Can you please tell me why you are coming at me so rudely?
You should provide a few quotes if you are addressing several people in one post, or at least use @, otherwise it gets a bit confusing. Or do you mean me?
Equity consists of equity, land, and personal contributions. If the loan-to-value ratio exceeds 75%-80%, it becomes problematic. Interest rates go up. I estimate by 0.2 to 0.3. Everything has its price. You can also do 100% financing. Then the bank sets the rules.
I can't help you with the financing, as far as I can see you are not the high earners. Try Ikea, they often have 0% financing and there are very nice kitchens with El in assembly for 5000 that are top quality.

If you could also do 75% at the same conditions, borrow 75% and buy the kitchen back from the 5% withheld equity.
Do not mention the word "Küche" to the bank!
