Independent dealer mailing title

Hi! I'm in the market for a car and I'm seeing one this Sunday. This guy is telling me that he's an independent dealer, and that he'll have me fill out paperwork and I'll have to request a title, and I should get the title in a few weeks. My dad says not to trust this, says it's weird because he SHOULD sign the title over to me the day of. Is this normal in oregon? Buying the car from Washington. Not really sure what to expect, this is my first time buying a car. Can show screenshots for further context if needed.
