In cash terms the typical RM9 6 home went from £44,500 in 1995 to £360,000 in 2026, roughly 8 times the price. Adjusted for inflation it still comes to a real rise of roughly 272%, 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 25% below it, so a peak-time purchase has yet to recover its real value.
Year-on-year change in the RM9 6 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 2003 (+30.0% on the year before); the weakest, 2009 (−16.4%). Single-year swings like these are why the annualised table below matters more than any one year's headline.
What RM9 6 has returned, per year
| Period | Cash, per year | Real terms, per year |
|---|---|---|
| 1 years (since 2025) | −5.3% | −7.5% |
| 5 years (since 2021) | +2.1% | −2.6% |
| 10 years (since 2016) | +2.3% | −1.1% |
| 20 years (since 2006) | +4.1% | +1.2% |
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.
The turnover behind the prices
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.
RM9 6 recorded 44 sales in the last twelve months of data. Like most of England and Wales, turnover never fully recovered from 2008: the market here averaged 204 sales a year before the financial crisis and 77 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.
Rents around RM9 6
The local authority for RM9 6 is Barking and Dagenham, and its ONS average private rent currently stands at £1,690 a month (May 2026 figures). The spread runs from £1,371 a month for a typical one-bed to £2,507 at four-plus bedrooms, which is size doing most of the pricing.
Average monthly rent by size, Barking and Dagenham
ONS Price Index of Private Rents, May 2026.
Set against the £360,000 median sold price, £1,690 a month is £20,280 a year, a gross yield of 5.6%: 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.
Reading the RM9 6 market
Only 44 sales completed here in the last twelve months of data, which makes RM9 6 a thin market. Each figure rests on few transactions, so single streets can swing the median and the charts deserve a sceptical squint.

The price of an extra bedroom in RM
The Land Registry record, split by size: what each kind of home actually sold for across the RM area. 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.
