To go or not to go

Gong Xi Fa Cai to all.

Now I am really facing a serious decision to make.  Have been living in Toronto for 10+ and recently got an opportunity to relocate to Hongkong...still in discussion on the package but probably will get a 10 % raise on gross base (140 USD/1.1 M HKD), plus relocation assistant for the family (wife + one 9 year old).  To make things more complicated, I also have options to relocate to NYC or Chicago.

I am not young anymore (just celebrated my 40), and the raise is not huge; but career wise it is definitely a benefit. 

Questions for folks who have similar experience before (relocated to HK from US/Canada):

1. Is it worth it to make such life change (plan to go back to NA in 3-5 years)

2. Have you thought about exit strategy and how easy to go back to NA?

3. Given the info above, would it be a drop on the quality of living in HK?  I know housing in HK is crazy - even though Toronto is crazy too.

4. I probably will propose a lump-sum relocation package for discussion.  What is the number of months's accommodation I should include in the package?  How should I calculate education assistants for my 9 year old?

 

Many Thanks!!
