I believe the answer is:
tenant
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">renter</span>' is the definition.<br/ ><span class="explanation-format__explanation">(synonyms)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for tenant that I've seen before include "Occupier of rented property" , "his flat?" , "he or she rents" , "one paying rent" , "Person renting property" .)
