Selling a kitchen to someone in another apartment - Berlin

I'm selling my apartment and the buyer wants to install his own kitchen rather than take mine. If the new apartment I find already has a kitchen, what can I do with mine? Is it possible to sell it to someone who can take it out of my apartment and install it in their own?

Off course you can advertise it on eBay and the likes. It will sell.

Sure, if you get the timing right, why not?
