How safe is buying used Moto X Pure?

I have accounts on Verizon and T-Mobile and generally buy phones used. With Verizon-branded phones this is quite safe-- meet the person at Verizon store, have the phone added to my account, and no worries about it subsequently being reported lost or stolen or otherwise blocked/blacklisted. With T-Mobile, completely unsafe. No matter what they tell you at the store about the phone, it can subsequently be blocked or blacklisted for a variety of reasons.

If I buy a Moto X Pure and add it to my Verizon account, am I safe? Or could it still be blacklisted by, say, an insurance claim?
