CM20 1 is a postcode sector: one group of streets inside CM20 (Harlow). This is as local as the public record gets, but sector medians move on fewer sales than a district's, so expect the lines to be lumpier.

In cash terms the typical CM20 1 home went from £53,000 in 1995 to £257,500 in 2026, roughly 5 times the price. Adjusted for inflation it still comes to a real rise of roughly 123%, so homes here got dearer in substance, not only in cash. Measured in today's money the market peaked in 2022; the current median sits about 32% below that. Someone who bought at the 2022 peak has not yet seen that price back in real terms.
Year-on-year change in the CM20 1 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 (+34.2% on the year before); the weakest, 2023 (−16.5%). Single-year swings like these are why the annualised table below matters more than any one year's headline.
The long view: annualised growth
| Period | Cash, per year | Real terms, per year |
|---|---|---|
| 1 years (since 2025) | −13.3% | −15.3% |
| 5 years (since 2021) | −1.9% | −6.4% |
| 10 years (since 2016) | +0.8% | −2.5% |
| 20 years (since 2006) | +3.1% | +0.3% |
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.
Sales activity in CM20 1
Sales per year, counted
Recorded sales per year. The dip after 2008 is the financial crisis; the last bar is still filling in as recent sales get registered.
CM20 1 recorded 16 sales in the last twelve months of data. Like most of England and Wales, turnover never fully recovered from 2008: the market here averaged 116 sales a year before the financial crisis and 64 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.
Reading the CM20 1 market
Only 16 sales completed here in the last twelve months of data, which makes CM20 1 a thin market. Each figure rests on few transactions, so single streets can swing the median and the charts deserve a sceptical squint. The record here is jumpy: year-on-year moves of ten per cent or more are common in the chart above, mostly a function of which homes happened to sell rather than the market lurching. Against the CM20 district median, CM20 1 sits 21% lower, marking it as a cheaper pocket of the district.
Rents around CM20 1
CM20 1 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 £257,500 median sold price, £1,517 a month is £18,204 a year, a gross yield of 7.1%: 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.

What another bedroom costs 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.
| Type | 1 bed | 2 bed | 3 bed | 4 bed | 5 bed |
|---|---|---|---|---|---|
| Detached | — | £417,500 | £550,000 (+32%) | £785,000 (+43%) | £1,137,500 (+45%) |

Four years of recorded sales, split by built form and bedroom count. The register does not state bedrooms, so sizes come from each home's EPC record and a few homes will land one size out. Sizes with too few homes to be meaningful are left blank.
