Is a new building realistic?

Since we don’t immediately need the attic studio or rather the space there, we could also save equity by painting and laying flooring there later. The money saved would then be available for the kitchen or other purchases.

When would the start of construction or planned completion be?
Have you already agreed on anything contractual?

But then it would be a bit late to ask about the feasibility...

Some will stone me, and I would never make any financing dependent on that, but the question also arises, could or would parents or relatives temporarily help in an extreme emergency? The question is also open whether something might be inherited someday? Again, I would never ever make financing dependent on that, but if you yourself are 35 and the parents are 70 and they have a house or other larger "assets," then maybe you don't have to be so worried that the house will be paid off by retirement, even if the parents HOPEFULLY live to 100.

Construction will only begin in the fall of this year and completion is scheduled for July 2017. Of the 48 semi-detached houses, about 40 have already been sold and ours would then be the last to be built. The developer has offered us that the financing does not have to be completed immediately but before the start of construction, so we could still take advantage of the new KfW program (up to EUR 100,000 funding for up to 20 years).



My parents unfortunately do not manage money well = no inheritance. With my wife, maybe 1/3 of a detached multi-generation house (190 sqm). One third because she still has two siblings. However, we are not planning on that at all.

Logically, as mentioned, they should preferably live to be at least 100 years old. But if you know that the parents are or would be 100 at their own retirement age and they have a certain "wealth," you might worry less about financing your own retirement age if you are not completely exhausted by then... Especially PSD offers financings with terms of over 45 years.

Construction start is not until autumn this year and completion July 2017.

Then one could still save quite a bit of equity for extras or unforeseen expenses.

And what would the developer gain from that? It surely wouldn't do it out of altruism, would it?
