The marketing agent says it achieves £753,000 rent each year and is promoted as a 20 year plus investment opportunity.
The Premier Inn at Admiral Park was built in 2021, opened the next year, and has 100 en suite bedrooms and 120 car parking spaces plus motorbike and e-bike racks.
It is Guernsey's only Premier Inn.
Agents Watts and Co say it is an opportunity to buy the freehold on Guernsey's newest purpose built hotel, which has a lease guaranteed by the Whitbread Group.
It is being sold with certain insurance cover and construction warranties.
Watts say a reasonable offer for the near 21 years that remains would be in the region of £16M and say it could appeal to a Collective Investment Scheme, among others.
The agent says that the rent is reviewed every five years with the next due within the year. There is an option to extend the lease by ten years.
