Gilston market report CM20 3, Harlow
The standing CM20 3 (Gilston) property market report, rebuilt from the full public record every month. Underneath every chart here sit 3,687 registered sales in CM20 3 (Harlow) since 1995, the HM Land Registry record of what buyers really paid, with ONS figures covering rents. Nothing is a valuation, an estimate or an asking price.
Sales recorded to 2026; rents are ONS figures for May 2026. The page rebuilds with each monthly release.
In short: 31 registered 2026 sales put the CM20 3 (Harlow) median at £338,000, up 15% on five years earlier, with a mean of £329,900, and by floor area homes here have averaged about £3,870 per square metre over the last five years. Everything rests on 3,687 completed HM Land Registry sales since 1995, refreshed monthly; valuations and asking prices play no part.
CM20 3 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 3 home went from £55,000 in 1995 to £338,000 in 2026, roughly 6 times the price. Adjusted for inflation it still comes to a real rise of roughly 183%, so homes here got dearer in substance, not only in cash. In inflation-adjusted terms the high-water mark was 2022. The market now sits about 11% below it, so a peak-time purchase has yet to recover its real value.
Year-on-year change in the CM20 3 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 (+25.6% on the year before); the weakest, 2009 (−7.2%). 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) | +4.0% | +1.6% |
| 5 years (since 2021) | +2.8% | −2.0% |
| 10 years (since 2016) | +3.3% | −0.1% |
| 20 years (since 2006) | +4.3% | +1.4% |
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.
Transaction volumes
How many homes change hands
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 register shows 31 CM20 3 sales across the most recent twelve months of data. Like most of England and Wales, turnover never fully recovered from 2008: the market here averaged 162 sales a year before the financial crisis and 88 a year over the last five. Watch the volume as closely as the price. Thin years make jumpy medians, where one street's sales can move the figure, and the newest year is always incomplete because registrations trail completions by weeks or months.
How CM20 3 trades
This is a thin market: 31 sales in the last twelve months of data. With that few transactions, one street selling well (or one block of cheap transfers) can move the median, so read the year lines as a range rather than a verdict.
What homes rent for around CM20 3
For renting purposes CM20 3 sits in Harlow. The ONS average private rent there is £1,517 a month (May 2026). 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 £338,000 median sold price, £1,517 a month is £18,204 a year, a gross yield of 5.4%: 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.

Is CM20 3 (Gilston) a good place to buy a house?

CM20's current homes for sale
This is what you could actually buy today: 242 homes currently on the market from 4 agents publishing to HomesIndex.
These cover the whole CM20 district, not just CM20 3: live asking prices are collected per district.
20% of what is on the market here is asking below what comparable homes actually sold for. Each listing is compared with recent recorded sales of similar homes nearby.
The "under comparable sales" label measures each asking price against real nearby sales of similar homes: an opening position for a conversation rather than a valuation. The home itself still needs looking at.

These asking prices come live from estate agents publishing feeds to HomesIndex, refreshed each Monday and Thursday. They are a sample of the market rather than its entirety, and an asking price is not a sale price.
Moving up a bedroom in CM: the cost
What homes of each size actually sold for across the CM area, from the Land Registry record. Size steps are fiercely local. A third bedroom adds a quarter to the price in some areas and close to four fifths in others, which is why no national rule of thumb survives contact with a real market.
| Type | 1 bed | 2 bed | 3 bed | 4 bed | 5 bed |
|---|---|---|---|---|---|
| Detached | — | £417,500 | £550,000 (+32%) | £785,000 (+43%) | £1,137,500 (+45%) |
| Semi-detached | £325,000 | £370,000 (+14%) | £447,500 (+21%) | £575,000 (+28%) | £780,000 (+36%) |
| Terraced | £292,000 | £335,000 (+15%) | £380,000 (+13%) | £492,500 (+30%) | £700,000 (+42%) |

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. Blank cells mean too few homes for the figure to mean anything.
