SN13 9 is a postcode sector: one group of streets inside SN13 (Corsham). This is as local as the public record gets, but sector medians move on fewer sales than a district's, so expect the lines to be lumpier.

In cash terms the typical SN13 9 home went from £60,900 in 1995 to £386,000 in 2026, roughly 6 times the price. Inflation explains only part of it: in today's money the rise is still about 192%, a genuine increase in what a home here costs. Measured in today's money the market peaked in 2021; the current median sits about 14% 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 SN13 9 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 2003 (+22.8% on the year before); the weakest, 2009 (−15.9%). 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) | +2.9% | +0.5% |
| 5 years (since 2021) | +1.8% | −2.9% |
| 10 years (since 2016) | +2.5% | −0.9% |
| 20 years (since 2006) | +2.9% | +0.1% |
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.
Transaction volumes
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.
SN13 9 recorded 54 sales in the last twelve months of data. Like most of England and Wales, turnover never fully recovered from 2008: the market here averaged 218 sales a year before the financial crisis and 145 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 SN13 9
The local authority for SN13 9 is Wiltshire, and its ONS average private rent currently stands at £1,064 a month (May 2026 figures). Size sets most of the rent: one-beds average £736 a month here against £1,711 for four or more bedrooms.
Average monthly rent by size, Wiltshire
ONS Price Index of Private Rents, May 2026.
£1,064 a month is £12,768 a year, which against the £386,000 median sold price makes a gross yield of 3.3%. 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.
Reading the SN13 9 market
This is a thin market: 54 sales in the last twelve months of data. With that few transactions, one street selling well (or one block of cheap transfers) can move the median, so read the year lines as a range rather than a verdict.

Are property prices falling in SN13 9 (Box)?
Is SN13 9 (Box) a good place to buy a house?
Are SN13 9 prices heading up or down?
That question has no honest answer, only evidence. The evidence: the median is up 10% over five years in cash but down 14% after inflation. Weigh the volume chart alongside the price one before deciding anything, and bear in mind every figure is a completed sale that reached the register weeks after completion.
SN13's current homes for sale
The live side of the market holds 30 homes at the moment, listed by 5 agents publishing to HomesIndex.
These cover the whole SN13 district, not just SN13 9: live asking prices are collected per district.
17% of current listings sit under the prices comparable homes actually fetched. The comparison behind each listing uses recent recorded sales of similar homes close by.
The "under comparable sales" label measures each asking price against real nearby sales of similar homes: an opening position for a conversation rather than a valuation. The home itself still needs looking at.

What another bedroom costs in SN
Real sold prices by size across the SN 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.

Built from the last four years of recorded sales by form and bedroom count. Bedroom counts are estimated from EPC records (the register carries none), so expect a small number of homes one size adrift. Blank cells mean too few homes for the figure to mean anything.
