Where to check the official rules and rates

The Reserve Bank of Australia kept the cash rate target at 4.35% at its 11 August 2026 meeting; this article suggests recording 2 items to confirm, such as the rate type and any fixed period, before comparing brokers. RBA also publishes F-series statistics tables each month with housing loan weighted average rates by owner-occupier and investor, variable and fixed, plus bank funding costs. APRA supervises deposit-taking institutions and publishes home loan prudential standards including a serviceability buffer for 2026; this article suggests you check 3 written items in any loan offer, such as the rate, fees and repayment frequency. ASIC regulates credit licensing, and its MoneySmart site gives home loan fee guidance for 2026; this article suggests keeping 2 records of each broker's disclosures. FIRB explains that foreign persons and temporary residents usually need foreign investment approval to buy residential property, with fees tiered by property value on its site, and the four major banks publish home loan products and rates on their own pages. Start every comparison from the official data, because the published rate environment is the baseline each offer should be measured against.

How to compare mortgage brokers for refinancing

Confirm the broker holds a credit licence you can verify on ASIC's public register, and remember that industry-body membership is not an ASIC credit licence. Ask each broker to show offers from several lenders, then place the written quotes side by side. Compare the disclosure on rate type, fixed period, fees, break costs and offset account. A broker is worth shortlisting when you can see the licence, the lender range and the written offer in plain form.

How to archive your materials and evidence

Save the loan contract and disclosure documents as PDF files you control, rather than the copies the broker holds. Record the rate, whether fixed or variable, its validity, repayment frequency, fees including early repayment penalties, and offset terms. Keep your own file separate from the broker's, and label each document with its issue date and source. Good records turn a verbal promise into something you can check against the signed contract.

What to verify before you act

Verify that each rate, fee and offer carries a date and a source you can trace, and check the loan-to-value ratio and whether lenders mortgage insurance applies, since the threshold differs by lender. If you are a foreign person or temporary resident, check the FIRB approval rules for residential property before treating any plan as settled, and confirm how the bank assesses income, visa status, deposit and repayment capacity, because overseas income needs verifiable proof and standards vary. Act after the written contract matches the quote, with no missing fee or condition.

How to do a final check

Re-read the signed contract for amount, rate type, validity, repayment frequency, fees and offset terms, and confirm the broker's credit licence on the ASIC public register. Make sure the RBA cash rate context is clear before you commit. The final check is your last chance to catch a mismatch between the quote and the contract.
