Borrowing Money for Renovations: How Your Mortgage Can Help

Table of Contents

Home renovations are an exciting way to turn your house into your dream home or increase its market value. Let’s face it, renovations can be costly. If you’re wondering whether you can borrow extra money on your mortgage to fund your plans, the answer is yes! At Unconditional Finance, we specialise in helping Australians find the best financing solutions for their renovation goals. 

Borrowing extra money through your mortgage can be a smart financial move, but how does it work in Australia, and is it the right choice for you? Let’s explore the options available and what you need to know to make the best decision.

Why Borrowing on Your Mortgage Can Make Sense

Why do so many Australians turn to their mortgage for renovation funding? Simply put, mortgage rates tend to be much lower than other types of loans, like personal loans or credit cards. Renovations can be expensive, often costing tens of thousands of dollars, so spreading that cost over the long term at a lower interest rate can be a practical and budget-friendly choice.

Imagine you’re planning a $30,000 kitchen renovation. Would you rather pay 20% interest on a personal loan or roll that cost into your mortgage, where rates are closer to 5%? The difference in repayments is substantial, which is why borrowing through your mortgage is so popular.

The Mechanics: How It Works in Australia

Borrowing for renovations often uses your home equity, which is the difference between your home’s value and the amount you still owe. For example, if your home is worth $700,000 and you owe $400,000, your equity is $300,000.

Here’s what you can expect when borrowing for renovations:

Step 1: Consult with Your Lender or Broker

Your first move should be discussing your renovation plans with Sydney mortgage brokers. They’ll help you understand how much you might be eligible to borrow based on your equity and financial situation.

Step 2: Property Valuation

Your lender will assess your home’s market value to calculate your equity.

Step 3: Loan Assessment 

They’ll review your income, expenses, and creditworthiness to ensure you can afford the additional debt.

Step 4: Approval and Disbursement

Once approved, the funds are released, often directly into your account.

Options for Borrowing Extra Money for Renovations

Renovating your home is an exciting journey, but finding the right way to finance it is key. Let’s explore some of the most practical options for borrowing extra money to bring your renovation plans to life.

1. Top-Up Your Existing Mortgage

Topping up your existing mortgage is often the simplest and most straightforward option. This approach involves increasing the loan amount on your current mortgage, giving you access to additional funds while keeping the same lender and loan structure.


If you’ve built up enough equity in your home, your lender might let you borrow some of that equity to fund your renovations. For example, if your property is worth $800,000 and your current mortgage balance is $500,000, you have $300,000 in equity. A top-up might enable you to access part of that equity for renovations, provided you meet the lender’s criteria.

Example:
Imagine you need $50,000 for a bathroom and kitchen renovation. By topping up your mortgage, this amount is added to your existing loan balance, and you’ll continue making payments as before but with a higher total loan amount.

Pros Cons
Topping up is relatively simple if you stick with the same lender. You’re restricted by your current lender’s terms and conditions.
Avoids many fees associated with refinancing, like application or exit fees. You need enough equity in your home to qualify.
Since the funds are added to your mortgage, you benefit from the typically lower interest rates of home loans compared to personal loans or credit cards.  

A top-up is ideal if you’re happy with your current lender and need a relatively small to medium amount for renovations.

2. Refinance Your Mortgage

Refinancing means swapping your current loan for a new one. It’s a great way to secure a better interest rate, adjust your loan terms, or borrow more for your renovations. It’s especially helpful for larger projects or combining debts into one loan.

When you refinance, you pay off your current loan and take out a new one, potentially with a different lender. As part of the refinancing process, you can increase the loan amount to access funds for renovations.

Example:
If your interest rate isn’t competitive and you need $100,000 for a second-story extension, refinancing can provide the funds while possibly lowering your interest rate or adjusting your loan to make repayments easier.

Pros Cons
It can help you get a lower interest rate, saving you money over time. It may come with fees, like exit costs for your old loan and charges for the new loan’s application or valuation.
Ideal for significant renovations or home upgrades. Refinancing involves more paperwork and a longer approval process compared to a top-up.
Refinancing allows you to shop around for a lender that best suits your needs.  

Refinancing is a smart choice if you’re planning major renovations, want to improve your loan terms, or have already explored and ruled out a top-up option.

3. Construction Loans

If your renovation plans involve large-scale projects like adding a new floor, building an extension, or major structural changes, a construction loan could be the right solution. These loans are specifically designed for renovation or building projects and provide funds in stages as the work progresses.

