I don't think she's had to provide her own housing ever. She went from school to Paddy McNally's chalet. Then didn't she have flatmates? Met Andrew. Didn't they live at Buckingham Palace? Divorce: queen bought her a house. She sold the house. Moved in with Andrew again? Been there ever since. She's never provided for herself, even with all her "endorsements" and books... She just lets money slip through her fingers like water.
