First Home Buyer LMI Saving Calculator: $700K Property = $20–25K Saved

Introduction

For an eligible first home buyer in Australia, Lenders Mortgage Insurance (LMI) has long been the largest single friction cost beyond the deposit itself. A property priced at $700,000 – a realistic entry point for a unit in many capital cities – can attract an LMI premium of $20,000 to $25,000 when the borrower lacks a 20 per cent deposit. The Australian Government’s Home Guarantee Scheme, and specifically the First Home Guarantee (FHBG), removes that premium entirely for approved applicants purchasing with as little as a 5 per cent deposit. This article quantifies the saving and links it to the 2026 policy settings that make the benefit available. All figures are presented for informational purposes; no personal financial advice is given.

How Lenders Mortgage Insurance Works in Australia

LMI is a single-premium policy that protects the lender, not the borrower. It is triggered whenever a residential loan’s loan-to-valuation ratio (LVR) exceeds 80 per cent. The cost is almost always passed through to the borrower, either as a lump sum at settlement or capitalised into the loan balance, where it accrues interest for the full loan term.

APRA’s quarterly Authorised Deposit-taking Institution Property Exposures statistics confirm the prevalence of high-LVR lending. In the December 2025 quarter, 21.3 per cent of new owner-occupier loans were written at an LVR above 90 per cent, a cohort that routinely incurs LMI (APRA, Quarterly ADI Property Exposures). The premium itself scales with the dollar amount of the loan, the LVR band, and the lender’s arrangement with the mortgage insurer. Industry premium schedules, such as those published by Genworth Australia and QBE, place a 95 per cent LVR owner-occupier loan in a band that attracts a premium of approximately 3.0 to 3.5 per cent of the loan amount before stamp duty on the premium.

For a $665,000 loan – the 95 per cent portion of a $700,000 purchase – that translates to a debit of roughly $19,950 to $23,275. When capitalised, the ongoing interest on the premium adds further cost, pushing the effective lifetime expense above $25,000 in many scenarios. Avoiding LMI therefore represents a material preservation of equity for a first home buyer.

The First Home Guarantee and LMI Waiver

The First Home Guarantee is administered by Housing Australia (formerly the National Housing Finance and Investment Corporation, NHFIC). The scheme allows an eligible first home buyer to acquire a qualifying property with a deposit of as little as 5 per cent. Housing Australia guarantees to the lender the remaining shortfall up to 15 per cent of the property’s value. Because the lender now holds a loan effectively at an 80 per cent LVR, LMI is not required.

The mechanism is not a grant or a rebate. Instead, it shifts the risk from the lender to the Commonwealth balance sheet, eliminating the insurer’s premium altogether. An applicant who would otherwise pay $22,000 in LMI on a $700,000 purchase pays zero dollars, while the lender accepts the insured risk position without charging the borrower (Housing Australia, Home Guarantee Scheme Overview).

2026: Scheme Capacity and Budget Commitment

Sustainable availability of the LMI saving through 2026 is underpinned by explicit Government funding. The 2025–26 Federal Budget committed to 50,000 First Home Guarantee places for the financial year, an increase from 35,000 places allocated in 2024–25 (Australian Government, Budget 2025–26: Housing). Forward estimates in the same budget papers confirm the scheme will continue with comparable allocations into 2026–27, providing first home buyers with a clear line of sight to a fee-free LMI outcome well into 2026.

The enlarged cap is essential because demand exceeded available places in several earlier periods. For buyers planning a purchase in 2026, the 50,000-place ceiling means the FHBG remains a viable planning assumption, but it also means early application is prudent once a suitable property is identified.

Running the Numbers: $700,000 Property Scenario

The saving is best illustrated by a concrete example. Assume a first home buyer is targeting a dwelling priced at $700,000 – a sum close to the mean first-unit price in Brisbane or Adelaide, and still below the scheme’s price caps in those capitals. The buyer has saved a 5 per cent deposit of $35,000. Under a conventional loan, the borrower would seek a $665,000 mortgage at 95 per cent LVR. Based on the premium bands noted above, the LMI estimate sits at $21,945, which when capitalised yields a final loan balance of around $686,945 and adds approximately $2,800 in interest over the first five years alone.

Under the FHBG, the same $35,000 deposit secures a $665,000 loan. Housing Australia guarantees 15 per cent, the lender treats the LVR as 80 per cent, and no LMI is payable. The immediate cash saving is $21,945. When the carrying cost of the capitalised premium is included, the effective lifetime benefit routinely exceeds $25,000. The buyer retains a higher equity position from settlement day and reduces the interest expense on the premium forever.

A quick comparison across other deposit levels further demonstrates the policy’s value at low equity:

• 10 per cent deposit ($70,000), 90 per cent LVR loan of $630,000: LMI estimated at $13,860, still avoided via the FHBG.
• 15 per cent deposit ($105,000), 85 per cent LVR loan of $595,000: LMI estimated at $7,000, again avoided.
• 20 per cent deposit ($140,000): LMI not required anyway; the scheme’s edge is the ability to enter the market with a smaller deposit while preserving capital.

The headline saving of $20,000–$25,000 is therefore the 5 per cent deposit case, which is precisely the minimum the scheme permits.

Eligibility and Application Process

To access the LMI saving, a buyer must be an Australian citizen or permanent resident, be at least 18 years old, and not have previously owned or held an interest in residential property in Australia. Income caps apply: $125,000 for singles and $200,000 for couples in the 2025–26 year. The property price cap varies by state and by whether the property is in a capital city or regional centre. For 2025–26, the cap for a capital city unit is typically around $800,000 in Brisbane, $900,000 in Melbourne and $950,000 in Sydney, ensuring a $700,000 purchase falls well within range.

Applications are not made to Housing Australia directly. A qualifying buyer applies via one of the participating lenders, a list that includes all major banks and a range of non-bank lenders. The lender assesses eligibility using normal serviceability standards but may incorporate the Government guarantee into the LVR test. Allocation is on a first-come basis against the annual cap. No separate LMI application is required; the guarantee effectively extinguishes the obligation.

Beyond LMI: Other Considerations for First Home Buyers

Eliminating LMI does more than lower upfront cost. It preserves the borrower’s equity, improves the loan-to-value ratio for future refinancing, and may allow the borrower to direct saved funds toward stamp duty (where state concessions do not fully apply) or toward offset and redraw facilities. However, the FHBG does not remove interest rate risk or property market risk. The borrower remains exposed to rate movements and valuation fluctuations.

Potential buyers should also note that LMI-waived loans may carry a modest pricing overlay from some lenders, often as a small loading on the variable rate compared to a 20 per cent deposit loan. Borrowers should consider at least three quotes across participating lenders to confirm the net benefit of the LMI saving.

Conclusion

The First Home Guarantee will continue to operate in 2026 with expanded capacity, giving eligible first home buyers a clear path to saving $20,000–$25,000 in LMI premiums on a $700,000 property purchased with a 5 per cent deposit. The saving is structural – it is not a temporary rebate – and flows directly from the Government-backed credit enhancement.

Prospective buyers should verify their individual eligibility against the latest scheme criteria and property price caps on the Housing Australia website and, before taking any loan offer, seek a detailed comparison from a qualified mortgage broker.
