Keyser died in 1929, at the age of 81. His death certificate lists the place of death as Bucklebury. Keyser's estate was valued at £770,000, resulting in an Inheritance Tax of £150,000. The lessened agricultural income from the estate was then less than the cost of its maintenance in 1929. Keyser's wife, Mary died in 1938. Their son, Charles Norman, had no interest in running the estate and his heavy asthma led him to move to Adderbury, Oxfordshire. Muriel and Sybil, their daughters, had expensive taste with racehorses and ponies, and their brother sold the whole estate to a syndicate, Messrs Cribble, Booth and Shepherd, for £100,000 who auctioned it in lots at Reading Town Hall, beginning on 20 September 1939. Many of the lots were bought by their occupants. The house and its immediate grounds were bought by Associated Electrical Industries (AEI) for £16,000.
