Interest Rates Are Shifting, What It Means for Your Next Purchase

The cash rate has moved more in the first half of 2026 than it did across all of 2025. If you are sizing up an investment property purchase, or considering whether an SMSF can borrow to buy one, the current environment changes several inputs worth understanding before you proceed.

Where Rates Stand Right Now

The RBA lifted the cash rate three times in 2026: 25 basis points to 3.85% in February, 25 basis points to 4.10% in March, and a further 25 basis points to 4.35% in May. The central bank then held steady at its June meeting, pausing after three consecutive hikes as it weighed slowing growth, high inflation, and the impact of oil supply disruption.

The rises were driven by CPI inflation of 4.2% in April 2026, well above the RBA's 2-3% target, partly fuelled by global energy and commodity prices. The full economic impact of the three rate rises in 2026 has not yet fully flowed through to households and businesses.

On what comes next: with rate cuts unlikely in the near future, the major banks have started to question whether we will finally see cuts in 2027, and three of the four are predicting relief by mid-year. That is not a guarantee; it is a forecast. Plan for the rate environment you are in, not the one you hope is coming.

What This Means for Standard Investment Lending

For PAYG borrowers and business owners borrowing to buy an investment property personally, the rate environment affects two things directly: your borrowing capacity (what lenders will approve) and your ongoing cash flow (what the property costs to hold each month).

For variable-rate home loan holders, the three 2026 rate rises totalling 0.75% add approximately $270 per month on a $600,000 loan with 25 years remaining. That figure scales with loan size. On a $900,000 investment loan, the same movement adds roughly $400 per month. Your actual repayments depend on the rate you are offered and your loan structure, and a licensed broker can model your specific numbers.

A few things are worth thinking through at this point in a rate cycle:

1. Serviceability buffers matter more at higher rates. Lenders assess your ability to service the loan at a buffer above the actual rate (currently at least 3% above the loan rate under APRA guidance). A higher starting rate means a higher test rate.
2. Fixed versus variable is a genuine decision. With markets divided on whether further hikes are coming, fixing part of a loan locks in certainty but removes flexibility. A licensed broker can walk through the trade-offs for your specific situation.
3. Rental income assumptions need to be realistic. Do not assume the rent will automatically cover your holding costs. Get an independent rental appraisal before you commit. Vacancy periods happen, and they hit cash flow hardest when rates are elevated.

The SMSF LRBA Picture

For SMSFs borrowing to buy property via a Limited Recourse Borrowing Arrangement (LRBA), the rate environment adds a layer on top of the structural premium that already applies.

SMSF loan rates generally sit above standard owner-occupied home loan rates because the borrowing must be structured as a limited recourse borrowing arrangement, which is more complex to assess and offered by fewer lenders. Fewer lenders write SMSF loans than standard mortgages, most major banks no longer offer them, so there is less downward pricing pressure.

For related-party LRBAs (where a member lends to their own fund), the ATO sets safe harbour rates under Practical Compliance Guideline PCG 2016/5. For the 2026-27 financial year, the ATO safe harbour rate for real property is 9.35% (up from 8.95% in 2025-26), and for listed securities it is 11.95% (up from 10.95%). These rates move with the RBA's benchmark lending indicators, so the 2026 rate cycle has pushed them up. An SMSF specialist accountant can confirm the current year's figure before any arrangement is structured.

For third-party LRBA lenders, rates sit independently of the safe harbour figures. You typically need a 30-40% deposit and a fund balance of $250,000 or more. Lenders cannot take a borrower's other super savings as security, so they require higher deposits and more stringent serviceability assessments than standard investment lending.

One structural rule that does not change with the rate environment: an SMSF can only buy property via an LRBA using a single-contract purchase, either a completed property or a land-and-build contract written as one document. A two-part off-the-plan contract (separate land contract, separate build contract) does not comply with the Superannuation Industry (Supervision) Act 1993. That is a compliance issue, not a rate issue, and it applies regardless of where the cash rate sits.

A Worked Scenario: Investment Property in Accumulation Phase

Consider a couple in their late 40s with an SMSF in accumulation phase. They are looking at a residential investment property priced at $750,000 using an LRBA. For illustration only, not a projection of actual outcomes:

• Deposit required: at a 70% LVR, roughly $225,000, plus stamp duty and setup costs. Some lenders require more.
• Rental income: taxed at 15% inside accumulation phase. If the property generates $30,000 in gross rent annually, the fund pays approximately $4,500 in income tax on that rental income, lower than most personal marginal rates.
• Holding costs: at elevated rates, a $525,000 LRBA loan is materially more expensive to service than it was two years ago. The fund needs sufficient cash flow from contributions and existing assets to cover repayments and a liquidity buffer. Lenders will stress-test this.
• Capital gains: if the property is held for more than 12 months and sold while the fund is still in accumulation phase, the effective CGT rate is 10% (a one-third discount on the 15% accumulation rate). In pension phase, up to the Transfer Balance Cap, it is 0%.

This scenario shows why the rate environment affects SMSF borrowing decisions differently than personal borrowing. The fund's tax position can partially offset higher holding costs, but only if the fund's cash flow can sustain repayments through the full rate cycle without forcing a sale.

What to Do Next

If you are seriously weighing an investment property purchase or an SMSF property in this rate environment, three concrete steps make sense before you commit:

1. Get your borrowing capacity assessed now, not at settlement. A licensed mortgage broker or SMSF-specialist lender can run current serviceability calculations based on your actual income, fund balance, and the existing rate environment. This tells you what you can borrow today, not six months ago.
2. Talk to an SMSF specialist accountant. If you are considering an LRBA, the structure, the safe harbour rate for the current year, the bare trust, and the compliance requirements all need to be in order before a contract is signed. This is not a job for a general accountant.
3. Review the property itself independently. Rental yield, vacancy rates in the area, and comparable sales are all inputs that matter more at higher holding costs. An independent rental appraisal and a buyer's agent or property professional who is not the vendor's agent are worth the cost.
