House prices per square metre in NN4

In cash terms the typical NN4 home went from £53,000 in 1995 to £300,000 in 2026, roughly 6 times the price. Inflation explains only part of it: in today's money the rise is still about 160%, a genuine increase in what a home here costs. The real-terms peak came in 2022, and today's median remains roughly 17% under it: a 2022 buyer is still waiting to get that price back in today's money.
Year-on-year change in the NN4 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 (+22.0% on the year before); the weakest, 2026 (−3.2%). 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) | −3.2% | −5.5% |
| 5 years (since 2021) | +1.4% | −3.3% |
| 10 years (since 2016) | +2.7% | −0.7% |
| 20 years (since 2006) | +3.1% | +0.3% |
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.
Detached, semi, terraced, flat: four markets in one
A single median hides the split beneath it. Sales of detached houses dominate the record here, 44% of the typed total. A detached home currently trades at £395,000 against £165,000 for a flat, 2.4 times the price.

Sales activity in NN4
How many homes change hands
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
Monthly registrations. The sawtooth is seasonal; the register runs weeks behind completions at the right-hand edge.
NN4 recorded 607 sales in the last twelve months of data. Like most of England and Wales, turnover never fully recovered from 2008: the market here averaged 1,824 sales a year before the financial crisis and 697 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.
How NN4 trades
Among the 19 measurable districts of its area, NN4 ranks 5 by median price: firmly in the dearer tier.
The rental side of NN4
The local authority for NN4 is West Northamptonshire, and its ONS average private rent currently stands at £1,072 a month (May 2026 figures). 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.
£1,072 a month is £12,864 a year, which against the £300,000 median sold price makes a gross yield of 4.3%. 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.

Moving up a bedroom in NN: the cost
What homes of each size actually sold for across the NN area, 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.

|---|---|---|---|---|---|
| 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. Blank cells mean too few homes for the figure to mean anything.
