The Seoul housing price issue is because the country is too concentrated in the metropolitan area. It's unavoidable...

The problem in the provinces is that there are no apartment transactions..
At least metropolitan cities can defend their housing prices..

Even I live in the metropolitan area right now (I have to work in the metropolitan area to do designated driver services lol)
The first priority is creating jobs in the provinces and sending people there. If you do that, people will naturally move down..
