I found MVC phuket beach club maybe a good choice.I think I can buy one week in high season for ~5000usd and fee per year is 1000usd.If I can have a week durning chinese new year vacation (in early Feb) and rent it in chinese market,I think 2000 usd per week is possible.
I think this resort only works with II ,but as I even have some profits out of fees,it's ok for me.
I don't know how the timeshare rent work in details,I mean,I book (or lock?) a week in advance and later I can give them any guest name who really check in?
I can speak chinese and I think it's not hard for me to find customers if I have a week during chinese year.
