DHOAS can make buying an investment-grade home in Australia more affordable, but the real cost is more than the interest rate. How much do DHOAS loans cost comes down to the loan type, lender fees, ongoing charges, and how the subsidy is applied over time.

This guide breaks down the costs property investors should check before they commit, especially if they are building or managing a portfolio.

What is a DHOAS loan, and why does cost vary so much?

A DHOAS loan is a home loan eligible for the Defence Home Ownership Assistance Scheme subsidy, paid monthly towards interest. How much do DHOAS loans cost varies because lenders price DHOAS products differently, and the subsidy does not remove fees.

Two people can borrow the same amount and receive the same subsidy, but still pay different totals due to rate margins, loan features, and package costs.

What are the upfront costs when taking out a DHOAS loan?

Upfront costs usually include lender establishment fees, government charges, and settlement-related costs. How much do DHOAS loans cost at the start often surprises borrowers because DHOAS does not cover these items.

Common upfront costs in Australia include:

• Application or establishment fee
• Valuation fee (sometimes waived)
• Settlement fee
• Lenders Mortgage Insurance (if applicable)
• State or territory stamp duty (unless exempt)
• Conveyancing or solicitor fees

Do DHOAS borrowers pay higher interest rates than standard loans?

Sometimes they do, and sometimes they do not. How much do DHOAS loans cost in interest depends on whether the lender’s DHOAS product is priced competitively and whether the borrower qualifies for sharper rates elsewhere.

Some DHOAS loans carry a slight premium because of administration and product design. Others are priced close to standard owner-occupier loans, especially when lenders compete for Defence customers.

How does the DHOAS subsidy reduce the real cost of the loan?

The subsidy reduces monthly interest out of pocket, not the interest charged by the lender. How much do DHOAS loans cost therefore needs two views: the lender’s repayment schedule and the borrower’s net repayment after subsidy.

For portfolio planning, investors should model cash flow with and without the subsidy. The subsidy can improve serviceability and buffer holding costs, but it is not guaranteed forever if eligibility changes.

What ongoing fees should investors expect with DHOAS loans?

Ongoing fees can materially change the total cost over years. How much do DHOAS loans cost is often driven by annual package fees and monthly account charges, not just the headline rate.

Typical ongoing fees include:

• Monthly account-keeping fee
• Annual package fee (for offset and discounts)
• Offset account fee (sometimes included)
• Redraw fees (less common now)
• Loan service fees for certain actions

Even a modest annual fee can outweigh a small interest-rate discount, particularly on smaller balances or when the loan is paid down quickly.

Are offset accounts and redraw features worth paying for?

They can be, but only when used strategically. How much do DHOAS loans cost can rise if borrowers pay for features they do not use, especially package loans with annual fees.

For investors managing cash flow, an offset can be valuable for holding buffers, timing repairs, and managing vacancy periods. Redraw can help too, but it may complicate record-keeping if funds are mixed between personal and investment purposes. They should get tax advice specific to their situation in Australia.

What are the costs of refinancing a DHOAS loan later?

Refinancing can reduce interest but still carry switching costs. How much do DHOAS loans cost over the full life can increase if borrowers refinance repeatedly without a clear net benefit.

Refinancing costs may include:

• Discharge fee from the current lender
• New application and settlement fees
• New valuation fees
• Government registration fees
• Potential break costs on fixed rates

Investors should compare the total savings against these costs, and also confirm DHOAS subsidy continuity when changing lenders.

Do fixed-rate DHOAS loans cost more than variable-rate options?

Fixed rates can be cheaper or more expensive depending on the market cycle, but they may add risk through break costs. How much do DHOAS loans cost on a fixed term is usually clearer month to month, yet costly if the borrower exits early.

For investors, fixed rates can stabilise holding costs, which helps when rents shift or expenses rise. Variable rates can suit those who prioritise extra repayments, refinancing flexibility, or active debt recycling strategies.

How much do DHOAS loans cost if Lenders Mortgage Insurance applies?

If the deposit is small, LMI can be one of the biggest single costs. How much do DHOAS loans cost increases sharply when borrowing above 80% of the property value, depending on lender policy and borrower profile.

LMI is typically capitalised into the loan, which means interest is charged on it. Investors should quantify the long-term cost of that added balance, not just the upfront premium.

Are there hidden costs in DHOAS eligibility and administration?

The scheme itself is not the hidden-cost problem, but delays and admin friction can create indirect costs. How much do DHOAS loans cost can rise if settlement is delayed and the borrower pays extension fees, bridging costs, or loses a rate lock.

They should allow time for eligibility confirmation, lender DHOAS processes, and Defence-related paperwork. Good preparation reduces the chance of paying for rushed valuations, urgent legal work, or contract changes.

How can property investors estimate the true cost of a DHOAS loan?

They should calculate total costs over the intended hold period, not just compare advertised rates. How much do DHOAS loans cost becomes clear when they model net repayments, fees, and realistic scenarios such as rate rises and vacancy.

A practical approach is to compare:

• Interest rate and comparison rate
• Total fees over 1, 3, and 5 years
• Expected subsidy over those same periods
• Refinancing costs if they plan to switch
• Buffer needs for portfolio risk

This is where experienced mortgage advice and buyer-side planning can prevent costly mismatches between finance structure and investment strategy. Check out more about comparing your options for HPAS specialist.

What questions should they ask a lender or broker before signing?

They should ask for a full cost breakdown in writing and confirm exactly how the subsidy is applied. How much do DHOAS loans cost is easiest to control when they pressure-test the loan against their portfolio goals.

Key questions include:

• What are all upfront and ongoing fees for this specific product?
• Is there an annual package fee, and what does it include?
• Are offset and redraw included, and what are the conditions?
• Can they split the loan, and are there fees to do so?
• What are fixed-rate break costs likely to look like?
• How will the DHOAS subsidy be paid and shown on statements?
• What happens to pricing if their circumstances change?

What is the bottom line on DHOAS loan costs in Australia?

The bottom line is that the subsidy can materially reduce net interest, but fees, features, and loan structure still drive the total cost. How much do DHOAS loans cost is best answered by modelling the loan like an investor, with clear timeframes and worst-case assumptions.

When they treat DHOAS as one part of a broader portfolio plan, they are more likely to choose a loan that supports long-term outcomes rather than simply looking cheaper on day one.
