Switching your home loan lender can unlock massive savings, especially when banks waive the standard 0.50% processing fee. In this market roundup, we analyze the current zero-fee balance transfer promotions across SBI, ICICI Bank, Kotak Mahindra Bank, Bank of Baroda, and Axis Bank. ### When does a balance transfer make financial sense? 1. **Rate Differential:** If the new lender offers an interest rate that is at least 0.50% (50 basis points) lower than your current lender. 2. **Remaining Tenure:** If you have more than 7 to 10 years remaining on your loan amortization. 3. **Switching Costs:** When processing fees and statutory stamp charges are minimal, the payback period is under 3 to 6 months.
