It's never a good idea to sell a rooted device, especially due to compromised security framework caused by the rooting process.
It's typically best to do a full factory reset, and then reflashing the stock recovery and unrooting the device before relocking the bootloader before it goes on sale on a site like Swappa.
Most phone users don't care about root, so it makes logical sense to go through the hoops of unrooting and relocking a device to its full original state before it goes on to a new owner. Gives them extra peace-of-mind.
