Finding out bank and money owed on REO

[Rob Leonard]

Good day to all,

I am a regular Joe looking to buy a house. After probing a little on the internet about a prospective home, I found out through RealtyTrac that the property is an REO. County records indicate the REO to be in title to a trustee. My question is. How do I track down the Beneficiary(bank) and how much is owed on the RE? Please explain as simply as possible.
Thank you for all information given!

Gratefully,
Rob
