For homes in Placer County go to: http://www.placer.ca.gov/departments/tax/taxes/taxbillsearch. Looks like the look-up feature is temporarily down on this site but will be back up later this week.
This way you should be able to look up any property as long as you have the assessor parcel number. Otherwise, working with a good real estate agent will get you this information as needed.
