Understanding Rate Lock-ins

When you're buying your first home, choosing between a fixed interest rate and a variable interest rate can feel overwhelming. A rate lock-in allows you to secure a specific fixed interest rate for your home loan before settlement, protecting you from potential rate increases during the construction or settlement period.

A rate lock-in is particularly valuable when you've applied for a home loan but won't settle for several months. For instance, if you're purchasing off-the-plan or building a new home in Byford, you might want to lock in the current fixed interest rate rather than risk it increasing before settlement.

Most lenders offer rate lock-in periods ranging from 90 to 120 days, though some extend this to 12 months or more for construction loans. The availability and duration of rate lock-ins vary between lenders, which is where working with a mortgage broker can be particularly helpful.

How Rate Lock-ins Work

Once you receive pre-approval for your first home loan, you can typically request a rate lock-in if you're choosing a fixed interest rate product. This means the lender will honour that rate when your loan settles, even if they've increased rates in the meantime.

Here's what you need to know about the rate lock-in process:

  1. You must have formal loan approval before requesting a rate lock
  2. The lock-in applies only to fixed rate products, not variable interest rate loans
  3. If rates decrease during your lock-in period, you're still committed to the higher locked rate
  4. Rate lock-ins are usually free, but some lenders may charge a small fee
  5. The lock-in expires if you don't settle within the specified timeframe

For first home buyers using schemes like the First Home Loan Deposit Scheme or accessing low deposit options with a 5% deposit or 10% deposit, understanding rate lock-ins becomes even more important when planning your first home budget.

What Are Break Costs?

Break costs (also called early exit fees or break fees) are charges that lenders may impose when you pay off your fixed rate loan early or make extra repayments beyond the permitted limit. These costs exist because when you lock in a fixed interest rate, the lender effectively borrows money at wholesale rates to fund your loan for that fixed period.

When you break a fixed rate contract, the lender may face a financial loss if wholesale rates have fallen since you took out your loan. The break cost compensates the lender for this potential loss.

Common scenarios that trigger break costs include:

  • Refinancing your home loan during the fixed rate period
  • Selling your property before the fixed term ends
  • Making extra repayments above the annual limit (often $10,000 to $30,000 per year)
  • Switching from a fixed interest rate to a variable interest rate

Calculating Break Costs

Break costs can range from zero to tens of thousands of dollars, depending on several factors:

  • The remaining time on your fixed rate period
  • The difference between your fixed interest rate and current market rates
  • Your outstanding loan balance
  • The lender's specific calculation method

If market interest rates have increased since you fixed your rate, there may be no break cost at all. However, if rates have fallen, break costs can be substantial.

Most lenders provide break cost calculators on their websites, but you can also request an exact figure before proceeding with any changes to your loan. For first home buyers in Byford considering their Home Loan options, it's worth understanding these potential costs before committing to a fixed rate.

Fixed vs Variable: Making the Right Choice

Choosing between a fixed interest rate and variable interest rate depends on your personal circumstances and risk tolerance. Each option offers distinct advantages:

Fixed Interest Rate Benefits:

  • Certainty in your repayments for the fixed period
  • Protection from interest rate increases
  • Easier budgeting and financial planning
  • Rate lock-in options available

Variable Interest Rate Benefits:

  • Usually offers access to an offset account
  • Flexibility with redraw facilities
  • Benefit from interest rate decreases
  • Often allows unlimited extra repayments without penalty
  • May qualify for interest rate discounts

Many first home buyers choose a split loan, fixing a portion of their home loan while keeping the rest variable. This provides some certainty while maintaining flexibility.

Strategies to Minimise Break Costs

If you're considering a fixed rate home loan, here are strategies to avoid or reduce break costs:

  1. Choose the right fixed period: Don't lock in for longer than you need. Consider your plans for the next few years
  2. Understand your loan features: Know your annual extra repayment limits and stay within them
  3. Use an offset account: If available with your fixed loan, this lets you reduce interest without making extra repayments
  4. Time your refinance: If possible, wait until your fixed period ends before refinancing
  5. Consider a split loan: Keep some of your loan variable for flexibility

For first home buyers accessing schemes like the Regional first Home Buyer Guarantee or those eligible for first home buyer stamp duty concessions, understanding these costs helps protect your first home buyer budget.

Questions to Ask Your Lender

Before committing to a fixed rate home loan, ask these important questions:

  • What is the current break cost calculation method?
  • Are there any annual extra repayment allowances?
  • Can I make lump sum payments from a gift deposit without penalty?
  • Does the loan include an offset account or redraw facility?
  • What happens if I need to sell unexpectedly?
  • Are rate lock-in fees applicable?
  • What is the maximum rate lock-in period available?

When you apply for a home loan, having clear answers to these questions helps you make an informed decision about which loan structure suits your needs.

When Fixed Rates Make Sense

Fixed interest rates and rate lock-ins work well for first home buyers who:

  • Value certainty and consistent repayments
  • Believe interest rates will rise
  • Have a tight budget with little room for repayment increases
  • Are building a new home and want to secure current rates
  • Plan to stay in their home for the fixed period
  • Don't anticipate making large extra repayments

For those managing Lenders Mortgage Insurance (LMI) costs or maximising first home buyer grants and first home owner grants (FHOG), the predictability of fixed rates can help with financial planning during those crucial early years of homeownership.
