Why do two similar houses in the same street sell for different prices?

Houses that look the same from the footpath rarely are. They differ in condition, position, land and presentation, and they sell on different days, to different buyers, on different terms. Add what those buyers could borrow, and a gap of tens of thousands of dollars between neighbours is normal. It doesn't prove one sale was wrong.

Here's an example only, with made up figures. Number 12 sells for $1,150,000. Number 18, same street and same bedroom count, sells six weeks later for $1,060,000. The owner of number 18 wants to know what went wrong.

Often, nothing did.

Two houses in a row are like twins in matching jumpers. From across the road you'd swear they're identical, and then you spend ten minutes inside and notice they're nothing alike. If you've been following property value Perth results street by street, you've seen the same thing in real life. It's early November, late spring, and plenty of owners are asking the question right now. Here's where the gap usually comes from.

The houses are less alike than they look

1. Condition and the work nobody sees

One house has a new roof and a clean pest report, while the other has an old fuse box, a damp patch behind a wardrobe and a termite treatment nobody can find paperwork for. A buyer rarely spots any of that on the day, but their building inspector will before the contract goes unconditional, and the price moves to match.

Paperwork matters. Receipts are worth money.

2. Renovations, good and bad

A renovation helps only when buyers like what was done. A tidy, neutral kitchen adds comfort and starts no arguments. A bold one in someone's personal taste can make buyers subtract the cost of ripping it out. Cheap work shows too, in wonky tiling, paint on the hinges and a bathroom done on a budget. Buyers tend to pay for finish more than for features.

3. Layout and the way it feels

Same floor area, different feel. One plan runs from the front door to the kitchen to the yard in a straight line. The other has a hallway that swallows ten square metres and a kitchen you reach through a bedroom. Buyers can't always say why one feels bigger. They just pay more for it.

Do you notice a good layout when you live in it? Mostly not, which is why owners undervalue theirs.

What to compare, room by room

• Age and condition of the roof, wiring and plumbing

• Kitchen and bathroom quality of finish

• Number and size of bedrooms

• How the living areas connect to the yard

• Storage, parking and extras such as a pool or shed

• Paperwork, warranties and approvals

Position on the street and the shape of the land

1. Where on the street it sits

Numbers 12 and 18 might be six doors apart, yet one sits near a busy intersection and the other mid street. A corner block cuts either way, with more light and room for a second entrance on one side and more traffic noise and less privacy on the other. The quiet end of a cul-de-sac often gets a premium, and a house facing a main road such as Canning Highway usually takes a discount because the front rooms hear traffic all day.

2. Land size, slope and easements

Two titles of 450 square metres can behave like two different sizes. One is flat and square. The other slopes toward the back fence and carries a drainage easement along one side, which limits where a pool, a shed or an extension can go. Slope costs money. Buyers also ask whether the land could be subdivided under the council's current rules, and those rules change, so a buyer who wants that answer should check with the council and not trust a listing.

3. Aspect and what's next door

In Perth, north facing living areas catch the winter sun, while west facing glass can cook in summer without shade. The neighbours matter too. A two storey extension looking into the yard, a garage wall at the fence or a leafy garden that adds privacy all change how a backyard feels. It's squishy and hard to price, and buyers do it every time anyway.

Presentation and how the sale was run

1. The photos and the first weekend

Plenty of buyers meet a home on a phone first. Bright and straight earns a tap, and dark and cluttered earns a scroll. The first weekend matters because that's when the most buyers show up. A listing that launches with weak photos and a vague description can burn its best chance and spend weeks trying to win it back.

2. Price guide and sale method

Some Perth homes sell by private treaty with a price guide, some by auction and some by expressions of interest. Guides set the crowd. Set it too high and the right buyers stay away, and set it too low and you draw a crowd that won't pay beyond what they can see nearby. A guide built on three recent sales usually does better than a hopeful one, and a price gap between neighbours isn't proof one agent did a better job, because the two may have been chasing different buyers altogether.

