What is a good resource to find housing as a civilian contractor moving to Yongsan, South Korea?

Hopefully you get some more specifics responses on here. I have found two articles that one of my Soldiers used while they were going through a similar headache.

Contact a realtor. They will guide you to foreigner friendly housing. They will guide you to more high end housing that is in line with the OHA rates paid to military, DAC, and DODEA. If you need to slum it, make it know. Make sure you understand the rates when it comes to electricity as power is expensive. Some have bottled water included. Trash is fun. I like the area outside of Camp Coiner but parking can be an issue and the skinny steep roads are a pain in the winter. If you want a bit of a commute, you can get cheaper housing and not live around a bunch of foreigners. Traffic may be an issue so ask about that. Subway is an option along with buss.

I contacted the realtor that helped me find housing in Seoul and while she is not there, she gave me a contact, Ashley is her name and local # is 010-4716-8014. Sora, the realtor I worked with is [login to see] . She wrote me tonight she would have Ashley email me however until then this should be a good start. They took good care of me while I was in Seoul.
