Put down a deposit which you get back, and also pay rent. The bigger your deposit the lower your rent is, and if you put down a big enough deposit your rent could be zero depending on how nice the place is and where it’s located. Lately, though, nobody seems to want to do the big deposit/no rent deal, probably because interest rates are so bad. The Korean economy tends to follow the U.S. economy, see.
