Tax implications on joint home loan

Hi,

Im contemplating taking a home loan. I have some queries regarding tax implications:

1. If I take joint home loan with my wife, both of us can avail the 2 lakh pa interest tax benefit?

2. If the property if rented or let out, one can avail tax benefit on entire interest pay out. What if im not living in my property and have also not rented it out? My tax benefit will be 2 lakhs pa or entire interest?

3. Im living in the same city as my property in a rented accomodation and availing HRA. Would that continue?

Thanks so much in advance!
