Construction costs are currently skyrocketing

That's why there are so many aphorisms about planning. Man thinks, God directs. If you want to hear the gods laugh, tell them about your plans. No plan survives first contact with the enemy. He who plans errs more precisely. He who plans replaces chance with error.

The bank usually has an interest in not letting the thing fall through... And a lot can have changed in 10 years...

- Partner m/f/d is working full-time again

Two weeks ago, a divorce house from 2021 was online for 4 days... A colleague was the first to view it at 9 - the second appointment bought it without negotiating. It wasn’t a bargain but not outrageous either... Properties are still being sold well...

And when I see that with KFW there is up to 150k for 0.01%, the so-called grandma’s house for 120k purchase in the countryside also becomes interesting because it still stands on 1300sqm instead of 450...

Your first "argument" only counts in good weather phases. When prices come under pressure and the banks themselves too, no one cares about the "no interest in foreclosure." But why should banks already be having problems? And certainly they have not heavily exposed themselves with real estate loans at peak prices that can no longer be achieved in foreclosure.

Properties are simply no longer being "well" sold—the market has collapsed, down 50% year over year in terms of financing. Even Sylt is now being mentioned in the media along with price declines. Whether your mentioned house is "sold" you only know once it doesn’t reappear. The quick bidders still have to go to the bank—interest rates > 4% are currently in effect, and contrary to your assumption, 5% is expected by year-end. Inflation remains high; 3% is far off.

The KFW loan is for new construction, Kfw40+QLN, with €15,000 + appraisal costs. You won’t get that for your grandma’s house. The EU has set the course for the grandma’s house today; it certainly won’t be cheap.

The loan from KfW is for the new construction

Have you taken a look at the KfW page? "261 - Residential Building Loan. Energetically renovate house and apartment" I don't see anything about new construction here?

Well, I assume there was a financing confirmation at the viewing?

There is a loan from KFW for renovation, but not for individual measures, only if a certain KfW standard is reached. We do a lot, but we still definitely won’t reach it. Our insulation dates back to 1993, for example. I already found that steep, because we are still spending several tens of thousands of euros on energy-efficient renovation.

We are currently in talks with the shell builder. The first offer is now about 2 weeks old and after yesterday's conversation, the information came unofficially that he will revise it again because he has received new price lists. As an example, he mentioned the sand-lime brick, where prices have been adjusted downwards by 5%. He said he hasn't experienced this in the last 5-6 years.

We are also noticing a price decline in photovoltaic modules. We have an offer for around 16k with modules for 15 kWp, a storage unit with just under 10 kW, and an inverter. Of course, all this is for self-assembly, together with our electrician, who will also carry out the acceptance.

Interest rates: We finalized our financing about 2 weeks ago. We have now accepted a final interest rate of 3.75%. Naturally still more than last year’s 1-2% interest rates, but not yet 4.5%. However, I have already heard from acquaintances that they were offered 4.3% in northern Germany. We are located in East Westphalia/South Westphalia.

That sounds pretty good already.

3.75% over 10 years?
