When Should You Refinance?

A practical guide to refinancing your mortgage - when it makes sense, costs to consider, and how to switch.

By J2C Mortgage Advisory · Reviewed 15 January 2025

Refinancing means switching your home loan to a different lender or product. Done right, it can save you thousands. This guide helps you decide if refinancing is right for you.

Reasons to Consider Refinancing

  • Lower interest rate: The most common reason—rates change, and loyalty doesn't always pay
  • Better features: Offset accounts, redraw facilities, flexible repayments
  • Access equity: Tap into your home's increased value
  • Consolidate debts: Roll high-interest debts into your mortgage
  • Change loan type: Switch from fixed to variable or vice versa

How Much Could You Save?

The potential savings depend on your loan size and the rate difference:

Loan AmountRate ReductionAnnual Saving
$500,0000.50%~$2,500
$500,0001.00%~$5,000
$750,0000.50%~$3,750

Costs to Consider

  • Discharge fee: $150-$400 from your current lender
  • Government fees: ~$200 for mortgage registration
  • Valuation fee: Often free, sometimes $200-$400
  • Break costs: Can be significant if breaking a fixed rate

Warning: Fixed Rate Break Costs

If you're on a fixed rate, breaking early can cost thousands—sometimes tens of thousands. Always get a break cost quote before proceeding.

The Break-Even Point

Calculate how long it takes for savings to exceed costs:

Break-even months = Switching costs ÷ Monthly savings

If you plan to stay in your loan longer than the break-even point, refinancing makes sense.

The Refinancing Process

  1. Review your current loan: Know your rate, balance, and any break costs
  2. Compare options: We search 30+ lenders for better deals
  3. Apply for new loan: Similar to your original application
  4. Valuation: New lender values your property
  5. Settlement: New loan pays out old loan (2-4 weeks)

When NOT to Refinance

  • You're about to apply for more credit (delays other applications)
  • Your property value has dropped significantly
  • You're planning to sell soon
  • Break costs exceed potential savings
  • Your financial situation has changed negatively
