As a fan of flamenco, I would love to be moving to Andalucia and to spend my remaining years there.
But if you bought the Genos, because it was a useful instrument, then surely it is not so bulky that it can't be transported and have a place with you there in Spain?
You could entertain the locals where you will be living, and it would give you an opportunity to help you integrate with your new neighbours.
Remember that music is an art form that helps to draw people together. Don't sell an instrument that could help you make new friends. That's just my thoughts.
