KfW financing - roughly estimated the following scenario

Hi house builders.

The more I read, the more confused I get, so I'm just asking out loud.
Is the following rough scenario somewhat correctly thought through?

Expenses:
40,000 acquisition costs
Plot 600 sqm 100,000
Kampa/Bien Zemker etc. 40+ house with 260,000

That makes a total of about 400,000

Then the subsidies come back due to 40+
124 1% interest for 50,000
153 1.66% at 100,000 with 15,000 subsidy
431 4,000
270 1.26% for the photovoltaic expansion (so that it really becomes a plus-energy house)
275 1.1% for energy storage and unknown repayment subsidy

Please give me some input so I can get back on the right track.

Best regards
Steve

In your 1st thread you spoke of 30 years; most of your KFW components either only have 5Y fixed interest (the 124); or the term max 10Y

And what the bank does to bundle that into a round package is something completely different. Ever been to a bank to get a first idea?

And then your cost calculation somehow looks like it was rolled randomly.

There is the land + additional purchase costs, then the house + upgrade, then the so-called incidental building costs (i.e. earthworks, supply and disposal connections, etc), garage/carport, garden/outdoor facilities and last but not least a large buffer.

Depending on the degree of completion, usually wall and floor coverings, lamps, kitchen and whatever else comes to mind are added.

I think all-in with that land price you are more likely at 600K and a 40+ house

But you write so little info; one can only guess

Thank you for your patience. We are still very much at the beginning. I simply still have far too little knowledge to really contribute here.

Here you are really mixing up a lot.

1. Nominal interest rate and effective interest rate.
=> You will pay the nominal interest rate.
=> The effective interest rate includes things like land register costs, RLV, etc. You also included the subsidies in your effective interest rates. However, this is only partially correct, namely only to make interest rates comparable. You will still pay the nominal interest rate.

2. Interest rate lock-in and loan term are two completely different things.

If you want to use KfW loans and it looks like you do, then please take another good look. Choose an interest rate lock-in and a corresponding term that you can justify.

3. The subsidy for 153 is not paid out to you, but your loan is reduced. The rate therefore remains the same. You only get the 431 if you have commissioned the energy consultant yourself via an offer. And that only up to €4000, or 50% of the costs of an energy consultant.

4. I cannot assess 270 and 275. But otherwise, all the interest rates you listed here are "wrong". After your new research, please post here again. Please use the nominal interest rate here.

Oh, how nice it would be if you could simply put together a house from the catalog or internet. With fixed prices. Then choose the financing, subsidies are automatically deducted. And in the end, you have an exact price.

Sure. Why bother dealing with something that fundamentally affects the rest of one's life. Better to click-click and order something from the Amazon than to reasonably engage with the matter. Much more convenient that way.
