Purchase opportunity single-family house from the 80s - risk?!

Yes, that's why I said "if everything fits." I don't exactly remember how it looks on your end... Take a look at the house, talk to the bank, then you'll know more ;)

Good luck

Well, your starting position is of course not comparable :) we can't keep up with that. I have relatively good equity, but whether that lasts, I don't know. We have a financing appointment next week. And we are going through the house again with an acquaintance (who was an appraiser, now retired).

Signal interest, "we are very interested," proceed with another appointment with the expert (general condition & costs for renovation needs), and of course clarify the financing with the banks. We have asked here several times - where is actually your pain threshold, and where is the bank's?

The mentioned value is therefore still strongly oriented towards the peak values of the past - you yourself named 600,000€ off the cuff. Your ideal of 500,000€ is only about 15% away from the seller's initial asking price, which should not be an unsolvable problem nowadays. Especially if renovation/restoration definitely exceeds 100,000€...

The issue with the "pain threshold" has always been a bit of a thing. It is very fluid depending on the property and location. Although there is a range, and the house falls within that.
Nevertheless, I would rather pay under 500K.
But it may be that we will not get the property for that because the location is "unfortunately" too popular...

I can only repeat it... If you don't buy it, someone else will. Just because the price is high, and some people keep saying "there’s easily 15% etc. in it," doesn’t mean that it’s actually the case. Location is the most important thing. If everything else fits, people pay the price and that’s it. They want to prevent exactly that someone else comes along and doesn’t want to haggle. High price or not.

You just have to know for yourself whether you are willing to pay this high price. Nothing else matters.

Question on the side: we still have a building savings contract filled with 30 TE, we could take out another 30 TE as a loan (without entry in the land register) at 2 percent (interest and repayment). So 60TE equity, so to speak. Or better to continue saving?

I can only repeat it... If you don't buy it, someone else will.

Me too. Exactly today, someone else could ask the exact same question about the same house in another forum. But they don't, because their financing is more flexible.
