With the wall connector, again, you could potentially reduce the barrier for the new owner to consider an EV (a barrier that’s already significantly lower these days compared to 5.5 years ago when we sold our house). Of course in your case, it’s for a Tesla (unless they are willing to buy an adapter), so not quite as universal as a J1772.
If you are prepared to part with the wall connector anyway, I would leave it behind. They may not appreciate it right now, but in the next few years, I bet they will thank you for leaving it.
Your alternative is to remove it and then sell it as used. Sure, you’d make a little cash on it, but for me any way, helping promote EV adoption is worth the couple hundred $$ you might get for it.
