I’m writing because we renovated a semi-detached house from 1921. First of all: I love our house!
Have a roofer assess the roof first. Electrical system, how old is it? If you’re going to tear up everything anyway because of the wiring and bathrooms, better do it all at once. For safety reasons and because you won’t want to do it later when living there. How old is the interior plaster? The outside is currently not insulated at all, or how should that be understood? Leveling wooden beam ceilings: yes, can be done. Costs a bit and is quite a lot of work, but pays off in terms of impact sound insulation and comfort. Depending on how many layers have been added over the 100 years and which system you choose for the new floor build-up, it can turn out well or be a complete failure (connections to stairs etc.). Without enormous effort, you won’t get it like a concrete ceiling. Floors are basically the same in such houses. What’s interesting is primarily where the beams run, how thick they are and the overall floor construction. Only then do you know what the statics allow in terms of larger tubs or similar. From my experience, I’d recommend checking “under the lady’s skirt” first anyway. Then you know where you stand.
Simply replacing the gas boiler? Why? How old is it? The boiler itself can be replaced later without much effort. How old is the exterior plaster? I would really go all in here: new insulation, new proper windows and doors. Yes, it costs a lot, but to take double glazing now and no insulation? Keep in mind, you currently only have gas (consumption/energy costs). But well, everyone has to decide for themselves, some save the money for insulation. Read up on what obligations might come with this. From your description, it should be about 120 m² or a bit more?

This is crystal-ball gazing. We don’t know what is really necessary, nor your expectations, and at the moment construction costs are exploding, including material costs. The €100,000 might easily be enough or far from it, it depends on too many factors. Especially items like roof, facade, etc. are all major expenses and you have to see what makes sense.

The electricity is from the 80s. But bathrooms aside. I understand that we should rather do the electricity right away :)

Correct. There are bricks on the house. That’s it.

As it looks, not that many. There is only carpet/tiles on it.

There is already a shower and tub installed in the existing bathroom. So one would have to check whether that part of the ceiling is particularly reinforced compared to the previously normal living rooms, right?

We would have done it now directly because in the end it is probably the most cost-effective item, which takes up a rather small part of the total budget.
And the existing boiler only needs to heat. We would still have to check whether it has enough heating capacity for hot water, especially when showering.

A bit more. It’s 135 sqm.

Ok, so the electrical system is about 40 years old. Get rid of it! Regarding the facade; sometimes you get lucky and there is a cavity behind it that can be filled with blown-in insulation. Brick cladding is quite good (does it look good?) and high-quality, so I would also consider if there isn’t an option to leave it on.
I don’t think anything will be especially reinforced, but of course that would have to be checked. Actually, the owners should know that kind of thing.
So you need to have the boiler checked anyway. It was the same with us (boiler from 2010). Ours still had enough buffer to heat the attic after conversion.

You definitely need information on exactly how the ceiling/floor construction looks. Not just for bathrooms, but also for dry screed or whatever you plan. Floor constructions often resemble each other, but here and there you can be surprised by narrow beams that don’t have much buffer upwards for additional weight. We looked inside out of interest during the renovation of a room this year and were even surprised how thick the beams in our house actually are.

If the electrical system in a house from the 1920s was "renewed" in the 1980s, this usually only means "sockets converted to SchuKo and cables no longer in braided sheaths," but very rarely a complete redesign. Between the year of construction and today there was a world war, but on the other hand, not every building authority archive was bombed out. So chances of finding old building records are by no means automatically zero. Also, as I almost always say with terraced houses: in this construction period, you are rarely the first to renovate. You can make use of the similarity of the "siblings" and inquire about what has already been clarified regarding the construction method. Around the ceiling holes for the stairs and downpipes are often the best opportunities to study the ceiling structures.

The tip about the neighbors is worth its weight in gold. That has already helped us a lot - the neighbors who have already renovated often know what the floors look like, what kind of walls you have, etc. You can get good tips from them!

well, I find the price very very very ambitious. The market value wasn’t exactly randomly determined, so the asking price is due to "let’s see if I can find someone...".

Take a look at boris, there you’ll find the 2020 market report. Rhine houses of that construction year averaged €1190/sqm living space, which can be used as a benchmark.

I can hardly imagine that a bank would go along with a market value of €190,000 and purchase price + incidental purchase costs + renovation = €450,000. Banks also determine their lending value ...
