In cash terms the typical SL9 home went from £190,000 in 1995 to £717,800 in 2026, roughly 3.8 times the price. Even after inflation that is a real rise of about 74%: homes here genuinely became dearer, not merely more expensive on paper. In inflation-adjusted terms the high-water mark was 2016. The market now sits about 32% below it, so a peak-time purchase has yet to recover its real value.
Year-on-year change in the SL9 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 1998 (+42.0% on the year before); the weakest, 2026 (−17.6%). Single-year swings like these are why the annualised table below matters more than any one year's headline.
What SL9 has returned, per year
| Period | Cash, per year | Real terms, per year |
|---|---|---|
| 1 years (since 2025) | −17.6% | −19.5% |
| 5 years (since 2021) | −2.1% | −6.7% |
| 10 years (since 2016) | −0.5% | −3.8% |
| 20 years (since 2006) | +1.9% | −0.9% |
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, 58% of the typed total. A detached home currently trades at £920,000 against £436,000 for a flat, 2.1 times the price.

Sales activity in SL9
How many homes change hands
Annual recorded sales. The post-2008 trough is the financial crisis; treat the final bar as provisional while registrations catch up.
Month by month, five years back
Monthly registrations. The sawtooth is seasonal; the register runs weeks behind completions at the right-hand edge.
SL9 recorded 233 sales in the last twelve months of data. Like most of England and Wales, turnover never fully recovered from 2008: the market here averaged 412 sales a year before the financial crisis and 245 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.
What tenants pay around SL9
SL9 falls under Buckinghamshire, where the ONS puts the average private rent at £1,477 a month (May 2026 figures). The spread runs from £1,036 a month for a typical one-bed to £2,364 at four-plus bedrooms, which is size doing most of the pricing.
Average monthly rent by size, Buckinghamshire
ONS Price Index of Private Rents, May 2026.
£1,477 a month is £17,724 a year, which against the £717,800 median sold price makes a gross yield of 2.5%. 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.
The shape of the SL9 market
Expect volatility in the annual figures: swings past ten per cent show up repeatedly above, and they usually reflect the mix of homes sold in a given year rather than genuine repricing. SL9 is currently the dearest district of its postcode area by median price.

Bedroom by bedroom: SL prices by size
Real sold prices by size across the SL 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.
