A complete guide to property investment in Undy and Magor.
Last updated: 10 January 2026
Undy and Magor have seen steady growth over the past three years, with annualised growth of 5.1% and capital values up 16.2% over that period. However, the most recent twelve months have been less positive, with capital growth of -0.6%. The local market is dominated by owner-occupiers, sitting in the 88th percentile for this metric, and the area has a high proportion of couples, in the 91st percentile nationally. Affordability appears reasonable, with a price-to-income ratio of 5.5. Properties are taking their time to shift, averaging 92 days on the market, and annual sales are modest at 68.

Looking ahead, I expect Undy and Magor to remain a steady, if unspectacular, choice for property investors. The area’s strong professional base and high owner-occupation should support long-term stability, even if short-term price growth is muted. Affordability remains decent by regional standards, and the median asking rent for a 3-bedroom house of £1,425 looks competitive relative to the median asking sale price of £325,000.
However, with properties taking an average of 92 days to sell, investors should be prepared for a slower sales process. The local market is unlikely to deliver rapid gains in the next twelve months, but for those seeking income and stability, it still holds some appeal.
