MetLife will provide £149.5m and TH Real Estate, acting on behalf of TIAA-CREF, will advance £124.6m for the properties, which have a yield of 5%.
The term of the fixed-rate loan is 10 years and loan-to-value ratio is 55%.

Peng Han Lee of Gaw Capital Partners said: “This is a rare and wonderful opportunity to reunite such a large estate in a prime area of London’s West End after two decades of separate ownership.”
