NN17 local market report Corby

Every figure on this page comes from the public record: 16,928 sales registered with HM Land Registry in NN17 (Corby) since 1995, each one a completed purchase at a real price, plus current rental figures from the ONS. Nothing here is a valuation, an estimate or an asking price.

Sales data to May 2026. Rents: ONS, May 2026. Regenerated with every monthly data refresh.

NN17 is the postcode district covering Corby, Weldon, Gretton in Corby. Districts are a practical way to slice a market: small enough to mean something locally, big enough to have a steady flow of sales to measure.

What a home in NN17 sells for

The 2026 median in NN17 is £233,500, from 114 registered sales; the mean, £252,100, sits modestly above it, the usual shape of a market with an expensive tail.

For scale: the England and Wales median is £274,000, so NN17 trades 15% below the country as a whole.

In cash terms the typical NN17 home went from £33,500 in 1995 to £233,500 in 2026, roughly 7 times the price. Even after inflation that is a real rise of about 228%: homes here genuinely became dearer, not just more expensive on paper. Measured in today's money the market peaked in 2022; the current median sits about 13% below that. Someone who bought at the 2022 peak has not yet seen that price back in real terms.

The strongest year on record here is 2002 (+25.5% on the year before); the weakest, 2009 (−5.2%). Single-year swings like these are why the annualised table below matters more than any one year's headline.

Annualised returns

Period	Cash, per year	Real terms, per year
1 years (since 2025)	−1.7%	−1.7%
5 years (since 2021)	+1.7%	−2.6%
10 years (since 2016)	+4.9%	+1.7%
20 years (since 2006)	+4.4%	+1.7%

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.

Transaction volumes

NN17 recorded 469 sales in the last twelve months of data. Turnover has held fairly steady across the cycle: about 598 sales a year recently, against 549 a year before 2008. Volume matters as much as price: when few homes change hands, the median gets jumpy and a single street can move the figure. The most recent year is always still filling in, because sales appear in the Land Registry weeks or months after completion.

What homes rent for around NN17

NN17 falls under North Northamptonshire, where the ONS puts the average private rent at £984 a month (May 2026 figures). A one-bed averages £677 a month here and a four-or-more-bed £1,518, so size does most of the work in setting the rent.

Set against the £233,500 median sold price, £984 a month is £11,808 a year, a gross yield of 5.1%: 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.

Will NN17 prices rise from here?

Nobody can tell you that, and this page will not pretend to. What the record shows: the median is up 9% over five years in cash but down 12% after inflation. If you are weighing a purchase, read the volume chart alongside the price one, and remember that every figure here is a completed sale, lagged by the weeks it takes the Land Registry to register it.

Ladders and snakes: five-year risers and fallers

How this page is made: the statistics are computed from HM Land Registry Price Paid Data (Crown copyright, OGL v3.0), geocoded to address level; inflation adjustment uses the ONS CPIH index; rents are the ONS Price Index of Private Rents at local-authority level. Medians of recorded sales, not valuations. Nothing on this page is financial advice.
