Looking ahead, Thornbury’s housing market is likely to remain underpinned by its high proportion of owner-occupiers and stable population structure. The area’s affordability, as reflected by a 5.0 price-to-income ratio, should continue to attract families and couples, especially given the strong showing in these household types. Rental yields near 4.1% and the achievable discount from asking prices suggest there is still room for negotiation and income-focused investment.
The limited size of the private rented sector could keep rental supply tight, which may help support rents at current levels. However, investors should be mindful of the recent change in capital values (-2.9%) and plan for potential fluctuations in the short term. Longer-term prospects look steady, especially if demand from families and professionals continues to hold up.
