Inheritance property - payout to siblings, then construction - financing?

Plan seriously regarding the house costs, transfer the property. Make an agreement with the siblings about when the money should be transferred and then also pay out.

Be sure to ensure that the bank also recognizes this value as equity.

But basically, the suggestion that we should/can build there also came from the siblings, as both know how long we have already been searching and they themselves already own property. The suggestion with the standard land value 2021 (which is 25 EUR higher than 2020) also came from this side, so that no conflict should arise there within the next 12-18 months

Fairly mention that the standard land value does not correspond to the market value, but is indeed significantly (in our case 60-70% higher, Boris) higher. Just because someone makes a suggestion doesn't mean they know what they're doing. What I want to point out is that due to insufficient communication, there can be "justified" and subsequently "enforceable" additional claims that could financially break you during the construction phase. Think about it, something like that is just as popular as a prenuptial agreement but here it’s also about a lot of money.

Hello everyone,

sorry for the late response, but something came up at work.
We are now at the point where we have an appointment with the building authority the week after next. Site inspection, including the civil engineering authority that will give us more details about the costs for the disposal lines. However, we have already been told in advance that we will probably be lucky, since new water pipes also need to be laid in the area and the city will cover these costs (why, as of today, no idea!) - but we would benefit because the remaining pipes would also be laid and we would only have to bear partial costs (definitely less than the initially mentioned 30k).

Regarding land prices: You are completely right that this can normally lead to conflicts - we discussed with the siblings that we wait to see what the city says, what the homebuilders are asking for, and what the bank says about the project.
Then we will know a more precise framework and can discuss the exact payout with them. Basically, though, no one will put obstacles in our way, because if we do not buy the plot, they (provided my SE enjoy a long life!) will see nothing from it, since the SE will sell their house in case of care and buy into a nice residence for that. This is also the general consensus in the family! So at least they would see some money from the approx. 650 sqm ;-)

In the meantime, we also looked a bit for suitable houses and ended up with Viebrockhaus as our first point of contact, since for me as a layman the prices seem realistic and the building specification gives a comprehensive impression!
According to the price list, the houses in question range from 280,000 (Complete V1) to 330,000 (Maxime 300) - due to the higher equipment (photovoltaics, electric shutters, KfW 40+, central ventilation, etc.) we tend more towards Maxime 300.

Do you see the following (complete) rough cost calculation as a basis for initial bank meetings?!
Costs:
House: 330,000 EUR
Plot: 100,000 EUR
Additional costs (groundworks, upgrading [should roughly stay with electrical], floors, authorities): 100,000 EUR (since we would buy directly from the SE, no GES would be payable!)
= 530,000 EUR

Have:
Equity cash assets: 50,000 EUR
"Equity land": 72,250 EUR (long-story short: SE want the development costs to be shared among the three, hence the higher share for us!)
Calculated at 265 EUR/sqm * 650 sqm = 172,250 EUR official land value according to Boris.
Realistic selling price currently on the market certainly at 330-350 EUR (would be "equity land" 127,500 EUR)

Question: What value does a bank take as "equity value"? Boris or its own valuation?

My biggest mental hurdle, where I urgently need a pointer:
Combination of bank loan + KfW + (land) equity

Since I want to go well prepared to the bank, I have already tested one or another financing calculator that also takes KfW into account:
- can I (colloquially speaking) calculate like this?!

Financing need 480,000 EUR
1st rank bank loan: 260,000 EUR
2nd rank KfW 124: 100,000 EUR
2nd rank KfW 261: 120,000 EUR - repayment grant 30,000 EUR

Then there is a finished property with a total value of 650,000 EUR, if I include our "land equity" as security!?
and would thus be at 74% financing!?

As I said, I am currently not getting anywhere mentally with understanding it. Would be very happy for clarification!

Thanks!

Estimated costs by him - pipes 30,000 EUR (approx. 30m connection length), 10,000 EUR "bureaucracy"

Will this now be divided among 3 parties?

Do you see the following (complete) rough cost calculation as a basis for initial bank appointments?!

Items are missing.

Costs:
House: 330,000 EUR
Land: 100,000 EUR
Additional costs (land work, surveying (should roughly stay with electrical), floors, authorities: 100,000 EUR (since we would buy directly from the SE, no GES would have to be paid!)
= 530,000 EUR

Without considering the development, roughly calculated:
Viebrock house 330,000
Floor and painting 20,000 (depends on area and quality)
Upgrades:
Additional construction costs 30,000-50,000
Outdoor facilities 30,000
Kitchen and co from cash funds 30,000

Close but no cigar ;)

Depending on the size, the costs for the outdoor facility can also be taken as x2.
