Renovating an investment property can help attract quality tenants, improve rental returns and potentially add value. But before you choose paint colours or start collecting quotes, it is worth understanding how you will fund the project.
The renovation is only half the decision. How you fund it shapes your cash flow, your borrowing capacity and the total cost over the life of the loan.
Many investors focus on the renovation itself and overlook the impact of their funding choice. The good news is that there are several ways to finance one, from accessing equity to topping up an existing home loan. Here is what to know before you get started.
Personal Loan
Say you want a few cosmetic enhancements. Nothing too major, perhaps a paint job, some new window dressings and updated flooring. For a small project, a personal loan might be worth considering. Unsecured personal loans do not use your property as security, and the loan amount and repayment term are generally set when the loan is established.
The trade-off is cost. Interest rates are often higher than those on home loans, and terms are generally shorter, often one to seven years, which can mean higher monthly repayments.
Refinancing
If your property's value has risen or you have paid down your mortgage, you may be able to refinance and use the equity to fund your renovation. Equity is the difference between the current market value of your property and what you still owe.
The advantage here is that rates are lower than for a personal loan, so for a major renovation it can be worth exploring. Just keep in mind you are adding more debt to your mortgage, so the numbers need to stack up over the longer term.
Top-Up Loan
Another option is to top up your existing loan. A top-up is an extension of your current mortgage that lets you borrow extra without opening a whole new loan, with the lender adding the new funds to your balance. Like refinancing, it gives you access to lower rates than a personal loan or credit card, you will usually avoid the setup fees of a new loan, and approval is generally simpler than a full refinance.
It is worth remembering that lenders will usually only let you borrow up to 80% of your property's value. Beyond that, you may be up for Lenders' Mortgage Insurance, and because you are spreading the renovation cost over the life of the loan, you could pay more interest in the long run.
Construction Loan
For larger projects, such as structural changes, you might consider a construction loan. With this type of finance, the lender releases money in stages as your builder reaches agreed milestones. Depending on the structure, you may only pay interest on the funds that have been drawn, and many lenders offer interest-only payments during the build, which can help you manage cash flow.
The trade-offs are that rates can be slightly higher, and there is usually more paperwork involved, such as building plans and contracts.
Line Of Credit
A line of credit lets you access the equity in your property and draw funds as needed, up to an approved limit. Because you can access money when required rather than all at once, some investors use it to fund renovation projects in stages. Interest is generally charged only on the amount you have drawn, not the full limit.
The flexibility is useful, but because the facility is secured against your property, it is important to borrow responsibly and be confident you can manage the repayments. If you cannot meet your obligations, your property could be at risk.
Use Existing Funds
If you have savings, or money sitting in an offset account or redraw facility, you might decide to use those funds for your renovation. Just remember it is always sensible to keep a little aside for cost overruns.
The right choice depends on the size of the job and what you are trying to achieve. If the goal is a stronger yield, it is worth weighing the finance cost against the likely lift in rent, which we cover in why investors are focusing on rental income.

Fund The Reno Before You Start It
Renovating can be exciting, but understanding your finance options before you commit is what keeps the project from quietly eating into your returns. Reach out and we will talk through your circumstances and the options that might suit your situation.
