New construction - What is included in our financial budget?

no one else has to know where the money went.
Here, it's always the big moralists who think that hoarding money is a superior human trait. You don't have to justify yourself.

I think a 1000€ installment should be doable for you.

Moralists, but also envy-ridden people, who objectively cannot offer any help because they either feel bad when others supposedly have it better since they possess something bigger or newer than themselves and might even be willing to exercise restraint for that, or are simply ready to take greater life risks, or who see the negative in many things without considering that there are indeed people who think not in problems but in solutions and will therefore always find them for themselves.

But I also think that some people don't even own property themselves, yet here they are busily judging as if they do.

Not everyone is like that by far, and quite a few declare their opinion as just their opinion and substantiate it well, so that an important opposing opinion is also present as or for a controversy.

The question is what you get for 1000€ in the region for a property. On the topic of equity, no moralists but realists. If one wants to sell the OP a Hanseatic installment loan as equity again, one is neither the one nor the other but a fraud.

Phew, wild discussion. First of all, with that income and two children, banks set a subsistence allowance between €1,400 and €1,800. This is usually less than what is actually "spent." Thus, between €2,200 and €2,600 remain for financing and incidental costs or extras like vacation, car, etc. With current construction prices and the fact that there is no equity (I’ll disregard the €8k in the home savings contract, as they are often used for purchase incidental costs, etc.), financing is of course possible, but a) expensive due to full financing and b) only enough for a small house. You should be aware of that. For a €300k house (+ €22k for the land) and additional expenses for garden, possibly furniture, kitchen, "small stuff," you have to finance over €300k and will use up the child construction grant over time without actually entering into special repayments. At least, that’s what the majority of home builders do (I can confirm this from professional experience). With a 25-year fixed interest rate and term, you are looking at over 2% interest and a rate of about €1,400. Whether you can and want to do that, you have to decide.

The question is what you get for 1000€ in the region for a property. Regarding equity, no moralists but realists. If someone again tries to sell the OP a Hanseatic installment loan as equity, they are neither one nor the other but a charlatan

HilfeHilfe, here’s a suggestion before this gets unobjective again, just hold back a little, ok?

1) Better ask which region? Also, it’s supposed to be a new build, maybe read the posts again before making snap judgments. 2) Has there already been an answer regarding substitute collateral, parents’ property? 3) He has at least 8,000 euros, which makes 20,000 euros of equity available, not much but not nothing either. Also, a Hanseatic Bank loan is unnecessary, that’s an irrelevant remark, and if it were appropriate or necessary with an existing property, the concept creator wouldn’t be a charlatan either, because he would then declare that exactly, down to the last cent!

New build, no equity, full repayment in just 23 years, but a desired rate of under 1000€, preferably "800-900€".
That doesn't fit together, many compromises and concessions have to be made. I think that should be clear here, and it has nothing to do with "moralists" and "envy".

Despite all warnings, you can clearly see from Noelmaxim's sales pitch that there is always an intermediary and a bank willing to support such projects.

He has at least €8,000, with which he makes €20,000 equity available

No, he has €8,000 equity and not €20,000. Equity means that it is OWN money. We bankers call the €12,000 loan. Whether it is equity-substitute loan, mezzanine loan, or whatever it is called. The customer has to repay the money and it burdens his liquidity. So please don’t make it look better than it is, the OP gains nothing from it.
