Read the termination clause before you assume anything carries over. A listing agreement typically runs for a set term, often 60 to 90 days, and ending it early can require the seller to cover costs the brokerage already incurred, including photography, video and any paid advertising placed on your behalf.
A new agent will almost always want to reshoot rather than inherit someone else's marketing, both for consistency and because a prior agent's photographer usually retains copyright over their own images regardless of who paid the invoice.
Ask for the file in writing before you sign anywhere else, and have a lawyer review anything that looks like it locks you into paid extras. Get your hand-reviewed valuation from Joel Dyck.
