My BFs security clearance asks that and much more. All debts, all assets, assets sold, proof of insured values, addresses of all houses you have lived in, your overseas trips ), your parents and siblings overseas trips, social media and forum memberships, and so on. And they also interview your friends and family to see if the answers match. Plus they visit his house to do the interview so they can look around. Then they repeat it all every 3 years.
The amount of information they require and how deep they dig apparently depends on the clearance level.
