Malaysia-based Felda Investment Corporation (FIC) has put the freehold of the Park City Grand Plaza hotel in London's Kensington on the market.
Colliers International, which is marketing the 50,000 sq ft property, is inviting offers in the region of £45m.
FIC's acquisition of the hotel in 2014 for £61m is reportedly under investigation by the Malaysian Anti-Corruption Commission.
The 77-bedroom hotel also has a restaurant, lounge bar, function room, gym, rear terraces and a garden.
Colin Hall, director in Colliers International's hotel agency division, said: "This is an extensive freehold property, well maintained and in a great location. Available free of brand and management, it provides an excellent opportunity for new owners to mould to their requirements and we are expecting plenty of interest and an early sale."
Deadline for bids is 12pm on 28 September.
