The cheapest option is obtaining a long-stay residence permit for a period of 1 year with an opportunity for a renewal every second year up to five years. After the 5-year period the person is entitled to apply for permanent residence. Long-term residence permit for one year can be obtained in any of the following cases:
- Investment in real property by a physical person. The minimum required amount of the investment is BGN 600 000 (approximately EUR 300 000) and the payment must be made via a Bulgarian bank institution. If the foreigners are pensioners (retired) in their own country, there is no minimum of the investment; they can buy a real property at any price;
- Incorporation of a Bulgarian company with a minimum foundation capital of BGN 600 000, whereas the foreigner owns more than 50% of the company shares and the company has invested its capital into real properties on the territory of the Republic of Bulgaria;
- Investment in poorly developed regions by incorporation of a company with a minimum required capital BGN 250000, on the condition that the company has invested the amount of the capital in long-term material and non-material assets and has employed at least 5 Bulgarians, whereas the number of the persons employed is maintained for the duration of the residence permit of the investor.
- Incorporation of a Bulgarian company regardless of the amount of the foundation capital and employment of at least 10 Bulgarians, whereas the number of the persons employed is maintained for the duration of the residence permit of the investor.
