This was the first house hunters internation show that I've seen that takes place in South Korea. Normally when people are moving it tends to be to a much warmer climate.
In this show we follow to Americans who are moving to South Korea to teach english as many have done before. And as is common as foreigners they cannot buy a home but must rent.
The intersting twist was that in South Korea they required a Key Money deposit of between $15k and $50k! Key money seems to be a lot like a security deposit on the rental unit but it certainly would be a significant barrier to moving out on your own for the first time.
In the end this couple of ending up moving into the cheapest and smallest place available. They tended to come up with reasons why they didn't like the more expensive homes but my gut told me that it really was the money issue.
