Please check out the link below. Though we don't display information on spending, we do show figures for household income, and under the Community Links section you will find links to various reports on census data that may include spending information.
I hope this helps!
I was unable to locate detailed data like you mentioned on Trulia, it does have some crime and income figures however. You can also check out my website for crime, workforce, and income figures. Click on "Local Resources" then click on "community profile".
Hope that helps,
