Yesterday I walked into a home in Bedfordale.
The automated valuation system — the one most homeowners check online before they make any decision — said the property was worth somewhere between $1.2 million and $1.3 million.
By the time I’d finished my appraisal, the figure I gave the owners was $1.8 million to $2 million.
That’s not a small gap. That’s not “the algorithm was a bit off.” That’s the algorithm being wrong by roughly half a million dollars on a single home.
And it happens all the time.
After more than two decades of selling property across the Perth Hills — Bedfordale, Roleystone, Kelmscott, Mount Nasura, Mount Richon, Seville Grove — I can tell you the question I get asked most often is some version of: “What’s my home really worth?”
The honest answer is that there is no single number. Your property’s value is the result of a long list of factors, most of which the algorithms can’t see, most of which sellers don’t know to look at, and most of which the average agent won’t tell you about.
This article is about those factors. The ones that actually move the price up or down. The ones that determine whether you walk away with what your home is genuinely worth, or whether you leave six figures on the table.
It’s also about something most sellers never think about — the difference between an appraisal that flatters you and an appraisal that’s honest with you. Because at the end of every campaign, only one of those leads to the right outcome.
Let’s get into it.
What Actually Happens in the First 60 Seconds of an Appraisal
Most articles on this topic say agents look at “comparable sales” or “land size” first. That’s not what happens.
The appraisal starts before I even get out of the car.
I drive up to the home and look at the street appeal. Has the front been maintained? What does the roof look like — do the tiles need work, is the ridge capping cracked, are the gutters rusted? Has it been freshly painted recently or is the paint tired? Have the eaves
gone mouldy? These things are visible from the road and they tell me an enormous amount about the property before I’ve even walked through the door.
Then I step inside, and I’m going to be honest with you here because most agents won’t. The first thing I’m doing is asking whether the home smells.
It sounds funny, but you would be surprised how often this matters. People with pets, or people whose cooking habits involve a lot of certain spices, or households where things just haven’t been aired out properly — they don’t notice it anymore because they live there. But a buyer walking in for the first time absolutely notices, and most agents won’t tell you because they’re too frightened of offending you.
My job is to actually get you to a point where we can sell your home for the best possible price. Sometimes a blunt conversation right at the start is the difference between a good price and a great price. And there is a difference.
From there I’m looking at presentation. Is the house tired? Does it need a fresh coat of paint? Are lightbulbs missing? Is there clutter everywhere? How do the bathrooms and kitchen look — not whether they’re new, but whether they’re functional and clean? Are there small jobs around the place that have been left undone?
Every one of those things affects price. And every one of those things is fixable, often cheaply, if the owner is willing to do the work.
The price I’ll quote you depends partly on what you’re willing to address before we go to market — because once buyers see a home online, you don’t get a second chance at the first impression.
Why the Online Algorithms Get It So Wrong
Let’s go back to that Bedfordale home from yesterday.
The automated valuation system gave a figure between $1.2 and $1.3 million. My appraisal was $1.8 to $2 million. What did the algorithm miss?
A lot.
The square meterage was wrong on the system to start with. That’s not unusual — these systems pull from old council records or guess based on land size, and they get it wrong constantly. From there it just compounded:
The home had a wonderful three-phase powered workshop — significant value to the right buyer, completely invisible to an algorithm.
It had a beautiful playground-style pool, well presented and maintained.
It had views across public open space, down the valley, all the way to the coast. Algorithms can’t see views.
The kitchen was enormous — well beyond what you’d expect at that price point. Algorithms count rooms, not size or quality.
And the overall presentation was spot on. Light, bright, clean, well looked after. That doesn’t show up in any database.
This is why I tell every homeowner the same thing: an online estimate is a starting point at best, and a dangerous trap at worst. The algorithms work by averaging sales of nearby properties with similar bedrooms, bathrooms, and land size. They have no idea whether your home backs onto public open space or onto a busy road. They don’t know your kitchen was renovated three years ago. They don’t know whether the property is dead flat or sits on a steep slope that would cost a fortune to develop. They don’t know whether mains water is connected to your acreage block, which is rare in this area and matters enormously.
