Income tax savings on Home Loan

I am planning to take a home loan of 50 Lakhs.  My wife is a housewife and she is also looking for job.

What are some tax savings ideas that will be beneficial in the future?

These are some doubts

1. Can home loan account be a joint account ? 

2. Can my wife get tax benefit  in case she get job in future

3. Does bank allow co-applicant who is housewife
