TL;DR
- Twenty per cent remains the cleanest deposit benchmark for a second home, avoiding LMI and opening the widest lender choice, with 5% to 6% in buying costs on top.
- First-home supports like the 5% Deposit Scheme and state grants are tied to first-home buyer status and generally do not carry across to a second purchase.
- A deposit can combine cash savings, usable equity at 80% LVR minus the existing loan, gifted funds, or guarantor support — the mix matters more than the total.
- Serviceability compresses sharply on a second purchase because APRA’s 3 percentage point buffer applies to both loans, often halving the borrowing capacity a teacher had as a first-home buyer.
For Australian teachers thinking about buying a second property in 2026, the deposit conversation has become more complex than it used to be. Interest rates are still elevated compared to the lows of the early 2020s, serviceability buffers remain tight, and the first-home schemes that have expanded in recent years do not automatically carry across to buyers who already own property. At the same time, many teachers who bought a few years ago are now sitting on meaningful equity, which changes what “deposit” actually means in practice.
The question most teachers ask — “how much deposit do I need for a second home?” — does not have a single answer. It depends on whether the property will be your next owner-occupied home or an investment, whether you are keeping the first property or selling it, whether you have equity to draw on, and how lender policy treats your income profile. This article walks through what genuinely counts as a deposit for a second home in 2026, how lenders approach these applications, where teacher-specific considerations help or hurt, and how to decide whether your current position is strong enough to proceed.
The Honest Answer on Deposit Size
Twenty per cent of the purchase price remains the cleanest benchmark for a second home. At that level, you avoid Lenders Mortgage Insurance (LMI), access the widest pool of lenders, and typically secure sharper interest rates. For a 700,000 property, that translates to 140,000 for the deposit plus another 35,000 to 45,000 for buying costs, giving a total of roughly 175,000 to 185,000.
Below 20%, the numbers still work but the picture changes. Deposits between 10% and 20% usually trigger LMI, which is capitalised into the loan and paid over the life of the mortgage. For second-home buyers, LMI tends to be more expensive than it would be on a first-home purchase at the same Loan to Value Ratio (LVR), partly because the premium structure reflects the borrower’s overall risk profile including the existing mortgage.
Deposits of 5% are theoretically possible for some buyers, but the low-deposit pathways that exist in 2026 are predominantly tied to first-home buyer eligibility. The Australian Government 5% Deposit Scheme administered through Housing Australia has expanded from October 2025 with unlimited places and revised property price caps, but it is structured for first-home buyers purchasing a property they will live in. A teacher who already owns a home will generally not qualify, regardless of how favourable the terms look on paper.
What Actually Counts as a Deposit in 2026
The word “deposit” covers more than just the cash sitting in your savings account. Lenders accept several sources, and for second-home buyers, the mix often matters more than the total.
Cash savings
Genuine savings — funds you have accumulated over time and can demonstrate through at least three to six months of account statements — remain the gold standard. Lenders view savings history as evidence of financial discipline, not just capacity. For teachers applying with less than 20% deposit, most lenders want to see at least 5% of the purchase price as genuine savings, with the rest coming from other sources.
Equity in your existing home
For teachers who already own property, equity is often the most efficient deposit source. Usable equity is typically calculated as 80% of your current home’s value minus the existing loan balance. This equity can be released through a separate loan split against your current property and used to cover both the deposit and buying costs on the new purchase. We will cover the mechanics in more detail shortly.
Gifted funds
Most lenders accept non-repayable gifts from immediate family, usually supported by a signed statutory declaration confirming the funds are not a loan. Gifted funds count towards your deposit but are not always treated as genuine savings, so a borrower relying entirely on a gift may still need some savings history to satisfy the lender’s criteria.
Guarantor support
A family member — typically a parent — can offer their property as additional security to support your borrowing. This is more common for first-home buyers but can occasionally work for second-home purchases, particularly where the teacher has built equity in their existing home but not enough to cover the full deposit gap. Lenders generally limit the guarantor’s exposure to a defined portion of their property’s value.
