    Property Price & Volume Trends

    The average property price of £761,000 places CM4 among the most expensive nationally. Annual price growth over the past decade has averaged 3.0%, which is below the national rate of appreciation. Transaction activity has remained stable, with 166 sales in the latest year very close to its 10-year average of 162 per annum.

    Rent & Yield Trends

    Average monthly rent in the broader CM postcode area stands at £1,413, positioning it above the national midpoint. Rental growth over ten years has averaged 4.2% annually, matching the national trend. The flat yield has strengthened to 5.6% in the latest year from a 10-year average of 4.6%, reflecting an improving picture for rental investors.

    Income & Affordability Trends

    Household incomes in CM4 are notably strong at £49,079, well above the national average. However, affordability remains stretched: the price-to-income ratio of 17.2x has deteriorated from 16.1x in 2016, making property ownership increasingly expensive relative to earnings. Rental affordability has also worsened, with tenants now spending 31.5% of income on rent compared to 27.6% in 2016.

    Resident Demographic Profile

    CM4 skews significantly older and more established than the nation as a whole. Those aged 50 and over account for nearly half the population (48.2% versus 39.4% nationally), while children under 15 and young adults aged 16–24 are notably underrepresented. The tenure profile reflects this maturity: 45% own their home outright—well above the national 33.7%—whilst private renting is half the national share at 12.6%. The employment mix is weighted towards managers (21.6% versus 13.4% nationally) and professionals, with fewer workers in elementary roles, underscoring the area's affluent, established character.
