You will only be taxed if you have capital gains.
The tax on the gain will be minimal if you hold the property for at least 5 years.
Under MMSH you have to notify FIC first though you do not need to get FIC's permission now to purchase a property and when you sell it you still have to notify FIC first. Your lawyer will do thaat for you.
If done according to procedures then getting the money out of the country will not pose a problem when FIC is notified.
Again rules may change at any time and usually for the better for MMSH applicants
