The outlook for Tonbridge is mildly positive, with steady annualised growth over three years at 2.7% and a resilient local market. The high proportion of family households should underpin stable demand for larger properties, especially three-bedroom houses.
Although capital growth has changed by -1.7% over the last year, the longer-term trend remains upward. Rental yields are likely to stay competitive, and the balance between asking prices and achieved values suggests buyers can still find value. Investors should expect continued stability, with moderate growth and ongoing demand driven by the area’s demographic strengths.
