Desire to build a house - Is my savings and income enough?

Hello everyone...

I am new here and probably have a really silly question. I am female, single, and would really like to save myself from continuing to put money into rent and would like to have something of my own!! I have the opportunity to build with my sister, her husband + child, or rather we are thinking about doing it together. No plot of land available. My question is, are there semi-detached houses (prefabricated houses) that are divided, for example, 2/3 and 1/3?? Half a house with 100 - 120 square meters would be more than enough for me, I currently live in a 50 square meter apartment. I have a net income of 1600 euros per month, is that feasible?? An ongoing savings contract for a building society currently stands at 13000 euros with 50000 total saved....
Again, I unfortunately have no idea about this area, as our parents also do not own anything and have always lived in rented accommodation. I already thank you for your help =)

Hmm, without a second income in your household, it will be difficult to impossible... with such a low income... You can have anything built you want, but I rather see a house with a granny flat for you... nothing more...

I would also not see a semi-detached house, but rather your own floor. That is financially easier to manage

Yes, there are. But I forgot which prefabricated house manufacturer it was.
Nevertheless, you/you all should rather think about a house with a granny flat... by the way, 120 sqm often isn't even enough for 4-person families ;)
With your salary, 80 sqm should also be enough - rented then from your family.
I would advise against buying a condominium in the family house.

Hello Laufsonne,

basically, you can build anything at first. The crucial question for you is what is right and whether you find a bank that gives you the necessary money, which depends on how high the monthly burden you can bear (comparable to the cold rent) is.

It would be good if less than 40% of your net income had to be paid monthly for financing.

At 1600 €, that would be about 650 €. If we now calculate with an interest rate of 3% and a repayment of 2%, you could finance about 150,000 €.

The question remains whether your dream house can be realized with that.
