I'm trying to figure out the threshold amount of interest/fees savings in order to make it worthwhile to move lenders (refi). Say I have a $250k loan PPOR no LMI 80% LVR (plain vanilla type of loan), and want to refinance, how much interest and fee savings would it take for it to be worthwhile considering the cost of discharging a loan from old lender and applying for a refi to another lender? I was thinking: Discharge and legal fees to old lender $500 Valuation application and legal fees payable to new lender $500 So the new loan should save me more than $1000 to make this refi sensible? Are there other fees I'm missing? Assuming other things being equal e.g. quality of service or whatever.
