NN4 9 is a postcode sector: one group of streets inside NN4 (Northampton). 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 NN4 9 home went from £50,500 in 1995 to £312,500 in 2026, roughly 6 times the price. Inflation explains only part of it: in today's money the rise is still about 185%, a genuine increase in what a home here costs. The real-terms peak came in 2018, and today's median remains roughly 19% under it: a 2018 buyer is still waiting to get that price back in today's money.
Year-on-year change in the NN4 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 (+35.6% on the year before); the weakest, 2008 (−14.7%). Single-year swings like these are why the annualised table below matters more than any one year's headline.
What NN4 9 has returned, per year
| Period | Cash, per year | Real terms, per year |
|---|---|---|
| 1 years (since 2025) | −1.8% | −4.1% |
| 5 years (since 2021) | +1.2% | −3.5% |
| 10 years (since 2016) | +2.5% | −0.9% |
| 20 years (since 2006) | +2.8% | +0.1% |
The table annualises median growth over each period, with the real column deflated by ONS CPIH. Smoothing hides the cycle (see the chart above for it), and none of this forecasts: it is the record.
Sales activity in NN4 9
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.
Over the last twelve months of data, 46 sales completed in NN4 9. Like most of England and Wales, turnover never fully recovered from 2008: the market here averaged 192 sales a year before the financial crisis and 108 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 tenants pay around NN4 9
For renting purposes NN4 9 sits in West Northamptonshire. The ONS average private rent there is £1,072 a month (May 2026). The spread runs from £744 a month for a typical one-bed to £1,665 at four-plus bedrooms, which is size doing most of the pricing.
Average monthly rent by size, West Northamptonshire
ONS Price Index of Private Rents, May 2026.
Set against the £312,500 median sold price, £1,072 a month is £12,864 a year, a gross yield of 4.1%: 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.
Reading the NN4 9 market
Only 46 sales completed here in the last twelve months of data, which makes NN4 9 a thin market. Each figure rests on few transactions, so single streets can swing the median and the charts deserve a sceptical squint.

Bedroom by bedroom: NN prices by size
The Land Registry record, split by size: what each kind of home actually sold for across the NN area. 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.

| Detached | — | £291,500 | £385,000 (+32%) | £569,996 (+48%) | £752,854 (+32%) |

Four years of recorded sales, split by built form and bedroom count. The register does not state bedrooms, so sizes come from each home's EPC record and a few homes will land one size out. Sizes with too few homes to be meaningful are left blank.
