ah ha.
apart from the numbers not being correct, I consider the income too low to even think about building a house.
Yes, the numbers have already been corrected - about 100,000 more...
I am roughly "all those people" and my house cost half of what the forum community here (rightly) estimated for the planned palace.
I also belong to the others:
First house in the DM era, (at that time DM can roughly be equated with Euro)
50k equity, 50k family loan, bought a semi-detached house, I was just over 30 at the time. That was a good starter used property, and I would do it again today. Plot 250 sqm, carport 150 meters away.
Financing about 250,000€, with 5.5%...
Current house construction (2013): 195,000 plus flooring etc... maybe in total 230,000... the surplus was paid from an inheritance (inheritance unknown at the time of the plot reservation)
Plot: leasehold, deliberately selected because of the missing loan. Age: 45/55, net income 2013: 4,500€, financing amount 207,000€.
