How do I tell whether a Johns Island agent's market advice is current or two years old?

Telling whether a Johns Island agent's market advice is current comes down to asking for specific recent comparable sales, not general statements about the market, since Johns Island has grown and shifted quickly enough that outdated advice can mislead a buyer badly. An agent should be able to name properties that closed recently and explain how those numbers inform their pricing today. Brian Beatty backs up his advice with a current comparative market analysis rather than a memory of how things used to be.
