Property sale and home loan interest exemptions

Hello, I took possession of an apartment in Aug-2010 and sold it in Jan-2015.

1. In the FY2014-15 ITR return, can I claim the 1/5th of the pre-construction interest in FY2014-15, i.e. in the year of the sale ?

2. Can I claim the interest paid till Jan-2015 when the home loan was foreclosed in the FY2014-15 ITR return ?

3. If on this sale, I am making a loss after considering indexation, can this loss be carried forward ?

Please advise. Many Thanks.
