Which credentials have made a difference for you?
For me, ‘Xactimate Level 2’ plus a Texas All‑Lines adjuster license noticeably bumped callbacks — TSA PreCheck after a hailstorm. Concrete step: if your state doesn’t license adjusters, get Texas All‑Lines as your designated home state and finish Xactimate L1/L2 back-to-back. If you’re going auto, AIC may be a better first cert; are you aiming CAT property or daily?
