The total investment amount is one million pounds. Alternatively, 750 thousand can be invested in British securities, and 250 thousand in real estate. If one's own funds are insufficient to acquire the desired property, British banks are willing to provide a foreign investor with a loan in the ratio of one million pounds of borrowed funds to two million of their own. The price of such generosity is 150-170 thousand pounds as a one-time payment to the lending bank.
As 'Itogi' notes, having a sufficient amount of money frees the investor from all other formalities in obtaining a passport. Except for one - the time spent in the country. But even here, investors are given a concession - they are required to stay on the island for just over six months. As a rule, the spouse 'serves the time', and the entire family receives passports.
The popularity of residence permits under the 'investor' category is explained by the tax-free regime for capital brought into the country: one only needs to pay the difference between the tax rates of Britain and the client's home country when transferring money to Foggy Albion.