3. The campaign behind the sign

Good photos, a clear floor plan, a straight description, open homes and real follow up calls make a full campaign. Some sellers get all of it. Others get half. If you want to check an agent before you list, look up their licence on the Consumer Protection WA website, and ask to see the campaign plan in writing.

Campaign checks

• Quality of photos and floor plan

• How the price was guided

• Sale method and why it was chosen

• Number of open homes and enquiries

• Days on market and any price changes

• Follow up with interested buyers

Timing and competition on the day

1. Who else was selling

When three similar homes list in the same month, buyers compare and pick. The first to launch often gets the strongest interest, and the third inherits the leftovers. Look at what else was on the market the week your neighbour sold.

2. Interest rates and the season

Rates move. Borrowing power moves with them, so a rate rise cuts what a buyer can borrow and the price they can reach drops, while a rate cut does the reverse. These swings pull property value Perth results around from month to month, and two sales six weeks apart can land in quite different conditions. Spring is usually the busiest listing season in Perth, which gives buyers more choice and gives sellers more rivals.

3. How many buyers turned up

A second keen buyer is worth more than any appraisal. That's our view, and we'd stand by it. When two people want the same house, the price becomes a contest. When one person wants it, the price becomes a negotiation, and negotiations tend to end lower.

Did number 18 have fewer bidders, or just the wrong ones? From the outside you often can't tell.

• Similar homes listed the same month

• Season and school term dates

The buyer and the terms

1. Owner occupier, investor or builder

Owner occupiers pay for how a home feels. Investors pay for rent. Builders pay for land and what the council allows them to build. Same house, three different numbers. If number 12 sold to a builder and number 18 to a first home buyer, the prices might be telling you about the buyers more than about the houses.

2. Deposit, finance and conditions

A clean offer with a big deposit and no conditions can beat a higher one wrapped in finance clauses. Sellers sometimes take less for more certainty. The headline price hides all of that, which is why two sales at the same figure can be very different deals.

3. Settlement date and what stayed behind

A long settlement suits a seller who needs time to find the next place, and a short one suits a cash buyer in a hurry. Items left in the house, such as a shed, a dishwasher or a set of curtains, nudge the final number too, and so do repairs agreed after the building report. Buyers rarely say any of this out loud, yet it moves the price by a few thousand dollars here and there.

• Type of buyer

• Deposit size and when it was paid

• Finance and inspection conditions

• Settlement length

• Inclusions and exclusions

• Repairs or credits agreed

How to work out what your own house is worth

1. Pull the sales and list the differences

Don't copy your neighbour. Pull three to five recent sales from Landgate or REIWA data, then write down every difference: land, condition, position, extras, sale date and method. Put a rough dollar figure on each one. Where you land is a range, not a single point. That's how buyers build property value Perth numbers for a street, and it's worth doing the same before you list or make an offer.

2. Use an agent's appraisal as a start

An appraisal is an agent's opinion of what your home is likely to sell for. Most agents do them for free, and ours are free and carry no obligation. Ask each agent to show the sales behind the figure, and to explain any gap between their number and the last sale on your street. Good agents are happy to be asked.

3. Know when you need a valuation

A valuation is a formal report from a licensed valuer, and it's the kind lenders, courts and the tax office accept. If you're refinancing, settling an estate or dealing with a family law matter, a property valuation Perth lenders will accept has to come from a licensed valuer, not an agent. For a sale, an appraisal is usually enough, though a valuer can help if you suspect the market has shifted. A property valuation Perth owners order carries a fee, so ask for quotes first.

Questions to ask

• Which sales are the closest match to my home?

• How did you adjust for land and condition?

• What would raise or lower your figure?

• How long did similar homes take to sell?

• Do I need an appraisal or a valuation for what I'm doing?

Conclusion

Neighbours can sell for different prices and both sales can be right. Before you judge your house against the one down the road, list the differences and put a dollar figure on each. If the gap still doesn't make sense, ask an agent to walk you through the sales, or book a licensed valuer if you need a formal property valuation Perth lenders and courts will accept. Either beats guessing.
