Fred Harrison famously warned of the property downturn that followed the 2007 market peak. His next prediction? UK property prices would peak in 2026 before entering another downturn.
We're now approaching November 2026, and there's something interesting about how the market has performed.
Despite higher mortgage rates, political uncertainty and years of negative economic headlines, property prices have continued to show resilience in many parts of the UK.
So, is Harrison's famous 18-year property cycle still working, or has something fundamentally changed?
What is supposed to happen before the property market crashes?
Harrison's theory isn't simply that property prices crash every 18 years.
It describes an initial period of recovery and steady growth, followed by a mid-cycle slowdown, before the market enters a stronger phase of expansion.
Towards the end, speculation intensifies, borrowing increases and property prices accelerate, eventually reaching unsustainable levels.
That's when the correction follows.
But look at the last few years.
According to the latest HM Land Registry figures, average UK property prices increased by 0.9% in the year to August 2026. However, this national average masks significant regional differences, with some areas recording stronger growth while others experienced price declines.
Rather than the widespread speculative acceleration traditionally associated with the final stages of the cycle, we've experienced higher borrowing costs, affordability pressures and relatively modest national price growth.
So where is the final speculative boom that Harrison's theory would lead us to expect?
Why hasn't the property market followed the expected pattern?
The last few years have been anything but typical.
The pandemic brought exceptionally low borrowing costs, government incentives and a surge in housing demand. That was followed by rising inflation, fuelled partly by the war in Ukraine and, more recently, conflict in the Middle East. These geopolitical shocks pushed up energy and other costs without a corresponding increase in economic growth, while higher interest rates placed further pressure on mortgage affordability.
Yet despite these pressures, parts of the property market have continued to demonstrate resilience, particularly in locations with strong underlying demand and where homes remain affordable to owner-occupiers.
Rather than a consistent nationwide acceleration towards 2026, we've seen a more measured and increasingly selective market.
This raises an interesting possibility: have the extraordinary economic conditions of recent years disrupted the traditional cycle, making its timing less predictable?
It doesn't mean another downturn is impossible, but neither should we assume one is inevitable simply because the calendar has reached a particular year.
So, is Fred Harrison's 18-year property cycle broken?
It's too early to say.
Harrison predicted a property peak in 2026, not necessarily a crash before the year was over. And with the full year's transaction data still unavailable, his forecast cannot yet be judged conclusively.
However, the expected speculative build-up hasn't unfolded in the way many might have anticipated.
And for property investors, the last four years have reinforced something equally interesting.
Even during challenging economic conditions, some locations have continued to deliver capital growth and rental demand, while others have struggled.
Rather than trying to predict exactly when the national property cycle will turn, investors may benefit more from understanding where employment, housing demand, affordability and infrastructure are supporting individual markets.
It's also worth considering who will eventually buy the property. A location that appeals to both investors and owner-occupiers may offer a broader resale market than one dependent almost entirely on investor demand.
After all, you don't invest in the national average. You invest in a particular property, in a particular location, at a particular price.
And getting those decisions right may prove far more valuable than predicting the exact year of the next property downturn.
