Is this financing feasible?

Wow, there is really a lot going on here

Opinions differ greatly (see Post #9 and #10), but that’s how it should be. It’s meant to be a discussion.
At least no one has thrown their hands up in despair and considered it absolutely impossible.
Starting construction is not urgent, I don’t want to rush such a decision. If the plot is gone by then, so be it.
I also find Grym’s post #11 particularly interesting; I hadn’t directly considered it that way before. It’s of course an interesting and valid approach.
Regarding children, I’ve already witnessed some controversies here. How one’s own situation with children will be, I think is hard to judge in advance, even if you hear quite a bit from your circle of friends, I believe your own situation is something different again. I think we can also hold back on purchases for the child since we’re generally rather frugal. Of course, the things should be reasonable, and when hormones come into play^^... we’ll see.

Thanks so far to everyone who is joining the discussion.

Parents also save money (pub, disco, cinema, restaurant, ...). Well, until the family vacation .

We really saved a lot there too. Instead of one week in New York with a hotel a few blocks from the Empire State Building, it was a holiday home by a lake near Berlin with my sister-in-law and brother-in-law. It was more kid-friendly and much cheaper. We didn't fly with our little one, 1 1/2 years old, yet.

We have the Stuva from Ikea and it works great. We picked it out and received it as a gift. What kind of folding mechanism is that, did I miss something? The changing takes place on top, a used Reer warming lamp was available for 20 EUR (my wife's playfulness, I would have just bought a new one on Amazon for convenience) and it stands next to it. Plus an Angelcare diaper pail for 30 EUR.

The two open compartments in the Stuva got inserts like these; clothes are stored in the lower four drawers, a few supplies are on the middle open shelf, and there is enough space on top to put a diaper angle, for wet wipes, and now I regularly dress the little one there for going outside. Nothing has ever fallen down or caused a dangerous situation. We pay attention when we change, dress, etc.

For stroller, infant car seat, and buggy: Bergsteiger Capri. White, so you are visible at night in winter. Of course, it gets dirty, that’s clear, but safety comes first. And of course it doesn’t look nice anymore, we don’t take care of it, and even a snap button is already broken, but that’s an item for use, not for looking nice. I found the freely rotating front wheels much more important. Friends have a more expensive model with fixed front wheels, and that pushes really badly. Also, the stroller/buggy fits perfectly with two hand grips into an Opel Astra, so no need for a bigger car.

Oh yes, we also received the Bergsteiger as a gift.

We have a rearward-facing child seat from Römer, they normally cost 400 to 500 EUR. We simply bought the previous year's model (new!) for 270 EUR. So basically, also got it as a gift. That was already a Christmas after the Christmas when we received the changing table, little bed, bassinet, and stroller as gifts (each from our parents).

We also received lots of clothes as gifts and bought many cheaply used from acquaintances (e.g. 3 big boxes of mixed clothes for 20 EUR). Second-hand from outside shouldn’t even be necessary, just gifts or used items from the family. Only for "important" things like ergonomically good shoes or the sleeping bag did we have to buy ourselves and of course here and there a few cute items for a few euros...

And yes, there are not many of these allergy children. But in our circle of acquaintances, there are a respectable 3 children. And so many do not have children yet. One should simply keep in mind that the first (I would say) 3 years can potentially become very expensive.

Why allergy children? I think it was rather meant that most breastfeed and therefore do not need powder!?

Why allergy children? I think it was rather meant that most breastfeed and therefore don't need formula powder!?

By allergy children I meant in this context those who, for whatever reason, were not breastfed and reacted very sensitively to most powders. For a completely unexplained reason to me, a large part of these children tolerate the most expensive milk powder on the shelf quite well.

For a reason completely unknown to me

Possibly because the most expensive thing closely resembles mother's milk, which requires considerable effort to produce. But this is becoming very off-topic now ...
