Can I declare pre-closed home loan details in tax filing?

I applied for a home loan in feb-2012 and I paid pre-emi for 4 months [till may-2012] and I paid full EMI till dec-2012 after which I pre-closed the home loan account [by actually selling the property]. Can I mention the principal repaid / interest paid on home loan / income/loss from house property, when I submit my tax proofs for this financial year?
