So Im looking to purchase a used iPad Air from craiglist. But Already having purchased an iPhone that was activation locked, I want to take precaution as to what must be done for me to attain full possession of the device. If the iPad is not wiped, will all I have to do is get the owner to turn off find my iPhone? If the iPad is wiped, all I would need is a wifi connection and make sure I can set it up to my icloud info before the original owner leaves? Is that the only thing I should look for (software-wise)?
