Home financing with a low salary?!

You write about Passive House - it is not clear to me whether this can be achieved completely without more or less costly technology (controlled residential ventilation, photovoltaics, solar thermal, possibly pellets or heat pump) - I also do not know whether one does not enter other price ranges there with windows, perimeter insulation, wall construction. How big should the house be? Do both have permanent employment contracts?

A Scanhaus Marlow Marlow. 120,000 are turnkey for 4 rooms 120sqm at Scanhaus Marlow Marlow. Then only wallpaper and flooring have to be added. 90,000 if we do the bathrooms ourselves, do the fireplace alone, of course the flooring, and install non-load-bearing walls ourselves. The walls are insulated, windows triple glazed, with water-guided fireplace including underfloor heating. (I think that's the term, that's my friend's specialty, I have no idea about it )

However, we get a few percent off because my uncle works there but not much. Is it only this cheap up here with us?!

I am already amazed at the outrageous prices for land and houses here. It's crazy what some people spend.
Well, if one income falls away, we draw on reserves. It's no different than if an income falls away now. My landlord also wants his money monthly + electricity and insurance. And we already had the case that I was out for 3/4 of a year. However, I have insurance that tops up my sick pay to net salary from the employer DRK.
We have reserves but no equity of tens of thousands of euros.

Yes, we both have permanent contracts, started in the companies after our training.

Well, financing is probably not necessarily the big problem. If a salary temporarily disappears, there might even be housing allowance or a burden subsidy. The problem will more likely be the house price.

What do you mean by that?

With a household income of 2,500 euros, I consider building to be risky. People with different incomes are being warned here.

Yes, I have read that, but they also build houses for 250,000 and the plots cost 100€/sqm.
