In cash terms the typical CM20 home went from £53,500 in 1995 to £325,000 in 2026, roughly 6 times the price. Even after inflation that is a real rise of about 179%: homes here genuinely became dearer, not merely more expensive on paper. In inflation-adjusted terms the high-water mark was 2021. The market now sits about 13% below it, so a peak-time purchase has yet to recover its real value.
Year-on-year change in the CM20 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 (+28.0% on the year before); the weakest, 2009 (−9.7%). Single-year swings like these are why the annualised table below matters more than any one year's headline.
Detached, semi, terraced, flat: four markets in one
A single median hides the split beneath it. Sales of terraced homes dominate the record here, 45% of the typed total. A detached home currently trades at £636,000 against £214,000 for a flat, 3.0 times the price.

What CM20 has returned, per year
| Period | Cash, per year | Real terms, per year |
|---|---|---|
| 1 years (since 2025) | +3.2% | +0.8% |
| 5 years (since 2021) | +1.9% | −2.8% |
| 10 years (since 2016) | +2.3% | −1.0% |
| 20 years (since 2006) | +3.7% | +0.9% |
Each row is compound annual growth of the median; ONS CPIH supplies the real-terms deflator. Annualising irons out the cycle, which the chart above shows in full, and past growth records what happened rather than predicting anything.
Transaction volumes
Sales per year, counted
Each bar is a year's recorded sales. 2008's dip is the financial crisis, and the newest bar always grows for a while as late registrations arrive.
The monthly pulse, last five years
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, 191 sales completed in CM20. Like most of England and Wales, turnover never fully recovered from 2008: the market here averaged 376 sales a year before the financial crisis and 267 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 CM20
For renting purposes CM20 sits in Harlow. The ONS average private rent there is £1,517 a month (May 2026). The spread runs from £1,019 a month for a typical one-bed to £2,196 at four-plus bedrooms, which is size doing most of the pricing.

ONS Price Index of Private Rents, May 2026.
Against the £325,000 median purchase price, a rent of £1,517 a month (£18,204 a year) works out at a 5.6% gross yield, a ceiling figure that ignores letting costs, voids, maintenance and tax. Because rents are local-authority statistics, districts sharing the authority share the figure.

The price of an extra bedroom in CM
What homes of each size actually sold for across the CM area, from the Land Registry record. The jump between sizes is local: in some areas a third bedroom adds a quarter to the price, in others nearly four fifths, so a national rule of thumb will mislead you here.

|---|---|---|---|---|---|
| Detached | — | £417,500 | £550,000 (+32%) | £785,000 (+43%) | £1,137,500 (+45%) |
