Need to wait 5 years though, to get residency. In Cyprus 300k property investment for residency in 6 months, 2 Million gets you citizenship in 6 months.
Edit: The Citizenship in 6 months is no longer available as of November last year, residency still applies but it's non schengen so doesnt...
Buy a property in Cyprus worth 2 million euro.
As a UK citizen you have the right to live in Ireland, and apply for naturalisation or permanent residency after a period.
