Investment loan rates  for most loans is linked to the lender’s base rate, which is decided by the banks based on the Reserve Bank of India guidelines. As banks review their base rates at least once in a quarter, your interest rates may go up  based on the call taken by the bank.

Most banks reserve the right to change even the fixed rate at their discretion under various conditions and it may not be possible for the clients to verify this,” says Vipul Patel, director, Home Loan Advisors, a mortgage advisory firm.
