House purchase upcoming - built in '62, full renovation necessary! Price?

A different question. Is 100 sqm of living space enough for the four of you?

Modernization costs are currently difficult to specify. I have no idea yet what it will cost. Above all, we can't do much ourselves... the "gutting" or disposal and preparation of work (e.g. chasing, floor covering (except tiles), insulating the basement ceiling, etc.) we would take care of... but everything else we would want to have done by an architect or contractor who offers and coordinates everything.

I am curious what the seller will ask for... I hope for an amount around 130k€. With that, a "complete renovation" with our wishes, I think, would also be possible...

No, the extension is supposed to be built on (+20m2). In addition, part of the shed is to be converted into a utility room (another +15m2), and with that we would manage just fine.

Can you actually tell from the drawing and the pictures whether it is a masonry or concrete basement?

Yes, you can: the dimensions of the rooms and the walls indicate "masonry."

Unfortunately, the extension is not on the drawing. It extends from the kitchen door with a width of 6.43m and a depth of 3.23m.

... and it covers the light well of the laundry room, if I’m guessing correctly.

At 500 €/m2 the house rather has a negative value, at 20 €/m2 an ideal one.

That sounds like the cute little house rather tempts you to tear it down?

I wouldn’t tear it down, but only buy it if the condition is good and you don’t care about fashion. The house looks "very well maintained" – but for fans of floor-to-ceiling corner windows, walk-in showers, and open kitchens it would surely be a bottomless pit.

I don't know your real estate market up there, but if the standard land value is €140/m2, I would multiply that by the plot size and since the house only needs renovation but is not ready for demolition, I would roughly add the shell construction costs. So roughly about 140x740+50,000=approx. €150,000 rounded down. But to answer this question properly, you would need to know the market. Nobody is giving anything away for free. A nice old building in a quiet cul-de-sac can go for more on the open market if the market allows it. For example, I find developed plots much more interesting than bare new development area plots. And otherwise, talking helps. The price is THE most important factor. Talk to the seller! Maybe the market is completely different for you and you get it for €100,000, but a local appraiser can surely answer that for you too.

I’m getting back to you. There is now an extract from the land registry office stating 619m2. In addition, we were given a price of €160,000 negotiable. What do you think?

The next question will be: How expensive will the conversion and renovation be? Can it be roughly estimated?
Almost everything has to be new:
Electrical, heating, pipes, structure on the flat roof, extend the dormer and two small dormers on the other side of the roof, insulation,...

Of course, everything depends on our requirements, but what is taken as a benchmark for such an old house?

Thanks for your assessment!
