Here's an idea that I'd like to put forward.
Please don't let it blow your mind.
(1) Take the company villa in the generic location with all bills and maintenance paid.
(2) Keep your house in your home country, pay it off as quickly as possible by saving as much money as possible in Dubai - and if you have any left over invest in a buy-to-let property in a 'traditional' country where your value is secure in the long-term and not subject to speculation bubbles and nearby wars.
(3) Go home when fed up and paid up.
Or am I being too safe and boring?
