Foreclosure tenant unknown if lying in wait

[Joseph Bogart]

I bought a property (condo) at a foreclosure auction and I am waiting for the deed. I have been by the property a couple times and the blinds are closed but there is a light on inside. I have knocked on the door and never an answer. After receiving the deed I was going to first talk to the association office and gather any info from them about the property and if they think anyone is living in the property.  What should I be doing while waiting for the deed?   Is the next step a locksmith? I don’t want to get shot when I open the door. Thanks for all suggestions.
