TN15 prices by floor area

| 1996 | £93,000 | £196,133 | 404 |
| 1995 | £93,500 | £203,255 | 338 |
In cash terms the typical TN15 home went from £93,500 in 1995 to £500,000 in 2026, roughly 5 times the price. Inflation explains only part of it: in today's money the rise is still about 146%, a genuine increase in what a home here costs. Measured in today's money the market peaked in 2021; the current median sits about 17% below that. Someone who bought at the 2021 peak has not yet seen that price back in real terms.
Year-on-year change in the TN15 median
Each bar is the change on the year before, in cash. The zero line is the boundary between rising and falling.
The strongest year on record here is 1997 (+33.1% on the year before); the weakest, 1999 (−11.7%). Single-year swings like these are why the annualised table below matters more than any one year's headline.
Detached, semi, terraced, flat: four markets in one
A single median hides the split beneath it. Sales of detached houses dominate the record here, 43% of the typed total. A detached home currently trades at £787,500 against £225,000 for a flat, 3.5 times the price.

Growth per year, over one to twenty years
| Period | Cash, per year | Real terms, per year |
|---|---|---|
| 1 years (since 2025) | −4.8% | −7.0% |
| 5 years (since 2021) | +1.0% | −3.6% |
| 10 years (since 2016) | +1.9% | −1.5% |
| 20 years (since 2006) | +2.9% | +0.1% |
The table annualises median growth over each period, with the real column deflated by ONS CPIH. Smoothing hides the cycle (see the chart above for it), and none of this forecasts: it is the record.
Sales activity in TN15
The year-by-year sales count
Recorded sales per year. The dip after 2008 is the financial crisis; the last bar is still filling in as recent sales get registered.
The monthly pulse, last five years
Registrations by month. The repeating sawtooth is seasonality, and the right-hand edge always dips because the register lags completions.
TN15 recorded 265 sales in the last twelve months of data. Like most of England and Wales, turnover never fully recovered from 2008: the market here averaged 454 sales a year before the financial crisis and 283 a year over the last five. Watch the volume as closely as the price. Thin years make jumpy medians, where one street's sales can move the figure, and the newest year is always incomplete because registrations trail completions by weeks or months.
Rents around TN15
TN15 falls under Tonbridge and Malling, where the ONS puts the average private rent at £1,479 a month (May 2026 figures). Size sets most of the rent: one-beds average £1,025 a month here against £2,466 for four or more bedrooms.
Average monthly rent by size, Tonbridge and Malling
ONS Price Index of Private Rents, May 2026.
£1,479 a month is £17,748 a year, which against the £500,000 median sold price makes a gross yield of 3.5%. Gross means before letting costs, voids, maintenance and tax: treat it as a ceiling. The ONS publishes rents by local authority, so neighbouring districts under the same authority share these numbers.

Bedroom by bedroom: TN prices by size
Real sold prices by size across the TN area, straight from the Land Registry record. How much a size step costs is a local fact: the third-bedroom premium runs from about a quarter to nearly four fifths depending on the area, and national rules of thumb miss it.
