Under the deal, which earns MWB £86m, Malmaison properties in Birmingham, Newcastle and Manchester have been sold to Legal and General Property Limited. The fourth hotel in Charterhouse Square, London, was sold to DEKA Immobilien GmbH.
In a statement MWB said the proceeds would go towards reducing the group's £272m debts.
"In light of the stated intention of the Board to reduce debt levels, management has concluded that these transactions will be an advantageous way for the group to significantly reduce indebtedness without compromising the operations of the group," it said.
"Following the transactions Malmaison will retain its robust asset backing, with 80 per cent of its 26-stong Malmaison and Hotel du Vin branded hotel portfolio (by number) being freehold or long leasehold."
The day-to-day operations of each of the four hotels are not expected to be affected by the deal, which will see MWB enter a 70 year lease term on each property with their owners.
MWB will pay £6m in rent across the four hotels in the first year and rent reviews will happen every five years.
MWB chief executive Richard Balfour-Lynn said: "I am pleased that we have made great progress along the path towards achieving more suitable debt levels within both Malmaison and the Group. We are fortunate to have the confidence of such strong institutions that recognise the outstanding long term prospects of our hotel businesses."
In an interview with BigHospitality two weeks ago Robin Cook, chief executive of Malmaison and the Hotel du Vin Group, had hinted that the group may look at sales and leasebacks on properties to raise capital for potential expansion overseas.
Cook also said Malmaison had been looking at properties in the States for potential growth, although would wait for the end of the recession before it made any move to expand.
He said: “Malmaison is in locations where we need it to be in the UK and we need to take it overseas now. I think the brand will do well in America either as a conversion brand or new build, and if we go there we’ll go for secondary cities like the Austin, Houston or Atlanta rather than New York or Chicago.”
