| 1995 | £81,500 | £177,168 | 99 |
In cash terms the typical OX39 home went from £81,500 in 1995 to £450,000 in 2026, roughly 6 times the price. Even after inflation that is a real rise of about 154%: homes here genuinely became dearer, not merely more expensive on paper. In inflation-adjusted terms the high-water mark was 2020. The market now sits about 20% below it, so a peak-time purchase has yet to recover its real value.
Year-on-year change in the OX39 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 2002 (+25.2% on the year before); the weakest, 2009 (−13.8%). Single-year swings like these are why the annualised table below matters more than any one year's headline.
Annualised returns
| Period | Cash, per year | Real terms, per year |
|---|---|---|
| 1 years (since 2025) | −2.2% | −4.5% |
| 5 years (since 2021) | +0.6% | −4.1% |
| 10 years (since 2016) | +2.5% | −0.8% |
| 20 years (since 2006) | +3.3% | +0.5% |
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, 36% of the typed total. In 2024, the last year both were recorded here, a detached home traded at £575,000 against £204,000 for a flat, 2.8 times the price.

Sales activity in OX39
Sales per year, counted
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.
OX39 recorded 103 sales in the last twelve months of data. Turnover has held fairly steady across the cycle: about 118 sales a year recently, against 131 a year before 2008. Volume matters as much as price: when few homes change hands, the median gets jumpy and a single street can move the figure. The most recent year is always still filling in, because sales appear in the Land Registry weeks or months after completion.
The shape of the OX39 market
Only 103 sales completed here in the last twelve months of data, which makes OX39 a thin market. Each figure rests on few transactions, so single streets can swing the median and the charts deserve a sceptical squint. OX39 sits 7 of 26 in its area's price order, well inside the expensive end.
Rents around OX39
The local authority for OX39 is South Oxfordshire, and its ONS average private rent currently stands at £1,381 a month (May 2026 figures). A one-bed averages £1,025 a month here and a four-or-more-bed £2,292, so size does most of the work in setting the rent.
Average monthly rent by size, South Oxfordshire
ONS Price Index of Private Rents, May 2026.
Set against the £450,000 median sold price, £1,381 a month is £16,572 a year, a gross yield of 3.7%: gross, before letting costs, voids, maintenance and tax, so a ceiling rather than a promise. Rents are published at local-authority level, so nearby districts in the same authority share these figures.

Moving up a bedroom in OX: the cost
Real sold prices by size across the OX 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.
