The thought "you don't have to pay it off until retirement" is quite interesting. The children will still inherit enough if they inherit half a house in Wolfratshausen.... But it wouldn’t be anything for me either.
Thank you very much for your comparison (and that so late at night)!
We are also considering selling the house again after 10 years, when the garden is no longer so interesting for the children, and looking for something smaller nearby.
What does my wife say? Better bite the bullet now and buy instead of risking ending up empty-handed in the end. I am more the one who ponders.
Pro: At the end of the month there is still a positive balance with about 500 euros buffer (1500 euros if I spread the annual payment over the month) even with a vacation budget, and at least I know what I work and save for. In the worst-case scenario (getting stuck in MUC) I already question the sense. Working just for the portfolio and not living where I want would frustrate me.
Contra: You simply sleep better with a decent amount of money in the account because a lot can happen and you are still secured. What suffers significantly is retirement provision. I would only consider the house as retirement provision to some extent, because if the house is only sold in 30 years, the demographics will look completely different and maybe the property then, inflation-adjusted, is worth only half or a third because there will be more sellers than buyers with price undercutting competition.
Otherwise, as mentioned above, it remains a roulette game: If only more expensive things come onto the market: Did everything right. If cheaper offers (with smaller plots) or several rental houses come onto the market: How could we have done that?
