A house in Castle Green costs around £385,000, and the house in question is nearly always a terrace. Terraces make up most of what sells. Semis cost more and rarely come up. Flats, at around £225,000, are the cheaper way in. The estate was built to one pattern, and it still sells like one.
The Land Registry recorded 168 sales in the year to May 2026, at a median price of about £385,000. Terraces made up 135 of those sales at a median of about £387,000. The 13 semi-detached houses went for about £455,000 and the 19 flats for about £225,000. Becontree was built between 1919 and 1935 as public housing for returning soldiers and families crowded out of central London. The terraces put up for them now change hands at £387,000, which is not a sum anyone in 1919 had in mind.
The house price index for the area showed average prices down 0.2% over the year to May 2026, a change too small to mean much. Flats did worse, down 3.4% over the same twelve months. That is decent news for a first-time buyer pricing up a flat. It is less welcome for anyone who bought one in the last few years planning to sell up into a terrace.
Band C is the most common council tax band in Castle Green, and only about 16% of homes fall in bands A or B. The Band D bill in Barking and Dagenham is about £2,199 a year. Most houses here are close to identical, so the council tax bills are too.
For renters, the typical private rent across the Barking and Dagenham area was about £1,690 a month in April 2026, up about 6% on a year earlier. That figure is an average for the whole borough from the Office for National Statistics' rent index, and it doesn't come from advertised listings in Castle Green. By size, one-bedroom homes averaged about £1,370 a month, two-bedroom homes about £1,710, three-bedroom homes about £1,880, and homes with four or more bedrooms about £2,510. Studio and room rents aren't published for the area.
Household income is modelled at around £64,000 a year for the financial year to March 2023, averaged across the area. That figure is gross, before tax, and a mortgage lender works from what is left after tax. Against a median sale price of £385,000, a terrace is within reach for a two-income household and a real stretch for one earner.
Price per square metre comes out at a median of about £5,190, based on a typical floor area of about 73 square metres. That covers about 94% of the year's sales, the ones that could be matched to an energy certificate's floor area. The terraces were built from a small set of standard plans, so the floor area on a house's energy certificate is the quickest way to compare one asking price with another.
The 2021 Census counted about 10% of homes with one bedroom, 42% with two, 42% with three and 7% with four or more. The market is almost entirely two- and three-bedroom homes. A family that needs a fourth bedroom will have a long wait, and probably a loft conversion at the end of it.
Castle Green costs a little more than middling for what it is, but it is a reasonable deal for a family: a London terrace with a garden at a price that has held steady. Buyers looking for something bigger than three bedrooms will struggle to find it here.
