I believe the answer is:
tenant
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">one pays rent</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for tenant that I've seen before include "Property renter" , "Someone who pays rent" , "Leaseholder" , "He pays rent for lodgings" , "Occupier but not owner" .)
