House construction with 60k equity feasible?

The 60 TE are just the acquisition incidental costs and kitchen. That means you are doing a 100% financing.

At 3% repayment (around 30 years term, 20 years fixed rate, currently 1.3% interest in the best case) that is about 2500 euros per month to the bank cold, you currently have about 800 rent, that means 1700 more plus somewhat higher incidental costs (about 100 to 200 more) plus 100 to 200 euros cash reserve for repairs to save up. So that makes 2000 euros more than you have spent every month on housing so far. Since your balance is 4100 euros, this is doable from that perspective, a bank will probably be found for that.

But: with the supposed 4100 euros surplus, how come you have only saved 60 TE so far? Did you just recently advance professionally or is the calculation wrong because there are no reserves included for car, expensive vacations, etc.? Where has the money seeped away so far, are the 4100 euros realistic?

And very important: how and where would you get a plot of land? That will be the crunch point in the Hamburg area, even more than finding a bank.

Hello, the income is far too low for new construction in Hamburg. You can already see that from the equity of 60k

1.3% at 100% financing? More like 1.7-2%. We get 1.1% effective at 77.5% financing. And I now have 4 financial advisors looking for the best loan

Hello
It all depends on the price of the land. And how far the family is willing to move away from Hamburg.
