In cash terms the typical CA20 home went from £48,500 in 1995 to £195,000 in 2026, roughly 4 times the price. Even after inflation that is a real rise of about 89%: homes here genuinely became dearer, not just more expensive on paper. Measured in today's money the market peaked in 2005; the current median sits about 21% below that. Someone who bought at the 2005 peak has not yet seen that price back in real terms.
Year-on-year change in the CA20 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 2004 (+42.7% on the year before); the weakest, 2001 (−17.5%). Single-year swings like these are why the annualised table below matters more than any one year's headline.

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
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 last five years, month by month
Monthly registrations. The sawtooth is seasonal; the register runs weeks behind completions at the right-hand edge.
CA20 recorded 76 sales in the last twelve months of data. Like most of England and Wales, turnover never fully recovered from 2008: the market here averaged 74 sales a year before the financial crisis and 57 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.
What homes rent for around CA20
CA20 falls under Cumberland, where the ONS puts the average private rent at £666 a month (May 2026 figures). A one-bed averages £496 a month here and a four-or-more-bed £1,071, so size does most of the work in setting the rent.
Average monthly rent by size, Cumberland
ONS Price Index of Private Rents, May 2026.
Set against the £195,000 median sold price, £666 a month is £7,992 a year, a gross yield of 4.1%: 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 CA20 prices rise from here?
Nobody can tell you that, and this page will not pretend to. What the record shows: the median is up 5% over five years in cash but down 15% 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
CA20 ranks 15 of 28 in the CA 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.
