The basic idea is easy enough: a government offers the right to live there to overseas buyers who commit a minimum sum in famagusta property for sale. The threshold varies widely from country to country, and governments change it with limited notice.
An important distinction divides residence and citizenship. A residence permit lets you live locally, typically with renewals, while a passport usually demands a long period of residence. Any offer of nationality simply for buying an apartment is reason for caution.
Beyond the purchase price, these schemes impose additional requirements. Common ones include proof of no criminal record, private health insurance, evidence of sufficient means and a minimum number of days in the country per year.
