Dear Sir,
In case of house property if you jointly own the share of house property than same shall be subject to tax at the share of property only and hence your wife will able to claim loss to the extent of her share and you will able to claim loss from house property to the extent of your share only.
However if the entire funding is done from your account only. Means Down Payment, Property Acquisition charges and total loan repayment than you can claim the entire amount of housing loss in your name considering you are the only owner of the property and your wife do not own any financial stake in the property.
But mind that by claiming and putting this argument this will also result into 100% Capital gain tax at the time of sale of property and tax liability shall not be divided at that point of time.
