It doesn't work without equity - experience!

Respect. But nothing must go wrong there.

Sorry, but stupid remark – with most financings nothing must go wrong. No matter if it's 600 or 1600 euros burden per month.

If I lose my job and don't find anything remotely suitable, the house is gone too – that's how it is and we were aware of that beforehand. At least we would have had a few cool years

Respect. But nothing must go wrong. Or you are a civil servant Then it’s of course more relaxed..

Not everyone earns 10,000 a month and pays such an installment out of petty cash.
Moreover, having hardly any relevant equity does not necessarily mean that there is only a small income.

If it were according to your standards, 80% of builders would not be allowed to build ... I’d rather say nothing about our financial situation, otherwise I might still get stoned

Even if you feel attacked... I stick to my opinion: 420,000 EURO without much equity and over 29 years... I would only dare that as a civil servant*. The income can't be huge, otherwise one would hardly set up such a financing. For me, it's less about the income (which is almost never secure anyway) and more about the equity ratio. If we only had 10% equity, I would have a maximum loan of 300,000. You just have to be more modest. We have >30% equity and even that is too little for me for a 500k loan. The only reason why I am doing it anyway -> there is still a larger reserve. All of this is completely independent of my (current!) income. With this, of course, we would have gotten significantly more credit -> cobbler, stick to your last

* feel free to call me a coward

You with your security. We are all pretty screwed when the crisis comes and the banks find a legal way to change their contract terms (as happened in the USA a few years ago), then no one will be able to service their loans anymore and we will lose our houses (again, the reference to the USA). The good thing about this scenario: it happens to pretty much everyone
So you security fanatics. Those who are smart simply DON'T build AT ALL. We'll crash and then just fall flat on our faces even harder... but we lived it up

Who is smart simply DOES NOT build AT ALL. We go all out and then just fall flat on our faces all the more...but we went all out

Great! I like it!!!

Even if you feel attacked

Who felt attacked? It’s simply that your point of view may apply to you as a self-employed person, but for all other ordinary employees it is completely unrealistic and utopian. And you always let that show in such discussions here.

I care less about the income (which is almost never secure), and more about the equity ratio.

The risk is totally irrelevant to how high the equity share is. Whether I have 500k€ debt with 500k€ equity or only with 100€ equity, the risk of losing the house depends solely on the income/expense situation. The equity used is lost anyway and no longer counts at that point. In the necessary sale afterward, it can make life much easier, but the house is lost anyway. However, if I "hold out" the first 10 years, I have exactly the same situation as if I had had more equity at the beginning.
