House didn’t sell on HomePath, what happens next?

Hi all, I’ve been watching a house in my local area that was in Fannie Mae HomePath site for over a month. It went pending and now I see that a sheriffs deed was filed last week with the buyer as Fannie Mae at a much lower price than what it was listed at. So my question is, what happens now? How can a make an offer or purchase this home if it’s no longer on homepath or listed for sale? Will it come back onto Homepath eventually? Thanks!
