We have sold our house, and when we have moved before, always taken blinds with us, but in this house, we had to have the bay window and dining room custom made as they were an odd size( wooden venetian ones). They won't fit in new house,but they cost £350 four years ago. What's the correct procedure/etiquette for offering or including them in the sale? Do I have to leave them for free, or can I charge extra for them? They're no use to me, but I wouldn't mind £100/£150 towards some for the new place!
