<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">property seller</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for estate agent that I've seen before include "Someone who arranges the buying and selling of property for clients" , "House seller" , "Property seller" , "Property dealer" , "Intermediary in the sale or rental of property" .)
