Step-by-Step Guide Using Home Equity to Buy Another House

Table of Contents

In Australia, the concept of using home equity to buy another house has become increasingly popular among homeowners looking to expand their property portfolios. Whether you’re considering an investment property, a holiday home, or even helping a family member get on the property ladder, leveraging the equity in your current home can be a smart financial move. This guide will walk you through the process step-by-step, ensuring you understand each stage and make informed decisions along the way.

What is Home Equity?

Home equity is the difference between your home’s current market value and the remaining mortgage balance. In essence, it’s the part of the property that you genuinely possess. For example, if your home is valued at $900,000 and you owe a mortgage of $400,000, your home equity would be $500,000.

Calculating your home equity is straightforward:

  • Determine Your Home’s Market Value: This can be done through a professional appraisal, a real estate agent’s assessment, or online property value estimators.
  • Subtract Your Mortgage Balance: Check your latest mortgage statement for the outstanding loan balance.
  • Result: The remaining figure is your home equity.

Understanding your home equity is crucial as it determines your borrowing power when you plan to use it for purchasing another property.

Why Use Home Equity to Buy Another House?

Using home equity to buy another house provides numerous advantages, making it an attractive option for homeowners. Here are some of the primary reasons why you might consider this strategy:

Financial Leverage

Leveraging your home equity can provide you with a substantial amount of capital without the need to liquidate other investments or save up for a new down payment. This financial leverage can help you take advantage of investment opportunities as they arise.

Potential for Investment Growth

Investing in property has long been a popular strategy for wealth creation in Australia. By using your home equity to buy another house, you can benefit from potential property value appreciation and rental income, thereby enhancing your overall financial portfolio.

Tax Advantages

In some cases, the interest paid on a home equity loan or line of credit used for buying an investment property can be tax-deductible. It’s advisable to consult a tax professional to determine how these benefits might apply to your individual circumstances.


Owning multiple properties can diversify your investment portfolio, reducing risk. For example, if one property market experiences a downturn, the other might remain stable or even appreciate, balancing out potential losses.

Helping Family Members

For those looking to assist family members, such as first home buyers, using home equity can provide the necessary funds without dipping into savings or other investments. This approach can make it easier for your loved ones to enter the property market.

Using home equity to buy another house is not without risks and considerations, which we will explore further in this guide. However, with professional advice and careful planning, it can be a highly effective strategy to grow your property portfolio and achieve your financial goals.

Step 1: Assessing Your Home Equity

The first step in using home equity to buy another house is to accurately assess your current home equity. This involves determining the market value of your home and subtracting any outstanding mortgage balance. It’s beneficial to obtain a professional appraisal or consult with a real estate agent to get a precise valuation. Accurate assessment is crucial, as it lays the foundation for understanding how much equity you can potentially leverage for your new home purchase.

Step 2: Understanding Your Borrowing Power

Once you know your home equity, the next step is to understand your borrowing power. Lenders will assess your equity, income, credit history, and overall financial situation to determine how much they are willing to lend. Typically, you can borrow up to 80% of your home’s appraised value, minus any existing mortgage balance. Understanding your borrowing power helps you set a realistic budget for purchasing your second property.

Step 3: Choosing the Right Financing Option

When using home equity to buy another house, you’ll need to decide between a home equity loan and a home equity line of credit (HELOC). A home equity loan provides a lump sum at a fixed interest rate, ideal for those who prefer predictable payments. A HELOC, on the other hand, offers more flexibility with a revolving credit line, allowing you to draw funds as needed. Each option has its pros and cons, so it’s essential to choose the one that aligns best with your financial goals and situation.

Step 4: Preparing Your Finances

Before applying for a loan, it’s important to prepare your finances to ensure you meet the lender’s requirements. Start by improving your credit score, paying down existing debts, and ensuring you have all necessary documentation, such as proof of income and detailed records of your financial assets. Proper preparation can significantly enhance your chances of loan approval and potentially secure better loan terms.

Step 5: Applying for a Home Equity Loan or HELOC

With your finances in order, you can proceed to apply for a home equity loan or HELOC. This involves submitting an application to your chosen lender, who will evaluate your equity, creditworthiness, and overall financial health. Be prepared to provide comprehensive documentation and answer any questions the lender might have. Once approved, you’ll receive the funds needed to make your new home purchase, allowing you to move forward with confidence in your investment decision.

Step 6: Finding the Right Property

Once your financing is secured, the next step is to find the right property. Consider your goals, whether it’s for investment purposes, a holiday home, or another residence. Evaluate potential properties based on location, market trends, and rental yield if applicable. Working with a reputable real estate agent can provide valuable insights and help you identify properties that align with your objectives. Thorough research and due diligence are essential to ensure you make a sound investment decision.

Step 7: Making the Purchase

With a property in mind, it’s time to make the purchase. This involves negotiating the sale price, conducting inspections, and finalising the purchase agreement. Engaging a solicitor or conveyancer is crucial to navigate the legal aspects and ensure a smooth transaction. Once all conditions are met and the contract is signed, you’ll proceed to settlement, where the funds from your home equity loan or HELOC will be used to complete the purchase. At this point, you officially become the owner of your new property.

