With interest rates that have been divided by 4-5x in the last 15 years, small deposits and monthly rents aren't that rare anymore.
I'm not sure how it affects the poorest families, I imagine that you can stay in a decrepit "villa" on jeonse alone for many years. More often than not, real-estate loses value and it might not be in the landlord's interest to kick you out.
But in recent years there are definitely a lot of lower-income families that bought property and got out of jeonse, since it makes no sense anymore.
