Are you still seeking advice about buying in the Greater Seattle Area? I work with a lot of foreign investors from China and banks that provide loans for them. Many of my clients have chosen to finance their purchases and I can say from my experience that it's not too difficult, but you have to do it right. For example, it requires time to gather all the documentation and if the bank requires it, you must be prepared to move money by a certain date. As long as you're dedicated to following the bank's guidelines, you should be able to finance a purchase here.
