Choose an investment property in Sydney by working backwards from the numbers: what you can borrow and hold, the rent against the holding costs, how easily it will rent and resell, and how a lender will value and finance it. Within your budget, the property type, its holding costs and its finance terms usually decide more than the suburb.

Since the 2026 Federal Budget, new or established matters too, because the tax treatment differs for purchases made after 12 May 2026.

What can you borrow and hold?

The price range comes from your borrowing power and your appetite for holding costs, not from a suburb list. Run the purchase through the borrowing power calculator, then budget the shortfall between rent and costs each month. A property you can comfortably hold through a vacancy or a rate rise is a better investment than a stretch purchase you have to sell at the wrong time. The investment property deposit guide sets out the cash or equity needed.

Yield or growth: what are you buying it for?

Decide which matters more to you, because most Sydney properties trade one against the other. Rental yield, the annual rent as a percentage of the price, is usually higher on units and further from the city, and helps cash flow; capital growth tends to favour land in established suburbs with lasting demand. Use the rental yield calculator on every shortlisted property so you compare like with like, after costs.

New or established, after the 2026 tax changes?

For residential property bought after 7:30pm AEST on 12 May 2026, negative gearing is limited to new builds from 1 July 2027. An established property bought after that time can be negatively geared until 30 June 2027; after that its losses only offset residential rental income and capital gains, with any excess carried forward. Capital gains accruing after 1 July 2027 move from the 50 per cent discount to cost base indexation with a 30 per cent minimum tax, and new-build investors can choose between the two. Properties held before Budget night keep negative gearing; the capital gains change applies to them too, but only to the part of a gain that accrues after 1 July 2027. The negative gearing guide covers the detail. In practice:

  • An established property now needs to stack up more on rent and growth, with less reliance on a tax loss.
  • A new build keeps negative gearing, but lenders value new stock conservatively, and off-the-plan buyers carry valuation risk at completion. See the off-the-plan guide.

Have your accountant model both before you choose.

What will a lender finance?

  • Small apartments. Many lenders restrict loans on units under about 50 square metres internally, or lend less against them. The small apartment guide explains the limits.
  • High-density and concentration limits. Some lenders cap their exposure in particular buildings or postcodes.
  • Serviced and short-stay properties have narrower lender lists and lower lending limits. See serviced apartment loans.
  • Valuation. The lender lends on its valuer’s figure, not the price you agree. Overpaying shows up here first.

Check these before you make an offer, not after.

What checks should you run on every shortlisted property?

  1. Rent evidence: recent leases for comparable properties nearby, not an asking rent.
  2. Holding costs: strata levies, council and water rates, land tax, insurance, management fees and maintenance.
  3. Strata health: the sinking fund, special levies and defect history, from the strata report.
  4. Tenant demand: transport, schools, employment and how long similar properties sit vacant.
  5. Supply: large approved developments nearby that could add competing rentals.
  6. Building and pest: the same inspection you would get for your own home.
  7. Resale appeal: would an owner-occupier want it as well as a tenant? That widens your buyer pool later.

Why structure the loan before you buy?

How the purchase is funded affects tax and future borrowing: whether equity is drawn as a separate loan, whether the loan is interest-only, and which lender holds which loan. The investment loans guide and the guide to using equity explain the common structures.

A side-by-side example: unit or house

Two illustrative properties at the 6 per cent example rate, each bought with an 80 per cent loan:

Gross and net yield, illustrative figures
Two-bedroom unit Three-bedroom house
Price $650,000 $1,200,000
Rent $650 a week, $33,800 a year $850 a week, $44,200 a year
Gross yield 5.2 per cent 3.7 per cent
Strata, council and water About $7,000 a year About $4,400 a year
Net yield before interest About 4.1 per cent About 3.3 per cent

The unit pays its way more readily; the house holds more land, which is where long-run growth has tended to come from in Sydney. Neither is the right answer on its own; the right one is the one you can hold through vacancies and rate rises while it does what you bought it for.

What does holding the property cost each month?

On the unit, an interest-only loan of $520,000 costs about $2,600 a month at the example rate against rent of about $2,817 a month, before strata, rates, insurance, maintenance and vacancies. After those, most Sydney investment purchases at today’s prices cost the owner something each month. Know that figure before you buy, and keep a buffer of several months of it.

What are the red flags on a shortlisted property?

  • Special levies or a thin sinking fund in the strata report.
  • Floor area under 50 square metres, which narrows the lender list and can lower the loan-to-value ratio. See small apartment loans.
  • High-density postcodes where some lenders cap their exposure.
  • Flood or bushfire overlays that raise insurance costs.
  • A rent that relies on short-stay letting, which lenders count cautiously or not at all.
  • A long run of the same new units in one building, which can soften valuations at completion.

What should you check before you make an offer?

  1. Two rental appraisals from local property managers, not the selling agent alone.
  2. Recent comparable sales in the same street or building, to sense-check the price and the likely valuation.
  3. The strata report for any unit or townhouse: levies, the sinking fund, special levies and defects.
  4. A building and pest inspection, with the cost of any repairs priced before you offer.
  5. An insurance quote, especially near bushland or flood-prone land.
  6. A lender check on the property itself: size, postcode and building type, before your offer depends on the loan.

Running these on every shortlisted property takes a week or two. It is the cheapest protection an investor has.

Questions people ask

Is it better to buy a house or a unit as an investment in Sydney?

Neither in general: houses usually offer more land and growth potential at a lower yield, while units usually offer higher yield and lower entry prices with strata costs. Compare both on yield after costs and on what lenders will finance.

What is a good rental yield in Sydney?

There is no single figure, because yields vary heavily with property type and location. Calculate gross and net yield on each property with the rental yield calculator and compare properties against each other, not against a single benchmark.

Can I still negatively gear an established property?

Yes, if you held it before 7:30pm AEST on 12 May 2026. If you buy after that time, only until 30 June 2027; after that the losses offset residential rental income and capital gains only.

Should I buy off the plan as an investment?

It can work: new builds keep negative gearing, but off-the-plan purchases carry valuation risk at completion and lenders treat some new stock cautiously. Check the lender position and your deposit before signing.

Do I need a buyer’s agent?

Not necessarily. Some investors use one to find and negotiate. Either way, check the finance and lender limits for the property type before committing.
