Key Takeaways
- Almost no lender counts 100% of your rent. Most assess 70% to 90%, and that spread alone moves borrowing power by tens of thousands of dollars.
- Short-stay income is where policies diverge most. Some lenders average platform statements, some shade them heavily and some substitute a hypothetical long-term rent.
- The serviceability buffer of three percentage points inflates your debts while shading trims your income, so a cash-flow-positive property can still assess as negative.
- From 1 July 2027, negative gearing on residential property is limited to new builds, with properties held at 7:30 pm on 12 May 2026 exempt.
Ask most investors how lenders treat rental income and the answer is that they take 80% of it. Close enough as an average. Some lenders assess 90% of rent, others closer to 70%, and a few treat short-stay lettings so cautiously that a strong yield barely registers.
Serviceability, not deposit, is what stops most investors from buying again. Matching an income profile to the lender whose policy reads it most favourably is the work an investment property loan broker does across the market.
Why Lenders Discount Rent Before Counting It
Shading is the lender pricing in what being a landlord actually costs.
The discount stands in for vacancy between tenancies, property management fees, maintenance, landlord insurance, council rates and strata levies where they apply. Itemising those for every application would be slow and no more accurate, so most lenders apply a flat percentage instead.
No regulator sets a fixed shading figure. The Australian Prudential Regulation Authority (APRA) states in its prudential practice guide APG 223 that prudent serviceability policies incorporate a minimum haircut of 20% on expected rental income, with larger haircuts where the risk of non-occupancy is higher. That is guidance and not a mandated number, which is why regulated lenders cluster at 80%.
Where a lender sits in that range usually reflects appetite rather than arithmetic. Lenders growing their investor book shade least, and some specialist lenders assess 90%. Conservative lenders, and any lender looking at a security type it considers volatile, shade harder. Shading is also one of the quickest levers a credit team has, so the policy may move between your first enquiry and your application.
How Each Type of Rental Income Is Assessed
The headline percentage matters less than whether the lender accepts your kind of rent at all, and acceptance turns on the tenancy behind it:
Long-Term Leases and Periodic Tenancies
A standard tenancy under a formal lease is the widest-accepted income there is. Nearly every lender takes it, shading usually sits at the friendlier end and the evidence is light. A current lease, recent managing agent statements or rent credits visible in your bank statements will typically carry it.
Short-Stay Rentals and Platform Lettings
Policies here diverge more than anywhere else. Some lenders decline short-stay income outright and instead assess a hypothetical long-term rental figure supplied by their valuer, which on a high-yield holiday property can be a fraction of what you earn. Others average one to two years of platform statements and then shade harder than they would a lease, sometimes counting around half of gross takings once cleaning, platform fees and vacancy are removed. A smaller group is more generous where you can show two years of consistent returns through a full seasonal cycle.
Granny Flats and Dual Occupancies
Rent from a second dwelling on the same title is accepted by many lenders but not all, and some cap how much of the combined rent the secondary dwelling may contribute. Council approval evidenced in the valuer’s report is commonly required, an unapproved structure usually counts for nothing, and lenders differ on whether rent counts at all where the occupant is a family member.
Holiday Lets and Serviced Apartments
Traditional holiday letting in seasonal markets meets much the same scepticism as platform income, with lenders typically wanting a longer history to smooth the peaks. Serviced apartments under a management agreement are more restricted again, with some lenders declining the security type outright, others accepting it at a materially lower maximum Loan to Value Ratio (LVR), and the return set out in the management agreement often shaded well below a standard lease.
Rooming Houses and Boarder Arrangements
Letting a property room by room can produce a higher gross return than a single tenancy and a much lower assessable figure. Many lenders will not count boarder income at all, others assess the property on a whole-of-house market rent regardless of what the rooms yield, and the ones that do accept it usually want a formal agreement per room plus a history of receipts.
Company Leases and Government Tenancies
A property leased to a company, a community housing provider or a government agency is often assessed on the lease covenant as much as the rent. The tenancy may be viewed as more secure than a private lease, which occasionally earns lighter shading, though below-market rent under a community housing agreement is assessed at the contracted figure and not at market.
