What loan amount is realistic for house construction?

My shell construction + roof with double garage (without windows) in Bavaria 150,000, 180m² without basement

180 living area? How big is the garage?

You can't simply calculate the price based on the living area. When buying a car, the number of seats and the exterior color aren't enough for you, are they?

What kind of material (especially masonry)?
What kind of building form (gable, bay window...)?
What kind of windows? Possibly cost-intensive lift/sliding systems?
What kind of roof?
Front door included? What kind?

I want/need rather 300 - max. 350, that works, I have now scheduled an appointment.

As a real estate financier, I have just analyzed your financial situation...

No, you won’t get it.

180 living space? How big is the garage?
