Building a house without equity?

Just roughly calculate your costs. Here is a reference point:

House €220,000 (for this you get about 130 m2 with standard fittings).
Land €92* your sqm
Property transfer tax 3.5%
Notary fees plus land charge registration (you can find this on the internet)

..and then the often forgotten ancillary construction costs averaging about €25,000-50,000.

If you add everything together, you will probably end up well above the amount you can finance for €1,200.

And since there is no equity, you will also have to cover the kitchen, furnishings, outdoor facilities (very expensive!) etc. with borrowed capital.

Next step: Quickly distance yourself from this crazy idea.

3100 EUR net (forget the KG!) + no EG and then think about ownership???!!! Best regards to Zwegat.

There are simply incomes that are only enough for renting. Especially if you have never saved in your life.

I see that differently in this context. A house up to 260,000 EUR from the 80s or 90s with a repayment of ~900 EUR, maybe 130sqm, then as a monthly burden including additional costs maybe 1250 EUR. With an income of 3100 EUR, that would be about 40% of the income and therefore still okay.

@ ...In our municipality, the price per m² would be 89-92€. Because my wife has already lived there for 15 years, we would also have preferential rights.

Nice, only missing:

30-40K€ incidental building costs
10K€ for painting work
10K€ for the most necessary outdoor facilities
10K€ for carport/prefabricated garage
1500-1600€/m² Energy Saving Ordinance house in standard equipment = 180,000 - 192,000 (only 120sqm)
10-15K€ surcharge KFW 55
10-20K€ for sampling surcharges
+ land (and incidental purchase costs for this)
92€ * 450sqm = 41,450 + 1,500€
+ ~5K notary / mortgage (in your case more than the usual 2%, as the mortgage is far above the land value)
+ 20K buffer for contingencies (such as difficult soil conditions, etc)
+ 20-30K kitchen / etc
=347,000 - 395,000 €

With 2.5% over 30 years, this makes between 1,370 - 1,560€ interest/repayment
+ 300 incidental costs
= 1,670 - 1,860€ monthly burden
+ protection against death of a borrower etc...

Whereas for example the last block with the kitchen is not financed by the bank anyway...

I have to agree with Steffen, I see no room for a home of your own, whether new construction or purchase. My recommendation would be: remain renters. It is cheaper and saves you a lot of stress. In your situation, a new construction would become an extreme burden, including psychologically. For us, the transition from tenant to new build owner, which we are currently going through, is also associated with a lot of stress, I can assure you of that.

Sorry..I expressed myself incorrectly...I meant "income (without equity)"...with a lot of equity, the income can of course be significantly less. Without any equity, however, the income should be very, very high & secure. 6..7..8k net!
