How King Street, Northampton prices moved
The chart tracks the median King Street, Northampton house price for every year with a recorded sale, from 1995 to 2024. The dashed line restates each year in 2026 money, so the two lines separate exactly as much as inflation has eroded the cash figure.
| Decade | Years with sales | Median paid | In today's money |
|---|---|---|---|
| 1990s | 3 | £44,500 | £98,811 |
| 2000s | 5 | £102,250 | £186,269 |
| 2010s | 6 | £165,250 | £233,003 |
| 2020s | 2 | £226,250 | £231,168 |
The highest yearly median on record for King Street, Northampton is £250,000 in 2024; the lowest is £39,500 in 1995. Across the full 30-year record the cash median has moved from £39,500 to £250,000.
In 2026 money that first median is worth £87,709, so the real change over the whole record is +199.9% — about +3.86% a year after inflation. Cash growth and real growth are not the same story, and the gap is the part most price reports leave out.
Over the last decade alone the difference is stark: +125.2% in cash against +58.7% once inflation is removed. A buyer who sold at the end of that decade would have needed the real figure, not the headline one, to know whether they had actually gained.

The most recent sales
Every row is a completed sale as lodged with HM Land Registry. The right-hand column restates the price in 2026 money, which is the only fair way to compare a sale from the 1990s with one from last year.

Homes that sold twice
These addresses appear in the register more than once, so the same bricks are being priced twice. That makes them the strongest evidence of what actually happened to King Street, Northampton values — no mix of property types can flatter the number.

What sells here
The mix of property types explains a large part of any area's median. King Street, Northampton is dominated by the type at the top of this table, so its overall median leans that way.
| Property type | Sales | Share | Median paid | Range |
|---|---|---|---|---|
| Terraced | 108 | 71.5% | £119,500 | £25,000 – £287,500 |
| Semi-detached | 30 | 19.9% | £152,000 | £48,500 – £385,000 |
| Detached | 12 | 7.9% | £169,000 | £39,000 – £540,000 |
| Flat or maisonette | 1 | 0.7% | £120,000 | £120,000 – £120,000 |
Section 06
Ownership and new build in King Street, Northampton
3 of the sales on record are leasehold and 148 freehold — 2.0% of the market. Tenure is not a detail: a leasehold flat and a freehold house are different assets, and mixing them into one median hides the difference.
The median leasehold sale is £120,000 and the median freehold sale £130,000 — a gap of +8.3%. Most of that gap is property type rather than tenure itself: leasehold here is largely flats, freehold largely houses.
| Category | Sales | Share | Median paid |
|---|---|---|---|
| Leasehold | 3 | 2.0% | £120,000 |
| Freehold | 148 | 98.0% | £130,000 |
A further 5 transfers for this area are on the register but are left out of every figure above. HM Land Registry marks them as additional price paid entries: repossessions, buy-to-let portfolio moves, transfers between companies or family, and sales at a discount such as right to buy. They are real records but they are not open-market prices, and including them would drag the median somewhere no buyer ever paid.

Living in King Street, Northampton
Every certificate carries an energy efficiency band as well as a floor area. Across Harborough, 50.4% of 45,538 certificates sit in bands A to C, and 4.8% in F or G — the bands that cost the most to heat and are hardest to mortgage.
| Energy band | Certificates | Share |
|---|---|---|
| A | 349 | 0.8% |
| B | 9,947 | 21.8% |
| C | 12,670 | 27.8% |

The Office for National Statistics puts the mean private rent in Harborough at £962 a month as of Jun 2026 — £706 for a one-bedroom home and £1,104 for three bedrooms.
Against the median sale of £130,000 here, that rent is a gross yield of 8.88% a year. It is a measured figure rather than an assumption: a real local rent over a real local price, before any cost of ownership.
Police forces publish every recorded street-level crime. Within a mile of the centre of NN6, 2 crimes were recorded in Jun 2026: 1 violent, 0 burglary, 0 vehicle-related and 1 anti-social behaviour. The median postcode district in this archive recorded 167 in the same month, so this one is 83.5 times quieter.
Against the 97,625 residents the 2021 census counted in Harborough, that is 0.02 recorded crimes per thousand people in the month. The count covers a mile around the district centre while the population covers the whole council, so read the rate as an order of magnitude rather than a precise figure.
A count is not a rate. A district with shops and a station records more crime than a residential one of the same size, because more people pass through it. Read this next to the median, not on its own.

The neighbourhood around King Street, Northampton
The 2021 census counted 97,625 residents in Harborough across 40,414 households. 77.8% of those households own their home and 22.2% rent — a split the sold record cannot show, because only owners appear in it.
21 state and independent schools have a NN6 postcode: 20 primary, 1 secondary. Catchment areas do not follow postcodes, so treat this as what is nearby rather than what a child would be offered.

How King Street, Northampton compares
The median across the whole archive is £157,500. King Street, Northampton sits below that national figure — -17.5%.
Within Northampton the street ranks 2201 of 3280 by median price, and its median is below the town figure of £146,001 (-11.0%).
No EPC floor areas could be matched to these sales, so no price per square metre is published here. An estimate would be a guess, and the archive does not publish guesses.
The full range on record runs from £25,000 to £540,000. Extremes usually mean something unusual — a plot sold without a house on it, a transfer between family members, or a very large property — so the median is the number to trust.
King Street, Northampton sits in Harborough, in the East Midlands.
The Office for National Statistics puts the median home in Harborough at 10.4 times median local earnings of £31,890 a year, measured to Sep 2025. Across England and Wales the same ratio is 7.6. That number, not the price alone, is what decides whether a place is within reach of the people who work in it.

Quick answers
Common questions about this data
What is the average house price in King Street, Northampton?
The median price paid in King Street, Northampton across every sale on the register is £130,000. The median is used rather than the mean because a handful of very large sales would otherwise drag the average away from what a typical buyer paid.
How many homes have sold in King Street, Northampton?
151 sales are on record for King Street, Northampton, the most recent completing on 24 Oct 2025. Every one is a completed transfer lodged with HM Land Registry, not an asking price or an estimate.
Have King Street, Northampton house prices actually risen?
In cash, the median rose +125.2% between 2012 and 2024. In 2026 money — that is, after inflation — the change is +58.7%. Both numbers are true; only the second one tells you whether buying here preserved value.
When were King Street, Northampton house prices at their highest?
The highest yearly median on record is £250,000, set in 2024. That is the cash figure; measured in 2026 money the peak may fall in a different year, because inflation reshapes the series.
What is the price per square metre in King Street, Northampton?
No EPC floor areas could be matched to these sales, so no price per square metre is published for this area. Nothing is estimated to fill the gap.
How current is this data?
The latest sale shown here completed on 24 Oct 2025. HM Land Registry publishes Price Paid Data monthly and a sale can take a month or two to appear after completion, so the most recent weeks are always incomplete.