Second Home vs First Home: Why the Rules Change in 2026
Many teachers approach a second purchase assuming the same supports they used the first time around will still be available. In most cases, they will not. Understanding which doors close when you buy your second property is essential to realistic deposit planning.
The 5% Deposit Scheme and other Home Guarantee Scheme products administered through Housing Australia are tied to first-home buyer status. Once you have owned property, eligibility generally ends. There are narrow exceptions — for example, under the Family Home Guarantee for eligible single parents and legal guardians, which permits a 2% minimum deposit and does not require first-home buyer status — but these are specific and capped.
State-based First Home Owner Grants and stamp duty concessions are similarly tied to first-home status and owner-occupier use. Help to Buy, the separate shared equity scheme, has its own eligibility rules that typically exclude existing homeowners.
The practical implication is simple: for most second-home purchases in 2026, you are in the standard lending market, without the deposit shortcuts available to first-home buyers. This is not a barrier — most second-home buyers proceed on the standard 10% to 20% deposit path — but it means the deposit planning has to be grounded in normal lending rules, not scheme-based shortcuts.
How Lenders Assess Second-Home Borrowers
The deposit is only half the conversation. Lenders also assess whether you can service the new loan on top of your existing commitments, and their approach to second-home applications is different to a first purchase in several important ways.
Under Australian Prudential Regulation Authority (APRA) guidance, lenders apply a serviceability buffer of at least 3 percentage points above the actual interest rate when assessing your ability to repay. If the combined rate is 6.5%, the lender is testing whether you can service both loans at 9.5% or higher. For second-home buyers, this buffer applies to both the existing loan and the new one, which compresses borrowing capacity meaningfully.
Lenders also consider:
- your existing home loan repayments, assessed at buffered rates rather than your actual repayment
- any projected rental income if the first property is being rented out, typically shaded to 75% to 80% to account for vacancy and costs
- all other debts including credit card limits (not balances), personal loans, car loans, and Higher Education Loan Program (HELP) balances
- your assessed living expenses, benchmarked against the Household Expenditure Measure or your declared expenses, whichever is higher
- the new property’s classification as owner-occupied, second home, or investment, which affects interest rate and policy
A teacher who could comfortably borrow 650,000 as a first-home buyer may find their capacity for a second purchase is 400,000 to 500,000 once the existing mortgage and buffers are factored in. This is normal, but it frequently surprises borrowers who were expecting similar numbers to their first application.
How Teacher Income Affects the Deposit Strategy
Teachers are generally treated as stable borrowers, but lender policy on teaching income has more variation than most applicants realise. The way your income is assessed directly affects how much you can borrow, which in turn affects how large a deposit you will need to make the purchase work.
Permanent teachers
Permanent base salary is used at 100% by nearly all lenders. Permanent teachers with two or more years of consistent employment often qualify for profession-based concessions at some lenders, including LMI waivers at 85% or 90% LVR. For a second-home purchase, a teacher eligible for an LMI waiver can effectively reduce the deposit required to 10% or 15% of the purchase price without paying the full LMI cost that would normally apply — which is one of the more meaningful profession-based benefits still available to second-home buyers.
Contract and fixed-term teachers
Contract teachers can still qualify, but the assessment is tighter. Lenders typically want at least twelve months in the current role, a pattern of renewal, or a contract extending well beyond the expected settlement date. Contract teachers also need to allow extra time for pre-approval and often face slightly more conservative income treatment, which can push the deposit requirement higher in practice if borrowing capacity is the constraint.
Casual and relief teachers
Casual and relief teaching income is generally shaded by 20% or more, and some lenders will not count it at all without a two-year history. For a second-home purchase, where borrowing capacity is already compressed by the existing mortgage, this shading can make the difference between approval and decline. Teachers relying heavily on casual work often benefit from working with a broker to identify lenders with more favourable casual income policies.
