Interestinggggg. Well, perhaps she should not have sold her childhood home.
It was already owned by the Dutch State, since the 1970s. They have sold it in 2017.
"...Soestdijk Palace is a palace at Amsterdamsestraatweg 1 in Baarn. The original 17th-century building is named after the Soestdijk, along which the hamlet of Soestdijk was also created. From 1937 it was the residence of crown princess and later Queen Juliana of the Netherlands and her husband Prince Bernhard van Lippe-Biesterfeld. From late 1970 to 2017, it was owned by the Dutch State..."
"..During the period of the Marijnen cabinet (1963-1965), there were already plans that the State of the Netherlands would purchase Soestdijk Palace, because of the high maintenance costs.  In 1967, for example, they amounted to 450,000 guilders.  Ultimately, during the cabinet period of Prime Minister De Jong (1967-1971), the government wanted to definitively purchase the palace and surrounding grounds. There were amounts that the palace with a value of 70-75 hectares of land would have a value of ten to twenty million guilders. Because of expected public criticism, the cabinet was reluctant to put such amounts on the table. According to the Ministry of Finance, because of the high maintenance costs, the palace even had a negative value and advised not to offer more than one to three million guilders. De Jong did not want to go beyond one million guilders. Juliana asked 3.3 million guilders at the end of October 1967. A binding valuation was then decided. In September 1970 this came to 4.29 million guilders.  Finally, Soestdijk Palace was sold to the State of the Netherlands at the end of 1970 for an amount of exactly 4.2 million guilders. At the same time, it was established that Juliana and Bernhard could continue to live in the palace even after Juliana stepped down as queen. .."
