Deficiency claims have a 5 year statute of limitations, running from the date of entry of the judgment. Accordingly, a deficiency claim is still timely now.
Once the foreclosure is completed by means of a final judgment, there is no more mortgage. Accordingly, an assignment of rights to a deficiency claim would not be the same as an assignment of mortgage.
Whether it is a valid debt depends on many details. You should immediately contact an attorney who is knowledgable in foreclosure-related litigation and deficiency litigation unless you have obtained a bankruptcy discharge, or unless you intend to pursue bankruptcy instead.
