ChatGPTCheck how much someone with an existing home loan could save by transferring it to another lender. Use when the user mentions their current home loan rate, EMI or lender and asks whether they can do better, refinance, switch banks, or reduce their EMI. Needs the original loan amount, current interest rate, original tenure and loan start date; the outstanding balance is derived from those if not given. Returns lenders ranked by total savings over the remaining tenure.
