In cash terms the typical OX39 4 home went from £81,500 in 1995 to £450,000 in 2026, roughly 6 times the price. Inflation explains only part of it: in today's money the rise is still about 154%, a genuine increase in what a home here costs. The real-terms peak came in 2020, and today's median remains roughly 20% under it: a 2020 buyer is still waiting to get that price back in today's money.
Year-on-year change in the OX39 4 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.
Growth per year, over one to twenty years
| 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% |
Compound annual growth of the median sold price; the real column deflates by ONS CPIH. Annualised figures smooth the cycle (the chart above shows the cycle), and past growth is a record, not a forecast.
How many homes change hands in OX39 4
Sales per year, counted
Annual recorded sales. The post-2008 trough is the financial crisis; treat the final bar as provisional while registrations catch up.
Over the last twelve months of data, 45 sales completed in OX39 4. Turnover has held fairly steady across the cycle: about 118 sales a year recently, against 131 a year before 2008. 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 tenants pay around OX39 4
OX39 4 falls under South Oxfordshire, where the ONS puts the average private rent at £1,381 a month (May 2026 figures). Size sets most of the rent: one-beds average £1,025 a month here against £2,292 for four or more bedrooms.
Average monthly rent by size, South Oxfordshire
ONS Price Index of Private Rents, May 2026.
£1,381 a month is £16,572 a year, which against the £450,000 median sold price makes a gross yield of 3.7%. 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 kind of market OX39 4 is
Only 45 sales completed here in the last twelve months of data, which makes OX39 4 a thin market. Each figure rests on few transactions, so single streets can swing the median and the charts deserve a sceptical squint.

The price of an extra bedroom in OX
The Land Registry record, split by size: what each kind of home actually sold for across the OX area. 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.
