Property purchase / financing in the current situation - yes / no?

I had roughly calculated with 450k debt capital (500k total budget, 50k equity), then 1800€ is just enough. A little more would of course be better. You can also save something or pay down the land loan in the time before construction (definitely finance the land flexibly), which is also counted as equity.

Regarding flexible financing: Our main bank offers a fixed interest rate for land financing from 0.5 up to 4 years. You can, for example, fix it for 2.5 years and then refinance the loan through a new loan from any lender. Isn't that safer than financing variably (then at least we know how much interest we pay into the land)?

The point with variable financing for the plot is that you can terminate a variable financing short-term. If, on the other hand, you commit yourself to the plot for 4 years now, then your bank will be recorded in the land register for that period. However, other banks usually do not enter the land register subordinately, so practically you can then only finance the house with your main bank. The motivation for favorable interest rates is then rather low. Therefore variable, so you have all options open. Alternatively, of course, you can also finance for 2.5 years, but then you are bound regarding the start of your full financing. Many construction companies also require a financing confirmation from the bank before they schedule you. The interest for the plot is the smallest part, so I would remain variable here. If in doubt regarding the interpretation, it is best to inquire in writing with the municipality. My interpretation regarding resale is that the city can effectively choose the buyer (e.g., from the waiting list). The buyer will also have the construction obligation in 3 years as well as the municipality's repurchase right. The costs and taxes will then be paid by the next buyer, not by you anymore.

Then with 2% repayment and 3% interest, that's already more than a 2,000 euro installment.

The question is also, with a 2,000 euro or even higher installment, do you consider that feasible for yourselves (and of course for the bank as well). Of course, that's uncomfortably high. And here in the forum there are also some people who financed not too long ago, paying only around ~1200 per month for the same thing and then tell you "I would never do that, then you're just living for the house!" (seen mentioned in a thread recently quite often). But ultimately, you (and the bank) have to decide whether that still works for you. With your current net income, you still have 3.3k for additional costs and simple living. Currently, your family planning also seems to be more in the area of "maybe someday in 7 years, perhaps." You can definitely calculate a few scenarios for yourselves (or have them calculated) and try to assess the risks for yourselves. We are in a similar situation (currently discussing financing with an installment where I initially wanted to run away screaming). I'm basically a head-thinking person and we've gone through some horror scenarios, but we then concluded for ourselves... actually, we are also mentally quite flexible there. In the worst case, the property is gone and we paid (very) expensive tuition, but even then life goes on. In the vast majority of scenarios we came out thinking "it's not actually that bad." Yes, the "housing" block will initially be larger than we originally anticipated, but we still have potentials in salary etc., and I see that similarly with you for now. But I can also understand anyone who says "no, I just don't want that." Whether you end up better off in the end, you only know afterwards. Sometimes I do get a bit annoyed that we didn't rush into a 110% financing "not that long ago" (haha) but on the other hand, I think if we were in that situation again, I would decide the same way. A lot has happened that was not foreseeable (both privately and in the world). And in that respect, there's no point in fretting, especially because I am currently totally happy with our private situation (not so much with the world situation *cough*). That's also how I see it with the house project. Maybe in 5-10 years I'll look back and think "oh, if only we had waited, we hit the worst time!" or conversely "Thank God we did it then, it got much worse afterwards!" But as long as we don't become unhappy with it, that's actually not so important.

The question is also, with a €2000 payment or even more, do you find that conceivable for yourselves (and of course the bank as well). Of course, that’s an uncomfortably large amount. And here in the forum, there are also some people who financed not too long ago and pay only about ~€1200 per month for the same thing and then say to you "I would never do that, then you only live for the house!" (Recently seen mentioned often in a thread). But ultimately you (and the bank) have to decide whether it’s still doable for you. With your current net income, you would still have €3.3k left for additional costs and regular living. Currently, your family planning also seems to be rather in the area of "sometime maybe in 7 years." You can certainly calculate some scenarios for yourself (or have them calculated) and try to assess the risks for yourselves. We are in a similar situation (currently discussing a financing with a payment that I initially wanted to run away from screaming). I’m basically a head-driven person and we also went through some horror scenarios, but then concluded for ourselves... actually we are quite mentally flexible there as well.

Sometimes I do regret a bit that we didn’t jump into a 110% financing “not long ago” (haha), but on the other hand, I believe if we were in the situation again, I would have decided the same way. A lot has happened that was unpredictable (both privately and in the world). And insofar there’s no point in fretting over it, especially since I’m currently very happy with our private situation (not so much with the world situation *cough*). That’s how I see it with the house project as well. Maybe in 5-10 years I’ll look back and think "oh, if only we had waited, we hit the worst time!" or the other way around "Thank God we did it then, it got even worse afterward!" But as long as we don’t become unhappy with it, that’s actually not so important.

Thank you! That pretty much hits the mark. Over the past months we have repeatedly asked ourselves why we simply didn’t buy something with 110% financing a year ago – but looking back doesn’t help because the situation in construction was not foreseeable for us. Likewise, no one can look into a crystal ball and say what will happen in 3 years. Our bank talks all went in the direction of "it’s still possible, but you have to ask yourself if you really want to pay that monthly" – six months ago it was very different (initially only the two house banks made the idea of ownership attractive to us because they obviously like to finance civil servants). If we had had the commitment for the land already in January, we wouldn’t have hesitated and would have signed already.

We have already dealt with the topic of home savings contracts. However, a home saver, for example over 300k, would never be eligible for allocation within 3 years. We were told that you should put at least 200-250 euros/month per 100k into the home saver – so that would be 600-750 euros/month. And then the home saver (30% of the amount paid in) would only be eligible for allocation after more than 10 years. On top of that come the high contract fees and the fact that you have to repay the home savings loan quickly later in order to get a certain interest rate. That, in turn, would increase the monthly rate.
You can certainly still integrate this into the financing, but for us, an additional 600-750 euros per month for the next 3 years on top of the rate for the land would probably be too much, since we currently pay rent (1,150 euros including utilities/month – although thanks to indexed rent and high utilities, it will probably rise soon). Or do you have a different approach to the topic of home savings?

Doing it fully with home savings makes no sense at all, since by then you will neither be eligible for allocation nor be able to afford the subsequent rate.

Here, a home saver would only make sense if you manage to save about 30-40% when you are supposed to start building, i.e., in 3 years.
That means looking at what lump sum payment you can make now + what you can save monthly.
If necessary, I would even make 2 home savings contracts with 2 different home savings banks:
1x arrange it so that you get a 30,000 EUR loan there (not entered in the land register, thus free, 50,000 EUR home savings sum, must be saved with 20,000 EUR)
1x (if you can save a lot and can make a lump sum payment) the rest, whether it is then 50,000 EUR or more... is still open.

But ideally, it later works out so that you have very good leeway from the bank (loan in relation to construction costs/land value) and thus get a cheaper interest rate.
If you pay 500 EUR contract fee for a 50,000 EUR home savings contract, but then save 0.31% permanently on a 400,000 EUR financing, it amounts to almost 12,000 EUR
(Current interest difference between 95% and 85% financing at ING for 10 years...)

Finally, a worthwhile building savings scheme.
