Locate Guernsey says it helped 35 wealthy people relocate to the island in 2019.
The organisation is part of Guernsey's Committee for Economic Development and works to attract wealthy individuals to live and work in the island.
Guernsey States says the figure for 2019 was 11 higher than it was in 2018.
The sale of houses on the open market generated more than £1.2 million in document duty for the exchequer - a rise of more than £422,000 on the previous year.
Deputy Charles Parkinson, President of the Economic Development Committee, praised the results.
It is fantastic to see another year of continued success and growth from Locate Guernsey. The associated new businesses, property transactions and personal expertise provide rich benefits to our economy and community. These results provide further evidence for the rising appeal of Guernsey as an attractive location to live and work.
Locate Guernsey received 222 enquiries over the course of 2019 from people in the UK and across the world.
The team continues to externalise Guernsey’s appeal to high net-worth individuals and business owners to ensure the relocation opportunity is clear and visible. Data indicates that there is a growing awareness of the benefits of Guernsey and our ambitious plans for 2020 will build on this.
