The 2026 median in DN21 is £160,000, from 171 registered sales; the mean, £227,200, sits well above it, the signature of a heavy top tail: a handful of expensive sales lifting the average.
For scale: the England and Wales median is £274,000, so DN21 trades 42% below the country as a whole.

In cash terms the typical DN21 home went from £40,500 in 1995 to £160,000 in 2026, roughly 4.0 times the price. Even after inflation that is a real rise of about 86%: homes here genuinely became dearer, not just more expensive on paper. Measured in today's money the market peaked in 2007; the current median sits about 20% below that. Someone who bought at the 2007 peak has not yet seen that price back in real terms.
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 2004 (+35.3% on the year before); the weakest, 1996 (−13.6%). Single-year swings like these are why the annualised table below matters more than any one year's headline.
| Period | Cash, per year | Real terms, per year |
|---|---|---|
| 1 years (since 2025) | −3.0% | −3.0% |
| 5 years (since 2021) | +2.0% | −2.3% |
| 10 years (since 2016) | +2.5% | −0.7% |
| 20 years (since 2006) | +1.7% | −1.0% |
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.
Recorded sales per year. The dip after 2008 is the financial crisis; the last bar is still filling in as recent sales get registered.
Monthly registrations. The sawtooth is seasonal; the register runs weeks behind completions at the right-hand edge.
DN21 recorded 613 sales in the last twelve months of data. Like most of England and Wales, turnover never fully recovered from 2008: the market here averaged 982 sales a year before the financial crisis and 700 a year over the last five. 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.
DN21 falls under West Lindsey, where the ONS puts the average private rent at £728 a month (May 2026 figures). A one-bed averages £531 a month here and a four-or-more-bed £1,129, so size does most of the work in setting the rent.
ONS Price Index of Private Rents, May 2026.
Set against the £160,000 median sold price, £728 a month is £8,736 a year, a gross yield of 5.5%: 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.
Nobody can tell you that, and this page will not pretend to. What the record shows: the median is up 10% over five years in cash but down 11% 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.
DN21 ranks 16 of 32 in the DN area on five-year growth. The gap between the top and bottom of this chart is the difference between buying well and buying badly in the same city.

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.
