I'll give a small update.
We have now been to the notary and bought my grandmother's house for 325,000 euros.
Ultimately, the financing consists of 3 components:
1st part: 222,500 euros loan from ING at 3.29% interest with a term of 20 years
2nd part: 100,000 euros loan from KfW at 1.97% interest (after the measures end, we can receive up to 25% repayment subsidy)
3rd part: 100,000 euros loan from KfW at 1.97% interest (after the measures end, we can receive up to 25% repayment subsidy)
Equity used - 190,000 euros.
We still have a 40,000 euro buffer.
I will regularly give updates on the core renovation here in this thread.
At the moment we are gutting. This will take a little longer.
The wallpaper was relatively easy to remove. It amounted to 10 bags of 120 liters each.
The suspended wooden ceilings are also down and have already been disposed of.
PVC has been laid throughout the house. It is really tedious to remove.
In the picture here, the PVC is already removed. The substructure at the ceiling is also gone by now.
Under the PVC is a leveling compound that is not even half a centimeter thick.
Under the leveling compound is wood (see next picture)
Here I opened up the wooden floor (which probably lies throughout the whole house) and wanted to look at the screed.
First shock – under the wooden floor there is a layer of sand? that is 7 centimeters thick.

In the last picture you can see the gray leveling compound, then the wooden floor, and beneath a layer of sand.
Can someone tell me if this was common for the construction year (1958) or what the purpose of this sand was?
Next, the entire floor will be torn out and then we will deal with this sand.
