FL title question -- seized property?

[Julia Dugger]

I'm interested in a Florida property showing as on the docket for auction next week -- in looking at the transaction history on the property, there's a Certificate of Title (unqualified) in October of this year for $200 that shows the following:

GRANTOR: (JANE DOE) ETAL/UNITED STATES GOV TREAS DEPT ETAL

GRANTEE: BANK OF NEW YORK MELLON TRUSTEE ETAL/ CWALT INC ALTERNATIVE LOAN TRUST 2006 OC1 ETAL

The property is currently listed for sale but showing an "offer accepted" designation. The auction is scheduled for next week. 

I'm trying to understand what's happening here -- it doesn't look like a typical foreclosure sale took place but clearly something happened. Maybe it's a federal asset seizure of some kind?
