Stock in trade under houseproperty

under the head houseproperty, there is a topic of stock in trade of business
here, one sentence is given that if stock in trade is not let out and certificate of completion of construction is given then up to two years , annual value will be nil.
my question is....

if assessee has taken loan on houseproperty which construction is completed but it is stock in trade...then interest on such loan will be deducted???
