    Property Price & Volume Trends

    Properties in TR21 command an average price of £549,000, placing it among the most expensive areas nationally. Over the past decade, prices have grown at 6.7% per year—significantly faster than the typical UK postcode district. However, transaction activity has slowed notably: only 14 sales occurred in the latest full year, compared with a 10-year average of 19 per year, reflecting the limited property turnover typical of island living.

    Rent & Yield Trends

    Average monthly rents stand at £1,004, close to the national midpoint. Rental growth has kept pace with the UK average at 3.9% per year over a decade. The flat yield on rental income currently stands at 4.4%, notably higher than the 10-year average of 3.5%, indicating an improving return for landlords despite the tight rental market that characterises island communities.

    Income & Affordability Trends

    Average household income of £39,739 sits slightly above the national median. The purchase affordability picture has deteriorated: the price-to-income ratio now stands at 14.8x, up significantly from 10.0x in 2016, reflecting the pace of price growth outpacing local wage growth. Rental affordability has improved slightly, with rent-to-income ratio declining from 29.3% in 2016 to 27.8% today.

    Resident Demographic Profile

    TR21 has a notably older population, with 27.7% aged 65 and over—well above the national average of 19.6%—and relatively few young adults: just 6.9% are aged 16–24, compared with 11.0% nationally. The housing tenure profile is distinctive: private renting is unusually high at 34.9% (against 21.7% nationally), while owner-occupation with a mortgage is low at 12.2% (against 27.0% nationally), likely reflecting the premium prices and lifestyle character of island property. Employment is skewed towards trades (16.0%) and caring professions (13.6%), reflecting the island's service-based economy.
