How do I buy this REO with someone living in it?

[Justin Dorn]

I met a person who currently lives in a single-family house that they owned just over a year ago but lost in foreclosure. The property became REO one year ago. They are still living in the property (not sure how, due to Covid?). How can I go about trying to buy this property? I have the company name of the firm managing the REO. What would the process look like? Would they be interested in me contacting them to buy it or do they follow some predefined process that involves auction or listing etc that sends it to the market? I'm hoping to buy this for the amount owed, which would be a nice discount to market value. Thanks!
