In cash terms the typical DA3 home went from £81,000 in 1995 to £502,500 in 2026, roughly 6 times the price. Even after inflation that is a real rise of about 185%: homes here genuinely became dearer, not merely more expensive on paper. The real-terms peak came in 2020, and today's median remains roughly 10% under it: a 2020 buyer is still waiting to get that price back in today's money.
Year-on-year change in the DA3 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 2014 (+39.6% on the year before); the weakest, 2009 (−12.2%). Single-year swings like these are why the annualised table below matters more than any one year's headline.
What DA3 has returned, per year
| Period | Cash, per year | Real terms, per year |
|---|---|---|
| 1 years (since 2025) | +6.7% | +4.2% |
| 5 years (since 2021) | +2.7% | −2.0% |
| 10 years (since 2016) | +3.4% | 0.0% |
| 20 years (since 2006) | +3.7% | +0.8% |
Each row is compound annual growth of the median; ONS CPIH supplies the real-terms deflator. Annualising irons out the cycle, which the chart above shows in full, and past growth records what happened rather than predicting anything.
Detached, semi, terraced, flat: four markets in one
A single median hides the split beneath it. Sales of detached houses dominate the record here, 37% of the typed total. A detached home currently trades at £687,500 against £263,200 for a flat, 2.6 times the price.

Sales activity in DA3
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
Sales as they reached the register each month. Expect the seasonal sawtooth, and discount the newest months while late entries land.
Over the last twelve months of data, 196 sales completed in DA3. Like most of England and Wales, turnover never fully recovered from 2008: the market here averaged 310 sales a year before the financial crisis and 212 a year over the last five. Price without volume misleads: a median built on few sales jumps around, and one street can tilt it. Keep in mind too that the latest year is still filling in, since sales reach the register weeks or months after completion.
What homes rent for around DA3
DA3 falls under Sevenoaks, where the ONS puts the average private rent at £1,790 a month (May 2026 figures). Size sets most of the rent: one-beds average £1,252 a month here against £2,926 for four or more bedrooms.
Average monthly rent by size, Sevenoaks
ONS Price Index of Private Rents, May 2026.
£1,790 a month is £21,480 a year, which against the £502,500 median sold price makes a gross yield of 4.3%. 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.

What another bedroom costs in DA
What homes of each size actually sold for across the DA area, from the Land Registry record. Size steps are fiercely local. A third bedroom adds a quarter to the price in some areas and close to four fifths in others, which is why no national rule of thumb survives contact with a real market.
| Type | 1 bed | 2 bed | 3 bed | 4 bed | 5 bed |
|---|---|---|---|---|---|
| Detached | — | £450,000 | £600,000 (+33%) | £800,000 (+33%) | £1,100,000 (+38%) |
| Semi-detached | £341,500 | £410,000 (+20%) | £480,000 (+17%) | £600,000 (+25%) | £712,500 (+19%) |

Medians of recorded sales over the last four years, by built form and bedroom count. Sold homes carry no advertised bedroom count, so sizes are estimated from their EPC records; a small number of homes will sit one size out. Sizes with too few homes to be meaningful are left blank.
