In cash terms the typical CM17 home went from £78,000 in 1995 to £400,000 in 2026, roughly 5 times the price. Adjusted for inflation it still comes to a real rise of roughly 136%, so homes here got dearer in substance, not only in cash. Measured in today's money the market peaked in 2021; the current median sits about 19% below that. Someone who bought at the 2021 peak has not yet seen that price back in real terms.
Year-on-year change in the CM17 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 2002 (+19.0% on the year before); the weakest, 2023 (−5.0%). 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) | −1.2% | −3.5% |
| 5 years (since 2021) | +0.5% | −4.1% |
| 10 years (since 2016) | +2.0% | −1.3% |
| 20 years (since 2006) | +3.5% | +0.7% |
The table annualises median growth over each period, with the real column deflated by ONS CPIH. Smoothing hides the cycle (see the chart above for it), and none of this forecasts: it is the record.
Detached, semi, terraced, flat: four markets in one
A single median hides the split beneath it. Sales of terraced homes dominate the record here, 39% of the typed total. A detached home currently trades at £532,500 against £235,000 for a flat, 2.3 times the price.

Transaction volumes
How many homes change hands
Annual recorded sales. The post-2008 trough is the financial crisis; treat the final bar as provisional while registrations catch up.
Month by month, five years back
Registrations by month. The repeating sawtooth is seasonality, and the right-hand edge always dips because the register lags completions.
Over the last twelve months of data, 346 sales completed in CM17. Like most of England and Wales, turnover never fully recovered from 2008: the market here averaged 697 sales a year before the financial crisis and 368 a year over the last five. Price without volume misleads: a median built on few sales jumps around, and one street can tilt it. Keep in mind too that the latest year is still filling in, since sales reach the register weeks or months after completion.
What tenants pay around CM17
CM17 falls under Harlow, where the ONS puts the average private rent at £1,517 a month (May 2026 figures). Size sets most of the rent: one-beds average £1,019 a month here against £2,196 for four or more bedrooms.
Average monthly rent by size, Harlow
ONS Price Index of Private Rents, May 2026.
Set against the £400,000 median sold price, £1,517 a month is £18,204 a year, a gross yield of 4.6%: 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.

The price of an extra bedroom in CM
The Land Registry record, split by size: what each kind of home actually sold for across the CM area. How much a size step costs is a local fact: the third-bedroom premium runs from about a quarter to nearly four fifths depending on the area, and national rules of thumb miss it.
