In cash terms the typical RM9 4 home went from £46,400 in 1995 to £385,000 in 2026, roughly 8 times the price. Inflation explains only part of it: in today's money the rise is still about 282%, a genuine increase in what a home here costs. In inflation-adjusted terms the high-water mark was 2022. The market now sits about 12% below it, so a peak-time purchase has yet to recover its real value.
Year-on-year change in the RM9 4 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 2014 (+31.4% on the year before); the weakest, 2009 (−18.2%). Single-year swings like these are why the annualised table below matters more than any one year's headline.
What RM9 4 has returned, per year
| Period | Cash, per year | Real terms, per year |
|---|---|---|
| 1 years (since 2025) | −1.3% | −3.6% |
| 5 years (since 2021) | +2.8% | −1.9% |
| 10 years (since 2016) | +3.2% | −0.2% |
| 20 years (since 2006) | +4.5% | +1.6% |
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.
The turnover behind the prices
The year-by-year sales count
Annual recorded sales. The post-2008 trough is the financial crisis; treat the final bar as provisional while registrations catch up.
RM9 4 recorded 27 sales in the last twelve months of data. Like most of England and Wales, turnover never fully recovered from 2008: the market here averaged 213 sales a year before the financial crisis and 67 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 RM9 4 market
Only 27 sales completed here in the last twelve months of data, which makes RM9 4 a thin market. Each figure rests on few transactions, so single streets can swing the median and the charts deserve a sceptical squint.
The rental side of RM9 4
The local authority for RM9 4 is Barking and Dagenham, and its ONS average private rent currently stands at £1,690 a month (May 2026 figures). Size sets most of the rent: one-beds average £1,371 a month here against £2,507 for four or more bedrooms.
Average monthly rent by size, Barking and Dagenham
ONS Price Index of Private Rents, May 2026.
£1,690 a month is £20,280 a year, which against the £385,000 median sold price makes a gross yield of 5.3%. Gross means before letting costs, voids, maintenance and tax: treat it as a ceiling. The ONS publishes rents by local authority, so neighbouring districts under the same authority share these numbers.

On the market in RM9 today

These cover the whole RM9 district, not just RM9 4: live asking prices are collected per district.
9% 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.

Moving up a bedroom in RM: the cost
What homes of each size actually sold for across the RM 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 | — | £450,000 | £575,000 (+28%) | £830,000 (+44%) | £1,150,000 (+39%) |
| Semi-detached | £365,000 | £425,000 (+16%) | £485,000 (+14%) | £635,000 (+31%) | £772,500 (+22%) |

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.