Step 8: Managing Your Investment

Effective management of your new property is key to maximising its value and achieving your financial goals. If it’s an investment property, consider hiring a property manager to handle tenant relations, maintenance, and rent collection. Regular maintenance and timely upgrades can enhance property value and rental income. Keeping detailed records and monitoring your investment’s performance will help you make informed decisions and ensure the long-term success of using home equity to buy another house.

Common Pitfalls to Avoid

When using home equity to buy another house, it’s crucial to be aware of common pitfalls that could undermine your financial goals. Below are some key areas to watch out for, along with strategies to avoid them.

1. Overleveraging Your Home Equity

One of the biggest mistakes homeowners make is overleveraging their home equity. While it may be tempting to borrow the maximum available amount, doing so can lead to financial strain if property values decline or interest rates rise. To avoid this, it’s wise to borrow conservatively and leave a financial buffer to accommodate potential market fluctuations.

2. Insufficient Due Diligence on the New Property

Neglecting to carry out comprehensive due diligence on the new property can lead to unexpected problems and costs. Always ensure comprehensive property inspections are carried out, covering structural integrity, pest inspections, and compliance with local regulations. Research the local market conditions, future development plans, and neighbourhood amenities to ensure the property meets your investment criteria and long-term goals.

3. Underestimating Additional Costs

Many buyers overlook the additional costs associated with purchasing and maintaining a new property. These can include property taxes, insurance, maintenance, and potential renovation expenses. To prevent being caught off guard, create a detailed budget that accounts for all possible costs and ensures you have sufficient funds set aside.

4. Ignoring Cash Flow Management

When using home equity to buy another house, effective cash flow management is essential. If the new property is an investment, consider how rental income will cover mortgage payments, maintenance, and other expenses. Ensure you have a plan for periods of vacancy and unexpected repairs. Sustaining a positive cash flow is critical to sustaining your investment over the long term.

5. Lack of Professional Advice

Attempting to navigate the complexities of using home equity without professional advice can lead to costly mistakes. Engaging with a financial advisor, mortgage broker, real estate agent, and solicitor can provide invaluable insights and help you make informed decisions. These professionals can guide you through the process, highlight potential risks, and suggest strategies tailored to your financial situation.

6. Overlooking Market Conditions

Ignoring current and future market conditions can impact the success of your investment. It’s important to stay informed about property market trends, interest rate forecasts, and economic factors that could influence property values and rental demand. Adjust your investment strategy based on market insights to maximise your returns and minimise risks.

7. Inadequate Planning for Loan Repayments

Taking on additional debt without a solid repayment plan can jeopardise your financial health. Ensure you have a clear strategy for repaying the home equity loan or HELOC, considering both best-case and worst-case scenarios. Factor in potential changes in interest rates and personal circumstances that could affect your ability to make repayments.


Using home equity to buy another house can be a strategic way to expand your property portfolio and achieve your financial goals. By following the steps outlined in this guide—assessing your home equity, understanding your borrowing power, choosing the right financing option, preparing your finances, applying for a loan, finding the right property, making the purchase, and managing your investment—you can navigate the process with confidence. Remember to be mindful of common pitfalls and ask for professional advice to ensure a successful investment. With careful planning and informed decisions, leveraging your home equity can open new opportunities for growth and financial stability in the Australian property market.

Frequently Asked Questions

Is it a good idea to use equity to buy another property?

Using home equity to buy another property can be a good idea if done strategically. It allows you to leverage the value of your existing home to invest in additional property, potentially increasing your wealth through property appreciation and rental income. However, it’s essential to consider the risks, such as market fluctuations, interest rate changes, and your ability to manage additional debt. Consulting with financial advisors and thoroughly assessing your financial situation is crucial before making this decision.

Can I buy another house with two houses and their equity without a deposit?

Yes, it is possible to buy another house using the combined equity of two houses without a traditional cash deposit. Lenders may allow you to use the equity from both properties as collateral for the new loan. This strategy can help you avoid the need for a cash deposit, but it’s important to ensure that you do not overleverage yourself and that you can comfortably handle the repayments on the new loan.

How Do You Use Equity in an Existing House?

Using equity in an existing house typically involves applying for a home equity loan or a home equity line of credit (HELOC). Here’s a brief overview of the process:

  1. Assess Your Home Equity: Identify the current market value of your house and subtract the outstanding mortgage balance.
  2. Apply for a Loan: Contact your lender for your application of home equity loan or HELOC. Submit the required documents, such as credit history, proof of income, and information about your current mortgage.
  3. Approval and Funds: Once approved, you can access the loan amount or credit line to finance the purchase of another property.

Can You Borrow Money Against Your House if You Own It Outright?

Yes, if you own your house outright, you can borrow money against it. This is often referred to as a home equity loan or a cash-out refinance. Since there is no existing mortgage, the equity in your home is equivalent to its full market value. Lenders may offer favourable terms because the property can serve as collateral. This option can provide a significant amount of capital for various purposes, including buying another house.
