Cash flow relief of $20,000+ redirected to offsets, other mortgages or the next deposit

You've signed the build contract and settled the land. The property won't be complete for nine to twelve months. In a standard construction loan, repayments begin climbing from the moment the first progress draw is made. If you're still paying rent, or carrying an existing owner-occupier mortgage, that overlap puts real pressure on your cash flow month after month.

This post looks at one specific question: what can you actually do with the cash that HomePay frees up during the construction period?

How the cash flow relief works

HomePay is a Build Now Pay Later finance product. HomePay loans pause out-of-pocket repayments on both the land and construction loan, covering the full twelve-month construction period. Any interest accrued during that period is simply added to your loan balance and repaid over the remaining loan term. Once construction is complete, standard mortgage repayments begin after the twelve-month pause finishes.

It is not an interest-only arrangement, and the deferred interest does get added to your principal. That is worth understanding clearly before you structure anything around the freed-up cash.

At the time of writing, the average new owner-occupier loan in Australia sits at approximately $730,720, with an average initial monthly repayment of around $4,494 over a thirty-year term (per money.com.au, updated August 2026). On an investment property loan, investor outstanding rates run roughly 0.2 to 0.3 percentage points above comparable owner-occupier rates, per the APRA/RBA F6 series. Across a twelve-month build, the cash not leaving your account each month could easily total $20,000 or more, depending on your loan size and rate at the time.

The key question is not just how much is freed up. It is where does it go during those twelve months to make a meaningful difference.

Three places the freed cash can go

1. Into an offset account against your existing mortgage

If you already hold a home loan on your primary residence, parking the freed cash in an offset account linked to that loan reduces the daily interest calculation straight away. An offset account is a transaction account linked to your home loan; the balance is offset against your loan when the bank calculates interest each day, so you pay less interest rather than earning interest on the offset funds.

The tax angle matters here. Interest earned on a savings account is assessable income, taxed at your marginal rate. If you earn $100,000 per year, you pay 37% tax on savings interest. The interest saved through an offset account carries no equivalent tax cost, because you are not earning income, you are simply reducing a charge. For someone in the 30% or higher marginal tax bracket, the after-tax benefit of an offset account is roughly twice the after-tax interest you would earn on a savings account. How an offset arrangement applies to your specific loan and tax situation is something to confirm with a licensed broker and your accountant.

A $50,000 offset balance on a $600,000 loan over thirty years typically saves around $130,000 to $160,000 in total interest and shortens the loan by three to five years compared to no offset, based on current rate environments (per freefincalc.net, April 2026). These are illustrative figures, not a projection of your outcome.

2. Directed toward extra repayments on an existing mortgage

For investors who hold other loans without offset functionality, making additional principal payments during the construction period reduces the balance those loans are charging interest against. The compounding effect of earlier principal reduction is significant over a thirty-year term. A licensed broker can model the actual numbers for your loan structure.

3. Held as the foundation of a next deposit

For buyers building their first investment property, the twelve-month window is a genuine opportunity to begin accumulating the deposit for a second property. Almost 3.3 million Australian households carry a mortgage, and Australians held about $349.1 billion in offset accounts as of March 2026, per ASIC. The discipline of treating freed repayments as capital rather than discretionary spending is what separates a one-property portfolio from a two-property one.

A worked example

Consider an investor buying a house-and-land package with a combined loan (land plus construction) of $650,000. At a rate of, say, 6.5% per annum at the time of writing, a standard principal-and-interest repayment on that amount over thirty years would be roughly $4,100 per month.

Under HomePay, that $4,100 per month stays in the investor's account during construction. Over twelve months, that is approximately $49,200 sitting elsewhere rather than being paid to the lender.

Now consider that same investor holds an existing owner-occupier loan with a $500,000 balance and an offset account. Parking $40,000 of that $49,200 into the offset account during the construction phase reduces the interest charged on the owner-occupier loan by approximately $2,600 per year (at a 6.5% rate, illustrative only). The remaining $9,200 begins building toward a future deposit.

Those numbers will differ depending on your loan size, rate, and structure at the time. The principle, however, is consistent: freed-up cash is most effective when it is directed intentionally, not left sitting in a transaction account earning little while interest accrues on other debts.

Interest on the deferred HomePay period does capitalise onto your loan balance. Factor that into your overall numbers, not just the short-term cash benefit.

What to think about before acting

A few things are worth understanding clearly before structuring anything around HomePay cash flow relief:

• The deferred interest. The twelve months of paused repayments are not free months. Interest accrues and is added to the loan principal. Your repayments from month thirteen are calculated on a slightly higher balance. Understand the full loan cost, not just the construction-phase savings.
• Offset account suitability. Home loans with offset accounts typically carry a slightly higher interest rate than basic variable loans without an offset feature. Whether the offset benefit outweighs the rate difference depends on how much you hold in the account and for how long. A broker can run this comparison for your situation.
• Investment loan deductibility. For investment properties, the treatment of interest expenses, including capitalised interest, is a tax matter. This is something to discuss with a registered tax agent or accountant, not something EWC advises on.
• Builder accreditation. HomePay requires the builder to be accredited under their framework. Not every builder qualifies. This is one of the first things to confirm when sourcing a property through EWC.

Next steps

1. Talk to an EWC property coordinator. We source investment properties and house-and-land packages from accredited HomePay builders. See the full range of what we do at /services. To start a conversation, book a free call at https://elitewealthcreators.com/booking/.

2. Get a broker to model your specific numbers. A licensed mortgage broker can compare the HomePay structure against standard construction finance for your loan size, run offset account projections against your existing debts, and assess your borrowing capacity across both loans. EWC connects clients with brokers experienced in investment and construction lending.

3. Speak with your accountant about the tax picture. The deductibility of interest on an investment construction loan, the treatment of capitalised interest, and the implications for your existing offset account are all questions for a registered tax agent, not a property coordinator. Getting clarity on this before settlement avoids surprises at tax time.
