Property Price & Volume Trends
The latest average property price in SO23 is £552,000, placing it among the most expensive nationally. However, over the past decade, prices have grown at just 2.3% per year — well below the national average, reflecting more modest appreciation than the wider market.

Rent & Yield Trends
Average monthly rent in the broader SO postcode area is £1,254, sitting just above the national median. Rental growth has been steady at 3.8% per year over the past decade, in line with national rates. The flat yield stands at 5.9%, a notable improvement on the 10-year average of 4.8%, reflecting better income relative to capital values.
Income & Affordability Trends
Average net household income is £43,709, above the national average. Despite this, affordability for buyers has worsened materially: the price-to-income ratio now stands at 13.7x, up from 11.8x in 2016, signalling a shift towards higher relative purchase costs. Rental affordability has also edged backwards, with rent consuming 29.9% of income compared to 28.4% a decade ago.
Resident Demographic Profile
The population is notably younger than the national average, with over a quarter aged 16–24 — significantly above the typical 11%. Housing tenure is markedly different: outright ownership is below average at 26%, whilst social rented housing is unusually prevalent at 28%, compared to the national 16.5%. The employment profile is heavily skewed towards professionals, who make up nearly 30% of the workforce against a national average of 20.5%, whilst trades are notably underrepresented at 6.9%.
