Initially the idea was that a foreigner can buy a property in Mauritius and if the value is equal to or above $500,000 (USD) then the buyer would gain Mauritian Residency.

The Integrated Resorts Scheme (IRS) and then subsequently the Real Estate Scheme (RES) was launched to allow foreigners to buy property within certain rules/guidelines.

this sounds like a great deal for foreigners who seek to invest in Mauritius