Allowances and additional pay
Leadership responsibility allowances, rural and remote loadings, co-curricular payments, and special duties pay are treated inconsistently across lenders — some include them at 100%, others at 80%, and a few exclude them entirely. For a teacher whose base salary is tight on serviceability, correctly including allowances can unlock meaningful additional borrowing capacity, which in turn reduces pressure on the deposit.
The Four Common Deposit Pathways for Second-Home Buyers
Most teachers buying a second property in 2026 fall into one of four deposit structures. Knowing which one fits your situation makes the planning considerably easier.
Full cash deposit
Saving a 20% cash deposit on a second property is the cleanest approach but rarely the fastest. For a 600,000 property, that means 120,000 plus around 35,000 in buying costs — a substantial sum to accumulate while also servicing an existing mortgage. This pathway suits teachers with strong savings capacity and no particular time pressure, or those who prefer to keep their first property’s equity untouched.
Cash plus equity
This is the most common pathway for teachers who already own. A portion of the deposit comes from accumulated cash savings, and the balance is drawn from equity in the first property through a separate loan split. For example, a teacher with 40,000 in savings and 100,000 in usable equity can comfortably fund a 20% deposit and buying costs on a 500,000 property, often without any cash top-up required at settlement. The interest on the equity release is deductible if the funds are used for investment purposes and structured correctly.
Guarantor-backed structure
Less common for second-home purchases, but still possible where a parent or close family member offers their property as additional security. This typically suits younger teachers whose first home has not yet built enough equity and who have strong income but limited cash. The guarantor arrangement is usually released once the combined LVR falls below 80% through repayments and capital growth.
Low-deposit with LMI
If you are working out how to fund another property while keeping your current home, it may help to look at second home loans for teachers. This can be especially relevant when you are buying a property for your own future use rather than as a standard investment, because lenders may treat the application differently depending on whether the home will be lived in, held as a second residence, or supported partly by equity from your existing property.
Going in at 10% or 15% deposit with LMI is a legitimate pathway for teachers who want to move quickly and have strong serviceability. Profession-based LMI waivers at some lenders can meaningfully soften this cost. The trade-off is a larger loan, capitalised LMI paid over the life of the mortgage, and tighter cash flow from day one. For some teachers, this is the right choice; for others, waiting twelve months to reach 20% produces a materially better long-term position.
Upfront Costs Beyond the Deposit
Deposit planning that stops at the deposit itself leads to nasty surprises at settlement. For a second-home purchase, the additional costs typically add 5% to 6% on top of the purchase price.
Stamp duty is the largest single cost on most purchases. Second-home buyers do not access first-home stamp duty concessions, which can mean a difference of 15,000 to 25,000 or more on a standard metro property compared to what a first-home buyer would pay. Conveyancing and legal fees, usually 1,500 to 3,000 depending on complexity, cover the legal work through to settlement.
Building and pest inspection reports run 500 to 800 combined and are well worth the cost. Loan application and valuation fees vary by lender but typically total 500 to 1,000. If LMI applies, the premium sits on top of all of this — for a 90% LVR loan on a 600,000 property, LMI can easily be 15,000 to 20,000. Home and contents insurance is usually required to be active from settlement day, adding another 1,500 to 2,500 in the first year.
A realistic cost budget for a 600,000 second-home purchase at 80% LVR would look roughly like this: 120,000 deposit, 25,000 to 30,000 stamp duty depending on state, 2,500 conveyancing and legal, 700 inspections, 800 loan and valuation fees, and 2,000 initial insurance. That is around 151,000 to 156,000 in total — a very different number to the headline “20% deposit.”
Step-by-Step Preparation for 2026
Moving from planning to settlement on a second-home purchase follows a predictable sequence. Understanding it upfront helps you time the deposit build, pre-approval, and property search without unnecessary friction.
Start by establishing a realistic budget. This means modelling both the deposit and the total buying costs, plus a cash buffer for the first six to twelve months of the new property’s holding costs. From there, confirm your deposit structure — cash only, cash plus equity, guarantor, or low-deposit with LMI — and gather the supporting documentation the lender will want to see.
