Renovation costs mid-terrace house built in 1995 - and consultation

Thank you for your assessment. Earlier (before I saw your reply), I spoke on the phone with a local floor installer. They said that it might be possible, of course depending on the subfloor, to lay directly over the tiles. But that probably doesn’t change the fact that the screed would still need to be repaired or, in this context, that a demolition would have to be done anyway. In the basement, I could possibly live with leaving the tiles in place. However, I also have the problem with the crack there. If you are not replacing the floor covering anyway, can you then just leave it, or is that a risk (moisture ingress, etc.)? Can it be assumed that there was possibly poor construction work or is this a "normal" phenomenon? What the expert also noticed is that, for example, there is water damage under the bathroom. This can only happen if no sealing was installed there. In general, the expansion joint was forgotten at the transitions from drywall to the sidewall, which is why there are cracks there as well, although these are probably more of an aesthetic concern than a functional one.

We chiseled out the tiles in the living room because of some cracks (and taste). It was definitely a crappy job. But it was definitely worth it – at least for us. We also completely redid the bathrooms, where the floor came out very well. The wall tiles were glued over.

So I would also always tend to dismantle and then rebuild. Of course, in certain rooms you can also tile over or simply plaster wall tiles.

Unfortunately, you can never really foresee beforehand how much work the removal will be. Sometimes the tiles come off almost in one piece and sometimes they crumble and you have to work your way through it laboriously. But you should keep in mind that such work should ideally be done before moving in.

What I rather wonder is which of the two values is more accurate,

But your values differ by only 1k euros. ;)

Sure? 530,000€ and 585,000€ are not 1,000€

Yes, exactly. Then I mistyped. The difference was almost 100,000 euros.
