Single-parent households in Australia face a housing affordability equation that has become more unforgiving in the past 12 months. Even as the Family Home Guarantee (FHG) entered its permanent phase from 1 July 2023—with 5,000 places allocated annually—the Reserve Bank’s cash rate stood at 4.35 per cent in August 2024, pushing variable mortgage rates above 6.50 per cent p.a. for many owner-occupiers. Meanwhile, APRA’s 3.0-percentage-point serviceability buffer, unchanged since October 2021, requires lenders to assess borrowers on a rate that routinely exceeds 9 per cent. For single parents relying on a single income plus child support, that buffer can shrink borrowing capacity by 25 to 35 per cent relative to a pre-2022 rate environment. The scheme’s headline promise—a home with just a 2 per cent deposit and no lenders mortgage insurance—can therefore create a false dawn if the applicant cannot service the loan amount needed to buy in a capital city where the price cap sits at $900,000 (Sydney) or $850,000 (Melbourne). Simultaneously, the big-four banks and participating non-bank lenders overlay their own credit policies: Commonwealth Bank caps total lending at the relevant property price limit, Westpac demands a minimum of 2 per cent genuine savings proven over three months, and many institutions enforce a debt-to-income (DTI) ceiling of 6.0× or 7.0×. The result is a scheme that, while genuine in intent, requires precise alignment of income, location, property type and lender appetite. This article unpacks the Family Home Guarantee from the viewpoint of a single parent sitting down with a mortgage broker in 2024—covering eligibility, lender overlays, borrowing capacity math and the specific steps that separate a pre-approval from a decline.
How the Family Home Guarantee works
The government guarantee
The Family Home Guarantee is administered by Housing Australia (formerly NHFIC) and sits inside the broader Home Guarantee Scheme. On paper, a single parent can buy a residential property with a deposit of just 2 per cent of the purchase price. Housing Australia guarantees up to 18 per cent of the property value, which means the lender faces a maximum loss exposure equivalent to an 80 per cent LVR—well within standard balance-sheet appetite. No lenders mortgage insurance (LMI) premium is charged, a saving that can exceed $10,000 on a typical metropolitan purchase.
The guarantee covers the shortfall on a principal-and-interest home loan for an owner-occupied dwelling. It cannot be used for an investment property, a holiday home or a loan with an interest-only period. The home must be a residential property—a house, townhouse, apartment or villa, including a house-and-land package where construction is completed within 12 months—and the borrower must move in within six months of settlement or completion. The property cannot be sold while the guarantee is in place unless the guarantee is repaid or refinanced.
Who qualifies as a single parent
Eligibility expanded on 1 July 2023. Today a single parent is defined as a single natural or adoptive parent, or a single legal guardian, who has at least one dependent child. A dependent child is a child under 21 who is wholly or substantially dependent on the applicant, or a child of any age with a disability that makes them dependent. The applicant must be the sole name on the home loan and on the certificate of title. Income is tested on the individual only; the cap is $125,000 per annum for the 2023–24 tax year and will be indexed for 2024–25. The applicant must be an Australian citizen or permanent resident at the time of application and be at least 18 years old. Crucially, a single parent who has previously owned property—even if they sold it years earlier—can still apply provided they do not currently own any residential property and did not own property when they applied.
Maximum purchase prices for 2024–25
Housing Australia publishes property price caps each financial year. The caps are set by postcode and region, not by proximity to a CBD. As of 1 July 2024, the following caps apply for FHG-eligible purchases:
- New South Wales – capital city and regional centres (postcodes designated Sydney, Newcastle, Wollongong): $900,000; rest of state: $750,000
- Victoria – capital city and regional centres (postcodes designated Melbourne, Geelong): $850,000; rest of state: $650,000
- Queensland – capital city and regional centres (postcodes designated Brisbane, Gold Coast, Sunshine Coast): $800,000; rest of state: $650,000
- South Australia – capital city (Adelaide): $700,000; rest of state: $550,000
- Western Australia – capital city (Perth): $650,000; rest of state: $500,000
- Tasmania – capital city (Hobart): $600,000; rest of state: $450,000
- Australian Capital Territory: $650,000
- Northern Territory: $550,000
These caps are firm; a purchase price one dollar above the cap will trigger an automatic decline at the scheme-approval stage, regardless of the lender’s own appetite. The property can be an established dwelling or a house-and-land package, but the combined land and construction cost must not exceed the cap.