SMSF Properties and Trust-Held Rentals
Rent from a property held in a self-managed super fund (SMSF) does not reach your personal serviceability. It is assessed inside the fund, on the fund’s rent and concessional contributions instead of your salary, and lenders commonly require a cash buffer to remain after settlement. The Australian Taxation Office (ATO) confirms that limited recourse borrowing arrangements entered into from 10 August 2026 may only acquire business real property, so a new residential purchase inside a fund can no longer be geared, while arrangements entered into before that date continue unaffected. Where a property sits in a discretionary trust, lenders generally look through to the distributed income and still require personal guarantees, so the debt may count against you even where the rent does not.
Acceptance, shading and evidence rules differ by lender and by property, so treat these as a general guide.
$650 a Week at 90%, 80% and 70%
A property renting at $650 per week produces $33,800 a year:
- At 90% shading, the lender counts $30,420 of annual rental income.
- At 80% shading, the lender counts $27,040.
- At 70% shading, the lender counts $23,660.
The distance between the most and least generous is $6,760 a year, around $563 a month of assessable income, from an identical property and an identical tenant. At an assessment rate near 10%, where a loan priced near 7% is tested once the buffer is added, each dollar of monthly surplus supports roughly $110 to $120 of loan, so that one difference may be worth around $65,000 of borrowing capacity on this property alone. Across three properties, the spread between the friendliest and the tightest policy can pass $150,000.
Figures here are illustrative and rounded, and the capacity effect depends on your income, your existing debts and the lender’s own calculator.
What Compounds Shading in the Same Calculation
Shading trims one side of the ledger while other rules inflate the other:
Serviceability Buffer Applied to Every Existing Debt
APRA confirmed on 28 May 2026 that the mortgage serviceability buffer remains at three percentage points. Lenders apply it to every loan you already hold, not just the one you are asking for, so an existing investment loan is modelled at a rate around 3 points above what you pay while only part of its rent counts as income. A handful of lenders assess debts held with other institutions more generously than debts held with them, which is where the compounding effect may be partly unwound.
Living Expense Benchmark Tested Against Your Household
Lenders do not simply take the household expenses you declare. They compare your figure against the Household Expenditure Measure (HEM), a benchmark built from Australian Bureau of Statistics survey data, and assess on the higher of the two, so trimming your spending in the months before an application moves the number less than investors expect. APRA’s prudential standard APS 220 requires lenders to consider a borrower’s expenses and states that benchmarks must not replace reasonable enquiries, so the declared figure still has to stand up. HEM scales with your income, household size and location, not with the number of properties you hold, so each new rental adds shaded income and a fully assessed debt while the expense floor stays where it is.
Tax Add-Back Allowed for a Geared Loss
Where a property runs at a tax loss, many lenders add part of the resulting tax benefit back to assessable income. Some add back the full effect, some only the interest component and some ignore it altogether. The ATO confirms that changes to negative gearing apply from 1 July 2027, limiting negative gearing on residential property to new builds, with properties held at 7:30 pm on 12 May 2026 exempt. Where a loss can no longer be offset against other income, the add-back that rested on it is unlikely to survive in its current form.
Debt-to-Income Ratio Measured on Gross Income
Since 1 February 2026, APRA has capped banks and other authorised deposit-taking institutions at 20% of new lending written at a debt-to-income ratio of six times or higher, measured quarterly and applied separately to owner-occupied and investment portfolios. The ratio is calculated on gross income, so shaded rent lifts the income side less than the new debt lifts the debt side. A borrower may pass serviceability comfortably and still be turned away because the lender has filled its quota for the quarter. Loans for new dwellings and construction sit outside the cap, and non-bank lenders are not subject to it.
Rental Reliance Cap Placed on Portfolio Income
Several lenders limit the share of your assessed income that may come from rent, and once you pass that line, the excess is disregarded, however well the properties perform. The cap is usually expressed as a share of your gross salary, with the allowable share rising as income rises, which is why a fourth or fifth purchase can stall at the same bank that approved the first three. Paying down debt does not move the ratio, so where reliance is the binding constraint, the answer is usually a lender that does not apply one.
Land Tax Counted as a Holding Cost
Shading covers routine holding costs, and land tax generally sits outside it as a separate commitment once your landholdings pass the state threshold. Revenue NSW sets the 2026 general threshold at $1,075,000 of combined land value, with land tax charged at $100 plus 1.6% of the excess above it. Lenders differ on whether they model it, estimate it or ignore it, so for an investor holding two or three Sydney properties it may be a four-figure annual expense that never appears in the yield calculation.