These tools can be 10%, 20%, sometimes 50% out either way. And the people who get hurt by that are the people who plan their next move based on those numbers.
Why Most Sellers Get Their Own Price Wrong
Here’s something I see constantly, and it’s worth being direct about because nobody else will tell you.
Most sellers who overprice their home aren’t doing it because they don’t understand the market. They’re doing it because they’re not looking at the home from a buyer’s point of view. They’re looking at it from the point of view of what they want to buy next.
They’ve worked out their budget. They’ve decided they want to move closer to the coast, or to a nicer suburb, or to a bigger home. To make that move work, they need, say, $1.5 million. So now in their head, $1.5 million is what their home is worth — because that’s what they need it to be.
Then friends come around and say “It’s an absolutely beautiful home, don’t let the real estate agent undersell you, stick to your price.” That’s not strategy. That’s hope. And hope has never been a strategy in real estate.
It gets worse from there. They go online and the automated valuation conveniently agrees with the number they want. Or they start looking at bridging finance, and if they’re borrowing less than 70% LVR, the bank will do a “desktop valuation” — basically taking the
agent’s word or the algorithm’s number and rubber-stamping it. At 50% LVR, the bank will tell them just about anything they want to hear to put the finance in place.
So now they’re emotionally and financially locked in to a price that has nothing to do with what their home is actually worth in the market. Here’s the hard truth: the real estate agent isn’t buying your home. The seller isn’t buying your home. The buyers are buying your home.
And if you list at a price the market won’t pay, what happens is you help every other home in the area sell before yours does. Buyers compare yours to what else is available, and they walk away saying “the one down the road is better value than this one.” That’s the most
painful way to spend a year trying to sell.
What Buyers Are Actually Doing in Their Heads
This part is going to be different from anything you’ve read elsewhere on property valuation, but stay with me, because it’s the most important section of this article.
What a buyer pays for your home has almost nothing to do with logic.
There are three parts of the human brain involved, and they work in this order:
The reptilian brain — the safety check.
When a buyer walks into a home, the very first thing happening is a primitive question: do I feel safe here? Could my family be safe here? Is there anything threatening about the space?
Most buyers walk into the kitchen first. They stand there. And in those first seconds, they’re making a fight-or-flight assessment of whether this is somewhere they could imagine themselves living. If the answer is no — for any reason, even reasons they can’t articulate — they’ve already made up their mind. They might walk through the rest of the house politely, but they’re not buying.
This is why presentation matters so much. A cluttered, dark, smelly, neglected home triggers the wrong response in the wrong part of the brain, and you’ve lost the buyer before they’ve even seen the bedrooms.
The mid-brain — hierarchy and prestige.
Once safety is established, the next layer kicks in. Can I see myself entertaining friends here? Is this the kind of home I’d want people to see me in?
This is the buyer mentally placing a barbecue on the deck, picturing friends arriving, imagining the comments they’d hear. “What a beautiful home. Imagine living up here in the hills.” If your home can let them rehearse that conversation in their head, you’re in the
buying zone.
The neocortex — justification after the sale.
This is the third stage, and it’s where most real estate agents get the whole process backwards.
The neocortex is the logical brain, and it gets activated only AFTER the buyer has decided emotionally to buy. Once friends start asking “you paid how much?”, the buyer needs justification — the playground pool, the workshop, the kitchen, the ducted air-conditioning, the walk-in robe, the ensuite.
A huge amount of real estate marketing is aimed at the neocortex — bullet lists of features, technical specifications, room dimensions. That stuff is for justification AFTER the sale, not for triggering the sale itself. Agents who lead their marketing with feature lists are talking to
the wrong part of the brain entirely.
The sale happens at the reptilian and mid-brain level. The features close it out. One more observation, and I’ll say it carefully because the point matters more than the framing: the buying decision in most family homes is heavily influenced by the woman in the household. And in my experience, women tend to put themselves last. They walk the home in this order: kitchen first, then the children’s bedrooms and bathroom, then the laundry, and finally — almost as an afterthought — the master bedroom.
