So here I am again. So yes, it's true. The post didn't really cover everything and was written a bit quickly. I don't know if I'll answer everything now, but I'll just start.
Plot: with the usual additional costs for notary and taxes, 125,000 euros, which we pay from equity and we don't want a variable loan in between because we want to save costs. Then nothing is left, but we can quickly put together the kitchen within the year. We live half an hour away from the capital city, so the location is quite attractive, and we were lucky with this plot.
House costs: not final yet because we are still getting offers, but our goal would be 380,000, by the way without a cellar, we just have to do special foundation work which is why we have additional costs here, in the meantime we have been able to deduct 5-10 sqm (before we only estimated, but 160 sqm is actually enough).
So 105,000 are currently calculated by us for all incidental construction costs. I don't think it makes sense to list everything because it varies regionally. But we have gone through the items well and here "only" a carport is included and no landscaper etc. We also have a developed plot in a new development area without slope or major elevation compensation. For example, we will pave ourselves and all this will be done gradually after moving in. Not everything outside has to be finished immediately. If we miscalculate by 5,000-10,000, it wouldn't be bad because we can manage it with ongoing income. We also don't want to take too much credit. That's just a rough guideline. We can't give up much on sqm because we also work from home, but we don't necessarily need a garage and everything outside finished immediately. It shouldn't be calculated nicely, it just shouldn't stress us.
Income and job: Here I only mentioned his income without special payments (we want to reserve those for extra repayments, vacations etc.), our current income is higher but that doesn't say much because I am on parental leave and afterwards I am starting fresh... That's also how the banks calculated it. That's perfectly fine. By the way, no more children after that, so space is planned efficiently. Oh, and you also wanted to know: his job is very crisis-proof, roughly speaking something health-wise would have to happen to him to knock us out.
Free repayment rate change: Our advisor said it worsens the conditions, but I think it's important to be able to decide not only after 10 years, do you see it that way too?
Financing offer: 645,000 for the project, 522,000 loan (where the advisor simply calculated generously, which we will update downwards), of which 120,000 KfW at 0.95% and 402,000 at 1.02% with 20 years fixed interest. That's about 1800 euros per month in total, whereby after 10 years only the one loan with the 20 years fixed interest would remain and repaying 1200 euros monthly would be too little given the residual debt of 172,000 after 20 years. We would want to switch at that point, which according to the offer is only possible once exactly after 10 years. The goal is to be finished after 23 years at the latest. Without special repayments, that would also be the case with 23 years if you assume 1800 euros per month (just roughly calculated the worse interest with the repayment 1800). Special repayments are possible, we want to repay a KfW residual debt of 46,000 euros, which would mean putting aside 4,600 euros each year, quite realistic. Afterwards we would see if we simply continue like that, but of course one also sometimes has a bigger trip in mind. We are not at all attached to the special repayment (it's just a way to get finished faster). And yes, besides the 1800 euros there are still additional house costs. We roughly calculate around 500 euros here.
So, I hope I have described everything more precisely now? If anything is missing, feel free to ask.
I don’t like the loan yet because the flexible repayment rate change is missing and at the moment there is so much new regarding BEG, etc., you have to read enormously. Unfortunately, we missed BAFA, for Baukindergeld we have too much, and waiting for July 1st is not really worth it and would also cause us problems (we want to move in before August 2022).
Now I’ve read that the KfW bonus can only be gotten as a grant and then you would only have to take a loan from the bank?
