When to Refinance Your Home Loan

Refinancing means replacing your existing mortgage with a new one. The maximum you can refinance a house depends on your lender’s policies and the usable equity in your property. 

In Sydney’s Northern Beaches, where median house prices have reached approximately $2.7 million in 2024, rising property values can increase your equity, allowing many homeowners to refinance up to 80% of their home’s value without lenders mortgage insurance. 

This growing market offers opportunities for accessing additional funds for renovations or investments.

But when’s the right time to refinance? Generally, you should consider refinancing if:

• Interest rates drop: Lower rates can save you thousands over the loan term.
• Your financial situation improves: A better credit score or income could unlock more competitive rates.
• You need to access equity: Equity can be used for an investment property, granny flat construction, or renovations.
• Your current lender isn’t competitive: Switching to a new lender with better service or terms could be worthwhile.

Speak to mortgage brokers who understand the Northern Beaches property market. They can help you identify the right moment and guide you through the mortgage process seamlessly.

Top 10 Tips on How to Refinance a Home Loan

Thinking of refinancing? Here are 10 actionable tips to help you secure the best deal for your Northern Beaches home loan.

#1  Check Your Current Home Loan Terms

Start by reviewing the details of your existing mortgage, including your outstanding balance, current interest rate, and any associated fees like break costs. Understanding these terms will help you determine if refinancing is financially worthwhile and aligns with your goals.

What you can do: Review your loan statement and speak to your current lender or mortgage broker for clarification.

#2  Improve Your Credit Score

Your credit score plays a key role in determining the interest rates and loan options available to you. A higher score can unlock more competitive rates and better loan products, potentially saving you thousands over the life of your loan.

What you can do: Pay bills on time, lower your credit card balance, and avoid new debt before applying.

#3  Know Your Property’s Current Value

Learning your home’s current value is crucial when refinancing, as it determines how much equity you can access. In Northern Beaches, rising property values may provide you with more usable equity to fund renovations, investments, or reduce your mortgage balance.

What you can do: Obtain a property valuation from your lender or consult a local real estate agent to get an accurate estimate of your home’s current market value.

#4  Understand Refinancing Costs

Refinancing can come with several costs, such as application fees, property valuation fees, and potential break costs if you exit your current loan early. These expenses can add up, so it’s essential to calculate whether the savings from refinancing will outweigh the upfront costs.

What you can do: Request a detailed comparison of all fees, including application and valuation costs, from potential lenders to ensure you fully understand the expenses involved in refinancing.

#5  Shop Around for Competitive Rates 

Not all lenders offer the same rates or loan terms, so it’s important to compare options across a range of lenders to find the best fit. Exploring different products can help you secure a loan that aligns with your financial goals and offers the most potential savings.

What you can do: Use mortgage brokers who can access hundreds of financial products and negotiate for you.

#6  Decide Between Fixed and Variable Rates

When refinancing, you’ll need to choose between fixed rate and variable interest rates. Fixed rates provide stability with consistent repayments, while variable rates offer flexibility and the potential to save if rates drop.

What you can do: Assess your financial situation and loan term to determine whether a fixed or variable rate is the best option for your refinancing needs.

#7  Use a Mortgage Offset Account 

A mortgage offset account links to your loan and allows you to reduce the interest charged by offsetting the balance with your savings. Over time, this can significantly lower the overall cost of your mortgage and help you pay it off faster.

What you can do: Speak with your mortgage broker to understand how offset account options could work for your loan and help you save on interest over time.

#8  Avoid Over-Borrowing

When refinancing, it’s important to borrow only what you truly need. Overextending yourself with a larger loan than necessary can lead to mortgage stress and make it harder to meet your monthly repayments.

What you can do: Focus on your property goals and stick to a manageable budget.

#9  Refinance for Investment Potential

Refinancing can unlock the equity in your home, giving you the funds to grow your investment portfolio. This could include purchasing rental properties, building a granny flat, or pursuing other property investment opportunities that align with your financial goals.

What you can do: Collaborate with financial advisors and real estate agents to assess rental yields and determine the investment potential of your property.

#10  Get Pre-Approval Before Committing 

Securing conditional pre-approval helps you understand how much you can borrow before finalising your refinancing decision. This gives you clarity and confidence while comparing loan options and ensures you stay within your financial limits.

What you can do: Prepare all required documents, such as proof of income and property details, to complete your loan application and secure pre-approval for a smoother refinancing process.
