Residential house from the 50s, good condition, renovate or sell?

ok, then I know my upcoming work :)

Although some details are different from the construction plan, partly from the very beginning, partly changed afterwards...

and I was diligent...

Well, then there is no need to redraw anything. Floor plans and sections would be an essential start.

I also consider the construction description to be useful?!

I have left those out for now, mostly concerning the room layout and use...

*gnarf* - why am I not allowed to upload PDFs? Doesn't exactly make it clearer...

Do I understand it correctly. Today you are thinking about a possible co-inheritance in XX years, for a house from the 50s? Exactly my sense of humor.

I also consider a building description to be sensible?!

One that has more changes than printed and significantly contradicts the drawings rather not. I tend to believe the plans here. By construction file, I meant the one at the building authority, not the family album binder for the house. In the official construction file, a building description would rather be unusual, especially in the form presented here. Unusual for the time is that the architect apparently was already meticulously familiar with the new brick format. Savings were probably made mainly through the granny flat, the partial basement, exterior walls, roof construction, and the like—but not as usual anymore on the non-load-bearing interior walls. The window recesses were even given stops, and there is even a flower window. Were the (in-law) parents of the widow the builders?

No, she (?) is thinking about the potential of the property for the time after the current occupant. From the description, I do not assume this case will come only "in XX years."

sort of, but we also have to slowly look where the journey is going... Whether there or somewhere else... Or straight into the camper, off into the wide world, to pick up problems other than real estate...

then it’s probably unusual, it *is* really the file inspection at the building authority...

well, the flower window (you mean in the living room?) was not realized, the other window in the living room wasn’t either... I said, quite a bit has been changed.

And yes, it was the generation before...

No, she (?) is thinking about the potential of the property for the time after the current resident. According to the description, I don’t think this case only comes “in XX years”.

exactly, and see above – we’d like to avoid having to make such sudden imperative decisions all at once again.