Then outside, looking at the workshop, the pool, the space for kids, the lifestyle features. If your home doesn’t work for the family at those three checkpoints, the features list at the end won’t save it. And if the agent doesn’t understand any of this, they’re guessing.
The Truth About Renovations and Return on Investment
This came up yesterday at that same Bedfordale appraisal. The owners asked me whether they should put in a third bathroom upstairs, off a teenage retreat.
My answer is the rule I give every seller: if you’re going to stay in the home for the next 5 to 10 years and you’re going to use the third bathroom, then yes, build it. Get value out of it yourself.
If you’re going to be selling in the next 12 to 18 months, don’t bother. A bathroom build is going to cost you at least $30,000 and you won’t get extra money for it at sale.
The same logic applies to most major renovations. Expensive bathrooms and kitchens, swimming pools — if you’re about to sell, these are usually money pits. You won’t recover what you spend.
There’s one caveat: if your bathrooms or kitchen are so rundown that a buyer would need to renovate them immediately, then they ARE costing you money — because buyers are mentally subtracting the cost of those renovations from what they’d pay for the home. In that case, doing something is better than doing nothing. But if your bathrooms and kitchen are functional and clean, leave them alone.
So what should you actually spend money on before selling?
Paint. Dollar for dollar, fresh paint is the cheapest and highest-impact thing you can do. It lifts a tired home faster than anything else.
Lighting. The old fittings in most homes make them look darker. A pack of 10 downlights from Bunnings and an electrician to install them — maybe $1,000 total — will make your home feel modern, bright, and warm throughout. The difference is immediate.
Flooring. Not always essential, but if floors are worn or dated, replacing them isn’t always expensive and can dramatically lift the feel of the home.
Decluttering. This costs nothing and changes everything.
If your home is small and you don’t have a shed or garage to store excess belongings, take the smallest bedroom and turn it into a temporary storage room. We don’t need to photograph that room. Buyers understand — most of them are in exactly the same situation
when they move. Decluttering is the single most underrated thing a seller can do. It makes rooms feel bigger, lighter, and easier to imagine living in. And it costs you nothing but time.
Location Within the Suburb Matters More Than Most People Realise
Every property article you’ve ever read will tell you “location, location, location.” But almost none of them explain what that actually means at a street level.
A suburb isn’t one homogeneous market. It’s multiple markets sitting next to each other, often with significant price differences.
Let me give you two real examples from suburbs I work in every day.
Bedfordale. On the Wallangara side, you can have a 4-bedroom, 2-bathroom home on 2 to 3 acres that’s worth around $1.4 million. Cross Albany Highway to the newer estates — Churchman Brook Estate or Waterwheel Ridge — and the same 4×2 layout on a 3,000 to
4,000 square metre block is worth around $1.8 million.
Same number of bedrooms. Same number of bathrooms. Smaller block of land. Higher price. Why? Because the newer estates have different infrastructure, scheme water, different buyer demographics, easier access. The Wallangara side is acreage with bore water and a
different lifestyle entirely. They’re different markets, and buyers approach them differently.
Mount Nasura. A 4-bedroom home at the bottom end of the suburb, near Albany Highway, will sell for around $1 million. Move that same home to the top of Mount Nasura — Rushton Terrace, Blackwood Drive — and it’s worth around $1.5 to $1.6 million. Same home. Different street. $500,000 difference.
This is why an algorithm averaging sales across “Mount Nasura” or “Bedfordale” will get it badly wrong on either side of the spectrum. The data points exist, but the algorithm treats them as one market when they’re really four or five.
A local specialist knows which pocket of the suburb your home sits in, which buyers are likely to be looking there, and what genuine comparable sales actually apply to your property. That’s the part you can’t get from a website.
What Happens When You Overprice — and Why “Negotiating
Down” Is a Trap
Sellers and a lot of agents think that listing high gives “room to negotiate down.” Here’s what actually happens.
The rule of thumb in real estate is that if you’re not within 5% of where the market deems your property to be priced, you’ll get very few enquiries — and if you’re 15 to 20% over the market, you’ll get almost no genuine offers.
