Yes, sure, then it's over and out
With that attitude, hardly anyone should buy
And I’m counting on 1.5 salaries, there’s also the option to switch to full-time
My brother and I will also inherit from the grandparents
Nowadays, almost no one can buy sensibly anymore, correct. It’s stated everywhere by now. The hope for an ETF windfall with the KfW money doesn’t help. You admitted elsewhere that you wouldn’t be involved without the extra cash. But have you already added 10% "value increase" to the market value? Or how do you get to the €900,000?
Otherwise: Are you included in the will so that you could already inherit something from your grandparents? Maybe one should also consider that if the nursing home comes, nothing will be left of the big dreamed-of inheritance? This applies equally to grandparents and parents. Nursing care strangely doesn’t get cheaper, and the shortage of skilled workers is yet to come. How long will your inheritance share last? If things go badly, many thousands per month can go out.
Maybe you’re right though – prices keep rising, interest rates don’t, and the economy is booming. And especially important – outdated houses will become a big hit on the market because of upcoming renovation obligations and generate extraordinary proceeds for the heirs, so prices will continue to rise overall.
But no matter how it turns out: As long as each of you alone, with splitting, can cover the installment from one salary, it’s okay in case of emergency. With your €2200 installment, you and your partner should be at €4400 net in tax class III, then the risk is low.
