Quick Summary: Two houses on the same WA street can differ by hundreds of dollars a week in rent, so suburb averages alone will lead you to the wrong property. Run a fixed sequence: net yield first (a $600 a week Perth rental buying at $550,000 with $8,000 costs nets about 4.2%, while units showing 5-6% gross can fall under 3% net after strata fees), then strata and building condition, then WA legal and tenancy checks including land tax above $300,000, stamp duty and Residential Tenancy Act 1987 compliance. Score each deal with net yield at 30%, vacancy risk 25%, strata health 25% and land tax and duty 20%, and walk away or reprice if two checks fail. Choose your management model before you offer, since hidden fees quietly cut your net yield.
Two four-bedroom houses on the same WA street can rent hundreds of dollars a week apart. Compare suburb averages alone and you will buy the wrong one almost every time. Evaluating investment properties properly means running a fixed sequence of checks: yield, cashflow, compliance and location. This guide walks through each one for WA conditions. At Smart Realty, Mahi Masud has spent 20-plus years managing 1,800 properties, and this is the same property investment checklist we use.
Step 1: Test the Numbers Before You Fall in Love With the Address
Evaluating investment properties starts with the maths, not the suburb. Calculate net yield by subtracting every cost from annual rent, then dividing by the purchase price. For a Perth property renting at $600 a week, that is $31,200 a year. Take off rates, insurance, management fees and maintenance, say $8,000, and $23,200 on a $550,000 purchase gives roughly 4.2% net yield.
Gross yield versus net yield: the number most investors get wrong
Gross yield uses rent divided by price alone. Perth units often show 5-6% gross, which looks strong, but strata fees can drag the net figure below 3%. Always compare net yields, not headline rates.
Vacancy, days on market and the price of an empty month
Check the suburb’s rental vacancy rate and typical days on market before you buy. In WA, several Perth suburbs currently sit near 1% vacancy, while others run higher. One month empty each year cuts your net yield by close to half a percentage point, so budget for it. That is why we stress-test cashflow before recommending any purchase, a habit worth building when you plan a portfolio around cash flow.
Step 2: Run the WA Investment Checklist on the Building and the Street
The WA investment checklist has four ordered checks: yield, strata, condition and street-level demand. This step covers the last three.
Strata and owners corporation: where WA investors get burned
Before you buy a unit, run strata due diligence in Western Australia:
- Read the last 12 months of meeting minutes and the levy schedule
- Check the sinking fund balance against upcoming works
- Ask about pending special levies, defects and insurance claims
- Confirm bylaws allow your rental plan
High levies turn a strong gross yield into a weak net one.
Condition, services and street level reality
Order a building inspection and price the deferred maintenance it finds. Check the rental vacancy rate nearby, walk the street at night, and look at days on market for comparable listings. Cash flow shapes every Perth portfolio, so read how to build one around cash flow before you offer.
Step 3: Verify the Legal and Tenancy Position Under WA Law
Title, land tax and the true acquisition cost
Run a title search to confirm the owner, easements and encumbrances before you commit. WA charges land tax on land valued above $300,000 when it is not your home, so budget for it from day one. Add stamp duty to your investment property analysis, because duty changes your real entry cost and the yield you calculated in Step 1.
Setting the tenancy standard before you let
The Residential Tenancy Act 1987 governs leases, bonds, entry notice and repairs in WA, and breaches carry real penalties. Check smoke alarms, safety switches, pool barriers and any minimum standards before the first tenant moves in. Fix these now, because they cost far more once a tenancy has started.
Step 4: Score the Deal, Negotiate, and Plan for Management
Turn the evaluation into a score and an offer
| Check | Weight | Pass Signal |
|---|---|---|
| Net yield | 30% | Above 4% after all costs |
| Vacancy risk | 25% | Suburb vacancy under 2% |
| Strata and building health | 25% | Clean minutes, no deferred repairs |
| Land tax and duty impact | 20% | Cashflow survives a 2% rate rise |
Fail two weighted checks? Walk away or reprice the offer to match the risk.
Choosing a management model before settlement
Pick your management structure before the offer goes in, not after keys change hands. Compare property management fees in Perth against what each fee actually covers, because hidden charges quietly cut your net yield. Smart Realty runs an all-inclusive model with no hidden fees, so the yield you scored is the yield you keep. Confirm the manager knows the Residential Tenancy Act 1987 before you sign anything.

Q3: Does land tax apply to investment properties in WA?
Yes, on land valued above $300,000 that is not your home.
Conclusion
Evaluating investment properties in WA comes down to a fixed sequence: net yield first, then strata, condition, legal checks and vacancy risk. Run your investment property analysis in that order, score each deal, and walk away when two weighted checks fail. The maths protects you; disciplined habits keep your Perth portfolio profitable.
