SV sought for the evaluation of a single-family house in the Krefeld area

For the purpose of determining the value basis for a fair inheritance settlement, I am looking for an expert to appraise a single-family house with a granny flat in the Krefeld area (North Rhine-Westphalia, postal code region 41) and surroundings. I could also search industry directories myself, here I hope for recommendations of someone who would be recommended by a forum member based on their positive experience – but self-recommendations are also welcome.

in the Krefeld area (North Rhine-Westphalia, ZIP code region 41) and surroundings.

Sorry, it should of course be "47".
I’m not quite used to the five-digit ZIP codes yet, as they have only been in effect since 1993 ;-)
