With global uncertainty rattling financial markets and petrol prices climbing again, Australia's housing market is heading into a period where every dollar counts. For buyers, the question is no longer just whether to buy, but how to buy smarter.
We went back to basics. Over five years and more than 1.6 million residential house sales later, we ran the numbers across every variable we could find: suburb, land size, build year, etc. Most of what we tested confirmed what buyers already know. But one variable kept surfacing that nobody seemed to talk about.
It's on the front of every house. The number.
As house numbers increase, so does the median house price. House numbers 1–20 cluster around the $940K to $960K mark, whereas house numbers 80–100 don’t go lower than $966K with many houses with higher numbers passing $1 million.
In other words, buyers at the higher end of the street are paying a premium they don't even know about. But flip that around and it's one of the easiest discounts in the market, houses with lower numbers consistently sit below the median. No negotiation. No renovation. No buyer's agent. Just a smaller number on the letterbox.
We know this sounds like an April Fool's Day joke, and we wanted it to be, but the data is real. The house number itself isn't driving the price. Longer streets tend to sit in older, more established suburbs where land values are already higher. So a house numbered 85 isn't worth more because of the number, it's worth more because of where that number tends to exist.
