Investing in property is a lending exercise as much as a property one: the right structure protects your cash flow, your tax position and your ability to buy again. This guide covers the finance fundamentals for WA investors. (General information only — TAG provides credit assistance, not tax or investment advice.)
How do investors fund a deposit without savings?
Equity. If your home has grown in value, the gap between 80% of its value and your loan balance is accessible equity:
Home worth $900,000 × 80% = $720,000 − $500,000 owing = $220,000 accessible
Released as a separate loan split, that equity becomes the deposit and costs on an investment purchase — no cash savings required. Structured properly, the investment borrowing stays cleanly separated from your home loan, which your accountant will thank you for at tax time.
What do lenders look at differently for investors?
- Rental income is discounted. Most lenders count 75–90% of expected rent toward your borrowing power, covering vacancies and costs. The percentage varies by lender — and materially changes what you can borrow.
- Rates are slightly higher. Investment loans typically price 0.2–0.6% above owner-occupied loans; interest-only adds a little more.
- Portfolio rules differ. Some lenders cap total exposure or get conservative after 2–3 properties. Serious investors sequence lenders deliberately — using the flexible ones later, when policy walls appear.
The practical upshot: the same investor can borrow $100,000+ more with one lender than another. Lender selection is the core of investment broking.
Interest-only or principal-and-interest?
Interest-only (typically up to 5 years): lower repayments, maximum cash flow, and the loan balance stays put. Many investors pair it with an offset account so spare cash reduces interest while staying accessible.
Principal-and-interest: higher repayments, but the debt shrinks and rates are lower.
The right choice depends on your strategy, other debts (paying down your home loan first is usually smarter — its interest isn't deductible) and tax position. Model both; decide with your accountant.
What should investors avoid?
- Cross-collateralisation — one loan secured by two properties. It ties your assets together, complicates selling and limits refinancing. Almost always avoidable with proper structuring.
- Maxing borrowing capacity on property #1. If the plan is a portfolio, preserve capacity for the next purchase.
- Ignoring the buffer. Lenders assess you at rate + 3% — you should too. Vacancy, repairs and rate rises all land eventually.
- Structuring for tax without advice. Negative gearing and depreciation are real, but they're your accountant's domain. We set up the lending to fit the advice, not the other way round.
The Perth picture in 2026
Perth dwelling values rose 23.9% in the year to June 2026 — the strongest of any capital — with the median around $1.05M (Cotality Home Value Index, 30 June 2026). Gross rental yields in many suburbs remain above the capital-city average and vacancy rates are near record lows.
None of that guarantees the future — but it explains why investor activity in WA is elevated, and why getting finance structured before you shop matters: pre-approved investors negotiate from strength.
