what are some elizbeth II's private residences in England that she owns and can sell? (other than Sandringham House)

Many of the most famous residences of the British Monarchy
are in fact owned by the state, such as Buckingham Palace and the Palace of Holyrood
House. These fulfil the role of the official residences of the Queen and the Royal
Family in various areas of the UK.

Other residences, such
as Balmoral Castle (Scotland) and Sandringham (East Anglia) are private residences owned
by the Queen. Their estates are used to generate a private income for the monarchy,
although this is now subject to UK tax.

There is another
category of buildings, those run by the charity Historical Royal Palaces. These are
former residences of the monarchy, which are still owned by the Queen on behalf of the
nation. They include many famous British tourist attractions such as Hampton Court
Palace, the Tower of London, Kew Palace and Kensington Palace. There are also hundreds
of smaller buildings and hoes which the monarchy own. Many of these are no larger than
cottages, and may be sold by the Crown Estates. However, buildings of
national significance, such as the palaces, cannot be sold.
