Feasibility financing new construction (land + semi-detached house or semi-detached half)

What other levers are there?
- Move further away (in the case of Stuttgart, you probably have to go quite far out before it gets cheaper)
- Larger condominium instead of a house?
- Build a smaller house? Possibly with a different contractor? Prefabricated house?

The opportunity with the land is already favorable. What would unsettle me most is the dependence on the landlord regarding the low rent. That probably stifles larger salary increases from the start, since the landlord always holds this trump card?
If this subsidized flat disappears for whatever reason, you would also have a problem renting in the area.

well, moving further away to then commute more?

too much quality of life is lost if you spend 0.5-1h MORE in the car every day. Also, with the current fuel prices, the advantage of saving money is likely to disappear quickly if you then spend 100-200€ more per month (probably 2 cars to also chauffeur the kids)

is that the goal?

I can only agree with here... how often do you get such opportunities
to realize the semi-detached house/end of terrace house with a 200,000€ discount.

inflation in March: 7.3% compared to March 2021
2-3% interest is nothing compared to that.

if inflation stabilizes and remains at 2-3%, then the "real costs" would basically be the repayment... the interest only covers the inflation.

and the tense situation, and if you already have to spend 2,000€ for a comparable apartment now, what does it look like in 5 years? in 10 years?

If you build, you can no longer live in the company apartment anyway. That means you are also no longer tied to your employer.

So if a new job would basically be in prospect, the following approach might be feasible:

- Secure the plot of land. You have 5 years of construction time and could then give it back - at the original price? Then you would have only lost purchase ancillary costs plus interest. Worst case. Study the exit clause in the purchase contract carefully and adjust it to your situation if possible.

- The trickiest point: Find a new better-paid job (man). Clarify the care situation and the woman also looks for a job. Let’s say both earn 1000 euros more, so 2000 plus per month. Horizon 1 year? Pass the probation period and plan meanwhile, move into a transitional apartment. To be able to start immediately, possibly take out a loan from relatives that is then preferably repaid with improved income. For this, you need an intact family who of course should also have the money. I would consider an entry option for the plot in second(!) rank for this loan...

- Town & Country and Danwood I would also have offered to me, both are real prefab providers where currently 300 to 320 TE could suffice for 130 m2 with slab and ancillary costs. Excluding outdoor facilities, painter, floor and garage!

- Omit the cellar or if then only a small partial cellar, about 20 m2 for technology and storage. Nothing else! Minimizes the cost risk with the cellar. Instead of a masonry double garage, only a precast concrete garage or a self-built carport. Outdoor facilities and painter as well as floor work in EL. Provide the attic as usable space, insulate, large folding stairs or proper stairs, have cables routed up. Then later expand in EL.

What confused me a bit in the first post is the statement
"House type? New build terraced house or semi-detached house"

You are building in a community and everyone chooses their house from the catalog and then you want to “stick the houses together”? Sorry, that’s just not possible. Take one of the other three parties as a direct potential neighbor (the one with roughly the same financial potential! Definitely not way above) and clarify roughly what you have in mind: floors, roof shape, location on the plot, size. Be prepared to make compromises here, otherwise it will be more expensive! Then check with the two manufacturers as described above for a semi-detached house and have them offer you something concrete.

I can only agree here with ... how often do you get such opportunities to realize a semi-detached house/ or end-of-terrace house with a €200,000 discount.

My instinct says the same, for many reasons. But I find it hard to put myself in that situation because we have a somewhat different situation, both in terms of income and expenses. It’s easier to talk when you know you can cushion it if something unexpected happens, and it only becomes "a bit more inconvenient." In the case of the OP, the assumptions about the house price (which is probably also sugar-coated by the seller or the construction company), and the relation to income, a financing/construction project here probably stands on such shaky ground that any planning inaccuracies become financial harakiri.

Unfortunately, I see relatively few adjustment options there. Wendlingen is already quite a bit outside, and Allkauf Haus is already a bargain-basement option. The point is simply that the plot of land is way too expensive. With a plot <100k and a house up to a maximum of 300k (construction prices from 2 years ago), all of this would be quite doable. But as it is, the mountain of debt just piles up too high.

I also don’t really see an owner-occupied apartment as realistic. At an estimated 5000€/sqm (if anyone is familiar with the area, please correct me), you end up at 120sqm for 5 people already at 600k. Plus 10% incidental costs that completely eat up your equity.

But what do you suggest instead? They won’t be able to live in the employer-subsidized apartment until retirement, will they? I always thought that in metropolitan areas like Munich (or Stuttgart as well?) it was normal that building a house means piling up debts so high that it’s hardly manageable by one generation? Edit: Sorry for the sentence structure, apparently I had a bag of commas for breakfast this morning.