Yes, you’ll hear stories about someone who got lucky and an over-market price stuck. But luck isn’t a strategy. 99.9% of the time, the over-priced home sits. So 30 to 40 days in, the agent suggests a price reduction. Let’s say 5%. Now you’re only 10-15% over the market. Same problem. The market knows you’ve adjusted, so they’re
watching you, but you’re still not in the buying zone. The reports that good agents can show you will tell you how many buyers have saved your property on portal websites — a strong signal that they like the home but don’t see the value at the current price.
Another three or four weeks pass. You’re at 60 days. You drop the price again.
Now everyone’s seen the home online for two months. There are websites — old-listings- style tracking services — that record listing history. Buyers actively use them to identify aged listings and negotiate harder, because they know how long you’ve been on the market.
And then there’s the negotiation trap. If your “strategy” was to list high and negotiate down, what you’re actually doing is negotiating with one buyer in isolation, with no competition from other buyers.
Here’s how it typically plays out:
You’re asking $1.2 million
The buyer offers $1 million
You meet in the middle at $1.1 million
They counter $1.05 million
You meet at $1.025 million
Each round halves your position. That’s a brutal way to sell a home — and it doesn’t account for the stress, the time, the months of keeping the home immaculate for inspections, th disruption to family life.
It gets worse in a declining market. If you’ve been on the market for 60 to 90 days and prices have dropped another 5%, you now probably have to drop a further 10% below true market value just to get people interested again. Overpricing in a falling market doesn’t just delay your sale — it compounds your losses.
The lesson is simple. The first 30 days of a campaign are when your property is freshest, most-watched, and most able to generate genuine competition. Waste them at the wrong price and you can’t get them back.
Marketing — and What 10-15% Looks Like in Real Money
How much of the final sale price is driven by HOW the home is marketed, versus WHAT the home actually is?
Honest answer: if your agent doesn’t understand the rules around marketing, or thinks marketing is a waste of money and a few iPhone photos thrown online will do the job, you’re going to leave 10 to 15% of your home’s value on the table. At minimum.
On a $1.2 million home, that’s $120,000 to $180,000. On a $1.8 million home, it’s $180,000 to $270,000. That’s not small money. That’s family-changing money. Here’s why. Almost every buyer in 2026 starts their search online, and the first thing they do is compare your home to every other home for sale in your suburb. If your photos are bad — dark, grainy, badly framed — they scroll past in under three seconds.
You don’t walk into a beautiful hotel or a new display home and find the lights switched off. The same logic applies to your home when you’re selling. It needs to be light and bright in every single photo.
The biggest thing most sellers miss is video. A proper video walkthrough — with the agent describing what the home is like and what makes it special — does what photos can’t. It lets buyers experience the home before they ever step inside.
The other thing most sellers don’t think about is the floor plan. Not a photocopy of something thrown together on the agent’s iPad. A properly drawn floor plan that shows bedrooms with furniture in them, living areas with sofas, the family room with the TV in
place.
Why does this matter? Because I’ve personally listened to buyers walk through a home with a good floor plan brochure and say “Mary can have this bedroom, John can have this one. We could put the wall unit here. The TV can go over there.”
That buyer has just bought the house. They’ve placed their belongings in it mentally. Everything from that point is just bringing the deal together. The brochure itself should be on cardboard, not paper run off the agent’s inkjet at home. When buyers walk away with a quality brochure, the home stays with them.
Miss these elements and you don’t get maximum competition between buyers. And here is the line every seller should remember:
You don’t get the best price for your home in isolation. You get it with competition between buyers wanting your home.
That’s the entire job of marketing. Not to “expose” your home to the market. To create competition between buyers who want it.
The Hardest Truth — Choosing Your Agent
I’m going to be direct with you here because this is the part where most sellers get it wrong.
In Western Australia, becoming a registered real estate representative takes an 8 to 10 day course. That’s it. After 8-10 days, someone is qualified to sell your family home — your biggest financial asset — and most offices then hand them a desk and a phone and say “good luck.”
