Why there are no dumb questions here

Every one of these answers ends the same way it should: with something you can check yourself, or a document you're entitled to ask for. That's the whole idea. A sales conversation that answers a basic question with paperwork is doing its job; one that answers it with reassurance and a nudge to decide faster is telling you something too — independent of which question you asked. Ask the “silly” one anyway. On a purchase this size, the person who keeps asking until they actually understand is the one who ends up safe.
