Is it possible for foreigners to find a studio apartment in Gangnam?

Question

Hello! I'm a foreigner who has been in Korea for about 6 months now. I'm currently looking for a one-room apartment in Gangnam, but it's really tough because as soon as I mention that I'm a foreigner, real estate agents reject me.

I'm worried about the high deposit, so I'm wondering if foreigners can also get a lump-sum deposit loan. Does anyone have a similar experience?

I've tried using the Zigbang app and visited about 5 real estate agencies, but they all say it's difficult once they see my foreigner registration card. Can anyone recommend a good real estate agency or app? I would really appreciate it if you could share your experiences!
