A States report on property shows that 36% of rentals are owned by people with a primary address that is not in Alderney.
The States of Alderney, working with the States of Guernsey, has produced a new, rolling assessment of housing in Alderney.
In terms of affordability, a key issue for young islanders, just 5% were in that bracket.
The report found that house prices have dropped slightly - by 1% in 2023. But on average, the figure remains 7% higher than it was in 2019.
52 houses were sold last year, compared with 43 during 2023. Homes in the £200,000 to £400,000 price bracket were the most popular.
Chairman of Alderney's Housing Group, Iain MacFarlane, says further work will be carried out to assess housing needs:
“Housing is high on the agenda for the States of Alderney and a number of workstreams are underway.
This data is welcomed and is essential in providing the States with an understanding of property stock and prices and how they have changed over time which links directly with availability of housing and the various associated trends.”
Data shows at the end of March '25, there were just over 1,500 domestic properties in Alderney.
Just under half of those 1,510 homes, some 45%, were privately rented.
36% of these were owned by a landlord without a primary address on-island.
That makes 16% of the total housing stock owned by non-Alderney residents.
