I have applied for the SBI Top Up Home Loan, also called as the Equity Loan, which requires the existing Guarantor of the Home Loan to be the guarantor of the Top Up Loan as well. But, my Home Loan guarantor is reluctant to become the Guarantor for the Top Up Loan. Is there a way so that I can change my Guarantor of the Home Loan so that I can get Top Up Loan ?
