Building with GU: Payment Plan and Guarantees

GmbH & Co KG, correct! Unfortunately, apart from the balance sheet, there are no publications in the Federal Gazette, no profit and loss statement, and no helpful explanations in the text. No idea what inventories are, it only says "Inventories were determined based on an inventory count. Inventories were valued at acquisition or production costs taking into account the lower of cost or market principle."

First of all, don’t rack your brain over the numbers. They are absolutely not meaningful (unfortunately – but this is quite normal for project companies that have no creditworthiness of their own). And the contribution of €400 thousand limited partnership capital can be interpreted however you want. Is the glass half full: The company (the limited partner = usually the GmbH, which is also the general partner GmbH) still has capital available that can be provided. And it is also being done, since the company believes in the future of the project. Is the glass half empty: The bank (which already provides the short-term liabilities) gives the company no further loans. Additional capital, however, is urgently needed since the project is getting out of hand due to increased interest rates, higher costs, and missing customers (who buy the houses/apartments). Both are pure speculation!!!

the limited partner = as a rule the GmbH, which is also the general partner GmbH

The same legal entity being both general partner and limited partner at the same time, I consider that a rumor.

Additional capital is mandatory, however, because the project is getting out of hand due to increased interest rates, higher costs, and missing customers (who buy the houses/apartments).

The OP is building a single-family house; that is not a project business. And I would only take a general contractor who also acts as a building contractor in exceptional cases.

It is often done. Reasons of liability. I see it daily ;-). I have probably written this before under other names, before the adm... got into a fight with me again...

Who knows what is all inside the company. We don’t know any of that. Nevertheless, the equity cushion is more than thin. At least for a contractor. For a property developer / project developer more usual (at least until the time when interest rates exploded).

Willingly done. Liability reasons. I see that daily ;-)

I believe that even less. Then it wouldn't be a KG anymore, I've never heard of a one-man KG.

Small update:
The general contractor has accepted the 10% performance bond until the handover of the house.

An additional warranty bond would cost €500 per year for 5 years.
What do you think about that? I have the feeling that it might not be worth it...

An additional warranty guarantee would cost €500 per year for the 5 years.

Who is supposed to provide it: a bank or an insurance company, in case the general contractor no longer exists?
