Why Property Investors Face Bigger Challenges in 2026

Securing an investment loan in Melbourne now requires more preparation than it did two years ago.

From February 2026, lenders must limit high debt-to-income loans to 20 per cent of new investor lending each quarter, meaning borrowers with total debt six times their income or more face stiffer competition for approval. Combine that with the serviceability buffer that tests every application at 3 percentage points above the loan rate, and the gap between what you can borrow for your own home versus what you can borrow for an investment property has widened.

Add in negative gearing changes that take effect from the 2027-28 income year for established properties purchased after 12 May 2026, plus the extension of the foreign buyer ban through to 30 June 2029, and the structure of investment lending has shifted noticeably. If you held contracts before mid-May or you're buying a qualifying new build, the old rules still apply. Otherwise, rental losses can only offset other residential property income, not your salary.

Debt-to-Income Limits and What They Mean for Borrowing Capacity

APRA's DTI limit applies separately to investor loans and owner-occupier loans, and each lender tracks its quarterly allocation.

Consider a buyer who earns $120,000 and already holds a $400,000 owner-occupier loan. If she applies for a $320,000 investment loan to purchase a two-bedroom unit in Coburg at the suburb's September 2026 median of $597,500, her total debt would sit at $720,000, giving a DTI of exactly six times. That application sits right at the threshold. If the lender has already allocated its 20 per cent quarterly quota to other high-DTI borrowers, the application will be declined or the loan amount reduced, even if serviceability at the buffered rate is met. Lenders do not publish their remaining quota in real time, so timing and lender selection become part of the strategy.

The practical effect is that investors with lower incomes or larger existing debts need to structure their portfolios more carefully. Paying down existing debt before applying for the next loan, or bringing in a co-borrower, are both common responses.

How the Serviceability Buffer Affects Investment Loan Amounts

Every new loan application must be assessed at a rate 3 percentage points above the actual loan product rate, a rule that has been in place since October 2021.

If a lender offers a variable rate investment loan at 6.20 per cent, your application is tested at 9.20 per cent. That buffer directly reduces the amount you can borrow. A borrower with $10,000 monthly income and $2,500 in other commitments might service a $650,000 loan at the actual rate but only $520,000 at the buffered rate. The buffer applies to both owner-occupier and investor loans, but because investment loan rates are typically 0.30 to 0.60 percentage points higher than owner-occupier rates, and because rental income is only partially recognised by most lenders, the impact on investor borrowing capacity is proportionally larger.

Where rental income is included, lenders typically apply a haircut of 20 per cent to account for vacancy, maintenance, and management costs. A property leased at $600 per week contributes $24,960 annually, but the lender will assess it at $19,968. That $5,000 difference flows directly into the serviceability calculation.

Negative Gearing Changes from the 2027-28 Income Year

Under the Treasury Laws Amendment (Tax Reform No. 1) Act 2026, losses from established residential investment properties purchased after 7:30pm AEST on 12 May 2026 can only be deducted against income from other residential properties from the 2027-28 income year onward.

Properties held at that date, including those under contract awaiting settlement, remain fully negatively geared until sold. New builds are also exempt, meaning a first-time property investor who purchases an eligible new dwelling off-the-plan in Bundoora can still offset losses against salary. A knock-down rebuild that does not increase the number of dwellings does not qualify as a new build under the exemption.

For an investor who purchases an established three-bedroom house in Preston at the September 2026 median of $1,085,000 after 12 May 2026, annual interest costs of around $65,000 at current variable rates, plus holding costs of $8,000, would create a loss of approximately $40,000 if rental income sits at $33,000 per year. Under the old rules, that loss reduced taxable income from all sources. Under the new rules, the loss can only offset gains from residential property sales or income from other rental properties. Excess losses carry forward indefinitely.

This change does not prevent investors from borrowing, but it does alter the after-tax return in the early years of ownership, particularly for negatively geared properties in higher-priced suburbs where rental yields sit below 3 per cent.

Capital Gains Tax Indexation Replacing the Discount from 1 July 2027

From 1 July 2027, the 50 per cent CGT discount for individuals on investment properties is replaced by cost base indexation using CPI and a 30 per cent minimum tax rate on real gains accruing from that date.

For properties owned before 1 July 2027 and sold after that date, the gain is split: the portion accruing before 1 July 2027 is taxed under the existing 50 per cent discount rules, and the portion accruing after that date is indexed for inflation and taxed at the higher of your marginal rate or 30 per cent. Investors can either obtain a market valuation as at 1 July 2027 or apply an ATO apportionment formula.

