My friend is looking for an apartment to rent, don’t you know any good places?
Rent it and I will lend it to you. This thing that is being lent and rented? It's a rental.
This is a jukugo word that uses the on'yomi readings of the kanji. You just have to remember that 貸 is read as たい for this one. What is your rental? It is a tie (たい) fighter. Sweet.
