Rent & Yield Trends

Rent growth over the past decade has been flat at 2.5% annually, among the slowest in the country. The flat yield has improved recently to 4.8%, up from a 10-year average of 4.0%, suggesting a modestly strengthening rental return relative to capital values.
Income & Affordability Trends

The purchase affordability ratio has deteriorated: properties now cost 11.5 times average income, compared to 10.9 times in 2016. Rental affordability, by contrast, has improved markedly—the rent-to-income ratio has fallen from 35.8% to 33.6% over the same period, making rental housing slightly more accessible relative to local incomes.

The population skews towards middle age, with 35–49 year-olds representing 21.3% of residents—notably above the national average of 18.7%. Housing tenure is weighted toward ownership: 35.4% own outright and 32.7% with a mortgage, significantly exceeding national averages and reflecting the area's affluent, stable demographic. The employment mix is heavily tilted toward professional and managerial roles, with 28.7% in professional occupations and 18.8% in management—well above national norms of 20.5% and 13.4% respectively. Conversely, trades and elementary occupations are substantially underrepresented at 7.4% and 5.2%, compared to national figures of 10.5% and 10.2%.
