Should you manage your investment property?

Renovating an investment property can be a smart way to attract quality tenants, increase rental income and potentially boost your property’s value. Whether you’re planning a simple cosmetic refresh or a major structural upgrade, having the right finance strategy in place is just as important as choosing the right renovations.
Many property investors focus on renovation costs but don’t always consider how their funding choice could affect cash flow, borrowing capacity and long-term financial goals. Fortunately, there are several finance options available depending on the size of your project and your circumstances.


If you’re planning smaller cosmetic improvements, such as repainting, replacing flooring or updating window furnishings, a personal loan may be an option.
Unsecured personal loans don’t require your property as security, and you’ll generally know your loan amount, repayments and loan term upfront. This can make budgeting straightforward.
However, personal loans often come with higher interest rates than home loans, and repayment terms are usually much shorter, typically between one and seven years. While you’ll pay the loan off sooner, your monthly repayments may be significantly higher.
If your investment property has increased in value or you’ve built up equity by paying down your mortgage, refinancing could allow you to access that equity to fund your renovation.
Equity is the difference between your property’s current market value and the remaining balance on your home loan.
One of the main advantages of refinancing is that home loan interest rates are generally lower than personal loan rates. This can make refinancing an attractive option for larger renovation projects. Keep in mind, however, that you’re increasing the amount you owe on your mortgage, so it’s important to ensure the repayments remain affordable.
Another option is increasing the balance of your existing home loan through a loan top-up.
Rather than taking out a separate loan, your lender adds additional funds to your current mortgage, allowing you to finance your renovation under the same loan.
A top-up loan often provides access to lower interest rates than a personal loan or credit card, and because you’re using your existing mortgage, setup costs may be lower than refinancing to a new lender. The approval process can also be simpler.
Most lenders will generally allow you to borrow up to 80% of your property’s value before lenders mortgage insurance (LMI) may apply. It’s also worth remembering that spreading renovation costs over the life of your mortgage could mean paying more interest overall.
If you’re undertaking a significant renovation involving structural work, extensions or major rebuilding, a construction loan may be worth considering.
Construction loans release funds progressively as your builder completes agreed stages of the project. Depending on your loan structure, you may only pay interest on the amount that has been drawn down, rather than the full approved loan amount.
This can help ease cash flow during the build. However, construction loans may have slightly higher interest rates and usually require additional documentation, including building contracts, plans and council approvals where applicable.
A line of credit allows you to access the equity in your property and withdraw funds when you need them, up to an approved limit.
Because you’re able to draw funds progressively, some investors find this option useful for renovation projects where expenses occur over time rather than all at once.
Interest is generally only charged on the amount you’ve used, not your full credit limit. However, because your property secures the facility, it’s important to borrow carefully and ensure you can comfortably meet your repayments.
If you’ve built up savings or accumulated funds in an offset account or redraw facility, using your own money may be the simplest financing option.
Paying with existing funds means you won’t need to increase your debt or pay additional interest. It’s also wise to leave a financial buffer for unexpected expenses, as renovation projects don’t always go exactly to plan.
The right finance solution depends on your renovation goals, budget, available equity and long-term investment strategy. What works well for a small cosmetic update may not be the best approach for a large-scale renovation.
Understanding your options before work begins can help you avoid unnecessary costs and ensure your renovation supports your broader financial goals.
The right finance solution can help you complete your renovation with confidence while supporting your long-term investment goals. Whether you’re planning a simple cosmetic upgrade or a major renovation, getting the right advice before you begin can make all the difference.
