Perth Rental Market: Suburbs with the Lowest Vacancy Rates for Property Investors
If you are considering an investment property in Perth, the question that matters are where rental demand is strongest and which suburbs give you the best chance of securing a tenant quickly. Perth's citywide vacancy rate answers part of that question, but suburb level data tells a much more useful story.
Perth's metro vacancy rate is sitting at roughly 0.5%, according to SQM Research, a fraction of the 2.5% to 3.5% range REIWA considers a balanced market. That tightness is not evenly spread. Some suburbs are tighter still, others carry more supply risk than the citywide figure suggests, and price and yield vary considerably across the suburbs with the strongest tenant demand.
This article works through where Perth's vacancy rate is lowest, what that means for an investor, and how to combine vacancy data with price, yield and supply before deciding where to buy. Data current as of April 2026 unless otherwise noted.
What's Happening in the Perth Rental Market
Perth's rental market closed 2025 at record levels and has stayed tight into 2026. REIWA data puts the median house sale price at around $845,000 as of April 2026, with a weekly median rent of $700, putting gross yield on houses at roughly 4.3%.
Units are cheaper to enter and yielding more. The median unit price sits near $595,000 with weekly rents around $670, a gross yield closer to 5.9%. Annual growth has been strong across both property types, with Cotality recording 24.1% growth for houses and 26.1% for units over the year to March 2026.

Supply remains the constraint behind all of this. Listings are running roughly 40 to 45% below the five-year average, and properties are leasing in around 14 days on houses. Around 35% of West Australian households are now considered to be in rental stress, spending more than 30% of gross income on rent, up from 28% in 2022, a signal that affordability is starting to push against how much further rents can climb in some areas.
What Perth's Vacancy Rate Actually Tells Investors
Vacancy rate measures the share of rental properties currently listed and available against total rental stock in an area. REIWA treats a rate between 2.5% and 3.5% as a balanced market, where tenants and landlords have roughly equal negotiating power.

A tight vacancy rate is a genuine demand signal, but it is a point in time measurement, not a guarantee. It tells you tenants are competing for stock today. It does not tell you what purchase price you are paying for that demand, what yield you will achieve, or whether a wave of new supply is about to change the picture in a given suburb.
Which Perth Suburbs Have the Lowest Vacancy Rates
Affordable, family-oriented suburbs on the city's southern and southeastern fringe are consistently among the tightest in Perth. Armadale, Rockingham and Baldivis all combine sustained low vacancy with yields above the citywide house median.

The common thread across these suburbs is affordability paired with genuine tenant demand drivers, schools, transport and employment access, rather than low vacancy sitting in isolation. Premium suburbs such as Dalkeith, Cottesloe and City Beach can also run tight, but their yields typically compress to around 2.3% to 2.5% because purchase prices have grown faster than achievable rents.
Does Low Vacancy Mean a Good Investment
Low vacancy genuinely benefits landlords. It reduces the risk of an extended vacancy between tenants, supports rental pricing power, and tends to produce more consistent income than a suburb with looser conditions.
Vacancy rate: A useful demand signal, best read alongside how long that tightness has held rather than as a single snapshot.
Median property price: Sets your entry cost and deposit requirement and should be checked against the suburb median rather than a citywide average.
Weekly rent: Determines your actual income, and is worth comparing against comparable properties rather than a suburb wide average alone.
Gross rental yield: Combines price and rent into one comparable figure across suburbs, though it ignores holding costs and should not be read in isolation either.
Capital growth trajectory: Reflects whether the suburb has genuine demand drivers, population, employment, infrastructure, behind its recent performance.
How to Compare Perth Suburbs Before You Buy
Start with rental demand and vacancy, then weigh that against what you are paying to access it. A suburb yielding 6% at an affordable entry price and consistently tight vacancy is a different proposition to a suburb yielding the same figure purely because prices have not moved. Our guide to how to read a suburb profile walks through that comparison process in more detail.
Supply pipeline matters as much as today's vacancy figure. A suburb with land still being released, or a wave of new apartment stock approved nearby, can see vacancy loosen considerably within a couple of years, even if today's number looks exceptionally tight.
Long term growth fundamentals, population growth, employment access, transport and infrastructure, determine whether today's tenant demand is durable. Our broader look at which suburbs have the strongest capital growth in Australia covers how those fundamentals show up in the data nationally, not just in Perth.
Is Perth Still a Good Market for Investors?
Perth's rental demand remains a genuine consideration for investors, but the market is not static. REIWA's 2026 forecast points to continued but more measured growth, house prices up more than 10% and units 15% to 20%, with vacancy expected to stay below balanced levels in inner and middle ring suburbs specifically. For a broader comparison against another major investment market, our Perth versus Brisbane property market analysis looks at how the two cities compare on fundamentals.
What could change this picture over the next 12 months includes new supply finally landing in growth corridors, interest rate movements affecting both buyer and investor demand, and rental affordability limits, given 35% of WA households are already in rental stress, capping how much further rents can realistically climb in some suburbs.
Researching Perth's Rental Market as an Interstate Investor
Do not choose a Perth suburb on vacancy rate alone if you are buying from interstate. Research the local tenant profile, whether a suburb leans toward families, FIFO workers or younger renters, since that shapes what kind of property performs.
Comparing a suburb against its immediate neighbours matters too, since vacancy and yield can vary meaningfully between adjoining postcodes. Our guide to university towns with strong vacancy rates covers a similar comparison exercise in a different market context if that is useful background.
Your borrowing position often narrows the field before suburb comparison even starts. Understanding home loan borrowing capacity helps set a realistic budget before you fall in love with a suburb that is not actually accessible. Our Property Investment Australia hub covers the broader strategy questions worth working through alongside the Perth specific research.
Final Thoughts
Low vacancy is a genuinely useful indicator of rental demand, and Perth's citywide figure of around 0.5% confirms the market remains tight overall. The strongest investment decision comes from combining that vacancy signal with price, yield, supply and long-term growth fundamentals rather than treating a low number as the whole story.
Suburbs such as Baldivis, Rockingham and Armadale currently combine tight vacancy with yields above the Perth house median, which is a more complete signal than vacancy alone. Working through that fuller picture, rather than chasing the single lowest vacancy figure, is what separates a considered purchase from a guess.

Most investors are still positioned in capital cities — but in 2026, that allocation gap is creating real opportunity cost. In a market where timing, positioning, and yield profiles compound into long-term outcomes, that disconnect matters more than most people realize.
