In this specific case the 1 EUR home is a blight in the community that makes the whole place less attractive, so it makes sense you'd have to "pay" someone to take it and fix it because it creates negative value for the rest of the place.
That is likely to lead to moral hazard issues though so i doubt it would work in the real world.
All I am saying is that while this makes sense, there is probably some stupid IT system or regulation wording, rather some moral constraints that resets things to 1 EUR.
