Purchase of an old apartment, renovation costs

Well, the recommendation is 30 years, that would be exactly the range and if it were my property where my children live, the electrical system would be important to me

Problem with electricity is you don't see it until it burns and then it's too late

For an apartment that is about 20 years old and is going to be lived in for about 10 years, I would definitely redo the electrical wiring

One could also take the money and throw it out the open window. It's basically the same thing.

And that’s exactly why I rarely write here. The question was about possible costs that might arise and when. Then you answer it and get yelled at. Sorry, I’m out.

Then you answer and get snapped at. Sorry, I'm out

You don’t get snapped at, you get corrected – some more factually than others.

The problem with electricity is you can’t see it until it burns, and then it’s too late

A short circuit or fire occurs when the power is overstressed or the wiring is tampered with. That has nothing to do with modern electrical systems, which can also be 20 years old.

Or if the clamping connections get worse and worse over the years.
