Brian,
I did pretty much the same 3 years ago, moving not to a different country but across the country.
I down sized from a 3 bedroom two bath house on ½ an acre, sold more than half of my belongings, found homes for 2 of my 4 dogs and all 4 of my cats. I did it at 54 years old. If you need any suggestions, please don't hesitate to pm me. I'll be more than glad to discuss things.
The best of luck to you!! I hope to come visit sometime as well.
