Good day,
Now my partner and I have an incredible number of questions:
Mhmpf - why didn’t you clarify your questions _before_ you applied for the property?
Who guarantees that? Can it be demanded that this becomes part of the purchase contract? (Without 100mbit upwards I’m professionally ruined)
If the seller does not state it in the notary contract on her own accord: no one. The municipality does not lay the cable, but probably Teledoof does; and how the latter proceeds, heaven knows.
Are there model contracts for unmarried couples regarding ownership allocation based on the monthly installments contributed?
Every couple’s situation is different, ergo must be considered individually. Ask a notary you trust; if applicable, the one who also draws up the notary contracts for the municipality.
The floor area ratio is relatively low at 0.35 and thus corresponds for "our" property to only 160sqm.
It is not low, it is mostly sufficient.
There is not even a finished development plan yet – how can I be sure that I will be allowed to build the house I want?
Not at all. But you can inquire at the municipality in advance about which regulations will presumably be included in the development plan and then hope…
Is it common that the purchase contract on our side may be linked to certain conditions?
Worth a try – more than a "no" can hardly come out of it.
Is there a book or something similar that covers such matters and that you can recommend?
You will hardly have read and understood that by the notary appointment. Ask someone who knows about it. This also has the advantage that questions arising in conversation can be answered immediately ;)
Rhenish greetings
