Do I have a right to enter my home now that it was sold at auction in foreclosure - have tenant?

I rented my house out right when I got into foreclosure a few months ago to get some money to try t to bring my house current. I didn't know I could postpone the auction and right on the 120th day it was sold - I only found out from my tenant who signed all the notices on my behalf. I had purchased new appliances for him last month. Can I even enter the house or take my belongings? (window fixtures, appliances, shelves etc.)? It was sold June 3rd :( I hate my lender Citimortgage and Nationstar are crooks they pretended I had a modification and lied to me.
