Hra claim rules for joint home loan

I and my husband have taken up a joint home loan for a joint property. It is a let out property. For income tax purposes, is it possible for my husband to claim 100% interest deduction, whereas I take up the rental income on my return? My husband is just paying up the loan and I am running the property on rentals.

I am asking this because my husband says he has to mandatorily show the rent for a second house if he is claiming the interest deduction on his employer's portal.
