Please show me how to buy a house on FEDHomes.com

I see a house that I wanted to buy on the website FEDHomes.com.
Who should I contact because I don’t see any contact information on there at all.
Please give me some advise because I so new to this.
Thank you.

I’m pretty sure it’s already bank-owned if it’s listed on the site. If there’s no agent listed, I would try any real estate agent and have them find it in MLS.
