The Plaza complex has gone on sale today for €14 million through agent CBRE.
The complex is being sold on the instructions of receiver Declan Taite of Duff & Phelps and generates a rent roll of €1,302,350 with a net initial yield of 8.91%.
The auctioneers say this could increase when more of the vacant office space in the complex is let.
The six-storey development over double basement includes a four-star, 122-bedroom hotel and basement nightclub, three floors of offices and three ground-floor retail units.
It extends to 18,653sq m (200,779sq ft) on a site of 2.8 acres.
There are also more than 480 car-parking spaces at basement and surface level.
The office accommodation of 6,876sq m (74,012sq ft) is located on the first, fourth and fifth floors.
On the fifth floor, some 2,199sq m (23,670sq ft) is vacant, offering an obvious opportunity to increase the rent roll.
All the remaining office space is occupied by the OPW, which has more than 7.6 years left on its lease with no break options.
