, pragmatic, and straightforward. A truly honorable craftsman.

As mentioned, additional financing is not yet necessary, but the (ample) cushion is dwindling.

17,000 euros madness
Costs 2.30 euros per sqm for us

Incredibly cheap. Is there really nothing left?! That's madness!

Calculation for us:
600 sqm plot
Redeemption per sqm: 35€
Usage factor: 1.25
Results in approx. 750 sqm x 35€ = approx. 26,000 € development contribution
+ compensation for nature conservation (11€ per sqm) and then the wastewater control shaft

2.30 per square meter has been set by the municipality. It is also stated like that in the purchase contract.

( wir bauen in Schleswig-Holstein)
It seems to me that we still get really fair prices up here in the North.

The total development costs amount to 15-20,000 euros (up to the utility room) plus 85 euros per sqm for the land (905 sqm)

Additional costs for excavation beyond the usual surcharge for soil class 6 or 7, a shell builder who does not fulfill his contractual obligations, massive price increases for individual trades due to the current situation. We had or still have a 20% buffer, but it is currently evaporating. The main problem is bad luck with the shell builder: he delayed the construction by 6 months, meaning 6 times longer rent, 6 times preparation interest, relocating excavation material because it was originally allowed to be stored on the neighboring property and easily could have been refilled even with a 3-month delay. Now the neighbors needed the property themselves. Termination of contract with the old shell builder cost us 7k (he threatened to submit addendums and further delay otherwise), the new shell builder thankfully found is 7k over the old builder’s offer. Additional rent & preparation interest 12k, relocating earth piles 2k. Since the excavation pit has been dug since December, sand has nicely slid in, softening the soil.

The only ray of hope: the clowning around with the old shell builder has finally ended, the new shell builder is great – in every respect. Really sharp, honest, pragmatic, and straightforward. An honorable craftsman after all.

As said, no extra financing needed yet, but the (generous) cushion is shrinking.

Additional rent and 6x preparation interest 12k? How now, how high are your preparation interest rates? If you pay rent, you don’t repay, so this point is not clear to me. Then you let yourselves be extorted by 7k instead of simply banning the company from the site and threatening to claim damages. For your shell builder, the whole thing was a great deal. Offers are usually issued valid until the start of construction, otherwise it is normal procedure for companies to increase the price after the binding period expires. In total, you have thus thrown quite a bit down the drain, and the new (mini) car for the house probably won't be possible in the end.

And the street? Doesn't it cost anything?
