Sold house prices in NN1 (West Northamptonshire)
307 standard residential sales registered with HM Land Registry for completions from 1 August 2025 to 31 July 2026 (our data runs to 28 August 2026). The newest month, August 2026, is left out: HM Land Registry is still adding sales to it. Earlier recent months can still grow a little in later releases.
By property type
| Type | Sales | Median | Middle 50% | 95% interval of the median |
|---|---|---|---|---|
| Terraced | 194 | £225,000 | £196,000 – £266,875 | £217,000 – £232,000 |

Median = the middle sale price. Middle 50% = from the 25th to the 75th percentile. The 95% interval shows how far the median could move with a different set of sales; a wide interval means few or very varied sales. Types with fewer than 20 sales show no price.

Our median above is the middle actual sale in NN1 over 12 months — the two measure different things and can differ.

Area rent and gross yield
| Type | Area rent / month | Gross yield |
|---|---|---|
| Terraced | £1,063 | 5.7% |
| Flat / maisonette | £858 | 7.1% |
Area rent = ONS Price Index of Private Rents for the local authority of each sale (August 2026): the average rent of existing tenancies of that property type — an area baseline, not the rent a particular home would let for. Gross yield = area rent × 12 ÷ median price, before costs, tax and voids.