Construction loans work differently from traditional loans. The total loan amount is pre-approved based on the renovation plans and quotes you provide. However, the funds aren’t released all at once. Instead, they’re disbursed in stages, such as after the foundation or framing is done.

Example:
If you’re building a second story, the first portion of funds might be released once the foundation is laid, the second after framing, and so on. This ensures funds are used effectively and align with the project’s progress.

Pros Cons
Designed specifically for significant renovations or rebuilds. The application process is more detailed and requires thorough documentation, including quotes and plans from builders.
Funds are released as needed, reducing the temptation to overspend. Some lenders may charge higher rates for construction loans compared to standard home loans.
Loan terms are structured to accommodate the unique requirements of construction projects.  

Construction loans are ideal for homeowners tackling major renovations or rebuilds that require staged funding and close coordination with contractors.

How to Choose the Right Option

Choosing the best borrowing option depends on factors like the scale of your renovation, your financial situation, and your goals:

  • Top-Up Your Mortgage if you need a straightforward, cost-effective way to access a moderate amount of funds.
  • Refinance Your Mortgage if you’re planning larger projects and want to improve your loan terms.
  • Opt for a Construction Loan if your project involves significant structural changes or staged progress.

Each option has pros and cons. A good mortgage broker can guide you through your choices and help you find the best fit for your needs.

Tips for Borrowing Smartly

Smart borrowing can make your renovation journey smoother and stress-free. Here are some key tips to ensure you’re making the best financial decisions while staying on track.

Seek Professional Guidance

Mortgage brokers in Sydney can save you time, money, and stress. They work with multiple lenders to find options that match your needs and guide you through the loan process. For example, they might help you secure a renovation loan with a lower rate you wouldn’t have found on your own.

Set a Realistic Budget

Creating a budget keeps your renovation on track. Start by getting quotes from contractors, estimating material costs, and adding fees for permits or approvals. Always include a 10–20% buffer for unexpected surprises like hidden plumbing issues. For example, if your budget is $40,000, set aside $4,000–$8,000 extra for contingencies.

Compare Loan Options and Lenders

Lenders can differ widely in terms, rates, and fees, so shopping around is crucial. A little difference in interest rates could save you thousands over time. For example, one lender might have a lower rate but higher exit fees, while another offers better repayment flexibility. A broker can simplify this comparison for you.

Think About the Long-Term Impact

Borrowing extra money will increase your loan repayments, so it’s important to consider how this fits into your long-term financial plans. Use a mortgage calculator to estimate how an additional loan amount will affect your monthly payments. For example, if a $50,000 top-up increases your repayments by $200 per month, ensure this adjustment is sustainable within your budget. Also, consider whether the renovations will add enough value to your home if you plan to sell in the future.

Avoid overcapitalising

Spending more on renovations than your home’s value can support is a common mistake. Research property values in your area and focus on improvements that will maximise your home’s marketability. For instance, upgrading a kitchen or bathroom is often a safer bet than investing in high-end finishes that may not appeal to buyers in your neighbourhood. Consulting with a real estate agent or valuer can provide valuable insight into the best renovations for boosting your home’s value.

Understand Loan Terms and Fees

Before committing to a loan, take time to understand the associated costs. Fees like application charges, valuation fees, and account-keeping costs can quickly add up. Compare the overall cost of loans. For example, one with a slightly higher interest rate but no upfront fees might be cheaper than a low-rate loan with high fees.

Plan for Potential Interest Rate Changes

If you’re opting for a variable-rate loan, it’s wise to prepare for possible rate increases. Calculate how your repayments might change if rates rise and ensure this won’t strain your budget. For instance, if your repayments are $1,200 per month at a 5% rate, plan for what they would look like at 6%. If you prefer stability, consider splitting your loan between fixed and variable rates.

Monitor Your Renovation Costs

Once you’ve secured the funds, stay on top of your expenses during the renovation. Use spreadsheets or budgeting apps to track costs and make adjustments if needed. Regularly check with your contractor to ensure the work is on schedule and stays within your budget. This can help you avoid surprises and keep things running smoothly.

When Borrowing Might Not Be the Best Option

Borrowing extra isn’t always the answer. If your renovations are minor or your debt-to-income ratio is already stretched, it might be smarter to save up or explore smaller loan options. Similarly, if you’re close to paying off your mortgage, adding more debt might not align with your long-term goals.

Renovate with Confidence

Borrowing extra through your mortgage is a smart way to fund renovations, often at a lower interest rate than other loans. With careful planning and expert guidance from Unconditional Finance, you can enhance your home without overextending your finances.
