Building a Property Portfolio

Usually through equity rather than fresh savings. As the first property grows in value and the loan is paid down, usable equity builds up — broadly the difference between roughly 80 per cent of the property value and the loan balance, before lenders mortgage insurance considerations. That equity can be released through a separate loan split and used as the deposit and costs on the next purchase. The mechanics matter: the released funds must be kept as their own split with a clear investment purpose so the deductibility character of the borrowing is supported, rather than being mixed with private spending. Whether any release is possible depends on the lender assessment, the valuation and your serviceability at the time.

Serviceability is a lender measure of whether your income covers your commitments at an assessment rate that includes a buffer above the actual rate. Each new loan adds to the commitments side, and existing investment loans are often loaded at their assessed repayment even where you pay interest-only. Rental income is generally shaded — only a portion is counted. The combined effect is that borrowing capacity does not grow in a straight line; investors commonly reach a point where the next purchase simply will not pass any lender on current income. Reaching that ceiling is not failure — it is a signal to pause, consolidate, lift income or rental returns, or wait for values and balances to move. Approval always depends on the lender assessment, lending criteria and your circumstances.

Cross-collateralisation is where one property is used as security for the loan on another, so the lender holds a web of properties against a web of loans. It can feel convenient early on, but it tends to create problems as the portfolio grows: selling one property can trigger a full revaluation and reshuffle of the others, releasing equity becomes harder, and you can become locked into one lender who controls the whole structure. A standalone security structure — each property securing only its own loan, with equity released as separate splits — keeps the portfolio flexible. Untangling cross-collateralised loans later is possible but can involve revaluations, refinancing and cost, so it is better considered before the structure sets.

Land tax in NSW is assessed annually on the total unimproved land value you hold above the tax-free threshold, and the holdings of a single owner are aggregated together. That aggregation means each additional property can push more of your land value into higher land tax, and the marginal cost of the next property is not just its own land tax but the effect on the whole holding. Different ownership structures — individuals, joint owners, companies and trusts — are assessed under different rules and thresholds, and some structures do not receive the tax-free threshold at all. Land tax is one of several factors in the ownership decision, and the right answer depends on your overall position and the law for the relevant year.

It can. The first property is often bought in personal names without much thought, but by the third or fourth the cumulative effect of those early decisions becomes visible — in land tax aggregation, in CGT treatment on eventual sale, in asset protection, and in which lenders will fund the structure. Under the rules for the current income year, individual ownership generally retains access to the 50 per cent CGT discount on eligible personal capital gains, a company generally cannot access that discount, and trusts can often stream income and capital gains but carry their own complexity and lender constraints. That comparison shifts under enacted law: for CGT events happening on or after 1 July 2027 the discount percentage is 0 per cent for resident individuals and for trusts that are not complying superannuation entities on ordinary assets, with cost-base indexation running only from 1 July 2027 applying instead, while complying superannuation entities keep the 33⅓ per cent discount. Separately, from the 2027–28 income year excess residential-property deductions are quarantined and carried forward; ordinary discretionary and unit trusts are not carved out of that rule, and residential rental income distributed through a trust keeps its character in a beneficiary’s own calculation. Changing structure later can itself be a CGT and stamp duty event. There is no single best structure — the comparison depends on your goals, and we model it in writing for your specific portfolio.

Each property is its own CGT asset, and gains or losses are generally crystallised on disposal rather than across the portfolio as a whole. Under the rules for the current income year, holding for more than 12 months may allow the CGT discount for eligible individuals and trusts; timing a sale across financial years, or against a year with lower other income, can change the outcome, and capital losses on one property can generally offset capital gains on another in the same or later years. The discount is changing under enacted law: for CGT events happening on or after 1 July 2027 the discount percentage becomes 0 per cent for resident individuals and for trusts that are not complying superannuation entities on ordinary assets, with cost-base indexation running only from 1 July 2027 applying instead, while CGT events before 1 July 2027 keep the existing 50 per cent discount where the conditions are met. For the complete timeline, transitional rules and who keeps a discount, see our dedicated resource on the CGT discount changes from 1 July 2027, linked below. These are general points only, current as at 13 July 2026, and depend on your circumstances.

They change where a net rental loss can go, and they look at the portfolio as a whole. Schedule 2 of the Treasury Laws Amendment (Tax Reform No. 1) Act 2026 (No. 49 of 2026) is enacted law and applies in relation to the 2027–28 income year and later years. Negative gearing is not abolished. From 2027–28, if the amounts you could otherwise deduct for using or holding residential dwellings as residential accommodation exceed your assessable income from doing so, the excess is not deductible against other income such as salary that year — it is quarantined, can be applied against certain residential capital gains, and otherwise carries forward: deferred, not lost. The test is worked out across your residential dwellings together rather than property by property, so a positively geared property in the portfolio affects the outcome. Amounts relating to an ownership interest last acquired before 7.30 pm (legal time in the ACT) on 12 May 2026 are disregarded. The full mechanics — including the contract-date rule for grandfathered interests and the pending new-dwelling instrument — are on our dedicated resource, Negative gearing changes from 2027–28, linked below.

Recordkeeping is what separates a defensible portfolio from a stressful year-end. As properties multiply, so do the loan splits, settlement statements, depreciation schedules, agent statements, insurance and council documents — and the longer those sit unfiled, the harder the year-end return and any future CGT calculation become. The discipline is to keep each property in its own folder from settlement, record loan purpose at drawdown, retain capital improvement records for the eventual cost base, and reconcile rental statements as they arrive rather than in a year-end scramble. A consistent structure across every property makes the return short, supports the deductions claimed, and means the eventual sale calculation is already half-built.