For teachers, this documentation typically includes at least three months of recent payslips, employment verification letters (particularly if on contract), bank statements covering three to six months of savings history, evidence of any allowances claimed, details of existing debts including credit card limits, and recent statements for your current home loan. Contract and casual teachers should plan for additional evidence such as contract renewal letters, school letters confirming ongoing engagement, or twelve to twenty-four months of consistent casual income history.
From there, seek pre-approval before serious property hunting. Most lenders issue pre-approval within seven to ten business days for straightforward applications, valid for around ninety days. With pre-approval in hand, conduct the property search within a clear budget, order inspections once a property is identified, and progress through formal approval to settlement over a further thirty to sixty days.
Real Teacher Scenarios
These examples illustrate how the deposit conversation plays out in practice. Figures are indicative and vary with individual circumstances.
Scenario one: The permanent teacher upgrading her family home
A permanent secondary teacher in Brisbane owns a home worth 780,000 with a loan balance of 380,000. She wants to buy a 950,000 family home and sell the first property to release full equity. Her usable equity at 80% LVR is 244,000, which combined with the net proceeds from selling the first property gives her more than enough for a 20% deposit and costs on the new purchase. Because the sale and purchase timing needs to align, her broker structures bridging finance to carry her through the transition. No LMI applies, and she uses an offset account against the new loan to manage cash flow.
Scenario two: The contract teacher buying an investment unit
A contract teacher in Melbourne on her fourth annual renewal owns a home worth 620,000 with a loan balance of 290,000. She wants to buy a 480,000 investment unit. Usable equity at 80% LVR is 206,000, more than enough to cover the 96,000 deposit and 28,000 in buying costs on the investment. Her contract income is accepted because of her renewal history, and the rental appraisal of 430 per week is shaded at 75%. The broker structures the equity release as an investment-purpose split, keeping the interest deductible and the two loans cleanly separated. No LMI applies because both properties remain under 80% LVR.
Scenario three: The teacher who needs to wait
A permanent primary teacher in regional New South Wales owns a home worth 450,000 with a loan balance of 310,000. He has a HELP debt of 30,000, a small car loan, and 8,000 in savings. He wants to buy a 420,000 second property for his parents to live in. Usable equity is 50,000, which would cover part of the deposit but not the full buying costs, and his serviceability is tight. The broker’s advice is straightforward: use the next twelve to eighteen months to pay down the car loan, build savings to around 25,000, and let ongoing repayments and any capital growth strengthen the equity position. From there, the strategy becomes workable without stretching the household’s cash flow.
Mistakes to Avoid in 2026
Deposit strategies for second-home purchases tend to fail in predictable ways. Being aware of the common mistakes is the best protection against making them.
The first is assuming first-home schemes still apply. The 5% Deposit Scheme, First Home Owner Grants, and stamp duty concessions are almost always tied to first-home buyer status. Planning a purchase around schemes you no longer qualify for is the quickest way to discover a funding gap at formal approval.
The second is under-budgeting for costs. The difference between a 20% deposit and 20% plus full buying costs is often 30,000 to 40,000 on a typical purchase. Teachers who save exactly the deposit amount frequently find themselves scrambling for stamp duty or LMI at settlement.
The third is treating equity as free money. Equity is additional debt secured against your existing home. Using it increases total borrowings and exposes your first property to the combined risk, which matters more during periods of higher rates or tighter cash flow.
The fourth is making major financial changes before settlement. Changing jobs, opening new credit cards, or taking on new debt between pre-approval and settlement can trigger lender reassessment. Teachers on contract should be particularly careful not to let a contract renewal lapse during this window.
The fifth is over-relying on rental projections to justify the purchase. Lenders shade rental income for a reason, and real-world vacancy and management costs can absorb margins that looked comfortable on a spreadsheet.
The Bottom Line
The deposit required for a second home in 2026 is not a single number — it is a planning exercise that depends on your current equity, income profile, existing debt, and the purpose of the new property. For most teachers, 20% of the purchase price plus 5% to 6% in buying costs remains the cleanest target because it avoids Lenders Mortgage Insurance and opens the widest range of lenders. Lower deposits are workable but carry additional cost and tighter serviceability, and the first-home schemes that help many buyers into the market do not generally carry across to a second purchase.
