Twin-track strategy
SARFAESI defence (13(3A) reply / DRT-SA) buys time while OTS negotiation runs in parallel with HDFC Bank's home-loan recovery cell.
Discount range
HDFC Bank home loan OTS typically closes at 65–85% of principal depending on age of NPA and current market valuation of the property.
Stopping the auction
Filing a DRT Securitisation Application with credible grounds + a sanctioned OTS proposal is the most reliable way to halt a HDFC Bank auction.
Process
Notice audit → DRT-SA (if needed) → OTS proposal to HDFC Bank → negotiation → sanction → payment → NOC + mortgage release.
