How Much Is My House Worth in Perth?

Your Perth home is worth a range, not a number. The honest answer is a band of roughly five to eight per cent, built on what genuinely comparable homes near you have sold for in the last three to six months. Anyone who hands you a single confident figure without seeing the property, and without showing you those sales, is either guessing or selling.

For context, the REIWA median house sale price across Perth metro is $960,000 for the twelve months to August 2026, with the median unit at $690,000. That is a citywide middle point. It tells you almost nothing about your house, and I would not want you making a decision on it.

What actually sets the price of your home

Four things do most of the work, in this order.

Comparable sales. Recent settled sales of homes that are genuinely like yours, in your suburb, ideally within a few streets. Not listings, not asking prices, not what your neighbour reckons they turned down. Settled sales, with dates.

The specifics of your block. Land size, zoning and subdivision potential, orientation, whether you back onto a park or a main road, the slope, the street. Two houses that look identical on a portal can be sixty thousand dollars apart because one has a north-facing rear yard and the other does not.

Condition and layout. Not whether it is tidy, but whether a buyer has to spend money on arrival. A functional kitchen and bathroom, a layout that works, no obvious structural work waiting. Buyers price repairs at what they fear it will cost, not what it actually costs.

What buyers are doing right now. Perth has been strong. REIWA recorded 5.3 per cent growth in the median house price in the March 2026 quarter and preliminary growth of 4.2 per cent in the June quarter. But the June quarter also saw new listings return to their longer-term averages and demand ease, with investors and first home buyers both stepping back. A rising market forgives a high price. A steadying one does not.

The three ways to get a number, and what each is worth

An online estimate. Free, instant, and a starting point at best. These tools run an algorithm over Landgate sales data and whatever attributes they hold about your property. They have never been inside your house. Run the same address through the same tool a fortnight apart and the number can move by a sum that would change your plans, on a property that has not physically changed at all. Perth's housing stock is unusually varied, from pre-1970 homes in the inner suburbs to nineties brick and tile to new builds on the fringe, and algorithms handle that badly. Use one to get oriented. Do not use one to plan.

An agent's appraisal. This is what I do, and it is free. It is an informed opinion from someone who is in these streets every week, has stood inside the homes that sold, and knows what the buyers who missed out were prepared to pay. It is not a regulated document and it cannot be used for a bank, the tax office or a court. Its value depends entirely on the honesty of the person giving it.

A licensed valuation. A certified valuer, licensed under the Land Valuers Licensing Act 1978 in Western Australia, inspects the property, analyses comparable sales and produces a written report with an assessed value at a specific date. It costs money. You need one for lending, capital gains tax, a deceased estate, a family law matter or a self-managed super fund. For a straightforward sale, you almost certainly do not need one, and I will tell you so rather than send you off to spend several hundred dollars for no reason.

Why the highest appraisal is the one to watch

Here is the part of this industry I will not defend. Some agents quote high to win the listing. It is the easiest sale in real estate, because you want the number to be true and there is no cost to them at the moment they say it.

The cost lands on you, four to eight weeks later. The home launches above the market, the first fortnight of buyer attention is spent and wasted, enquiry dries up, and then come the price conversations. By the time the price is corrected the listing is stale, buyers have watched it sit there, and it commonly sells for less than it would have if it had been priced properly on day one. You also carry the holding costs and the marketing spend for the extra weeks.

So when you collect appraisals, do not rank the agents by their number. Ask each one for the three to five sales the number is built on, with addresses and dates, and ask why each one is comparable to yours. The agent who can walk you through that, including the sales that do not flatter your house, is the one telling you the truth.

How to sanity-check a number yourself

• Pull the last three to six months of settled sales in your suburb for your property type and bedroom count. Recent matters more than plentiful.
• Strip out anything that is not really like yours: different land size, a better or worse street, a renovation you do not have.
• Look at what is currently listed and unsold near you, and how long it has been sitting. That is your competition, and it tells you where the ceiling is.
• Expect a range. If your working band is $880,000 to $930,000, that is a normal and healthy answer, not a failure to be precise.

Questions sellers ask

Is an agent appraisal the same as a valuation?
No. An appraisal is a real estate agent's opinion of likely selling price, given free, and it is not a regulated document. A valuation is a formal written assessment by a licensed valuer and is what banks, courts and the tax office accept. Two different jobs.

How accurate are online property estimates in Perth?
Directionally useful, individually unreliable. They cannot see your condition, layout, outlook or renovation, and their figure on a single property can swing significantly between updates. Treat one as a rough bracket, not a price.

Should I pay for a valuation before I sell?
Usually not. For an ordinary sale it is money spent on a document the buyer will never see. Pay for one when there is a formal reason: finance, tax, a deceased estate, a separation or a dispute between owners.

Does the Perth median house price tell me what my house is worth?
No. The $960,000 Perth metro median for the twelve months to August 2026 is a citywide midpoint across every suburb and every type of house. Your suburb and your street can sit a long way either side of it.

Should I get three appraisals?
Two or three is sensible, as long as you compare the evidence rather than the headline figures. If one number sits well above the others, that is a reason to ask harder questions, not a reason to list with that agent.

The honest summary

Getting the value of your Perth home right is not difficult, but it does ask you to want the real number more than you want the big one. Start with the recent settled sales near you, get two or three appraisals, and pick the agent on the evidence they showed you rather than the figure they led with. Price it properly and the market comes to you in the first fortnight, which is when the best offers happen. Price it on hope and you spend the next two months buying that lesson back.

If you want a straight answer on your own place, I will come out and give you a free appraisal, with the comparable sales laid out so you can see exactly how the number was built. If the honest answer is that now is not your moment to sell, I will tell you that too. I have advised on more than 700 Perth homes across 45 suburbs and sold over $350 million in property, and I would rather give you a real number than a flattering one.