The strongest positions come from teachers who model the full cost, not just the deposit; use equity deliberately and structure it as a separate split rather than blending it into an existing loan; understand how their specific income profile will be assessed; and commit to a clear purpose for the new property before applying. When the numbers do not yet support the purchase, delaying twelve to eighteen months to strengthen savings, reduce other debts, or build more equity almost always produces a better outcome than stretching into a borderline approval. The teachers who treat the second-home deposit as a structured plan rather than a hurdle tend to find that by the time they are ready to buy, the rest of the process runs far more smoothly.
Frequently Asked Questions (FAQs)
1. How much deposit does a teacher need for a second home in 2026?
Twenty per cent of the purchase price remains the clean benchmark because it avoids Lenders Mortgage Insurance and gives the widest lender choice. Lower deposits are possible — typically 10% to 15% with LMI applying — and some permanent teachers may qualify for profession-based LMI waivers at higher LVRs. On top of the deposit, budget for 5% to 6% in buying costs including stamp duty, legal fees, inspections, and valuation fees.
2. Can I still use the 5% Deposit Scheme for a second home?
Generally no. The Australian Government 5% Deposit Scheme administered through Housing Australia is designed for first-home buyers and requires the purchase to be the buyer’s principal place of residence. Teachers who already own property will not normally qualify, regardless of the scheme’s expanded places and property caps from October 2025. Narrow exceptions exist, such as the Family Home Guarantee for eligible single parents and guardians, but these have their own specific eligibility rules.
3. Will I have to pay Lenders Mortgage Insurance if my deposit is under 20%?
In most cases yes, unless you qualify for a profession-based LMI waiver at your chosen lender. LMI is capitalised into the loan and paid over its life, and the cost rises steeply as LVR increases above 80%. Some permanent teachers with strong income profiles qualify for LMI waivers at 85% or 90% LVR, but these depend on the specific lender’s policy and your eligibility. Confirming LMI cost upfront prevents surprises at formal approval.
4. Can I use equity in my first home instead of cash savings?
Yes, and for many teachers this is the most efficient pathway. Usable equity is generally calculated as 80% of your current home’s value minus the existing loan balance. This can be released through a separate loan split and used to cover the deposit and buying costs on the new purchase. Most lenders still want to see some genuine savings history alongside equity, and structuring the release as a separate split rather than redrawing into a mixed account preserves future flexibility.
5. Do contract or casual teachers need a bigger deposit?
Not always, but the assessment is tighter and can effectively require a larger deposit if borrowing capacity is constrained. Contract teachers typically need at least twelve months in the current role and evidence of renewal. Casual income is usually shaded by 20% or more and may require a two-year history. Where serviceability is the limiting factor, a larger deposit can sometimes bridge the gap, and working with a broker who knows which lenders treat contract and casual income favourably makes a material difference.
6. What happens if the property valuation comes in low?
If the lender’s valuation is below the purchase price, your effective LVR rises and you may need to contribute additional funds to maintain the same deposit percentage. For example, if you agreed to pay 600,000 but the valuation comes in at 570,000, the lender’s 80% LVR calculation is based on 570,000, not 600,000 — reducing their willingness to lend by 24,000. This can be managed through additional deposit, renegotiating the purchase price, or accepting a higher LVR with LMI, but it is worth budgeting a valuation buffer as part of your deposit plan.
7. Is it better to save a larger deposit or buy sooner with LMI?
It depends on your circumstances, the property market, and your borrowing position. Saving to 20% avoids LMI and widens lender choice, but waiting twelve to eighteen months in a rising market can cost more than the LMI you would have paid. Buying sooner with LMI locks in the purchase price and starts building equity earlier, but adds cost to the loan and tightens cash flow. For second-home buyers, the calculation often favours waiting to 20% if the market is stable, and buying sooner if the market is moving and serviceability is strong.