Of the 1,800 to 2,000 agents trained in WA each year, only about 5 are still in the industry by the end of Year 1. After 5 years, only 2 or 3 of those are left. This is a hard business if you’re not willing to keep working at it.
So the real question isn’t whether your agent is registered. It’s whether they’re any good.
And here’s a brutal truth that sellers don’t hear often enough: there’s a big difference between “20 years of real estate experience” and “1 year of experience repeated 20 times.”
Plenty of agents got their registration, learned the basics in their first 12 months, and have done no real training since. They’re not better than the 5-year agent who’s been studying their craft. They’re just older.
The psychology and the emotional side of real estate — the three-brain stuff we talked about, the buyer behaviour, the negotiation skills — these are things any decent agent should be trained in. Not “maybe if I have time.” Must.
I still train every morning. I’m reading something or listening to something that makes me sharper, gives me an edge in the marketplace, helps me get my clients a better price. The day I stop doing that is the day my clients start losing money. Most sellers pick the agent who quotes them the highest price. That’s the single most expensive mistake you can make. Because the agent who told you what you wanted to hear at the appraisal is the same agent who’ll be sitting in front of you in 90 days, telling you to drop your price because “the market has changed.”
Before you choose an agent, ask each one these questions and compare the answers carefully:
1. What evidence are you using to support your price recommendation? Look for recent comparable sales, active competition, buyer enquiry levels, real market data — not opinions.
2. How will your strategy create competition between buyers? Exposure alone doesn’t create premium prices. Competition does.
3. How many of your recent listings have actually sold using the method you’re recommending for my property?
4. If your recommended price or strategy doesn’t work, what’s the plan?
5. What do you think buyers will dislike about my property — and what’s your plan to overcome those objections?
6. If this was your own home, would you use the same strategy you’re recommending to me? The answer should be immediate and confident.
7. What happens if the first two weeks don’t go to plan? Ask for a specific answer, not a vague one. The first two weeks are critical.
8. What is the biggest mistake sellers are making in today’s market? This reveals how well the agent understands current conditions.
9. What are you going to do differently that could help me achieve a better result than other agents? Look for a genuine strategy, not promises about photos, advertising, or company size.
10. What training have you done recently — and who have you been mentored by — to keep improving your craft?
The best agents focus on your outcome. Not their awards. Not their office size. Not their personal brand. Your outcome.
And ask yourself this question — the one that matters more than any of the others: Is this the person I want sitting in front of me at the final negotiation, telling me this is the most I’m going to get for my home?
If you can’t trust that they’ll tell you the truth at that moment — the moment that decides everything — then don’t pick them. It’s that simple.
Friendliness is not a substitute for capability. Likability is not a substitute for honesty. The agent who tells you only what you want to hear at the appraisal is the same agent who’ll fail you at the negotiation.
The Bottom Line
Your property’s appraisal value isn’t a single number that comes out of a database. It’s the product of dozens of factors — many of which the algorithms can’t see, most of which the average agent won’t talk about honestly, and all of which add up to either the right outcome or six figures left on the table.
The street appeal. The smell. The presentation. The renovations you do or don’t do. Which pocket of the suburb you sit in. The pricing strategy you choose. The marketing investment.
The buyer psychology you trigger or fail to trigger. The agent you choose to handle all of it.
Every one of those things either adds to your price or takes from it.
If you take one thing away from this article, take this: You don’t get the best price for your home in isolation. You get it with competition between buyers wanting your home. Everything else — the appraisal, the presentation, the marketing, the strategy, the agent you choose — is in service of building that competition.
And the agent you trust to build it for you is the one who’ll be sitting opposite you at the end, telling you the truth about the offer in front of you. Pick the one you trust to do that.
If you’re thinking about selling in Bedfordale, Roleystone, Kelmscott, Mount Nasura, Mount Richon or Seville Grove, I’d be happy to come and give you an honest appraisal. No pressure, no obligation, no game-playing.
Just a real conversation about what your home is genuinely worth in today’s market, and what we’d do to maximise it.
