The next year is likely to see continued steady price performance, given the one-year capital growth of 0.7% and the area’s ongoing appeal to affluent families. Liquidity should remain solid, as reflected by the current 46 days and consistent annual sales.
Rental yields are expected to hold around 4.4%, supported by the area’s professional and family demographic. However, affordability will remain a constraint for both buyers and renters, given the current ratios. Investors should expect gradual rather than explosive growth, with stability and tenant quality as the main selling points.
