Looking ahead, Treharris is likely to remain an affordable entry point for investors, especially those prioritising income over rapid capital growth. The annualised three-year growth of 1.0% suggests steady, if unspectacular, performance for those willing to take a longer-term view.
Rental yields should continue to appeal, especially given the median asking rent for a three-bedroom house of £800 compared to the median sale price of £192,500. However, the small size of the private rental market could limit opportunities to scale a portfolio. Investors should expect a stable but slow-moving market with a strong bias towards owner-occupiers and couples.