Interest-Only Term Assessed Over What Remains
An existing interest-only loan is assessed on principal and interest repayments over the term left after the interest-only period ends, not over 30 years and not at the repayment you currently make. Compressing the same balance into a shorter assessed term raises your commitments at exactly the point you are asking to borrow more, which is why your borrowing capacity may fall between one purchase and the next without your income changing.
How Proposed Rent Is Evidenced on a Purchase
Buying means there is often no rental history, so the lender assesses proposed rent, and the figure it adopts is the figure it then shades:
Existing Lease on a Tenanted Sale
Where the property sells with a tenant in place, the lease usually sets the number and most lenders take the documented rent at face value. A lease materially above market can be queried, and one expiring shortly after settlement may be assessed at the valuer’s figure instead.
Rental Appraisal From a Licensed Agent
A vacant property normally needs a written appraisal from a licensed real estate agent, often expressed as a range. Lenders generally adopt the lower end, and an appraisal from the selling agent occasionally carries less weight than one from an independent property manager.
Market Rent in the Valuer’s Report
The lender’s valuer records an opinion of market rent as part of the valuation. Where that figure and the agent’s appraisal differ, most lenders adopt the lower of the two, so an optimistic appraisal rarely improves the outcome.
Platform History for Short-Stay Income
Lenders that accept short-stay income want the earnings history from the platform itself rather than a summary, and they typically average across the full period instead of taking peak months. Gaps in the history are read as vacancy.
Yield Cap on a High-Return Property
Some lenders cap assessable rent at a maximum yield relative to the valuation, which bites on high-yield regional stock, dual occupancies and rooming arrangements. The property may return well above the cap, and the excess will not count.
Rent Estimate for an Off-the-Plan Purchase
On an unbuilt property, the valuer supplies an as-if-complete market rent, and that estimate carries the assessment through to settlement. Most lenders re-check it once the property is finished, so a fall in the local rental market between contract and completion may reduce the counted income at the point the loan is drawn. Some will not count the rent at all until a lease is signed, which matters where settlement and the first tenancy are months apart.
Borrowing Power Your Rent Can Support
Rental shading is a spread, and the lender you apply to decides where in that spread your application lands, before the interest rate enters the conversation.
That is why a decline from one bank says very little about the market. Classify your rent honestly, gather the evidence that income type requires and target the policy that suits it. The same $650 a week may support tens of thousands of dollars more borrowing at a lender whose rules were written with your kind of tenancy in mind.
The same logic applies where the deposit is coming from a property you already own, since an equity release runs through the same serviceability assessment.

Frequently Asked Questions (FAQs)
1. Does a longer lease term improve how rent is assessed?
Not usually in the shading percentage, though it can help at the margins. A lease with 12 months or more to run removes questions about whether the income continues, which matters most on property types a lender views cautiously.
2. How do lenders treat rent while a property is being renovated?
Rent that is not being received generally cannot be counted, so a property untenanted through a renovation is assessed on its expected rent after completion at most, and on nothing at all with some lenders until a tenant is in place.
Holding costs during the works still count against you, which is why a renovation period is one of the harder times to apply for new lending.
3. Will a lender count rental income paid in cash?
Only where it can be evidenced. Rent credited to a bank account, appearing on managing agent statements or supported by a formal lease is assessable. Cash without a paper trail is treated as no income at all, regardless of what the tenancy agreement says.
4. Does rental income from an overseas property count?
Some lenders accept it, usually with a further currency discount of 20% to 40% on top of the standard rental shading, and they will want tax returns or lease documents from that jurisdiction. Others exclude foreign rental income entirely while still counting the foreign debt in full.
The asymmetry catches out expatriates and recent migrants more than any other group, so the policy is worth confirming before the application.
5. What happens to the assessment if the tenant leaves before settlement?
The application is typically reassessed on the valuer’s market rent figure rather than the departed lease, which can be lower. Where the change is material, the lender may reissue the approval on different terms.
Telling your broker as soon as the tenancy ends is better than the lender discovering it at settlement.
6. Do lenders count a rental guarantee from a developer?
Most treat the period the guarantee covers with caution and assess the property on its market rent instead, on the basis that the guarantee ends and the developer may not survive it. Off-the-plan purchases carrying a rental guarantee frequently attract both a lower maximum LVR and a market-rent assessment.