Lender policies: what the banks add
Big-four conditions
Every participating lender must accept the 18 per cent government guarantee, but each sets its own credit overlay. Commonwealth Bank’s Home Guarantee Scheme Fact Sheet, updated in June 2024, confirms that eligible single parents can borrow up to 98 per cent LVR with no LMI, subject to the scheme price cap, and that the loan must be principal and interest. CBA does not mandate a minimum genuine savings history; it will accept a gift from a family member or a lump sum from a tax refund provided the source can be documented.
Westpac’s Family Home Guarantee page, last updated 4 May 2024, requires a minimum deposit of 2 per cent from genuine savings. The bank defines genuine savings as funds held in the applicant’s name for at least three months. A gift that has been sitting in the account for a full three-month statement cycle can qualify; a fresh transfer on the day of application will not.
NAB applies a similar genuine savings expectation but is prepared to waive the requirement for an applicant who can demonstrate a strong rental ledger for 12 months without a single missed payment. NAB’s broker-originated loan guidelines, dated March 2024, also cap the maximum DTI for FHG applications at 7.0×.
ANZ accepts the guarantee but does not offer it for construction loans or for properties that require more than minor cosmetic renovation. ANZ also excludes properties in certain postcodes it deems high-risk, which can complicate a purchase in a regional town that falls within a scheme cap but outside the bank’s internal geographic appetite.
Non-bank alternatives
Bendigo Bank, Adelaide Bank and Homestar Finance all participated in the 2023–24 allocation and intend to remain in the scheme for 2024–25. Homestar’s policy guide, refreshed in February 2024, accepts a statutory declaration in place of genuine savings if the deposit is sourced from an immediate family member and the family member provides a signed gift letter. Homestar’s DTI ceiling sits at 6.0× for LVRs above 95 per cent, which is tighter than NAB and CBA but still workable for many single-parent incomes. Bendigo Bank will also consider child support income at 100 per cent of the amount stated in a formal Family Court order or a Child Support Agency assessment, provided there are at least six months of consistent bank statement evidence.
Genuine savings hurdles
The scheme itself does not require a history of regular saving. However, five of the 33 participating lenders (as at January 2024) impose a genuine savings requirement of between 2 and 5 per cent. This creates a barrier for single parents who have scrambled together a deposit shortly before applying—perhaps from a one-off bonus, the sale of a car or a government payment. A parent holding the full 2 per cent in a transactional account for less than three months will be outside the policy of Westpac, Bankwest and St.George, but inside the policy of CBA and Homestar. A broker who understands these nuances can save a client from a hard credit enquiry that ends in a decline.
Borrowing capacity reality check
APRA’s 3.0% serviceability buffer
APRA’s letter to lenders on 6 October 2021 reaffirmed the 3.0-percentage-point serviceability buffer on top of the loan product rate. As of August 2024, a typical major-bank owner-occupier variable rate for an LVR above 95 per cent sits at 6.49 per cent p.a. (comparison rate 6.73 per cent p.a.). Adding the buffer gives an assessment rate of 9.49 per cent. A loan of $450,000 over 30 years at 9.49 per cent generates a monthly repayment of approximately $3,773. A single parent earning $95,000 p.a. plus $12,000 in child support (declared and consistent) has a gross monthly income of roughly $8,917. After tax and Medicare levy, net monthly income is close to $6,800. Living expenses for a household of two, assessed using the Household Expenditure Measure (HEM) table, typically sit at $2,100 to $2,400 for a single adult with one dependent child. Lenders also allocate 3 per cent of credit-card limits as a monthly commitment. The residual surplus is around $600 to $700, which is sufficient for some lenders but insufficient for others that demand a net surplus of $800 or more after the assessed repayment. At a DTI ceiling of 6.0×, the maximum loan would be $642,000 ($107,000 × 6), but the serviceability test—not the DTI cap—becomes the binding constraint here.
