Rajkot upgrade: My tax benefit confusion.

Tax benefits for a second home loan are confusing with my current EMI. I'm in a 2BHK on Kalawad Road, eyeing a 3BHK upgrade. If I don't sell my first, can I claim Section 24 interest deduction? Ya dono pe milta hai? Rajkot second property tax rules pe clarity chahiye. Any advice on maximizing deductions for an upgrade here?