An investor who purchased a two-bedroom unit in Ascot Vale in June 2025 at $558,000 and sells in 2030 at $650,000 would have a nominal gain of $92,000. The portion of that gain attributable to the period before 1 July 2027 is taxed under the discount method. The portion after that date is indexed, so only the real gain above inflation is taxed, but the minimum rate of 30 per cent applies if the investor's effective rate is lower. For eligible new builds, investors can choose between the old discount and the new indexation method at the time of sale, giving flexibility depending on how inflation and property values move.

Foreign Investment Restrictions and the Extension to 30 June 2029

Foreign persons, including temporary residents, are banned from purchasing established dwellings in Australia from 1 April 2025 through to 30 June 2029, extended by over two years in the 2026-27 Budget.

Limited exceptions apply, including for properties that significantly increase housing supply, retirement villages, student accommodation, and certain Build to Rent developments. Purchases by permanent residents and New Zealand citizens remain exempt. Foreign investors can still apply for FIRB approval to purchase new dwellings or vacant land, though application fees for established dwelling exceptions were tripled from 1 April 2025.

For brokers and lenders, this ban has reduced the pool of eligible borrowers for established property investment loans, particularly in inner-city unit markets that previously attracted high levels of offshore investment. It has also increased structural demand for new builds and off-the-plan stock, where foreign investment remains permitted.

Lenders Mortgage Insurance and LVR Considerations

Lenders mortgage insurance is generally required on residential investment loans where the loan-to-valuation ratio exceeds 80 per cent.

The premium is calculated on a sliding scale based on the loan amount and LVR, and is a cost borne by the borrower. For a $480,000 loan on a $600,000 property at an 80 per cent LVR, no LMI applies. At 90 per cent LVR, the same purchase price would require a $540,000 loan and an LMI premium of approximately $15,000 to $20,000, depending on the lender and your employment profile. Some professional borrowers, including doctors and lawyers, may access LMI waivers at higher LVRs through certain lenders.

Under APRA's Prudential Standard APS 112, investment loans and interest-only loans attract higher risk weights than owner-occupied principal-and-interest loans at the same LVR, which flows through to lender pricing. Offset account balances do not reduce the loan amount for LVR purposes, so a $500,000 loan with $50,000 in offset is still treated as a $500,000 exposure when calculating capital requirements.

Rental Vacancy Rates and Serviceability in Melbourne

Melbourne's metro rental vacancy rate held at 1.3 per cent in July 2026 according to SQM Research, well below the long-term average and a signal that rental demand remains firm.

Tight vacancy conditions support rental income reliability, which in turn strengthens serviceability for investors adding to their portfolios. A buyer considering a two-bedroom unit in Footscray at the September 2026 median of $490,204 can point to the suburb's 62 per cent renter-occupancy and proximity to the CBD as evidence of sustained tenant demand. Lenders assess rental income for serviceability purposes, but most apply a 20 per cent reduction to the advertised rent to account for vacancies and costs, so a unit leased at $500 per week is assessed at $400 per week.

In suburbs with higher vacancy rates or softer rental growth, lenders may apply additional scrutiny or reduce the proportion of rental income recognised. Vacancy data at suburb level is published quarterly by SQM Research and can be used to support your application where conditions are tight.

Fixed Rate Break Costs and Refinancing Investment Loans

If you locked in a fixed rate investment loan in late 2021 or early 2022 and are now considering refinancing as rates have fallen, break costs may apply.

Break costs are calculated as the economic loss to the lender from unwinding the fixed rate hedge before maturity. If you fixed at 2.5 per cent and current wholesale rates for the remaining term sit at 4.0 per cent, the lender gains from the early exit and no break cost applies. If you fixed at 5.0 per cent and wholesale rates are now 3.5 per cent, the lender incurs a loss and charges you accordingly. The calculation is opaque and varies by lender, but break costs of $10,000 to $30,000 on a $500,000 loan are not uncommon where rate movements have been substantial.

Before refinancing a fixed rate investment loan, request a break cost estimate in writing and compare it to the interest saving over the remaining fixed period. If the saving exceeds the break cost within 12 to 18 months, refinancing is usually justified. If not, waiting until the fixed term expires is often the lower-cost option.