Single-parent income treatment
Lenders assess child support, family tax benefit Part A and Part B, parenting payment and rental assistance if they are regular and documented. Child support received from an ex-partner must usually be proven through a Child Support Agency assessment or a binding child support agreement lodged with the court. Bank statement evidence of receipt over at least three months is the minimum. Some lenders will then include 80 per cent of the amount in the servicing calculation; others, such as Bendigo Bank, go to 100 per cent if the assessment is less than 12 months old. Family tax benefit is taken at 100 per cent if the child is under 13, because it is means-tested and tends to reduce as income rises.
Living expenses and dependants
A single parent with one dependent child triggers a higher HEM benchmark than a single applicant without children. The difference is about $300 to $400 per month. Declared ongoing childcare, private school fees or after-school care are added as a fixed monthly commitment and can reduce borrowing capacity by $50,000 to $80,000 at a 9.49 per cent assessment rate. Lenders will also scrutinise credit-card limits, afterpay accounts and any existing personal loan, because the total unsecured credit exposure feeds directly into the HEM-based net cash flow calculation.
Maximising your chances as a single parent
Steps before you apply
Get an accurate borrowing capacity estimate from a broker who runs the numbers at the full buffer rate, not the advertised rate. Check the Housing Australia price cap for the postcode you are targeting—caps can change each financial year. Obtain a Child Support Agency assessment or a court order if you intend to use child support as servicing income; back it up with at least three months of bank statements showing the deposits. Reduce credit card limits to a level you genuinely need; cancelling an unused $10,000 card can add $27,000 to your borrowing power under some lender calculators. If you are planning to use a family gift, park it in a dedicated savings account three months before application, particularly if you may apply through Westpac or Bankwest.
Common rejection points
Broker feedback from FY2024 flags the following as the most frequent causes of decline: property price above the scheme cap for that postcode (common where a buyer selects a home within a few thousand dollars of the cap and a valuation comes back slightly higher); DTI exceeding the lender’s internal ceiling, often triggered by an existing car loan or HECS-HELP debt that gets grossed up; child support income rejected because the payer has an inconsistent payment history or is self-employed; and credit file impairment—even a small default under $500 can lead to automatic decline at a major bank, though some non-banks may accept a paid default that is older than 12 months.
Alternatives if the Family Home Guarantee isn’t right
Single parents who exceed the income cap or the property price cap can look at the First Home Guarantee (FHBG), which requires a 5 per cent deposit but has a higher property price cap in many regions—$900,000 in Sydney, $800,000 in Melbourne—and allows joint applications if a partner is included. The Regional First Home Buyer Guarantee (RFHBG) is another option for those buying outside a capital city, with 10,000 places in 2024–25. State-based shared-equity programs, such as the Victorian Homebuyer Fund or WA Keystart, can reduce the required loan amount further. The Commonwealth Help to Buy shared equity scheme, scheduled to commence later in 2024, will allow eligible low- and middle-income buyers—including single parents—to purchase with a 2 per cent deposit and a government equity stake of up to 30 per cent for existing homes, which could ease serviceability pressure substantially, although it will operate through a limited panel of lenders.
What a single parent should do now
A single parent sitting down with a broker in the second half of 2024 needs to run precise numbers, not rely on the scheme’s 2 per cent deposit tagline. First, calculate borrowing capacity using the APRA buffer rate—typically 9.5 per cent—and test it against the property price cap for the intended postcode; if the gap is too wide, redirect the search to a cheaper region or a different scheme. Second, establish the 2 per cent deposit in a form the chosen lender will accept: a seasoned savings balance, a gift letter plus a three-month statement, or a documented lump sum that CBA will take without seasoning. Third, formalise any child support income with a Child Support Agency assessment or a binding written agreement, because almost no lender will use undocumented family payments in the servicing calculator. Fourth, obtain a copy of the most recent Housing Australia price cap table (the 2024–25 caps published on 1 July 2024) and cross-check the exact postcode—an agent’s sales board may list a suburb within a high‑cap postcode, but a few kilometres can move the property into a lower‑cap area. Fifth, engage a broker who is accredited with at least five participating lenders; a direct walk‑in to a single bank branch risks missing a non‑bank that will take child support at 100 per cent or accept a rental ledger in place of genuine savings. The Family Home Guarantee remains one of the most powerful tools for a single parent trying to break into the Australian housing market, but its value is fully realised only when the numbers are run against real credit policies, not headline promises.
