What is the depreciation value of an 11-year-old built-in kitchen?

Long story, the buyer was a relative of the painter. Everything was settled a bit between them. So, in the end, she sold the kitchen for €900, or rather gave the kitchen away and got the whole house painted.

Not really given away at 900€, usually worth nothing after 10 years
