Half of all homes across Great Britain are taking longer to sell than they were a year ago. That's the headline finding from a major new report by one of the leading property portals, and it paints a picture of a market under genuine pressure, shaped less by the familiar forces of supply and demand than by something altogether more turbulent: the ongoing Iran war and its destabilising effect on mortgage pricing.
For anyone selling, or thinking about selling, in Tonbridge and the surrounding area of Kent, the national picture offers useful context. But the local data is what really matters, and here in TN9 and its neighbouring postcodes, the numbers are stark.
What the National Picture Tells Us
The report found that homes in 180 out of 363 local authorities across England, Scotland and Wales were taking longer to sell compared with a year ago. The national average time to sell has held steady at 42 days, but that figure masks a widening gap between parts of the country where buyers are racing to complete and areas where a cautious, wait-and-see mood has taken hold.
Scotland is dominating the fast end of the scale. The ten quickest-selling markets in Britain are all north of the border, with Falkirk recording an average of just 11 days from listing to sale agreed. Carlisle and Barnsley, both at 23 days, are the fastest-moving English markets.
At the other end, eight local authorities are averaging two months or more to sell. Melton in the East Midlands leads that list at 76 days, followed by Westminster in London and Teignbridge in the south-west. These aren't failing markets necessarily, but they are markets where buyers have pulled back, reassessing what they can afford as mortgage rates move unpredictably beneath them.
The Mortgage Rate Effect Is Real and It's Biting
The catalyst for much of this is the Iran conflict, which has been rattling financial markets in ways that feed directly into home loan pricing. When the conflict escalated in March, several lenders pulled mortgage deals at short notice. The cost of a typical home loan surged as markets grew nervous about a fresh wave of global inflation and what that might mean for the Bank of England's rate-setting path.
According to figures from a leading financial data provider, the average two-year fixed residential mortgage rate stood at 5.61% as of mid-August. Before the conflict broke out at the end of February, that rate was 4.83%. It peaked at close to 6% in April. That's a meaningful increase in monthly repayments for anyone buying at Tonbridge price levels, and it goes a long way towards explaining why buyers are pausing.
The uncertainty hasn't gone away. The Iran situation continues to unfold, which means lenders and borrowers alike are operating without a reliable road map. Markets expect the Bank of England to weigh all of this carefully, but no decision has yet been announced, and the direction of travel remains genuinely unclear.
Tonbridge: A Local Market Under Its Own Pressure
Against that backdrop, the Tonbridge data deserves close attention. Across the 12 areas covered in this analysis, the average property price stands at £719,483. Price growth over the past year is flat, with a year-on-year change of 0.0%. That's not a crash, but it's not the kind of market where sellers can afford to be complacent about pricing or presentation.
The figure that stands out most sharply is the average days on market: 457 days. That is a very long time. Even accounting for the kinds of premium properties that naturally take longer to find the right buyer, an average of that magnitude tells you that a significant portion of stock in this area has been sitting without a buyer for well over a year. That's not a comfortable position for sellers, and it's a signal that asking prices across a number of listings are not aligned with what buyers are currently willing to pay.
The sold subject to contract rate, meanwhile, sits at 20%. One in five properties listed is progressing to a sale. That's a real conversion rate, and it shows there are active buyers in the market. But it also means four out of five listings are not yet achieving that outcome, which is a telling measure of how selective purchasers have become.
Why Kent Buyers Are Being Careful
Tonbridge sits in a part of Kent where the commuter premium is real. Buyers come here for the train links into London Bridge and Charing Cross, for the schools, for the green belt and the open countryside that begins almost at the edge of town. These are durable attractions, and they haven't gone away.
What has changed is the financial calculus. A buyer stretching to £719,000 or thereabouts at current mortgage rates is paying significantly more each month than they would have been a year ago. Some buyers are recalibrating what they can afford. Others are choosing to wait, hoping that rates come down before they commit. That's rational behaviour, but it translates directly into those extended days-on-market figures and the modest SSTC conversion rate we're seeing across the area.
There's also a broader point worth making about the psychology of the market right now. When mortgage deals are being pulled and repriced at short notice, as happened repeatedly through the spring and early summer, buyers become skittish. Chains collapse. Offers are revised. Sellers who had mentally banked a sale find themselves back at square one. That creates a kind of ambient uncertainty that depresses activity even when conditions aren't objectively terrible.
What This Means If You're Selling in Tonbridge
A flat year-on-year price position and an average of 457 days on market doesn't mean property isn't selling in Tonbridge. It is. That 20% SSTC rate confirms it. But it does mean that the properties selling are the ones priced realistically and presented well. Buyers at this price point are sophisticated, often with advisers, and they're doing serious due diligence before committing to a purchase at current borrowing costs.
The national report is clear that there are hotspots even in this environment, places where strong local demand and limited supply keep transaction timescales short. Tonbridge has the ingredients to be that kind of market for the right property. The fundamentals, the connectivity, the lifestyle offer, are genuinely strong. But in the current climate, the premium attached to a well-priced, well-presented home has never been more important.
Looking Ahead
The trajectory of mortgage rates from here depends heavily on how the Iran situation develops and how financial markets respond. The average two-year fixed rate sitting at 5.61% in mid-August is meaningfully higher than it was six months ago, and while there's some distance from the April peak of close to 6%, it remains elevated by the standards buyers had grown accustomed to before this year.
If the geopolitical picture stabilises and inflationary pressures ease, markets expect rate-setters to have more room to move. That could shift sentiment relatively quickly, and when buyer confidence returns in a market with Tonbridge's underlying strengths, activity tends to pick up sharply. The question for sellers right now is how long they're prepared to wait, and whether a pricing adjustment in the short term might unlock a sale before conditions in the wider market resolve themselves.
The homes selling today in this market are the ones that have answered that question clearly.
