Help on Trustee Owner's Information

[Tim McGarvey]

I just completed running a list of addresses (found driving for dollars) through Santa Clara County assessor's office system to find information about the owners. Quite a few (maybe 15%) of the owner's names say "Trustee" next to them. What exactly does this mean? That the home was foreclosed on and the Trustee took ownership? Is it worth my life to market to these houses? Do the trustee's have authority to make any decisions about the home?

Lot's of questions, any advice would be much appreciated.
